alias.c (can_address_p): Compnonents are not addressable if the containing type has alias set 0.
* 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.
