md.texi (setmem): Document new parameter.
* md.texi (setmem): Document new parameter.
* optabs.c (maybe_gen_insn): Support 9 operands.
* builtins.c (determine_block_size): Add probable_max_size;
support anti-ranges.
(expand_builtin_memcpy. expand_builtin_memset_args): Pass around
probable_max_size.
* expr.c (emit_block_move_via_movmem, emit_block_move_hints,
emit_block_move, clear_storage_hints, set_storage_via_setmem):
Likewise.
* expr.h (emit_block_move_hints, clear_storage_hints,
set_storage_via_setmem): Update prototype.
* i386.md (setmem, movmem patterns): Add 9th operand.
* i386-protos.h (ix86_expand_set_or_movmem): Update prototype.
* i386.c (ix86_expand_set_or_movmem): Take probable_max_size_exp
argument; pass it to decide_alg.
* gcc.target/i386/memcpy-3.c: New testcase.
