Subject: * 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.
