Yes. I see. The patch is in review. But no feedback although I had pinged it

Root cause:
When expand_call_stmt, if gimple_call_lhs (stmt) is NULL, it will set target to
const0_rtx.
Then when expand_atomic_test_and_set, it tries to emit_move_insn (subtarget,

Yes. gcc.target/i386/pr49095.c is still FAIL.
I have not found an easy way to fix it. The root cause for the FAIL is that:

Patch @r210457 enhances move_insn_for_shrink_wrap to sink more instructions out
