No, I didn't. I was wrong.

But I still don't understand why you think a new x87 instruction should be treated like any other SSE instruction. Maybe a new option should be added for that. -mno-sse will disable it even though you want to use the new x87 instruction but not SSE at all. This is why RTH was saying it should not be disabled by -mno-sse3.

Please read the code. You are incorrect. Please read the manual I linked to.
