Subject: tcg: Stash MemOp size in TCGOP_FLAGS
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bf7ca5fb3032b95fd83dbb9883e904ee28baa229;p=thirdparty%2Fqemu.git

tcg: Stash MemOp size in TCGOP_FLAGS

This will enable removing INDEX_op_qemu_st8_*_i32,
by exposing the operand size to constraint selection.
