* alias.c (can_address_p): Compnonents are not addressable if the containing type has alias set 0. (get_alias_set): Rework to use STRIP_NOPS. Only call front-end routine on object, type, or object with NOPs stripped, not inner values. Use language hook to call front-end routine. * builtins.c (get_memory_rtx): Always call set_mem_attributes. (expand_builtin_apply): Call set_mem_align on MEMs we make. Don't pass alignment to emit_block_move. (expand_builtin_memcpy, expand_builtin_va_copy): Likewise. (expand_builtin_memset): Likewise, but for clear_storage. * c-common.c (lang_get_alias_set): Renamed to c_common_alias_set and remove C++ specific parts. * c-common.h (c_common_get_alias_set): Add declaration. * c-lang.c (LANG_HOOKS_GET_ALIAS_SET): New macro. * calls.c (emit_call_1): Fix typo in sibcall_pop case. (save_fixed_argument_area): Call set_mem_align. Remove alignment in call to emit_block_move. (emit_library_call_value_1, store_one_arg): Likewise. (target_for_arg): Remove; disabled long ago. * emit-rtl.c (set_mem_attributes): Rework to only call get_mem_attrs once and similar cleanups. (offset_address): Use proper introductory comment. * expr.c (emit_block_move): Use alignment from that of MEM args, not from explicit operand; all callers changed. (clear_storage): Likewise. (expand_assignment): Don't call set_mem_alias_set on to_rtx. (store_field): Remove kludge on alias set used for to_rtx. (highest_pow2_factor, case *_DIV_EXPR): Never return 0. (expand_expr_unaligned): Call set_mem_attributes instead of set_mem_alias_set. * expr.h (emit_block_move, clear_storage): Remove ALIGN argument. * function.c (assign_stack_temp_for_type): Set MEM alignment. (expand_function_end): Track MEM attributes of trampolines. * ifcvt.c (noce_try_cmove_arith): Set alignment of new MEM. * integrate.c (copy_rtx_and_substitute, case CALL): Copy memory attributes from original. * langhooks.c (lang_hook_default_get_alias_set): New function. (hook_get_alias_set_0): New function. * langhooks.h (hook_get_alias_set_0): New declaration. (lang_hook_default_get_alias_set): Likewise. (LANG_HOOKS_GET_ALIAS_SET): New macro; add to initializer. * reload1.c (alter_reg): Use adjust_address_nv. * rtl.c (get_mode_alignment): Moved to here. * rtl.h (MEM_ALIGN): Take default from mode, if not BLKmode, and change default if unknown from 1 to BITS_PER_UNIT. * stor-layout.c (get_mode_alignment): Remove from here. * toplev.h (struct lang_hoks): Add get_alias_set field. * tree.h (lang_get_alias_set): Delete declaration. * config/arc/arc.c (arc_setup_incoming_varags): Set MEM alignment. * config/i386/i386.c (ix86_setup_incoming_varargs): Likewise. (ix86_va_arg): Likewise. * config/i960/i960.c (i960_setup_incoming_varargs): Likewise. * config/pa/pa.c (hppa_builtin_saveregs): Likewise. * config/sparc/sparc.c (sparc_va_arg): Likewise. * config/rs6000/rs6000.c (setup_incoming_varargs): Likewise. (expand_block_move_mem): Remove dead code. * cp/cp-lang.c (cxx_get_alias_set): New function. Point LANG_HOOKS_GET_ALIAS_SET to it. * f/com.c (LANG_HOOKS_GET_ALIAS_SET): New macro. (lang_get_alias_set): Delete. * java/lang.c (lang_get_alias_set): Deleted. From-SVN: r46442 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
