emit-rtl.c (last_call_insn, [...]): New functions.
* emit-rtl.c (last_call_insn, add_function_usage_to): New functions. * rtl.h (last_call_insn, add_function_usage_to): New prototypes. * builtins.c (expand_builtin_apply): Use the new emit-rtl functions. * calls.c (emit_call_1): Likewise. (expand_call): For calls initializing constant memory, replace emission of standalone mem /u clobber with function usage entry. * expr.c (emit_block_move_via_libcall): Likewise. * cse.c (count_reg_usage, case EXPR_LIST): New case. * flow.c (propagate_one_insn): Pass entire operand of CALL_INSN_FUNCTION_USAGE to mark_used_regs. * integrate.c (try_constants): For CALL_INSNs, substitute constants within the FUNCTION_USAGE also. * loop.c (prescan_loop): Note clobbers of const mem mentioned in FUNCTION_USAGE lists. * reload1.c (replace_pseudos_in): Renamed. (reload): Use it for clobbers surviving until the end of the reload. From-SVN: r66429
