*	[X86] Correct the value of MaxAtomicInlineWidth for pre-586 cpus	Craig Topper	2019-03-21	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	Use the new cx8 feature flag that was added to the backend to represent support for cmpxchg8b. Use this flag to set the MaxAtomicInlineWidth. This also assumes all the cmpxchg instructions are enabled for CK_Generic which is what cc1 defaults to when nothing is specified.

*	Handle sse turning on mmx, but no -mmx not turning off SSE.	Eric Christopher	2015-10-08	1	-0/+22
	Rationale : // sse3 __m128d test_mm_addsub_pd(__m128d A, __m128d B) { return _mm_addsub_pd(A, B); } // mmx void shift(__m64 a, __m64 b, int c) { _mm_slli_pi16(a, c); _mm_slli_pi32(a, c); _mm_slli_si64(a, c); _mm_srli_pi16(a, c); _mm_srli_pi32(a, c); _mm_srli_si64(a, c); _mm_srai_pi16(a, c); _mm_srai_pi32(a, c); } clang -msse3 -mno-mmx file.c -c For this code we should be able to explicitly turn off MMX without affecting the compilation of the SSE3 function and then diagnose and error on compiling the MMX function. This is a preparatory patch to the actual diagnosis code which is coming in a future patch. This sets us up to have the correct information where we need it and verifies that it's being emitted for the backend to handle. llvm-svn: 249733
