The code to set floating-point state when MXCSR changes calls set_flush_to_zero on &env->fp_status, so affecting the x87 floating-point state rather than the SSE state. Fix to call it for &env->sse_status instead. Signed-off-by: Joseph Myers <joseph@codesourcery.com> --- target/i386/fpu_helper.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
