From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/ChangeLog-2004 | 47887 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47887 insertions(+) create mode 100644 gcc/ChangeLog-2004 (limited to 'gcc/ChangeLog-2004') diff --git a/gcc/ChangeLog-2004 b/gcc/ChangeLog-2004 new file mode 100644 index 000000000..d48c31aca --- /dev/null +++ b/gcc/ChangeLog-2004 @@ -0,0 +1,47887 @@ +2004-12-31 Richard Henderson + + PR tree-opt/19042 + * tree-sra.c (decide_block_copy): Force use_block_copy false + for complex values. + +2004-12-31 Richard Henderson + + PR middle-end/17799 + * function.c (use_register_for_decl): Check DECL_IGNORED_P instead + of DECL_ARTIFICIAL. + (assign_parms_augmented_arg_list): Set DECL_IGNORED_P. + * c-decl.c (build_compound_literal): Likewise. + * dwarf2asm.c (dw2_force_const_mem): Likewise. + * gimplify.c (create_artificial_label): Likewise. + * tree-inline.c (expand_call_inline): Likewise. + * var-tracking.c (vt_initialize): Likewise. + * tree-outof-ssa.c (create_temp): Copy DECL_IGNORED_P. + +2004-12-31 Andrew Pinski + + PR target/19211 + * config/darwin.c (machopic_legitimize_pic_address): If the orig + is subregister return orig. + +2004-12-31 Zdenek Dvorak + + * tree-scalar-evolution.c (instantiate_parameters_1): Copy the + expression only if needed. + +2004-12-31 John David Anglin + + * pa-hpux.h (HANDLE_SYSV_PRAGMA, HANDLE_PRAGMA_PACK_PUSH_POP): Define. + +2004-12-31 Hans-Peter Nilsson + + PR target/18701 + * combine.c (combine_simplify_rtx): Do not allow paradoxical + subregs of MEM. + + PR target/18701 + * combine.c (gen_lowpart_for_combine): When stripping SUBREG of + MEM, adjust imode and isize. + +2004-12-30 Richard Henderson + + * config/ia64/ia64.c (hfa_element_mode): Return false for + zero-sized top-level aggregates. + +2004-12-30 Jan Hubicka + + PR target/18019 + * i386.md (movqi_1): Fix -Os instruction choice. + +2004-12-30 Steven Bosscher + + * global.c (regclass_intersect): Remove. + (mark_reg_use_for_earlyclobber): Use reg_classes_intersect_p instead. + +2004-12-30 Richard Henderson + + * config/ia64/ia64.c (ia64_function_value): Use PARALLEL for + aggregates with XF/XCmode. + +2004-12-29 Richard Henderson + + * target.h (targetm.calls.arg_partial_bytes): New. + * target-def.h (TARGET_ARG_PARTIAL_BYTES): New. + * calls.c (store_unaligned_arguments_into_pseudos): Update for + partial in bytes. + (load_register_parameters): Likewise. + (store_one_arg): Likewise. + (initialize_argument_information): Use targetm.calls.arg_partial_bytes. + (emit_library_call_value_1): Likewise. + * expr.c (block_move_libcall_safe_for_call_parm): Likewise. + (emit_push_insn): Update for partial in bytes. + * expr.h (FUNCTION_ARG_PARTIAL_NREGS): Remove. + * function.c (assign_parm_find_entry_rtl): Use + targetm.calls.arg_partial_bytes.
