(expand_call): Push the stack around function calls if stack_arg_under_construction is nonzero. Also copy structure_value_addr in that case. Push the stack around an inline function if it makes calls and there are outgoing arguments on the stack which must be preserved. Move the call to expand_cleanups_to before that. Do this stack adjustment before computing argument locations. Sun May 31 01:03:51 1992 Richard Stallman (rms@mole.gnu.ai.mit.edu) * sdbout.c (sdbout_symbol): Test DECL_IGNORED_P only for variables and types. * dwarfout.c (output_decl): Never ignore a FUNCTION_DECL even if DECL_IGNORED_P is set.

(RTX_COSTS): Don't use -mdebugd to set multiply costs to 2. * mips.c (output_movstrsi): Take an additional argument to determine whether this block move is a normal block move, or one that has been split. For the split block moves, there are two parts -- the first part is everything but the last store, and the second part is the last store, suitable to fill a delay slot. * mips.md (all define_splits): Don't do any define_split if -mdebugd. (movstrsi_internal*): Add support to split block moves into two pieces, one that is everything except for the last store, and the second piece, which is the last store that can fill a delay slot.

Wed Apr 15 14:18:27 1992 Mike Stump (mrs@rtl.cygnus.com) * cp-type2.c (readonly_warning_or_error): because the compiler is now warning about const alot more, for a release or two, lets just warn about const problems, just in case it is a compiler problem and not a user problem. * cp-cvt.c (build_up_reference): Lets get tougher on const problems on COMPONENT_REFs. Wed Apr 15 11:59:42 1992 Jim Wilson (wilson@sphagnum.cygnus.com) * cp-decl.c (finish_function): Check for any debug info enabled, not just DBX_DEBUG. Wed Apr 15 10:03:36 1992 Mike Stump (mrs@rtl.cygnus.com) * cp-cvt.c (build_up_reference): Propagate const and volatile down into the type so error checking works better. Tue Apr 14 11:44:32 1992 Mike Stump (mrs@rtl.cygnus.com) * cp-decl.c (start_decl): Shouldn't use flag_this_is_variable to make what this points to const, but I don't have the heart to do it right now. * cp-decl2.c (grokclassfn): Don't use flag_this_is_variable to make what this points to const. * cp-typeck.c (convert_arguments): Let build_up_reference handle const errors correctly.

Thu Apr 9 03:45:03 1992 Mark Eichin (eichin at cygnus.com) * cp-class.c (finish_struct): sanity check before calling popclass. If we're already hosed due to previous parse errors (specifically, we're not inside a class anymore) just report an error rather than crashing in popclass (if there wasn't a previous parse error, as the message suggests, we should get reports; this closes gcc/p0000525.) Wed Apr 8 08:56:49 1992 Mike Stump (mrs@rtl.cygnus.com) * cp-decl.c (grokdeclarator): Fix an eichin bug introduced seconds ago. Shame, he didn't put: Workaround for p869: 1) grokdeclarator (around cp-decl.c:7462) is using popclass(1) uses popclass(1) to close the pushclass(3) done by build_push_scope; however, it's coming around another time and popping all the way out, which leads to the core dump when do_friend is called from global scope (do_friend uses current_class_name to figure out whose friendship it is bestowing.) Current workaround: if (friendp) don't allow popping all the way out. We still need to figure out how to make sure it only gets called the *right* time; we also need to figure out if the correct scope is being used, but that's a matter of regression testing. into a ChangeLog entry. Wed Apr 8 01:10:44 1992 Mike Stump (mrs@rtl.cygnus.com) * cp-decl.c: Cleanup binding_levels_sane related code. Deleted argument, and changed to void type. Removed extraneous asserts. * cp-parse.y: Add fourth parameter to all finish_decl calls. Defaulted the guess to 0. * cp-decl.c: consistently use #if on all PARANOIDs.

Don't emit ldd/std for obviously unaligned address even when TARGET_HOPE_ALIGN. (output_fp_move_double): Call output_move_double for MEM cases. It is not safe to assume double reg addresses are always aligned. Tue Apr 14 07:55:47 1992 Torbjorn Granlund (tege@hal.gnu.ai.mit.edu) * *hp800*, *hp700*: Rename to *hppa* and *hppa1.1*, respectively. * config.sub: Recognize PA model numbers for PA 1.0 and 1.1.

Mon Apr 13 18:20:56 1992 Mike Stump (mrs@cygnus.com) * dwarfout.c: Add default definition for ASM_OUTPUT_ASCII as that is what varasm.c does now.

(movstrsi_internal): Add '=' constraint on all stores and clobbers. * decrose.h (LINK_SPEC): If not -noshrlib or -pic-none, pass -warn_nopic. Allow user to pass -noshrlib directly.

Tue Jan 14 14:38:09 1992 Michael Tiemann (tiemann at cygnus.com) * cp-typeck.c (build_unary_op): Call readonly_warning_or_error if ARG is TREE_READONLY (in addition to the type being TYPE_READONLY). * cp-init.c (maybe_adjust_addr_for_delete): If the adjustment needs to be done, zero out the storage that held part of the cookie. Tue Jan 14 13:12:48 1991 Ron Guilmette (rfg at ncd.com) * c-decl.c (poplevel): Set TYPE_CONTEXT for each tagged type except inside function declaration parm list. (grokdeclarator): Set TYPE_CONTEXT for tagged type in decl parm list. (pushtag): Don't set TYPE_CONTEXT for tagged types here. Tue Jan 14 06:46:37 1992 Richard Kenner (kenner at vlsi1.ultra.nyu.edu) * global-alloc.c (global_alloc): Count multi-word pseudos correctly in local_reg_n_refs. (find_reg): Evict pseudos that overlap the register we take, not just that start with that register. * a29k.c (a29k_debug_reg_map): New variable. (output_prologue): Initialize it. * a29k.h (DBX_REGISTER_NUMBER): Use that map. * ultrix.h (WCHAR_TYPE): Make definition be a known type. * final.c (final_scan_insn): Call DBR_OUTPUT_SEQEND before we clear `final_sequence', so it can call dbr_sequence_length. * reload1.c (reload): Clear insn_needs once we know we have reloads, instead of always. Don't skip processing of reloads for CALL_INSNs when caller-save needs a spill register. * flow.c (mark_used_regs, case RETURN): Insert missing test for global registers. * reorg.c (mark_referenced_resources): Mark asm's as volatile when appropriate. * integrate.h (struct inline_remap): New field const_equiv_map_size. * integrate.c (expand_inline_function): Set it; make larger map. (subst_constants): Don't reference out-of-range entry in equiv map. * unroll.c (unroll_loop): Set const_equiv_map_size. See ChangeLog.4 for earlier changes.
