Don't assume it's AVX_U128_CLEAN after call_insn whose abi.mode_clobber(V4DImode) deosn't contains all SSE_REGS.
If the function desn't clobber any sse registers or only clobber
128-bit part, then vzeroupper isn't issued before the function exit.
the status not CLEAN but ANY after the function.
Also for sibling_call, it's safe to issue an vzeroupper. Also there
could be missing vzeroupper since there's no mode_exit for
sibling_call_p.
gcc/ChangeLog:
PR target/112891
* config/i386/i386.cc (ix86_avx_u128_mode_after): Return
AVX_U128_ANY if callee_abi doesn't clobber all_sse_regs to
align with ix86_avx_u128_mode_needed.
(ix86_avx_u128_mode_needed): Return AVX_U128_ClEAN for
sibling_call.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr112891.c: New test.
* gcc.target/i386/pr112891-2.c: New test.
