From 07ce0b05300de5bc8f1932a4cfbe38f3323e5ab1 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 9 Dec 2020 13:58:39 -0600 Subject: tcg: Introduce INDEX_op_qemu_st8_i32 Enable this on i386 to restrict the set of input registers for an 8-bit store, as required by the architecture. This removes the last use of scratch registers for user-only mode.
