alias.c (can_address_p): No longer static.
* alias.c (can_address_p): No longer static.
* emit-rtl.c (get_mem_attrs): New parameter, MODE; all callers changed.
Return 0 if all parameters are default values.
(set_mem_attributes): Set MEM_KEEP_ALIAS_SET_P.
(adjust_address_1): Try harder to compute a size.
* expr.c (expand_assignment, store_constructor): If can't address,
set MEM_KEEP_ALIAS_SET_P.
(store_constructor_field): Don't change set if MEM_KEEP_ALIAS_SET_P.
(store_field): Likewise.
(store_constructor): Simplify call to store_constructor_field.
* expr.h (can_address_p): New declaration.
* gensupport.c (gen_rtx_CONST_INT): New function.
* rtl.h (MEM_KEEP_ALIAS_SET_P): New macro.
(MEM_SIZE): Get size from mode, if not set and not BLKmode.
(MEM_COPY_ATTRIBUTES): Copy MEM_KEEP_ALIAS_SET_P.
