Fri May 7 04:48:25 1993 Chris Smith (csmith@convex.com)
* x-convex (CCLIBFLAGS): Build libgcc1 with -tm c1 so it can't
cause executables to become c2-only.
* xm-convex.h: Remove workarounds for OS 8.0 no longer needed.
(bcopy, bzero): Define to use memcpy and memset, to get them inlined.
* convex[123*].h (CC1_SPEC, CPP_SPEC, LIB_SPEC): Move to convex.h.
* convex.h (TARGET_FLAGS): Add -mvolatile-[no]cache.
(TARGET_FLAGS, LONG_TYPE_SIZE): add -mlong{32,64}.
(target_cpu): Define, enumeration for targets to use instead of flags.
(TARGET_C34, TARGET_C38): Add. These don't schedule the same as C2.
(OVERRIDE_OPTIONS): Call init routine in convex.c.
(CPP_SPEC, ASM_SPEC, LINK_SPEC): If originally bootstrapped with
an ieee compiler, produce an ieee gcc.
(LINK_LIBGCC_SPECIAL): Define, to avoid searching old libgcc.a
versions during bootstrap.
(STACK_BOUNDARY): Change from 32 to 64 -- odd-word aligned
longwords are slow on c34.
(FUNCTION_PROLOGUE): Make frame size a multiple of 8, not 4.
(FUNCTION_EPILOGUE): Output a 0 to terminate c34 icache prefetch.
(INITIAL_FRAME_POINTER_OFFSET): Make a multiple of 8.
(REG_ALLOC_ORDER): Define. Put S0 (the return register) last.
(HARD_REGNO_MODE_OK): Rewrite to make clearer.
(MODES_TIEABLE_P): Rewrite to make clearer.
(PREFERRED_RELOAD_CLASS): Rewrite to make clearer.
(S0_REGNUM, A0_REGNUM): Define.
(*_REGNUM): Write in terms of [AS]0_REGNUM instead of absolute numbers.
(enum reg_class, etc): Add SI_REGS == S_REGS + INDEX_REGS.
(REGNO_REG_CLASS, REG_CLASS_FROM_LETTER, REGNO_OK_FOR_*_P): Use tables.
(CONST_OK_FOR_LETTER_P): Change. New def passes any const_int,
rejects any const_double.
(CONST_DOUBLE_OK_FOR_LETTER_P): Change. New defs are 'G' == low
word all zeros, 'H' == high word all signs.
(EXTRA_CONSTRAINT): New. 'Q' == volatile memref. Used to generate
cache-bypass instructions when -mvolatile-nocache is set.
(RETURN_POPS_ARGS): Change, always true.
(FUNCTION_ARG_ADVANCE): Count args, not # words of args.
(FUNCTION_ARG): Return arg count to the final VOIDmode FUNCTION_ARG
hack that supplies "next arg register" to be stored in call insn.
(TRAMPOLINE_TEMPLATE): Use instruction notation rather than constants.
(INITIALIZE_TRAMPOLINE): Use gen_call_pop.
(LEGITIMATE_CONSTANT_P): Rewrite to make clearer.
(GO_IF_LEGITIMATE_ADDRESS): Do not use indirect addressing -- with
insn scheduling, two loads can be faster and can't be slower.
(SLOW_BYTE_ACCESS): Define unless C2. Memory access to bytes is
not actually slow, but faster processors don't forward partial
word writes to word reads, and setting SLOW_BYTE_ACCESS
makes the code consistently use word ops where possible.
(CONST_COSTS): Const_DOUBLE cost is zero -- if it appears, it is
immediate and therefore free.
(RTX_COSTS): areg+const is free (via indexing).
(RTX_COSTS): Provide target-dependent values for *,<<,>>
(ADDRESS_COST): Zero. Indirect addresses are no longer used.
(ADJUST_COST): Define.
(TARGET_FLOAT_FORMAT): Define as VAX_FLOAT_FORMAT. Also
accurately describes the semantics (not the bit pattern)
of convex ieee mode.
(REAL_VALUE_ATOF): Define, to prevent real.c from constructing
vax dfloats. Apparently it doesn't do gfloat.
(CHECK_FLOAT_VALUE): Call convex.c.
(ASM_FILE_START): Output appropriate .fpmode pseudo op.
(ASM_IDENTIFY_GCC): Ouput a zero after gcc2_compiled to keep it
from hiding the real name from profilers and adb.
(ASM_OUTPUT_DOUBLE, _FLOAT): Use hex to avoid /bin/as conversion
errors.
(ASM_DECLARE_FUNCTION_NAME): Define; call convex.c.
(PRINT_OPERAND, _ADDRESS): Call convex.c.
(EXIT_BODY): Define for libgcc2. Call atexit handler if present.
convex.md: Add scheduling info.
(movxx): One of the operands must be a register.
(movdf, movdi): Add anonymous patterns that can load an arbitrary
const_double by doing two immediate loads. This is not superior
to loading it from memory, and can be worse, so LEGITIMATE_CONSTANT_P
still rejects these constants, but the patterns are still useful
so rtx folding can produce arbitrary results.
(floatunsdidf, floatunsdisf): Add patterns that avoid double rounding.
(floatunssidf, floatunssisf): Add patterns that mimic gcc's default
method, to keep SI cvts from promoting to the above DI cvts.
(fix_truncdfsi2): Use cvtd.l even if cvtd.w is available -- on c34
cvtd.w is microcoded and slower.
(addqi3, subqi3, mulqi3): can do immediate with word insn.
(subsi3): use sub/neg to get reverse subtract (reduces reg shuffling).
(udivsi3): give up on having sign_expand_binop do this; people keep
breaking it. Manually extend unsigned SI to signed DI, then divide.
(xshfxx3): The options rank differently on different machines, so
spell them all out and enable the appropriate ones under TARGET_Cxx.
(sqrtxx2): Put under flag_fast_math.
(sinxx2, cosxx2): I don't know why these exist, but they do, so supply
them. The other microcoded intrinsics are in convex math.h.
(txtxx): Remove, no longer necessary.
(cmpdi): Add alternative to fake "eq.l #0,sk" with "neg.l sk,scratch".
(cmpqi): Omit, seems to produce marginally better cse than the old way.
(cmpsf): Avoid compare against 0.0 in ieee mode, since -0.0 is
possible and would confuse old ucode.
(movstrsi): Add.
(anon): Add patterns to pick up on dbra optimizations and implement the
sub/test part. (This optimizes out the compare against 0.)
(call, call_value): Use _pop form instead, and let convex.c replace
the pushes with fp stores.
(end): Put local variable list back.
convex.c (init_convex): New. Fill in tables used by convex.h.
(psw_disable_float): New. Turn off float exception enables to
make the environment more ieee-like.
(set_cmp): Change name to output_cmp.
(gen_cmp): Change name to output_condjmp. Add handling for
`neg.x' as a fake `eq.x #0' and for optimized-out compares
that read the carry of a preceding decrement.
(simplify_for_convex): New. Replace addr-(-const) with
addr+const so /bin/as will like the notation.
(expand_movstr): New. Generate pipelined load/store sequence.
(asm_declare_function_name): New. Output arg count for debuggers.
(print_operand): Moved from convex.h. Add %u and %v to fetch
subwords of a CONST_DOUBLE, %z to use in replacing shift by mul.
(print_operand_address): Moved from convex.h.
(outfloat): New, call REAL_VALUE_TO_DECIMAL.
(replace_arg_pushes): New. Replace sp by fp if possible; this does
not allow us to get rid of sp but stores are faster than pushes on
new machines.
(emit_ap_optimizations): New. Do simple live analysis of arg pointer
register and eliminate dead reloads.
math-convex.h: removed.
fixinc.convex: new file.

(start_enum): Set TREE_ADDRESSABLE on the tag here, and clear
current_local_enum.

parameter, for consistency with the C version (so we can make

cp-typeck.c, cp-parse.y: Fix calls to build_binary_op to pass

DECL_ASSEMBLER_NAME, since pushtag now mangles together
DECL_ASSEMBLER_NAME. This will make us emit `Q21D1B', not `Q221D1B'.
* cp-decl2.c (grokclassfn): Try using the local value for a nested
type if the IDENTIFIER_TYPE_VALUE isn't there.
Wed Dec 16 18:18:43 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
* cp-typeck.c (build_unary_op): Set TREE_CONSTANT on the address of
a function if it's static or external (i.e., staticp likes it).

* cp-tree.h (bad_specifiers): Add prototype.
* cp-decl.c (grokdeclarator): Use it in places where we had
replicated code.

out the context if it's an ERROR_MARK so the back-end won't die later.
* cp-type2.c (my_friendly_abort): Don't say anything like "please
fix above errors", just exit quietly.
* cp-lex.h (enum rid): Reordered for improved speed in grokdeclarator
when it does its linear search. RID_WCHAR is no longer in the
search path, since it's found by hand (as are RID_INT and RID_CHAR).
(RID_FIRST_MODIFIER): Start at RID_EXTERN now.
* cp-parse.y (overloaddef): Warn that using `overload' is an
anachronism.
Wed Dec 9 08:27:13 1992 Niklas Hallqvist (niklas at della.appli.se)
* cp-decl.c (init_decl_processing): Make sure the "unknown type"
typedecl gets ignored by the debuginfo generators.
Sun Dec 13 02:38:43 1992 Brendan Kehoe (brendan@cygnus.com)
* cp-search.c (lookup_nested_field): Check for assignment to members
of an enclosing class only when looking at a member, not at other
things (like nested types).
* cp-pt.c (type_unification): Only check that ARGS is a TREE_LIST if
it's non-null.
These four are from Niklas Hallqvist:
* cp-search.c (compute_visibility): Use the main variant when
testing if a member function belongs in the current class.
* cp-call.c (build_method_call): Don't look for constructors
called by initialization inside class methods in the classes'
bases (as opposed to inherited methods).
* cp-typeck.c (convert_for_initialization): In the case of
templates, make sure build_method_call knows which instantiation
of the class template we're initializing an object of.
* cp-decl.c (grokdeclarator): Instead of an assert, return a
NULL_TREE if the return_type's not return_ctor.
Sat Dec 12 23:52:25 1992 Brendan Kehoe (brendan@lisa.cygnus.com)

Fri Dec 4 13:53:01 1992 Brendan Kehoe (brendan@lisa.cygnus.com)

signal.h.
Wed Dec 2 15:51:34 1992 Mike Stump (mrs@cygnus.com)
* cp-call.c (build_method_call): Don't call abort for pure virtual
methods, instead, call the user-defined method. Addresses of pure
virtual methods are probably still wrong.
Wed Dec 2 14:44:41 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
* cp-call.c (convert_harshness): If parm's null for a reference (as
can be passed in), return 0.
Tue Dec 1 18:05:20 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
* cp-decl.c (grokdeclarator): Make member initialization be a
warning, not an error. Only issue it if not -pedantic, since
grokfield will issue an error when pedantic. Only warn about
constant members being initialized if `-ansi' is being used.
(finish_decl): Only complain about uninitialized const's that aren't
members when acting -pedantic, since we'll have already issued the
error about initializing a field.
* cp-type2.c (build_functional_cast): Revert change of Nov 2,
concerning clearing the TREE_VALUE of a default parameter.
Tue Dec 1 11:09:50 1992 Brendan Kehoe (brendan@lisa.cygnus.com)
* cp-call.c (build_method_call): When looking for a default arg
initialized by a ctor, be careful of a null ref w/ operand 1.
* cp-method.c (icat): Handle an argument of `1' first, since it's
the most common case.
Tue Dec 1 02:36:28 1992 Mike Stump (mrs@cygnus.com)
* cp-search.c (get_first_matching_virtual): Only set the
DECL_CONTEXT if the new context is a an unambiguous parent of the
previous context.
Tue Dec 1 02:20:32 1992 Mike Stump (mrs@cygnus.com)
Wed Nov 25 18:25:06 1992 Jim Wilson (wilson@sphagnum.cygnus.com)

is not accepted by all shells.
Mon Nov 23 13:21:43 1992 Brendan Kehoe (brendan@cygnus.com)
* c++ (-lm): Also recognize -lmath as a math library.
* c++ (first): Only shift if $first is no, on the chance we got no
arguments at all. If we didn't get anything, say so (since -lg++
will fake out the gcc driver into thinking we want to do something).
* cp-parse.y (paren_expr_or_null): New rule to emit an error when an
empty condition is used when it shouldn't.
(simple_if, stmt): Use it for `if', `while', and `do'.
* cp-decl.c (start_decl): If grokdeclarator returns a
void_type_node, return a NULL_TREE.
* cp-typeck.c (build_modify_expr_1): When calling build_opfncall for
`operator=', use make_node to create a plain NOP_EXPR for it to use,
rather than trying to pass NOP_EXPR down hoping it gets there intact.
(build_modify_expr): Ditto.
* cp-method.c (build_opfncall): Use TREE_CODE on ARG3 for a
MODIFY_EXPR, since it'll be coming in properly as a tree now.
Sat Nov 21 02:33:28 1992 Brendan Kehoe (brendan@cygnus.com)
* cp-init.c (expand_default_init): Clear DECL_REGISTER if we're
going to call a ctor, otherwise we may end up generating bogus and
confusing error messages about taking the addr of something declared
to be `register'.
* cp-typeck.c (build_x_function_call): Recognize a ptr-to-method

value in a register, record the fact for the call define_expands
and prologue expander to move the structure into the high part of
the register, and back again. If debugging, print if the argument
is a structure.
(mips_expand_prologue): Shift any QI/HI structures passed back, so
they can be used as normal QI/HI values.

setting HARSHNESS to 0 re: the conversion of the first argument.

type if the IDENTIFIER_TYPE_VALUE isn't there.
* cp-method.c (build_overload_nested_name): Use DECL_NAME instead of

DECL_ASSEMBLER_NAME. This will make us emit `Q21D1B', not `Q221D1B'.

* mips.c (epilogue_reg_mentioned_p): New function to return true
if any register used in the epilogue sequence is referenced. If

pass in that the prologue/epilogue has loaded the stack size into
$8 if large stack frame. Completely rewrite large stack frame
support, so that it doesn't abort if large stack frame, saved GP
registers, and no saved FP registers. If large stack frame, use
stack size stored in $8 if we can.
(function_prologue): Make tsize long.
(function_epilogue): Ditto.
(mips_expand_prologue): Ditto.
(mips_expand_epilogue): Ditto.
(mips_expand_prologue): Change call to save_restore_insns.

if the MEM was volatile, this will cause an extra load.

* cp-decl.c (pushdecl): Since the rest of the compiler wants to use
DECL_NAME for TYPE_DECLs, use that instead of DECL_ASSEMBLER_NAME.

pointer instead of incorrectly trying to convert at the bottom.
* cp-search.c (init_vbase_pointers): Changed to set up new
intermediate pointer.
