Thu Dec 1 16:44:10 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
|
||
|
||
* cse.c (fold_rtx): When reordering constant args, insist on
|
||
manifest constants; regs with known contents won't do.
|
||
|
||
* i386.md (mulsi3): Don't use rtx_equal_p to compare regs.
|
||
|
||
* expr.c (move_by_pieces_1): Don't call change_address
|
||
if address is autoinc, since that may not be memory_address_p.
|
||
Subroutine-macro add_offset deleted.

|
||
|
||
* tm-m68k.h (PRINT_OPERAND): use new macros to print floats.
|
||
(ASM_OUTPUT_FLOAT_OPERAND): New macro.
|
||
(ASM_OUTPUT_DOUBLE_OPERAND): New macro.
|

|
||
|
||
Wed Nov 30 06:35:47 1988 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
|
||
|
||
* tm-ns32k.h (FUNCTION_{PRO,EPI}LOGUE): if no frame pointer,
|
||
do explicit push or pop insns.
|
||
|
||
* tm-genix.h (PRINT_OPERAND): Fix typo `file'.
|
||
Extedn decl for paren_base_reg_printed.
|
||
(MAIN_FUNCTION_PROLOGUE): Deleted.
|
||
(ASM_OUTPUT_EXTERNAL): Defined.
|
||
|
||
* c-parse.y (yyerror): Better error msg for unprintable char in token.
|
||
(primary => identifier): Set TREE_USED if implicit decl made.
|
||
|
||
* Makefile (cleanlinks): New target.
|
||
(INSTALL): New variable, has program used for installing files in sys.
|
||
|
||
* output-ns32k.c (print_operand_address): If addr is sum of 2 consts,
|
||
output ADDR first, then OFFSET.
|
||
|
||
* ns32k.md (addsi3): Allow adding const+reg with result in another reg.
|
||
|
||
* tm-seq386.h (FUNCTION_PROFILER): Provide overriding definition.
|
||
|
||
* tm-hp9k320.h: Alternate ASM_SPEC if using GAS.
|
||
Define STANDARD_STARTFILE_PREFIX if using GAS.
|

|
||
|
||
* optabs.c (init_optabs): Don't set up libcalls for ftrunc_optab
|
||
because (1) they aren't supported and (2) they are never used.
|
||
|
||
* gnulib.c (__builtin_saveregs): If not sparc, define the symbol anyway
|
||
to avoid a warning in ranlib.
|
||
|
||
Mon Nov 28 01:46:12 1988 Michael Tiemann (mdt at choctaw)
|
||
|
||
* c-parse.y (yylex): Typo, `=' for `==' making wide strings.
|
||
|
||
* sparc.md (various places): make sure that all patterns which store
|
||
can store using const0_rtx (i.e., make all operands to `st' %rx).
|
||
|
||
* output-sparc.c (various places): changed dispatches on SYMBOL_REF
|
||
to dispatches on CONSTANT_ADDRESS_P since we now recognize any CONST
|
||
(and not just SYMBOL_REFs). Don't recognize special case CONST for
|
||
output_block_move. Compiler doesn't have enough information to use
|
||
it.
|
||
|
||
* stmt.c (expand_fixup): If the control stack is nested within the
|
||
nesting stack, then no fixup is needed. Otherwise, compiler must
|
||
check for possible fixups between the current nesting stack and the
|
||
nesting stack that immediately contains the control stack.
|
||
|
||
* stmt.c (expand_function_start): functions which are nested use
|
||
DECL_CONTEXT. For these functions, test that their DECL_CONTEXT is
|
||
a LET_STMT node.
|
||
|
||
* tree.h: declare `build_offset_type'.
|
||

|
||
Don't try to use ldd/std if OP1 is a constant.
|
||
* sparc.md (movdi): Allow immediate args moved into general regs.
|
||
|
||
* c-decl.c (grokparms): Reject incomplete parm types even if just
|
||
declarating, not defining. Change types to error_mark_node
|
||
in both the PARM_DECL and the list of types.
|
||
|
||
* dbxout.c (dbxout_type): It's not a bug if a RECORD_TYPE
|
||
has a typedef as its TYPE_NAME. That happens in C++.
|
||
|
||
* Make each `asm' with operands record its source file/line
|
||
with reg-notes. It doesn't work to emit a special note before the insn
|
||
because the insn can be moved by loop_optimize.
|
||
* stmt.c (expand_asm_operands): New args FILENAME, LINE.
|
||
Record them in the insn, in reg notes.
|
||
* c-typeck.c (c_expand_asm_operands): New args, passed along.
|
||
* c-parse.y: Pass those args.
|
||

|
||
|
||
* reload.c (find_reloads): Don't clear BADOP for a reg letter
|
||
if the alternative ultimately doesn't allow any regs.
|
||
|
||
* reload.c (find_reloads): If an `asm' insn gets an error,
|
||
change it to a USE to avoid duplicate error msgs or later trouble.
|
||
|
||
* reload.c (find_reloads_address): Reloading a constant address,
|
||
specify Pmode as the mode for push_reloads, in case of CONST_INT.
|
||
|
||
* expr.c (emit_push_insn): Fix calc. of space needed when PARTIAL > 0.
|
||
Both scalar case and BLKmode case needed fixing.
|
||
|
||
* sparc.md (load/store constant address):
|
||
Moving DF from mem to cpu regs, don't go via %f0.
|
||
Don't use std/ltd if alignment is wrong or uncertain.
|
||
|
||
Sun Nov 27 10:34:53 1988 Michael Tiemann (mdt at yahi)
|
||
|
||
* reload.c (push_reload): Allow VOIDmode for INMODE, OUTMODE;
|
||
default the mode from the operand values.
|
||
|
||
* sparc.md: remove patterns which generate annulled branch insns.
|
||
They are correct, but those insns confuse GDB.
|
||
|
||
* tm-sparc.h (GO_IF_LEGITIMATE_ADDRESS):
|
||
Treat any constant address like a SYMBOL_REF.
|
||
* sparc.md: Check for CONSTANT_ADDRESS_P rather than SYMBOL_REF.
|
||
|
||
* sparc.md: Peepholes now accept SYMBOL_REF addresses.
|
||
The output routine can now split them properly even as delay insns.
|
||
|
||
* print-tree.c (dump): added entry for METHOD_TYPE and
|
||
METHOD_CALL_EXPR. Also added entry for WITH_CLEANUP_EXPR. Suggest
|
||
that we make first_rtl of WITH_CLEANUP_EXPR 2 instead of 1.
|
||
|
||
Sun Nov 27 00:15:33 1988 Michael Tiemann (mdt at yahi)
|
||
|
||
* print-tree.c (dump): added entry for OP_IDENTIFIER.
|
||
|
||
* tree.c (build_op_identifier): new function. Needed because
|
||
`build_nt' expects an "e" node, but OP_IDENTIFIER is an "x" node.
|
||
|
||
* store_layout.c (layout_record): use DECL_FIELD_CONTEXT instead of
|
||
DECL_CONTEXT.
|
||
|
||
* tree.h (DECL_FIELD_CONTEXT): new macro. Points to the type that a
|
||
FIELD_DECL is a member of. For C, this is just DECL_CONTEXT.
|
||
|
||
* tree.c (build_method_type): typo used "==" to assign basetype to
|
||
TYPE_METHOD_BASETYPE with predictably poor results.
|
||

|
||
to contain zero.
|
||
(gen_scc_insn): new function used by define_expands for
|
||
set-on-condition-code insns.
|
||
(output_delay_insn): now knows how to handle load and store
|
||
scheduling when the load or store operation takes two insns instead
|
||
of one. The rewrite is now understands is this:
|
||
|
||
sethi %hi(address),%g1 -> sethi %hi(address),%g1
|
||
ld/st [%g1+%lo(address)],%reg -> b target
|
||
b target -> ld/st [%g1+%lo(address)],%reg
|
||
nop -> ;; gone
|
||
|
||

|
||
now needed in expr.c.

|
||
if operand is const0_rtx or a register of specified mode.
|

|
||
* tree.c (build_method_type): now corresponds to defn in tree.def
|
||
expr.c (expand_call): removed code to get FUNCTION_TYPE from
|
||
METHOD_TYPE. This should probably be looked at harder.
|
||
|
||
* tree.def (METHOD_TYPE): Changed definition so that TREE_TYPE (m)
|
||
(where m is a METHOD_TYPE) is the type of the return value of the
|
||
method, not the FUNCTION_TYPE from which the METHOD_TYPE is derived.
|
||
|
||
* Makefile: Changed target of BINDIR from /usr/local to
|
||
/usr/local/bin.
|
||
|

|
||
|
||
* tm-sparc.h (GO_IF_LEGITIMATE_ADDRESS): Allow any SYMBOL_REF.

|
||
|
||
* tm-m68k.h (HARD_REGNO_MODE_OK): Disallowed d7:a0 as an allowable
|
||
pair of registers to hold a double value. This is correct for the

||
defining a new regclass.

||
* loop.c (loop_optimize): Mention invalid multiple-entry loops in log.

OLDEQUIV (a register that holds the same value).
|
||
|
||
* tm-m68k.h (LEGITIMIZE_ADDRESS): Don't give force_operand a target.

||
which can confuse cse.
|
||
|
||
* loop.c (consec_sets_invariant_p):
|
||
If invariant_p ever returns 2, we return 2.

New arg is # of consecutive sets to look for,

|
||
even if the parm came in a register; and use that stack space
|
||
if the parm needs to be addressable or is BLKmode.
|
||
Rearrange to simplify conditionals.

`qty_...' vectors' elements for hard-reg-numbers now aren't used.
|

`reg_qty' elements for hard-reg numbers now aren't used,
|
||
and the element for a pseudo is never a hard-reg number.
|
||
(local_alloc): No need to reset those elements.
|
||
No need to reset elements out of range of prev block's NEXT_QTY.
|
||
(reg_is_born, reg_is_set, wipe_dead_reg):
|
||
Divide labor in same way for hard regs and pseudos;
|
||
simplify using fact that locality-to-basic-block has been precomputed
|
||
and recorded in reg_qty; avoid refs to reg_qty[HARDREG].
|
||
(reg_is_born, wipe_dead_regs): Block-number arg no longer needed.
|
||
|
||
* local-alloc.c (combine_regs): Remove old code for tying hard regs
|
||
to pseudos; great simplification results.
|

(cse_insn): Don't call find_reg_note if REG_NOTES is 0.
|
||
|
||
* cse.c (cse_insn): Store modified SET_SRC even if there's a REG_EQUIV.

|
||
equivalent value; now it is in the REG_EQUIV note.
|
||
|
||
* stmt.c (expand_asm_operands): If NINPUTS is 0, make vec of no elts.
|
||
* regclass.c (reg_scan_mark_refs): Don't lose if XVEC (x,i) is 0.

||
* cse.c (cse_insn): Return very early for (set (reg) (call...)).
|

(cse-insn) Old code to add REG_WAS_0 note wasted time but did nothing.
|
||
|
||
* expr.c (clear_pending_stack_adjust): Really do clear it,
|
||
if current fcn doesn't want to be inline.
|
||
|
||
* cse.c (cse_insn): Speedup: instead of safe_hash, use canon_hash

||
or HASHREG.

|
||
equivalent value is the same as the SET_SRC of the insn.
|
||
|
||
* flow.c (life_analysis): Don't call volatile_refs_p for a CALL_INSN;
|
||
just assume value is 1.
|
||
(propagate_block): Don't call mark_{used,set}_regs for a stack-pop
|
||
since if it isn't dead it has no effect on any useful life data.
|
||
(mark_set_1): Return quickly if setting stack-ptr, and almost as
|
||
quickly if setting any hard reg.
|
||
(mark_used_regs): Likewise for refs.
|
||
Also don't scan the vector of an ADDR_VEC or ADDR_DIFF_VEC.

||
(volatile_refs_p): Likewise.
|
||
|
||
* varasm.c (output_constant): Discard NOP_EXPR and CONVERT_EXPR
|
||
in integer case (they were for casting a pointer).
|
||
|
||
* parse.y (compstmt_or_error): Parse a compstmt after ignoring error.
|
||
Use this for fctn body so that an error after store_parm_decls
|
||
won't recover to xdecls and call store_parm_decls again.
|
||
Typical cause was missing semi at end of last parmdecl.
|
||
|
||
* parse.y: Add missing semicolons in actions.
|
||
(yylex): Don't use yylloc.

an equivalent value is needed. Equivalence must be good in that mode.
|
||
In addition, notice overlap with multiword register modes.
|
||
Simplify, knowing that registers have already been renumbered.
|
||
It was invalidating memory-goals too easily; setting a reg
|
||
only invalidates memory-goal if its address varies.
|
||
* reload.c, reload1.c, jump.c: Calls pass the new argument.
|
||
|
||
* cccp.c: For correct ANSI, must reject `$' in identifiers.
|
||
(dollars_in_ident): Variable says whether to allow them.
|
||
(rescan): Handle `$' as randomchar if that's 0.

(main): dollars_in_ident is set to 0 by -$, to 1 by -traditional.
|
||
(rescan, do_define): Delete former pedantic warnings for `$'.
|
||
(initialize_char_syntax, initialize_builtins): Inits split to two
|
||
functions; former is called after options are scanned
|
||
so `$' is in is_idchar conditionally.
|
||
* gcc.c: For -ansi, pass -$ to cccp.
|
||
* toplev.c, flags.h: Define dollars_in_ident.
|
||
* parse.y (yylex): Treat $ as punctuation unless dollars_in_ident.
|
||
Delete old pedantic warning about $.
|
||
* tm-vms.h: Define DOLLARS_IN_IDENTIFIERS as 1.
|
||

* cccp.c (rescan): Preprocessing numbers can have signs, after `e'.
|
||
|
||
* integrate.c (expand_inline_function): Abort, don't return failure,
|
||
if max_regno is too low. I believe this can't happen.
|
||
|
||
* typecheck.c (build_binary_op_nodefault):
|
||
For ordered comparisons, no pedantic warning about void *.
|
||
For MAX, MIN, ditto, and also don't allow pointer vs 0.

* gcc.c (fatal): Add missing arg to delete_temp_files.
|
||
|
||
* cccp.c (dump_defn_1): Add missing arg to skip_quoted_string.
|
||
|
||
* reload.c (find_reloads): If constraints don't fit in an `asm',
|
||
print error instead of aborting.
|
||
|
||
* regclass.c (reg_class_record): Ignore `&' in constraint.

|
||
* toplev.c, varasm.c, final.c: Use the enum constants where appro.

|
||
put each in the appropriate conditional {SDB,DBX}_DEBUGGING_INFO.
|
||
|
||
* toplev.c (main): Delete -noreg option; it's now the default.
|
||
Make -O an alias for -opt. Rename -g to -gg. -g is alias for -G.
|
||
Accept and ignore -Wtrigraphs.
|
||
* gcc.c: Simplify the specs.
|
||
|
||
* toplev.c (compile_file), tm-*.h:
|

ASM_FILE_START is now a statement, not just a string to be output.
|
||
Output it *after* determining the real source file name.
|
||
|
||
* fold-const.c (fold): Simplify x >= CST to x > CST-1 (CST positive).
|
||
To simplify this, canonicalize relationals to put constat last.
|
||
|
||
* decl.c (duplicate_decls): Make a 2nd errmsg to show previous decl.
|
||
|
||
* cccp.c (file_size_and_mode): Delete temporary VMS bootstrap patch.

|
||
|
||
* regclass.c (init_reg_sets_1): Part of init_reg_set is put in this
|
||
new fn which is called after options are scanned.
|
||
Now CONDITIONAL_REGISTER_USAGE can depend on the options.
|
||
(fix_register): Just alter the data that init_reg_sets_1 will look at.
|
||
|
||
* reload1.c (reload): Don't complain if two different but tieable
|
||
modes require groups of the same regclass (assuming same size group).
|
||
|
||
* cccp.c: Add 3rd arg to all `open' calls.
|
||
|

|
||
of something that doesn't have one.
|
||
|
||
* reload1.c (alter_frame_pointer_addresses): frame pointer can
|
||
occur by itself, not just inside a PLUS.
|
||
(reload): Call eliminate_frame_pointer before reload_as_needed.
|
||
Otherwise the latter can make reload insns that copy the frame ptr
|
||
to a data reg, but 68k can't copy sp+const to a data reg.
|
||
|
||
* decl.c (implicitly_declare): Always save the implicit decl
|
||
permanently. Reuse an old one if it exists.

|
||
* stor-layout (layout_{type,decl}): Call variable_size.

|
||
`a' in `foo (a,i) int i; struct {int x[i];} a;', so report an error.
|
||
|
||
* flow.c (insn_dead_p): insn that makes stack bigger is never dead.
|
||
* combine.c (try_combine): Don't splice out stores into stack ptr.

|
||
via a local extern decl before its definition.

* expr.c (expand_call): If need to mark a fcn decl addressable,
|
||
mark the identifier addressable also.
|
||
* typecheck.c (mark_addressable): If marking fcn addressable,
|

mark the identifier as well.
|
||
* decl.c (start_function): If identifier was marked addressable,
|
||
propagate it to the function.
|
||
|
||
* parse.y (yylex): Check for ERANGE after atof is called.
|
||
(Sun doesn't report ERANGE.)
|
||
|
||
* loop.c (may_trap_p): Any floating arithmetic may trap.
|
||
|
||
Wed May 25 00:03:34 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* parse.y: Delete `noalias'.
|
||
(asm_operand): Don't allow this to be empty.
|
||
(asm_operands): Do allow this to be empty.
|
||
|
||
* reload.c (operands_match_p): Don't let REG and SUBREG match
|
||
if the reg isn't a hard reg.
|
||
No longer nec. to check reg_renumber, now that reload
|
||
substitutes the hard regno.
|
||
|
||
* reload1.c (reload): Counting existing spilled groups,
|
||
check HARD_REGNO_MODE_OK so we don't get fooled by an odd-even pair.
|

(n_spills): This var is now static, no longer passed as arg
|
||
within the file.
|
||
|

(reload_reg_class_lower): Handle all group-reloads before solitaries.
|
||
(choose_reload_targets): therefore #if 0 the special code for
|
||
finding solitary registers that aren't suitable for groups.
|
||
But fix two bugs in it: braino deciding whether a reload
|
||
is looking for 1 register (not a group). Use CLASS_MAX_NREGS.
|
||
Also braino deciding whether a spill reg can be in a group.
|
||
Did not fix bug that it fails to test HARD_REGNO_MODE_OK,
|
||
so it might split up an even-odd pair.
|
||
|
||
* vax.md: Special patterns for 8 and 16-bit fields, to make
|
||
move-insns (like the ones for the 68k).

|
||
* integrate.c (expand_inline_function): If inline fcn was declared to
|

return QI, but actually computes an SI, use SImode for INLINE_TARGET
|
||
but actually return a QI.
|
||
|
||
* varasm.c (force_const_mem): Failed to determine alignment bdry
|
||
from machine mode.

||
* fold-const.c (combine): Typo in MIN_EXPR, MAX_EXPR.
|
||
|
||
* reload1.c (reload): Was counting insn_groups as total size of groups,

|
||
if i3 uses that reg.

Use reg_or_mem_operand for constraint in op1 of divide insns;
|
||
a constant there causes regclass to screw up.
|
||
Split alternative constraints on the bit-field insns to avoid
|
||
out-of-range operands in exts, inss. Some cases of extraction
|
||
can be done faster via memory.

* flow.c (mark_set_1): When adding a REG_DEAD note, inc reg_n_deaths.
|
||

|
||
if the reg's class is contained in the qty's class
|
||
(as well as if the reg's class contains the qty's class as before).

this can occur when we drop through into a basic block whose need was 0
|
||
(and so whose local pseudos were not spilled).
|
||
|
||
* gcc.c (main): If -v, print gcc's own version; also no error msg
|
||
if no input files.
|
||
|
||
* loop.c (may_trap_p): Mem ref to nonconstant address may trap.
|
||
(scan_loop): Check may_trap_p only when insn is in other respects ok.

|
||
|
||

(not including big-endian width-change correction).
|

||
* typecheck.c (shorten_compare): Set unsignedp[01] right in case
|
||
where get_narrower makes no change.
|
||
(build_binary_op_nodefault): Likewise for shortening shifts.
|
||
|
||
* stmt.c (expand_end_case): Use type_for_size to get the type
|
||
to convert the index to, since `int' is wrong if -mshort.
|
||
|
||
* decl.c (grokdeclarator): Don't check PARM type for completeness.
|
||
(grokparms): If fn definition, check all parm types for completeness.
|
||
(store_parm_decls): Likewise.
|
||
|
||
Tue May 10 22:42:13 1988 Richard Stallman (rms at corn-chex.ai.mit.edu)
|
||
|
||
* typecheck.c (store_init): For invalid init, store error_mark_node.
|
||
* varasm.c (assemble_variable): Ignore error_mark as an init.
|
||
* stmt.c (expand_decl): If init is error_mark, init to 0 if possible.
|
||
This avoids a spurious "uninitialized variable" warning.

|
||
|
||
* tm-hp9k320.h: Define STRUCTURE_SIZE_BOUNDARY.
|
||
|
||
* decl.c (get_parm_info): Replaces get_parm_types. Returns a tree_list
|
||
containing parmdecls and tag list as well as type list.
|
||
(grokparms): Accept that tree_list as argument.
|

(grokdeclarator): Calling grokparms, say "not a definition" for the
|
||
function declarators for arg or value types within a definition.
|
||
|
||
* parse.y: Call get_parm_info.
|
||
(parmlist_or_identifiers): If identifiers, make a tree_list
|
||
like the one get_parm_info returns.
|
||
|
||
Fri May 6 16:44:19 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* m68k.md (casesi): Delete template aside from match_operand's.
|
||
|
||
* tm-encore.h: New file from Robert Brown.
|
||
|
||
* ns32k.md: Use %c in some addr insns.
|
||
(tst*): Use {d,f,}const0_rtx to make the constant 0; OS-independent.

||
|
||

|
||
|
||
* explow.c (memory_address): Ignore flag_force_reg unless optimize.
|
||
Also ignore it for addresses of stack slots (avoid invalid REG_EQUIVs).
|
||
|
||
* typecheck.c (digest_init): If traditional, allow `char x[100]=0;'.
|
||
|
||
* tree.c (get_unwidened): Don't alter a COMPONENT_REF if
|
||
innerprec equals the precision of the existing type.
|
||
It was changing pointers to integers.
|
||
|
||
* m68k.md (movdi): Put all fpregs in separate constraint alternatives
|
||
and handicap them so spill reg won't be an fp reg.
|
||
|
||
* parse.y (yyerror): Use the arg as part of the error message.
|
||
|
||
* decl.c (start_function): Give the RESULT_DECL type int rather
|
||
than char or short.
|
||
* typecheck.c (c_expand_return): Convert value from fn's return type
|
||
to the RESULT_DECL's type.
|
||
|
||
* Avoid generating dbx xrefs to enums, since dbx loses on them.
|
||
Do this by outputting all types in order of definition.
|
||
This is done only for top-level types; problem remains for local ones.
|
||
|
||
* decl.c (finish_decl): Do rest_of_decl_compilation for TYPE_DECLs.
|
||
* toplev.c (rest_of_decl_compilation): Do dbxout_symbol for them.
|

|
||
For a TYPE_DECL, ignore it if the type was already output
|
||
and its preferred name is the TYPE_DECL. Else output type in full.

|
||
* decl.c (pushdecl): Don't prefer typedef names to type tag names.
|
||
|
||
* stor-layout.c (chain_type): Build chain in forward order.

|
||
* tm-3b1.h (ASM_OUTPUT_CASE_LABEL): Error getting length of table.
|
||
|
||
* tm-3b1.h: #define SGS_3B1 was missing.
|
||
|

||
* parse.y: Don't use the Bison @ construct, since it makes parser slow.
|
||
|
||
* decl.c (finish_function): Delete FILENAME and LINE args.
|
||
|
||

|
||
|
||
* toplev.c (main): Ignore `-Wcomment'.

|
||
|

* decl.c (finish_struct): Don't ever make DECL_ALIGN smaller.
|
||
|
||
* decl.c: Rename min, max to MIN, MAX.
|
||
|
||
* typecheck.c (convert_for_assignment): Avoid warning if assigning
|
||
a `void *' from a `const void *'.
|
||
|
||
* combine.c (FAKE_EXTEND_SAFE_P): Turn off for mem refs; avoid faults.
|
||
|
||
Mon May 2 07:28:27 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* tm-vax.h: Support -mg switch to use g-float instead of d-float.
|
||
New macros TARGET_G_SWITCH, ASM_DOUBLE_CHAR.
|
||
Changes in TARGET_SWITCHES, ASM_OUTPUT_DOUBLE.
|
||
Define code `#' for PRINT_OPERAND.
|
||
* vax.md: use `#' in opcodes for doubleword float.

* tm-vax.h: Define UDIVSI3_LIBCALL and UMODSI3_LIBCALL.
|
||
|
||
* cccp.c (main, do_include): Implement -I- switch.

* jump.c (jump_optimize): When hunting NOTE_INSN_FUNCTION_END,
|
||
skip final RETURN (found on the vax).
|
||
|
||
* toplev.c (main): -Wall is equiv to all -W switches combined.
|
||
|
||
* stmt.c (expand_decl, expand_end_bindings,
|
||
expand_{start,end}_function). The -noreg treatment of `register' vars
|
||
is extended to vars used as addresses of vars in memory (varying-size
|
||
structures).
|
||
(use_variable): Emit USE for regs used in specified rtx.
|
||
|
||
* cse.c (fold_cc0): Stack-frame addresses are always nonzero.
|
||
(fold_rtx): 0200 bit in prev_insn_cc0 means only zeroness is known.
|
||
|
||
* parse.y (parmlist): poplevel needs 3 args.
|
||
|
||
Sun May 1 07:20:34 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* decl.c (start_function): typo checking for incomplete return type.
|
||
|
||
* emit-rtl.c (restore_reg_data): If a pseudo appears nowhere,
|
||
don't leave its slot empty; create a pseudo for that slot.
|
||
|
||
* Version 1.21 released.
|
||
|
||
* expr.c (expand_call): Merge duplicate code for structure_value_addr.
|
||
|
||
* emit-rtl.c (restore_reg_data): Delete error check; it's legit for
|
||
a pseudo reg to appear nowhere in the rtl.
|
||
|
||
Sat Apr 30 07:35:31 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)

||
|
||
* integrate.c (copy_rtx_and_substitute): Fix typo for arg_pointer_rtx.
|
||
|
||
* decl.c (poplevel): Undo previous change with #if 0.
|
||
|
||
* stmt.c: `struct nesting' now records the depth on the stack.
|
||
Each expand_start... must update and record the depth;
|
||
each expand_end... uses macro POPSTACK to pop.
|
||
This way, if a level isn't explicitly popped, it won't cause
|
||
circular structure.
|
||
|
||
* dbxout.c (dbxout_type): Replace with main variant only if incomplete.
|
||
|
||
* typecheck.c (build_unary_op): Test of `pedantic' was backwards.

||
|
||
Fri Apr 29 08:41:06 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* integrate.c (copy_decl_tree): New arg is depth in recursion.
|
||
Always discard the outermost LET_STMT being copied; never discard any
|
||
others. This way the copied LET_STMTs correspond to the copied NOTEs.
|
||
|
||
* varasm.c (decode_rtx_const): For SYMBOL_REF, use string address
|
||
not address of the rtx. Library fns have only one copy of the name
|
||
but many copies of the SYMBOL_REF.
|
||
|
||
* expr.c (emit_call_1): New arg OLD_ARGS_SIZE is used to reset
|
||
current_args_size.
|
||
(emit_library_call, expand_call): Pass new arg; don't restore it here.
|
||
|
||
* flow.c (life_analysis): Don't mark sp live at end if fn is empty.
|
||
|
||
* parse.y (parse_or_identifiers_1): Handle `error' in here, not in
|
||
callers notype_declarator etc. Also read the closeparen here.
|
||
|
||
Thu Apr 28 12:43:52 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* expmed.c (expand_shift): In extzv strategy, handle the operand
|
||
predicates for operands 0, 1 and 3. (Not needed for 2.)
|
||
* vax.md: extzv pattern for SImode op1 must recognize general_operand
|
||
since the pattern named "extzv" allows them.
|
||
|
||
Wed Apr 27 00:52:44 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* expr.c (emit_call_1): New arg NEXT_ARG_REG describes # regs
|
||
used for passing args.
|
||
(emit_library_call, expand_call): Provide that argument.
|
||
|
||
* explow.c (round_push): New fn: round arg up to STACK_BOUNDARY.
|
||
* expr.c (expand_builtin): Use round_push on size for __builtin_alloca.
|
||
* stmt.c (expand_decl): Likewise for variable-size objects.
|
||
* expr.c (expand_call): Likewise for args_size.var.
|
||
Also use STACK_BOUNDARY to round a constant arg-block size.
|
||
Pass emit_call_1 that rounded value.
|
||
(emit_library_call): Round arg_size with STACK_BOUNDARY.
|
||
* tm-spur.h: Define STACK_BOUNDARY instead of ROUND_CALL_BLOCK_SIZE.
|
||
* tm-m68k.h: Define STACK_BOUNDARY as 16.
|
||
|
||
* expr.c (emit_call_1): Don't change current_args_size.
|
||

|
||
to ambient value, after calling emit_call_1.
|
||
|
||
* tm-hp9k320.h: Don't define USG here.
|
||
* config-hp9k3.h: New file. USG defined here.
|
||
|
||
* tm-3b1.h: #undef ASM_OUTPUT_ASCII (a defn came from tm-hp9k320.h).
|
||
|
||
* decl.c (grokdeclarator primarily): Cast all RID_... to (int) before
|
||
using them in arithmetic. Placates CC on Sequent.
|
||
|
||
* emit-rtl.c (emit_jump_insn): Return proper value, for a SEQUENCE.
|
||
* emit-rtl.c (emit_call_insn): Handle SEQUENCE like emit_jump_insn.

|
||
|
||
* jump.c (jump_optimize): Don't do April 20 optimization on first
|

Sun Apr 24 02:45:28 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|

||
based on an initializer.
|
||
(finish_decl): Use complete_array_type.
|
||
* parse.y (expr_no_commas): When parsing a constructor,
|
||
Use complete_array_type on constructors for incomplete array types.
|
||
|
||
* typecheck.c (digest_init, store_init_value,process_init_constructor):
|
||
It's now TREE_STATIC, not TREE_ADDRESSABLE, that records that all elts
|
||
in a CONSTRUCTOR are simple constants.
|
||
(digest_init): A CONSTRUCTOR with non-null type is treated as ordinary
|
||
expression, not as a braced initializer.
|
||
Allow init of an array from an array-valued expr; warn if pedantic.
|
||
* expr.c (expand_expr, CONSTRUCTOR case): Put in memory only if static.
|
||
Was making an extraneous level of MEM; output_constant_def does it all.
|

|
||
(default_conversion): Likewise.
|

|
||
* global-alloc.c (reg_dead_p): Deleted.
|
||
(global_conflicts): Use find_regno_note instead of reg_dead_p.
|
||
|
||
* final.c (final) Use find_reg_note to look for a REG_INC.
|
||
* combine.c (insn_has_inc_p): deleted; callers use find_reg_note.
|
||
(try_combine): Use find_reg_note whenever looking for a REG_INC.
|
||
(regno_dead_p, remove_death): Check the REG_NOTE_KIND before assuming
|

|

|
||
|

|
||
|
||
* expr.c (expand_builtin): For alloca, round arg up to multiple
|
||
of PARM_BOUNDARY. Also to convert it to Pmode unless it already is.

|
||
|
||
Fri Apr 22 00:22:59 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* cccp.c: Text following #else or #endif is just a warning.
|
||
(rescan): Digit-case was dropping into the $-case; reorder.
|
||
|
||
* cccp.c (rescan): Comment start when -traditional was output as
|
||
`/*'; should be nothing.
|
||
|
||
* jump.c (jump_optimize): Fix prev change:
|
||
do nothing if range1end == range2end;
|
||
don't lose any NOTEs when splicing.
|
||
|
||
* flow.c (propagate-block): For CALL_INSN, clobber the call-used regs
|
||
only after mark_set_regs is done; avoids confusion about lifespan

|
||
* cccp.c (main, rescan): If -Wcomment, warn if `/*' inside comment.

|
||
|
||
* integrate.c (expand_inline_function): Insn to copy a subroutine's
|
||
return-value was being output twice, once incorrectly.
|
||
|
||
* reload.c (find_equiv_reg): A stack-push insn does not invalidate
|
||
an equiv for a goal in memory.
|
||
Any other write to memory does invalidate any goal in memory
|
||
(PARALLEL case failed to check for this).
|
||
|
||
* expmed.c (expand_shift): In the extzv clause, force shifted value
|
||
out of memory if -fforce-mem.

* stmt.c (assign_parms): Round current_function_pretend_args_size up.
|
||
|

|
||
When a named type is first seen inside another type, output an xref
|
||
and let the real definition come out later.
|
||
It is strange that Sun dbx has sometimes appeared to demand
|
||
one strategy and sometimes appeared to demand the other.
|
||
|
||
* typecheck.c (convert_for_assignment): Allow conversion to or from
|
||
`const void *', etc., unless pedantic.
|
||
|
||
* decl.c (get_parm_types): For `foo (void){}', set last_function_parms
|
||
to nil so store_parm_decls won't lose.
|
||
|
||
* combine.c (subst): (plus (plus X N) -N) => X.
|
||
|
||
* explow.c ({anti_,}adjust_stack): Don't make a copy of

`stack_pointer_rtx'.
|
||
|
||
* integrate.c (expand_inline_function): Typo testing for the
|
||
USE that indicates a CALL_INSN's value is being returned.
|
||
|
||
* expr.c (expand_builtin, alloca case): Copy arg to reg before
|
||
adjusting stack, to avoid invalid insns on some machines.
|
||
|
||
Wed Apr 20 00:15:14 1988 Richard Stallman (rms at rice-krispies.ai.mit.edu)
|
||
|
||
* typecheck.c (build_binary_op_nodefault): When shortening,
|
||
get_narrower may make no change because ARGn is already narrow.
|
||
In this case, set UNSIGNEPn from ARGn's type.
|
||
|
||
* typecheck.c: Rename ARG1,ARG2 to ARG0,ARG1, etc. in several fns.
|
||

|
||
register is autoincremented.
|
||
|
||
* parse.y (structsp): suspend_momentary before start_enum;
|
||
else some nodes made by start_enum might be momentary.
|
||
|
||
* stmt.c (expand_start_case): New arg is nominal type for comparison
|
||
(which is the promoted type of the index expression).
|
||
(pushcase): Always convert VALUE to that nominal type
|
||

|
||
* parse.y (case stmt): Promote each case-value before pushcase.

Wed Apr 13 12:43:08 1988 Chris Hanson (cph at kleph)
|
||
|
||
* tm-hp9k320.h: Define ASM_FORMAT_PRIVATE_NAME. HPUX asm forbids

|
||
to extend Y and store in X.
|

* Support variable-sized structures (containing var-sized arrays).
|
||
|
||
* stmt.c (assign_parms): Handle parms whose size varies.

||
Convert variable size from units of DECL_SIZE_UNIT to units of bytes.
|
||
|
||
* expr.c (emit_push_insn): Arg ARGS_SO_FAR is now an rtx.
|
||
Pay attention to ARGS_ADDR even if machine has push insns.
|
||
(expand_call): Handle variable-sized arguments.
|
||
If have any such, push entire arg-block in advance.
|
||
Record each arg's offset during first loop and don't change args_size
|
||
during the actual pushing loop; this way the actual pushing loop
|
||
works regardless of arg-order if arg-block was pushed in advance.
|
||
(push_block): Copy SIZE to reg unless it's a reg or constant.
|
||
|
||
* expmed.c (expand_divmod): If converting CEIL_DIV to FLOOR_DIV,
|
||
make new pseudo for incremented value, to help cse understand.

|
||
* expr.c (expand_expr, ARRAY_REF): Likewise.
|
||
* tree.c (type_precision): Prec of a pointer is POINTER_SIZE.

(convert_to_integer): Pointers convert via an int of that width.
|
||
|
||
* decl.c (init_decl_processing): Use INT_TYPE_SIZE, if def,

|
||
|
||
* tm-vax.h (STRUCTURE_SIZE_BOUNDARY): Make this always 8, for BSD.
|
||
* tm-ultrix.h: New file, overriding STRUCTURE_SIZE_BOUNDARY.
|
||
[This change has been taken out; tm-ultrix.h is now equivalent to
|
||
tm-vax.h. I must have been confused when testing PCC.]
|
||
|
||
* integrate.c (expand_inline_function): Don't let inline_target
|
||
be nonzero in BLKmode.
|
||
|
||
* decl.c (grokdeclarator): Const array parm becomes ptr-to-const.
|
||
|
||
Thu Apr 7 05:02:41 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* genoutput.c (bcopy, bzero): Renamed to mybcopy, mybzero
|
||
so variation in C library and config.h won't affect the results.
|
||
* genrecog.c (bzero): likewise.
|
||
* genextract.c (bcopy): Fn deleted; used only in a string constant.
|
||
|
||
* varasm.c (force_const_mem): Fix typo in arg decl.
|
||
|
||
* toplev.c (compile_file): init_file with main_input_filename

|
||
|
||
Wed Apr 6 14:06:38 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* expr.c: Delete SLOW_ZERO_EXTEND conditionals added March 3.

||
Now that enums types can be unsigned, this isn't needed.
|
||
|
||
* emit-rtl.c (emit_jump_insn): Handle SEQUENCEs.
|
||
|
||
* genemit.c (gen_expand): Use emit_jump_insn, emit_label, emit_barrier
|
||
when the insn rtl requires it.
|
||
|
||
* m68k.md (subsi3): Prefer to avoid reverse-subtraction alternative.
|
||
|
||
* stmt.c (expand_end_case): Let CASE_DROPS_THROUGH control what to

|
||
Don't call validate_else if do_else or do_endif will detect error.
|
||
|
||
* Bug: inline fcns can refer to the return reg with a strict_low_part
|
||
which confuses expand_inline_function. Fix is to change return reg
|
||
into inline_target *everywhere* except in or right after a call.
|
||
* integrate.c (copy_rtx_and_substitute): Delete special case for SET.
|
||
Replace return-value hard regs with INLINE_TARGET in all contexts.
|
||
(expand_inline_function): special handling for insn after a CALL_INSN

between the CALL_INSN and the value-copy.
|
||
|
||
* expr.c (emit_call_1): New name for gen_call_1.
|
||
|

||
* tree.def: New tree-code RTL_EXPR holds a sequence.
|
||
* expr.c (expand_expr): Handle RTL_EXPR by emitting the sequence.
|
||
* stmt.c (expand_{start,end}_stmt_expr): Use emit_to_sequence
|
||
to make a sequence from everything within the ({...}).
|
||
(expand_{start,end,emit}_delayed_expr): Delete these functions.
|
||
* parse.y (`for'-statements): Don't call them; nothing special needed.
|
||
|
||
* parse.y (yylex): Handle syntax L"..." and L'...'
|
||
(combine_strings): Handle wide strings being combined.
|
||

||
|
||
* parse.y: Define keyword `noalias'.
|
||
* parse.h: Define RID_NOALIAS.

|
||
(get_parm_types): Special case for list of one decl with type void.

since the precision has not changed.
|
||
* stor-layout.c (layout_type): Allow enum types to be unsigned.
|
||
|
||
* emit-rtl.c (unshare_all_rtl): Unshare contents of all reg-notes.

|
||
|
||
* typecheck.c (shorten_compare): When data type determines the value,
|
||
eval the nonconstant arg anyway if it has side effects.
|
||
(build_conditional_expr): When merging `foo *' with `void *',
|
||
also allow `const void *'. Result type has merged set of qualifiers.
|
||
(qualify_type): Merge qualifiers of two types.
|
||
|
||
* decl.c (get_parm_types): Store any tags defined in parmlist
|
||

|
||
(store_parm_decls): Add those tags into the current binding level.
|
||
|
||
* parse.y (parmlist, parmlist_or_identifier): Pass 0 to pushlevel;
|
||
no binding levels in C should be transparent to tags.
|
||
|
||
* 3b1 support:
|
||
* tm-3b1.h: New file.
|
||
|
||
* m68k.md: Add HPUX_ASM conditionals for shift-by-24-and-compare.
|
||
In one of the dbra patterns, a HPUX_ASM conditional was backwards.
|
||
(movhi) [SGS_3B1]: Define the LI... label as in MIT syntax.
|
||
(addsi3) [SGS]: Syntax for base-displacement differs from MOTOROLA.
|
||
(subsi3) [SGS]: likewise.
|
||
(tablejump) [ASM_OUTPUT_CASE_LABEL]: Use 6, not 2, as displacement.
|
||
This assumes ASM_OUTPUT_CASE_LABEL on 68k is used for a `swbeg'.
|
||
|
||
* final.c (final): Use ASM_OUTPUT_CASE_LABEL (if defined) to output
|
||
any CODE_LABEL followed by an ADDR_VEC or ADDR_DIFF_VEC.
|
||
It has 4 args; 4th is the insn which is the ADDR_VEC or ADDR_DIFF_VEC.
|
||
|
||
* tm-*.h for 68000 (PRINT_OPERAND_ADDRESS): For unscaled indexing in
|
||
fetch from a branch table, use L and LI symbols as in the scaled case.
|
||
|

|
||
|
||
* integrate.c (output_inline_function): Real start of function

||
is FIRST_PARM_INSN, not FIRST_FUNCTION_INSN.
|
||
|
||
* tree.c (build_string): String contents must be saveable (for
|
||
inline fcn).
|
||
|
||
* cse.c (cse_insn): Don't forget to set dest_hash_code when dest
|
||
is a stack slot (and so its address is not being optimized).
|
||
|
||
* emit-rtl.c (restore_reg_data_1): reg_rtx_no must be 1+ largest REGNO.
|
||
|
||
* m68k.md (non-SImode bit-field insns): Change constraint to "o,d"
|
||
so a nonoffsetable memref is handled by reloading its address
|
||
but a register can still be handled.
|
||
|
||
* toplev.c (main): Execute OVERRIDE_OPTIONS, if it's defined.
|
||
|
||
Sat Apr 2 00:55:21 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
|
||
|
||
* expr.c (convert_move): Handle a SUBREG in direct truncation case.
|
||
|
||
* cse.c (lookup_for_remove): Don't test machine mode of registers:
|
||
Storing in (REG:SI 0) invalidates (REG:DF 0).
|
||
|
||
* decl.c (pushlevel): New arg, nonzero means this level is for
|
||
variables only, not for tags. All calls changed.
|
||
(lookup_tag): Even if THIS_LEVEL_ONLY, skip variables-only levels.
|
||
(pushtag): Define it in the first non-variables-only level.
|
||
|
||
* dbxout.c (dbxout_type): Undo Mar 29 change, in the DBX_NO_XREFS case.
|
||
So now each struct or union will contain only nameless cross-refs
|
||
to any others it uses. The prior change is still in effect when
|
||
DBX_NO_XREFS is not defined.
|
||
|
||
* Implement variable array bounds for parameters.
|
||
* decl.c (poplevel): Don't crash if DECL_NAME gives 0.
|
||
* typecheck.c (comptypes): A variable array bound matches anything.
|
||
* parse.y (parmlist): Call pushlevel, then pushdecl each parm as it
|
||
is parsed; then poplevel after using get_parm_types to extract the
|
||
results of the parmlist.
|
||
* decl.c (get_parm_types): New function; reverse the current decls,
|
||
put them in last_function_parms, and return a list of their types.
|
||
(grokparms): Arg is now an idlist or a typelist. Do nothing if latter.
|
||
(push_parm_decl): New function, like {start,finish}_decl combined
|
||
for a parm in a parmlist.
|
||

||
* expr.c (prepare_call_address): New function; given two rtx's
|
||
for function and context, copy the context to the right hard reg,
|

Let them handle USEs at end of scope of formal parameter copies.
|
||
|
||
* integrate.c (expand_inline_function): In a new-style CALL_INSN,

||
(set (reg ...) (call ...)), not just (call ...).
|
||
|
||
* *.md: Define a "call_value" insn pattern.
|
||
|
||
* tm-m68k.h, tm-vax.h, tm-ns32k.h: (NOTICE_UPDATE_CC):

These insns invalidate the CC.
|
||
|
||
* local-alloc.c (combine_regs): #if 0 special treatment of
|
||
function value hard reg.

|
||
|
||
* loop.c (count_loop_regs_set): Move CALL_INSN into a separate
|

clause. When finding regs that are function addresses, handle
|

both old and new format call insns.
|
||
|
||
* flow.c (insn_dead_p): A SET that contains a CALL can't be dead.
|
||
(volatile_refs_p): Any CALL constitutes a volatile ref.
|

|
||
a call_value insn which stores in VALREG.
|

|
||
unless expression has type `void'.
|
||
|
||
* expr.c (emit_library_call): New 2nd arg OUTMODE is mode of result.
|

|
||
* cse.c (canon_hash): Consider all CALL rtx's volatile.

|
||
|
||
* dbxout.c (dbxout_type): Never output a cross-ref for
|
||
a type whose definition is known. Sun dbx won't accept them.

Mon Mar 28 12:34:46 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
|
||

even if not pedantic, but not if traditional.
|
||
|
||
* typecheck.c (convert_for_assignment): Don't warn about
|
||
pointers volatile * vs nonvolatile * if -fvolatile specified.
|
||
|
||
* decl.c (store_parm_decls): Among the old-style parm decls

||
there can legitiately be other decls! For example, if a parm
|
||
is declared `enum {foo, bar} x;', there are decls for `foo' and `bar'.
|
||
Don't let anything but a PARM_DECL match a parm name;
|
||
pass all the other decls through into the lexical context.
|
||
|
||
* jump.c (jump_optimize): When deleting stack adjusts before a
|
||
jump-to-return, don't be fooled by intervening NOTEs.

* tm-sequent.h (PRINT_OPERAND): Output (MEM (MEM (REG))) properly.
|
||
* output-ns32k.c (print_operand_address): Output (MEM (REG))

properly; output stack-pointer as `tos'.
|
||
|
||
* flow.c (find_use_as_address): Reject uses within operand 0
|
||
of a ZERO_EXTRACT or SIGN_EXTRACT reference. It's hard to reload
|
||
an autoincrement inside these because they can refer to multiple bytes.
|
||
|
||
* reload.c (find_reloads): `o' in constraint means any memref
|
||
(except auto-increment) is acceptable with reloading.
|
||
Braino: Clear BADOP, not BAD.
|
||
|
||
* reload.c (push_reloads): Use rtx_equal_p (via macro MATCHES)
|
||
when considering reuse of an old reload. Otherwise equal values
|
||
may get reloaded into different registers, and two MEMs that
|
||
originally matched may fail to match once reloaded.
|
||
|
||
* m68k.md (sign_extract and zero_extract insns):
|
||
If operand 0 is QI or HImode, don't allow register--only `o'
|
||
(except in some bftst patterns where bitpos is < 8).
|
||
And change `m' to `o' in all these patterns.

||
Sun Mar 27 15:32:54 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
|
||
|

|
||
|
||
* gcc.c: Pass -y* to ld.
|
||
|
||
* cse.c (struct hash): New member `equivalence_only'.
|

When finding cheapest equivalent of something,
|
||
skip elts that are marked with `equivalence_only'.
|
||
|
||
* decl.c (duplicate_decls): Don't call `layout_type'
|
||
if the type is `error_mark_node'.
|
||
|
||
* decl.c (implicitly_declare): If decl will be file-scope,
|
||
make sure it's a permanent node, and its associated data too.
|
||
|

|
||
|
||
* flow.c (insn_dead_p, mark_used_regs): Storing a reg via a

|
||
to the name of this function.
|
||
* tm-vms.h (MAYBE_VMS_FUNCTION_PROLOGUE): Use current_function_name.

|
||
Use `adjspw' when appropriate.
|

New pattern for `lprd' insn.
|

|
||
* expmed.c (extract_fixed_bit_field): In memory-word case, abort

||
if tm.h parms say word could fail to be well-aligned.
|
||
* tm-ns32k.h: Define STRUCTURE_SIZE_BOUNDARY so they will be aligned.

||
* tm-vax.h: Define STRUCTURE_SIZE_BOUNDARY since Unix CC seems to.

||
|
||
* stmt.c (assign_parms): Get size of BLKmode local from the type,
|
||
not the mode.
|
||
(expand_function_start): Init frame_offset before calling assign_parms.
|
||
|
||
Wed Mar 23 23:50:37 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
|
||
|
||
* expr.c (emit_push_insn): When making a move insn,
|
||
go via emit_move_insn; else fails to put constants into memory.
|
||
|

Tue Mar 22 15:45:10 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
|
||
|

actually call the predicate whatever it is.
|

* genemit.c (gen_expand): Make `operands' a local variable,
|

not a global static one, in the `gen_...' function.
|

Avoids lossage when one `gen_...' fcn calls another indirectly.
|
||
|
||
* genoutput.c (output_epilogue): Don't give printf a null string.
|

Force VALUE1, not VALUE, into a register.
|
||
|
||
* expmed.c (store_fixed_bit_field): Width of mask for clearing

* ns32k.md (branch and store-flag insns):
|
||
Test cc_prev_status, not cc_status.
|
||
|
||
* expmed.c (extract_bit_field): Delete unused var `omode'.

|
||
|
||
* tm-sun*.h: Don't predefine `m68k'; Sun's compiler does not.
|
||

|
||

|
||
|
||
* emit-rtl.c, tree.c: include local version of varargs.h.
|
||
|
||
* decl.c (start_function): Clear TREE_EXTERNAL and set TREE_STATIC
|
||
here rather than in finish_function. Affects the case of
|

`extern foo (); static foo (a) {...}'
|
||
|
||
* gcc.c: Handle -fnostdinc and -fnostdlib switches in specs.
|
||
|

|
||
on the chain to be searched.

|
||
Eliminate the code here to move a DImode or DFmode by pieces.

|
||
* emit-rtl.c (emit_insn): Return-value was wrong if emit_to_sequence;
|
||
cannot use `last_insn' in that case.
|
||
|
||
* regclass.c, stupid.c, local-alloc.c, global-alloc.c:
|
||
Some vars of type HARD_REG_SET should be `register' only
|
||
if HARD_REG_SET is a macro (ie a scalar).
|
||
|
||
* expr.c (move_block_from_reg): New function, converse of
|
||
move_block_from_reg.
|
||
* stmt.c (assign_parms): If a BLKmode arrives in regs,

* cse.c (fold_rtx): Don't fold if result is not LEGITIMATE_CONSTANT_P.
|
||
Construct all results in new local variable NEW; then test that

|
||
* cse.c (cse_insn): When SRC_EQV is non-0 but set[0] has been
|
||
cleared, don't insert SRC_EQV in hash table.
|
||
|
||
* All insns emitted by a define_expand become part of the SEQUENCE:
|
||
* SEQUENCE now contains a vector of insns, not of bodies.
|
||
* insn-emit.c (add_insn): If `emit_to_sequence' nonzero, add the
|
||
insn to a separate chain, `sequence_first_insn'.
|
||
(gen_sequence): Take everything on that chain and make a SEQUENCE.
|
||
(emit_insn): Handle SEQUENCE differently since elts are now insns.
|
||
(emit_insn_{before,after}): Handle SEQUENCE.
|
||
(classify_insn): #if 0.

Define two macros DONE and FAIL for use in a DEFINE_EXPAND:
|
||
Use DONE to inhibit emission of the pattern of the DEFINE_EXPAND.
|
||
Use FAIL to make the gen_... function return 0.
|
||
|
||
Mon Mar 14 12:47:28 1988 Richard Stallman (rms at wheaties.ai.mit.edu)
|
||
|
||
* expr.c (expand_expr): Extend the don't-sign-extend-enums hack
|
||
to COMPONENT_REF. (See 3 March.)
|
||
|
||
* tm-*.h (FUNCTION_ARG, etc.) New argument NAMED
|
||
is nonzero for a named arg, zero for an anonymous extra arg.
|
||
* expr.c (expand_call): Pass 1 for NAMED if appropriate.
|
||
* expr.c (emit_library_call): Pass 1 for NAMED.
|
||
* stmt.c (assign_parms): Pass 1 for NAMED.
|
||
|
||
* cccp.c: Test __GNUC__, not __GNU__.
|
||
|
||
* integrate.c (copy_and_substitute_rtx):
|
||
Replacing a MEM parm with the parm value, convert mode if mismatch.
|
||
Always use VOIDmode when generating SETs.
|
||
Take heed of FIRST_PARM_OFFSET and distinguish arg-pointer
|
||
from frame-pointer when they are different.
|
||
(expand_inline_function): Handle (RETURN) insns, by creating a
|
||
return_label which is output after the integrated code.
|
||
|
||
* parse.y (yylex): Condition for ignoring `inline' was backwards.
|
||
|
||
* flow.c (mark_used_regs): Ignore STRICT_LOW_PART, so that
|
||
an insn that sets STRICT_LOW_PART (and its source values) may be dead.
|
||
(propagate_block): Always pass 1 for strict_low_ok to insn_dead_p.
|
||
|
||
* optabs.c (emit_unop_insn): Don't make a REG_RETVAL note.
|
||
Change above deletes dead STRICT_LOW_PART stores without one.
|
||
|
||
* optabs.c (expand_binop, expand_unop): If the library address
|
||
is to be put in a pseudoreg, do it here, and make the REG_RETVAL
|
||
note point after that.
|
||
|
||
* expr.c (emit_library_call): Never defer stack-pops.
|
||
Deletion of the library call by flow.c loses if they are deferred.
|
||
|
||
* cse.c (cse_insn): Handling of 68k's zero-extend was broken:
|
||
it made the actual source and the REG_EQUAL source equivalent.
|
||
* If dest is a STRICT_LOW_PART, ignore the actual source and use
|
||
the REG_EQUAL source in its place. src_eqv's mode may be different
|
||
from src's, so use proper mode in lookups or inserts for src_eqv.
|
||
* Don't forget to set src_eqv_elt if src_eqv already has an elt.
|
||
* On use_related_value for src_eqv, use src_eqv_elt.
|
||
|
||
* toplev.c (main_input_filename): Name of file mentioned in first
|
||
#-line in the input.

|
||
arg is passed entirely in regs.
|
||
(emit_push_insn): Use move_block_to_reg when PARTIAL > 0.
|
||
Also, don't subtract USED from SIZE twice.
|
||
Use plus_constant to add ARGS_SO_FAR so can use indexing on stack ptr.
|
||
|
||
* varasm.c (assemble_integer_zero): Use rtx 0, not tree 0,
|
||
to go with prev change in ASM_OUTPUT_INT.

|
||
to access the word past the end of the existing object.

|
||
* gcc.c: If -O, define __OPTIMIZE__.

when appropriate whether or not it is the default.
|

|
||
|
||
* parse.y: Define YYDEBUG.
|
||
|
||
* rtl.c (rtx_unstable_p): New function, same as old rtx_varies_p.
|
||
* explow.c (stabilize): Use rtx_unstable_p.
|
||
* rtl.c (rtx_varies_p): Ignore `unchanging' (undoing previous change
|
||
in this function) because `unchanging' doesn't enable cse to compare
|
||
the value with any particular constant value.
|
||
* rtl.c (insn_store_addr_varies_p): Delete, since not used.
|
||
|
||
* hard-reg-set.h (COPY_HARD_REG_SET, etc.) non-scalar case:

Rename and rearrange temp variables to avoid name conflicts with args.
|
||
|
||
* regclass.c (reg_class_record): Don't smash class to GENERAL_REGS

||
* expr.c (expand_call) [no PUSH_ROUNDING]: When pushing the arg
|
||
block, try to reuse some of the pending_stack_adjust.
|
||
|
||
* cse.c: qty_const can now hold values (PLUS frame_pointer integer).
|
||
Effect is that storing into a structure doesn't invalidate
|
||
mem refs to scalar stack variables via addresses in registers.
|
||
(insert): Load such values into qty_const, like true constants.
|
||
(fold_rtx): Ignore qty_const if it isn't really a constant.
|
||
|
||
* expr.c (expand_expr) VAR_DECL: Copy DECL_RTL before calling

||
If it's a MEM in the stack, return a copy of it.
|
||
|
||
* stmt.c (fixup_stack_slots): #if 0.
|
||
* stmt.c (expand_finish_function): Don't call fixup_stack_slots
|
||
because fixup_stack_1 is called elsewhere when necessary.
|
||
|
||
* reload.c (find_reloads_address): New arg is location of the MEM
|
||
whose address is being reloaded. So we copy the MEM if it
|
||
is one that can be shared. New arg 0 means no need to copy the MEM.
|
||
All callers pass the new arg.
|
||
|
||
* stmt.c (assign_parms): Determine parm stack-size from
|
||
the DECL_ARG_TYPE, not from the TREE_TYPE.
|
||
Else loses when parm is declared `float' but passed as `double'.
|
||
|
||
* emit-rtl.c (make_safe_from): Constants are already safe.
|
||
Use proper machine mode for temp reg when needed.
|
||
|
||

|
||
|
||
* expr.c (emit_push_insn): Don't pass wrong type to plus_constant
|
||
(case where there is no PUSH_ROUNDING).
|
||
|
||
* expr.c (expand_call): Round partial[i] down to multiple of
|
||
PARM_BOUNDARY before subtracting it from arg size on stack.
|
||
Compute these sizes just once and keep them in vector `arg_size'.
|
||
* expr.c (emit_push_insn): Handle `partial' uniformly, in accord
|
||
with this new convention for how it affects the stack size.
|
||
* stmt.c (assign_parms): Round NREGS down to PARM_BOUNDARY likewise.
|
||
|
||
* obstack.h (obstack_free macro) [Not __GNUC__ but __STDC__]:
|
||
Don't cast result of (obstack_free) to (int); just ignore it.
|
||
|
||
* reload.c (find_reloads): Initialize operand_reloadnum.
|
||
|
||
* optabs.c (emit_unop_insn): New argument CODE, used to make
|
||
a REG_EQUAL note from operand OP0 if more than one insn results.
|
||
Also a REG_RETVAL note.
|
||
* expr.c (convert_move): Pass CODE arg to emit_unop_insn.
|
||
* flow.c (propagate_block): Use insn_dead_p to decide whether
|
||
to handle a REG_RETVAL note by skipping some insns.

||
Always pass 1 for STRICT_LOW_OK for an insn that has a REG_RETVAL note.
|
||
Handle case where REG_RETVAL points at an insn that's deleted.
|
||
* flow.c (insn_dead_p): New operand STRICT_LOW_OK says an insn
|
||
that sets STRICT_LOW_PART may be considered dead.
|

|
||
Change on March 1 made it stop doing this.

|
||
|
||
* loop.c (move_movables): Don't always mark the moved reg
|
||
as equivalent to a constant value: not if it is being cleared
|
||
to zero-extend something or if it is used outside the loop.
|
||
|
||
* expr.c (move_by_pieces_1): Finish last change.
|
||
|
||
* stmt.c (assign_parms): Update stack_args_size properly.

|
||
so that the oldest element in the chain is the one that follows
|
||
the most basic element.
|
||
|
||
* expr.c (expand_expr): COMPONENT_REF case: criterion for

|
||
|
||
* cse'ing of library calls.
|
||
|
||
* expr.h: type `optab' is now a ptr to a struct.
|
||
The old contents are now the `handlers' element.
|
||
The `code' element gives the RTL code for the kind of expression
|
||
this optab makes (PLUS for add_optab, etc.)
|
||
Every var formerly declared `struct optab *' is now just `optab'.
|
||
|
||
* optabs.c (init_optab, init_optabs): New function to init an optab

* optabs.c (expand_binop, expand_unop): Use the `code' field
|
||
to add a REG_EQUAL note to the insn that copies a libcall's

first insn for setting up args for the call.
|
||
|

|
||

|
||
|
||
* varasm.c (init_const_rtx_hash_table): Initialize constant pool
|
||
for a new function. Called from `expand_function_start'.

|
||
|
||
* reload.c (push_reloads): If IN occurs within OUT,

|
||
|
||
* reload1.c (choose_reload_targets): Don't choose an inherited

||
(for a MEM, the address must be invariant).

||
* genconfig.c (walk_insn_part): DO consider MATCH_DUPs
|
||
when calculating MAX_RECOG_OPERANDS.
|
||
(gen_expand): define_expand is now different from define_insn.

||
Compute max # SETs or CLOBBERs for any one sub-insn in a define_expand,
|
||
instead of summing them all. And don't count the MATCH_DUPs at all.
|

* genemit.c (max_operand_1): Record largest opno in a MATCH_DUP
|
||
separately from largest in a MATCH_OPERAND.

|
||
|
||
When an arg is split between regs and stack, make stack space
|
||
for the rest of it, and count it.
|
||
In a varargs function, push the last arg onto the stack.

* stmt.c (expand_function_end): fixup_gotos needs 2 args.
|
||
|

reasons.
|
||
* expr.c (convert_move): Use emit_unop_insn for outputting the
|
||
conversion insns.
|
||
|

|
||
|
||
* reload1.c (reload): At end, clobber a pseudoreg to a MEM
|
||
even if it's an out-of-range address. It doesn't affect the

assembler code in this case, but it makes the dbx output correct.
|
||
|
||
* recog.c (constrain_operands): When operands_match_p returns 2,
|
||
in the constraint alternative that is ultimately successful,
|
||

||
group, or else one that has only one available neighbor.
|
||
|
||
* reload1.c (reload): Find separately the max need for each class
|
||
for single registers, groups of registers, and single registers
|
||
not in any group. (The last one counts non-group reloads
|

in insns that have at least one group reload.)
|
||
Then make sure enough of each kind are found.

|
||
data type of function.

||
Rename the `delete' function as `delete_macro'
|
||
to avoid VMS name conflict.

* cexp.y: Treat $ as an identifier-character if DOLLARS_IN_IDENTIFIERS.
|
||
|
||

only within a word, not for DImode vs SImode.
|
||
|
||

|
||
from its own stack slot; delete it instead.

|
||
|
||
* reload1.c (choose_reload_targets): If a mode doesn't fit the
|
||
reload register, and the insn is an ASM_OPERANDS, ignore the reload.
|
||
Otherwise, final would crash.
|
||
|
||
* expmed.c (expand_shift): Two new strategies for lshr on short/char:
|
||
widen and do ashr, or widen and do extzv.
|
||
|
||
* vax.md (peepholes): Use dead_or_set_p to check for eliminable
|
||
intermediate result, rather than requiring a match with final result.
|
||
|
||
* local-alloc.c (block_alloc): Testing frame_pointer_needed is
|
||
enough; no need to test FRAME_POINTER_REQUIRED, etc.
|

|
||
* reload1.c (reload): Likewise for flag_omit_frame_pointer
|
||

|
||
|
||
* reload1.c (reload): Initialize `regmask' to zero.
|
||
Class number is in I, not in CLASS, when setting its elements.
|
||
Don't let J+K be too large.
|
||
|
||
* reload1.c (potential_reload_regs): Make it a `short'
|
||
since that can't be unsigned.
|
||
|
||
* cccp.c (warning): New function, called like `error'.

||
* cccp.c (do_define): Make redefinition just a warning.
|

|
||
|
||
* expmed.c (store_fixed_bit_field): Don't try gen_lowpart on VALUE

|
||
* expr.c (emit_block_move, emit_push_insn, clear_storage):

If TARGET_MEM_FUNCTIONS, generate calls to memcpy and memset
|
||
instead of bcopy and bzero.
|
||
* optabs.c (emit_cmp_insn): Likewise for memcmp vs bcmp.
|
||
|
||
* stmt.c (expand_goto): New temp var to avoid RT/PC compiler bug.
|
||
|
||
Sun Feb 7 12:20:23 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* flow.c (mark_used_regs, mark_set_regs):
|
||
Handle hard regs in multiword modes: set the bits for each
|
||
distinct register-number that makes up the multiword mode.
|
||
Necessary because function arg registers can inevitably
|
||
live across basic blocks.
|
||
|
||
* cse.c (canon_hash): Function arg and value registers no longer
|
||
considered volatile, because flow should now handle the code that
|
||
can result from cse'ing them.
|
||
|
||
* cse.c (make_regs_eqv): Abort if OLD is invalid.
|
||
* cse.c (reg_invalidate): Abort if reg already invalid has eqvs.

|
||
|
||
* expmed.c (extract_fixed_bit_field):
|
||
Must always generate an `and' to mask the bitfield
|
||
unless its width is the same as the output machine mode.
|
||
|
||
* version 1.18 released.
|
||
|

|
||
Mon Feb 1 18:53:05 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)

|
||
is now register_operand.
|
||
|
||
* stdarg.h: Make va_list be char *, not char *[1].
|
||
Latest draft doesn't say it must be an array type.
|
||

Sun Jan 31 11:14:07 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|

|
||
compiler bug.
|
||
|
||
* tm-ns32k.h (GO_IF_LEGITIMATE_ADDRESS): Don't allow pushes or pops
|

since there are special insn patterns for them.
|
||
Resubroutinize and add temp vars to make expressions smaller.
|
||
* ns32k.md: Add a few more special stack insns; now there are enough.
|
||
|
||
* tm-sequent.h: Definitions of DBX_NO_XREFS and DBX_CONTIN_LENGTH.
|
||
|
||
* reload1.c (choose_reload_targets): Handling of reload_strict_low
|
||
is needed for input reloads as well as output, since a strict_low_part
|
||
operand is normally a read-write operand.
|
||
|
||
* reload1.c (reload): The mode a reload needs is the wider of
|
||
the input and output modes--just as it is in choose_reload_targets.
|
||
|
||
* reload.c (find_dummy_reload): If IN and OUT have different widths
|
||
and one of them exceeds a word, don't find any dummy reload.
|
||
|
||
* toplev.c (compile_file): Allocate enough space for .jump2 filename.
|
||
|
||
Sat Jan 30 10:35:46 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* output-ns32k.c (print_operand_address):
|
||
Print addresses of the form C1+(N*REG+C2) which currently
|
||
are accepted as legitimate memory addresses.
|
||
|
||
* tm-sequent.h: Simple bugs in PRINT_OPERAND, TARGET_DEFAULT
|
||
and SEQUENT_ADDRESS_BUG.
|
||
|
||
* gen*.c: Must explicitly exit; returning from `main' fails
|
||
to indicate nonzero status due to bug in Unix.
|
||
|
||
* parse.y (check_line_number): Ignore entire line of unrecognized
|
||
#-directive; no error if it is `pragma'.
|

|
||
|
||
* reload1.c (reload): Make basic_block_needs 0 until after the
|
||
frame pointer reg is spilled, so that ALL pseudos in it are spilled.
|
||
|
||
* typecheck.c (truthvalue_conversion):
|
||
Strip a NOP_EXPR only if it extends, not if it truncates.
|
||
(build_unary_op): For TRUTH_NOT_EXPR, call invert_truthvalue
|
||
to simplify.
|
||
|
||
* Fixes for HPUX support from cph:
|
||
* tm-hp9k320.h: Correct names of floating-point registers.
|
||
Fix typos in ASM_OUTPUT_OPCODE; also convert `fmove' to `fmov'.
|
||
* Makefile (comments for HPUX):
|
||
cph says -Wd,-X isn't needed in CFLAGS, nor -lBSD in CLIB.
|
||
Also that -g can't be used in CFLAGS with HP's pcc.
|
||
* conf-hp9k320.h: New file, like config-m68k.h but with
|
||
#defines for the bstring functions.
|
||
* m68k.md: Add else-clauses to the HPUX_ASM conditionals on cmp insns.
|

Thu Jan 28 09:51:41 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|

* jump.c (jump_back_p): If TARGET is unconditional, return 0.
|
||
|
||
Wed Jan 27 04:18:29 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* combine.c (subst): Simplify (plus (plus x c1) c2).
|
||
|
||
* expr.c (emit_push_insn): Don't use small-block push-insns for BLKmode
|
||
when one of them would be affected by PUSH_ROUNDING.
|
||
Instead, make all the space and then copy.
|
||
* expr.c (expand_call): Don't apply PUSH_ROUNDING if BLKmode.
|
||
|
||
* Allow `asm' with operands to be marked volatile.
|
||
* cse.c (canon_hash): Don't record ASM_OPERANDS that has `volatil'.
|
||
* loop.c (invariant_p): ASM_OPERANDS with `volatil' can't be invariant.
|
||
* flow.c (volatile_refs_p): Note ASM_OPERANDS that are volatile.
|
||
* stmt.c (expand_asm_operands): New arg VOL; mark ASM_OPERANDS as vol.
|
||
* typecheck.c (c_expand_asm_operands): New arg VOL.
|
||
* parse.y: allow a TYPE_QUAL after ASM.
|
||
|
||
* Make cse handle `asm' with operands:
|
||
* cse.c (canon_hash): Hash string operands by contents, not address.
|
||
* cse.c (exp_equiv_p): Compare string operands with strcmp.
|
||
* rtl.c (rtx_equal_p): Compare string operands with strcmp.

|
||
correct the type of the sizes of types already made.
|
||
|

* cccp.c (do_defines): Don't reject #define foo{a}.
|
||
|
||
Tue Jan 26 04:53:16 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* reload.c (find_reloads): Now that `asm' is limited to
|
||
MAX_RECOG_OPERANDS, eliminate dynamic allocation of `constraints'
|
||
and `constraints1', and go back to `recog_operand' instead of
|
||
`operands'.
|
||
|
||
* typecheck.c (c_expand_asm_operands): New fn to handle `asm' for C.
|
||
Calls expand_asm_operands, and handles output operands that
|
||
the other function cannot handle.
|
||
|
||
* parse.y: Call that function.
|
||
|
||
* stmt.c (expand_asm_operands): Error if too many operands.
|
||
#include insn-config.h to get MAX_RECOG_OPERANDS.
|
||
|
||
* expr.c (expand_assignment): Use store_field to handle
|
||
structure fields and array elements.
|
||
|
||
* output-m68k.c (output_move_double): PUSHOP and POPOP were swapped.
|
||
Handle insns that push an sp-relative address onto sp;
|
||
these can arise with -fomit-frame-pointer.
|
||
BUG? Do unoffsetable mem refs using sp and fp lose?
|
||
|
||
* m68k.md (movdi,movdf): Allow unoffsetable mem refs
|
||
only if the other operand is a register.
|
||
|
||
* m68k.md (zero_extendqisi2): SGS conditionals deleted.
|
||
Supposedly the MOTOROLA syntax works for those addresses.
|
||
|
||
* typecheck.c (default_conversion):
|
||
If flag_traditional, preserve unsignedness when promoting ints,
|
||
and promote float to double.
|
||
|
||
* typecheck.c (build_binary_op_nodefault):
|
||
Allow comparisons between pointers and ints.
|
||
If not -traditional, warn about them.
|
||
|
||
Mon Jan 25 02:11:18 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* expmed.c ({extract,store}_split_bit_field):
|
||
Functions {extract,store}_split_reg_bit_field now work for memory
|
||
also, and therefore are renamed.
|
||
* ({extract,store}_fixed_bit_field): Call those fns when a field
|
||
is split across two words.
|
||
Also, preserve the `volatil' bit on memory refs.
|
||
|
||
* output-m68k.c (output_move_double): Handle nonoffsetable mem refs.
|
||
* m68k.md: Relax constraints on movdi, movdf.
|
||
|
||
* decl.c (init_decl_processing): Define `int' and `char' first.
|
||
Set `sizetype' explicitly.
|
||
|
||
* stmt.c (fixup_var_refs_1): May not just return when a SET
|
||
doesn't have VAR as its src or dest.
|
||
|
||
* varasm.c: Don't include c-tree.h.
|
||
|
||
* decl.c (build_struct): Split this function into three:
|
||
`xref_tag', `start_struct' and `finish_struct'.
|
||
`xref_tag' subsumes `xref_enum'.
|
||
|
||
* parse.y (structsp): When parsing `struct foo {...}', define the tag
|
||
as a cross-ref before parsing the components. Use the three new fns.
|
||
|
||
* regclass.c (regclass): Recognize new-format ASM_OPERANDS insns
|
||
with `asm_noperands', and scan their operands as usual.
|
||
|
||
* cse.c: In numerous functions such as canon_hash, rtx_cost, etc.
|
||
that do tree-walk on rtx, handle vectors of subexpressions.
|
||
|
||
* loop.c (invariant_p): Likewise.
|
||
|
||
* jump.c (delete_insn): Two bugs:
|
||
If insn already deleted, return the first following nondeleted.
|
||
Deleting a jump's label can delete NEXT. Make sure return value
|
||
is always the first insn following INSN and not yet deleted.
|
||
|
||
Sun Jan 24 02:27:49 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* rtl.def (ASM_OPERANDS): Change the rtl expression of an
|
||
`asm' with operands so it looks like this for one output operand:
|
||
(set OUTPUT (asm_operands:OUTPUTMODE INSNSTRING OUTPUTCONSTRAINT
|
||
0 INPUTS INPUTCONSTRAINTS)).
|
||
and like this for multiple outputs:
|
||
(PARALLEL [
|
||
(set OUTPUT0 (asm_operands:OUTPUTMODE INSNSTRING OUTPUTCONSTRAINT
|
||
0 INPUTS INPUTCONSTRAINTS)).
|
||
(set OUTPUT1 (asm_operands:OUTPUTMODE1 INSNSTRING OUTPUTCONSTRAINT1
|
||
1 INPUTS INPUTCONSTRAINTS))])
|
||
|
||
* parse.y: Change parsing of `asm' to distinguish input and output
|
||
operands. Separate them with colon; separate the string with colon.
|
||
|
||
* stmt.c (expand_asm_operands): Receive inputs and outputs separately.
|
||
Generate the new rtl format.
|
||
|
||
* recog.c (asm_noperands, decode_asm_operands): New fns
|
||
for extracting the operands and constraints from these insns.
|
||
|
||
* final.c (final): Recognize and output the new rtl format
|
||
using those new functions.
|
||
|
||
* reload.c (find_reloads): Recognize and get constraints
|
||
from the new rtl format using those new functions.
|
||
New variable `operand_modes' holds the machine modes of the
|
||
operands, obtained one way for ASM_OPERANDS insns and another
|
||
for other insns.
|
||
|
||
* rtl.c (note_stores): Calling convention
|
||
is changed: the first arg FUNCTION now receives as its 2nd arg
|
||
1 if clobbering, 0 if setting. Used to be the CLOBBER or SET rtx.
|
||
|
||
* local-alloc.c (reg_is_set): This fn is called from note_stores;
|
||
change its arguments.
|
||
|
||
* tm-m68k.h (FIXUP_FRAME_POINTER_ADDRESSES):
|
||
Use frame_pointer_rtx to recognize intended frame-pointer refs
|
||
and not recognize pseudo-regs that were allocated to the frame
|
||
pointer register.
|
||
|
||
* emit-rtl.c: All refs to frame pointer use a single rtx, in
|
||
frame_pointer_rtx. Likewise arg_pointer_rtx for the arg pointer.
|
||
If they are the same register, these are the same rtx.
|
||
Initialize them in init_emit.
|
||
* rtl.h: Declare these vars.
|
||
|
||
* stmt.c (assign_parms, assign_stack_local): Use those rtx's.
|
||
|
||
Sat Jan 23 00:32:10 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
|
||
|
||
* reload.c (find_reloads): Don't combine_reloads if `&' constraint
|
||
was used.
|
||
|
||
* parse.y: Parse `asm' with operands.
|
||
* stmt.c (expand_asm_params): New fn: generate an ASM_OPERANDS for
|
||
`asm' with operands.
|
||
* final.c (final): Output an ASM_OPERANDS insn-body.
|
||
* regclass.c (regclass): Ignore ASM_OPERANDS, like ASM_INPUT.
|
||
|
||
* reload.c (find_reloads): Handle reloading of ASM_OPERANDS.
|
||
The number of operands can no longer be bounded.
|
||
For example we can't always put the operands in recog_operands.
|
||
|
||
New locals OPERANDS and OPERAND_LOCS point to alloca'd vectors of
|
||
operands and their locations. New locals CONSTRAINTS and CONSTRAINTS1
|
||
hold alloca'd vectors of constraints.
|
||
|
||
Unfortunately this isn't enough; every vector with length
|
||
MAX_RECOG_OPERANDS needs to be dynamically allocated.
|
||
Would this be too slow? For now, a cheap "solution" is to delete
|
||
any insn that has too many operands.
|
||
|
||
* rtl.def: Delete VOLATILE, UNCHANGING and UNDESCRIBED.
|
||
Add ASM_OPERANDS.
|
||
|
||
* regclass.c (reg_class_record): Delete ref to UNCHANGING.
|
||
* loop.c (invariant_p):
|
||
* rtl.c (rtx_varies_p):
|
||
|
||
* cccp.c: Define __VERSION__.
|
||
|
||
* decl.c (shadow_tag): TYPE_NAME doesn't work to get the tag-name
|
||
of a struct, so use new function lookup_tag_reverse.
|
||
* decl.c (lookup_tag_reverse): Given a type, return its tag name.
|
||
|
||
* symout.c (symout_source_file): Output one `struct source'.
|
||
* symout.c (symout_lines): Output all of them, and the sourcevector.
|
||
* gdbfiles.h: New file for communication between final.c and symout.c.
|
||
|
||
* final.c (output_source_line): New arg WRITE_SYMBOLS says write
|
||
new GDB-format linenumber info. Assigns a filenum to each source
|
||
file name and keeps track of the correspondence.
|
||
|
||
* cccp.c (do_include): Output the -M info after searching the dirs;
|
||
include the actual dir name. Don't generate "./" for current dir.
|
||
|
||
Fri Jan 22 04:10:10 1988 Richard Stallman (rms at frosted-flakes)
|
||
|
||
* tm-news800.h: Delete override of INDIRECTABLE_1_ADDRESS.
|
||
Output is faster if it doesn't use 32-bit displacements.
|
||
|
||
* reload.c (combine_reloads): New function.
|
||
If possible, find an input reload
|
||
and an output reload that can be turned into one input-output reload.
|
||
The old output-reload is marked as inoperative: reload_out
|
||
and reload_in both zero. This is called from find_reloads.

|
||
* reload1.c (reload, choose_reload_targets): Ignore inoperative
|
||
reloads.
|
||
|
||
* Print warnings for variables that could be clobbered by `longjmp'.
|
||
* expr.c (expand_call): Generate a NOTE_INSN_SETJMP whenever
|
||
`setjmp' or `_setjmp' is called.
|
||
* flow.c (propagate_block): When NOTE_INSN_SETJMP is seen,
|
||
record the live regs in `regs_live_at_setjmp'.
|
||
* stmt.c (uninitialized_vars_warning): Warn about vars that have regs
|
||
that are set more than once and are marked in `regs_live_at_setjmp'.

|
||
|
||
* tm-ns32k.h: Use Stein's definitions of PRINT_OPERAND{,_ADDRESS};

|
||
Define CPP_PREDEFINES.
|
||
|
||
* ns32k.md: Merge some features from Jan Stein's port:
|
||
strict_low_part insns, smart output of booleans with small
|
||
constant args, acbd insns generalized for other increments.
|
||
Use %$ wherever there is an explicit immediate.
|
||
Fix shortcomings of adjsp insns: use adjspd in general,
|
||
and use adjspb in all the cases that allow it.
|
||
Don't bother explicitly clearing CC_REVERSED.
|
||
For tstsf/tstdf, output the floating-zero constants
|
||
using {f,d}const0_rtx.
|
||
|
||
A problem still remains, which is that the Sequent and the
|
||
other ns32k assembler syntax require different
|
||
|
||
* typecheck.c (unary_complex_value): Use correct datatype for
|
||
compound-exprs.

|
||
|
||
* tm-m68k.h: Bugs for 68000 when frame size is over 64k.
|
||
For FUNCTION_PROLOGUE, just subtract from sp instead of fp.
|
||
For FUNCTION_EPILOGUE, must put the size into a0 and then
|
||
all insns must be indexed by a0. And do this even on 68020.
|
||
|
||
* tm-isi68.h: Similar changes.
|
||
* tm-news800.h, tm-hp9k320.h: Similar changes.

* cccp.c (error_with_line): New function.
|
||
Use it to report the "unterminated whatever" errors.
|
||
|
||
* typecheck.c (build_unary_op): Recursive call had missing arg.
|
||
|
||
* m68k.md (movhi): If MOTOROLA, the insn that fetches from a
|
||
case-dispatch table now defines the LI label as .+2.
|
||
* tm-news800.el, tm-hp9k320.h (PRINT_OPERAND_ADDRESS):
|
||
Don't subtract 2 when outputting the address in that insn.

|
||
|
||
* stmt.c (fixup_memory_subreg): Convert (SUBREG (MEM a)) to (MEM a').
|
||
* stmt.c (fixup_var_ref_1): Use that fn for operands of
|
||
SIGN_EXTRACT and ZERO_EXTRACT, since (SUBREG:SI (REG:QI...))
|
||
could have turned into (SUBREG:SI (MEM:QI...)), which is unsafe.
|
||
|
||
* rtl.c (debug_rtx): Print an rtx on stderr, for debugging.
|
||
|
||
Sun Jan 17 04:37:20 1988 Richard Stallman (rms at frosted-flakes)

||
Sat Jan 16 02:10:22 1988 Richard Stallman (rms at frosted-flakes)
|
||
|
||
* ns32k.md: Change register_operand to general_operand.

||
Fri Jan 15 00:02:35 1988 Richard Stallman (rms at frosted-flakes)
|
||
|
||

|
||
* tm-hp9k320.h (ASM_OUTPUT_OPCODE): Convert `ftst' to `ftest'.

||
* tm-hp9k320.h: Define ASM_OUTPUT_SOURCE_{FILENAME,LINE}.

|
||
* m68k.md: Reverse `fcmp' args if HPUX_ASM.
|
||
|
||
* cccp.c (print_deps): 2 means give all files, 1 means only user files.
|
||
* cccp.c (do_include): Support that.
|
||
* cccp.c (main): -MM sets 1, -M alone sets 2.
|
||
* cccp.c (main): Give fatal error if I/O error in writing.
|
||
|
||
* toplev.c (fatal_io_error): Report I/O error on given filename,
|
||
and exit.
|
||
|
||
* toplev.c (compile_file): Detect error writing asm_out_file.
|

in a PARALLEL is not a SET.
|
||
|
||
* tm-m68k.h, tm-news800.h (PRINT_OPERAND). Eliminate code `%e'.
|
||
* m68k.md: Change `%e' to `e' everywhere.
|
||
* tm-hpux.h (ASM_OUTPUT_OPCODE): Output `move' as `mov'.
|
||
|
||
* tm-m68k.h, tm-news800.h, tm-hpux.h (PRINT_OPERAND):
|
||
New code `%!' is output as the name for the cc register.
|
||
* m68k.md (insns that use andi to ccr): Use `%!' to avoid
|
||
conditionals.
|
||
|
||
* cse.c: Record in qty_const_insn the insn that stored the
|
||
constant value of a qty. When making a REG_WAS_0 note,
|
||
store in it the insn that established the value 0.
|
||
|
||
* vax.md (movsi): When checking a REG_WAS_0 note,
|
||
verify that the insn it points to hasn't been deleted or made a NOTE.
|

Thu Jan 14 00:01:35 1988 Richard Stallman (rms at frosted-flakes)
|
||
|
||
* toplev.c: Eliminate error_with_line and warning_with_line.
|
||
* parse.y, decl.c: Change remaining calls to those two.
|
||

|
||

|
||
|
||
* rtl.c (print_rtx): Print /v for the `volatil' bit.
|
||
* expr.c (expand_assignment expand_expr): If handling a COMPONENT_REF,
|
||
note whether it is volatile.
|
||
|
||
* fold-const.c (fold): a call to split_tree missed an argument.
|
||
|
||
* flow.c (volatile_refs_p): Scan an rtx for volatile mem refs.
|
||
* flow.c (life_analysis): Record in INSN_VOLATILE which insns
|
||
have any volatile mem refs.
|
||
* flow.c (mark_used_regs): Always mark an insn with volatile mem refs.
|
||
Always pass INSN as an arg. New arg FINAL now says whether

this is the last time scanning.
|
||
* flow.c (propagate_block): Don't delete insns with volatile mem refs.
|
||
|
||
* flow.c: Remove all refs to `obey_regdecls'.
|
||
Calling this with -noreg just doesn't help -W.
|
||
|
||
Wed Jan 13 01:13:07 1988 Richard Stallman (rms at frosted-flakes)
|
||
|
||
* decl.c (finish_decl): Error if auto var's size isn't known.
|
||
Change type to error_mark_node to avoid crash if the var

|
||
for FUNCTION_DECL or TYPE_DECL.
|
||
|
||
* toplev.c (warning_with_decl): New warning function with decl as arg.
|
||
* (error_with_decl): similar.
|
||
|
||
* decl.c: Replace most `yylinerror' calls with `error_with_decl'.
|
||
|
||
* decl.c (build_struct): Reform code to detect erroneous bit-fields.
|
||
All such errors are now detected here.
|
||
Promote bit-fields to int if appropriate.
|
||
If traditional, make all int bit-fields unsigned.
|
||
Set DECL_ALIGN for members that are not bit-fields.
|
||
|
||
* decl.c (grokfield): Don't set DECL_ALIGN here.
|
||
|
||
* stor-layout.c (layout_decl): Don't promote the type of a bit-field.
|
||
Use TREE_PACKED to distinguish a bit-field.
|
||
Don't check the width because build_struct did that.
|
||
|
||
* m68k.md (cmpm): Reject if either operand (address) is a constant.
|
||
|
||
Tue Jan 12 15:11:20 1988 Richard Stallman (rms at frosted-flakes)
|

|
||
|
||
Mon Jan 11 13:15:45 1988 Richard Stallman (rms at frosted-flakes)

||
|
||
Sun Jan 10 14:52:42 1988 Richard Stallman (rms at frosted-flakes)
|
||
|
||
* reload1.c (reload): basic_block_needs (new vector) gets 1
|
||
for each basic block that needs a reload.
|
||
* reload1.c (spill_hard_reg): Don't spill pseudos that are
|
||
confined to a basic block which has no need for any reloads.
|
||
* reload1.c (reload): Each cycle that any element of basic_block_needs
|
||
changes from 0 to 1, must re-spill all previously spilled regs.
|
||
|
||
* regclass.c (record_address_regs):
|
||
Skip the charging of ICOST if it is 0.
|
||
|
||
* flags.h, toplev.c: New flag -fvolatile.
|
||
* typecheck.c (build_indirect_ref): If flag_volatile,
|
||
every INDIRECT_REF is marked with TREE_THIS_VOLATILE.
|
||
|
||
* fold-const.c (fold): Test in TRUTH_NOT_EXPR case was backward.
|
||
Also result type is always `int'.
|
||
|
||
Sat Jan 9 04:16:11 1988 Richard Stallman (rms at rice-krispies)
|
||
|
||
* flags.h (flag_traditional): New flag.
|
||
* toplev.c: recognize -ftraditional and -traditional.
|
||
* parse.y (yylex): If flag_traditional, don't recognize
|
||
`signed', `const' or `volatile'.
|
||
|
||
* decl.c (pushdecl): If flag_traditional, any extern decl
|
||
takes effect at top level.
|
||
|
||
* tree.c (lvalue_or_else): New 2nd arg for use in error message.
|
||
* typecheck.c: All callers pass 2nd arg.
|
||
|
||
* global-alloc.c: allocno_preferred_reg can specify a preferred
|
||
hard reg for each allocno. If so, try it first (new call to find_reg).
|
||
|
||
* global-alloc.c (find_reg): New arg PREFREG specifies reg to try
|
||
first.
|
||
|
||
* decl.c (build_struct): if :0 bit field at the end, round the
|
||
structure size to multiple of EMPTY_FIELD_BOUNDARY.
|
||
|
||
* cse.c (make_regs_eqv): Was testing for reg_next_eqv[lastr] == 0
|
||
and should be == -1.
|
||
|
||
* reload1.c (reload_as_needed): Fix invalid optimization deleting
|
||
the previous store into a pseudo-reg that feeds an input-reload.
|
||
It is not safe because a later insn may look in the pseudo's stack
|
||
slot for the value. Delete the store only if we can eliminate the
|
||
pseudo entirely or if the current insn stores a new value there.
|
||
Also verify that reload_in[j] is a REG.
|
||
|
||
* reload1.c (reload_as_needed): When doing an input reload from a
|
||
pseudo that was stored by the previous insn (not as a reload),
|
||
redirect the previous insn into the reload register, if this lets
|
||
us eliminate the pseudo entirely.
|
||
|
||
* reload1.c (reload_as_needed): In both of the above cases, it's
|
||
impossible to prevent a stack slot since one was already assigned,
|
||
so don't alter reg_n_refs. Instead, set reg_renumber to record
|
||
that this pseudo did get a hard reg.
|
||
|
||
* stmt.c: Set `volatil' in pseudo-regs for the user's variables.
|
||
|
||
* jump.c (delete_insn): Do nothing if insn already deleted.
|
||
|
||
* tm-sun{2,3}.h: #define STRUCTURE_SIZE_BOUNDARY 2
|
||
for compatibility with Sun PCC. Note that 4.3 vax PCC
|
||
does not want this.
|
||
|
||
* fold-const.c: Replace truncate_unsigned with force_fit_type
|
||
which truncates unsigned types and sign-extends signed types.
|
||
|
||
* expr.c (do_jump): emit_queue before outputting the jump insns
|
||
that use the comparison.
|
||
|
||
* stmt.c: Error message for any goto that jumps into a
|
||
binding contour that restores a stack level.
|
||
|
||
TREE_PACKED (label) means label was defined inside
|
||
such a binding contour that is now exited. Using such a label
|
||
is an error.
|
||
|
||
TREE_ADDRESSABLE (label) means label was used from a place
|
||
outside all such binding contours. If this is 1 when
|
||
TREE_PACKED is set to 1, it is an error.
|
||
|
||
Any other invalid goto must have a fixup. fixup_gotos detects
|
||
such invalid gotos. fixup_gotos takes a second arg, which
|
||
is the first insn of the contour now being exited.
