Filter out invalid 'target' items from being passed to LLVM Craig noticed that CodeGen wasn't properly ignoring the values sent to the target attribute. This patch ignores them. This patch also sets the 'default' for this checking to 'supported', since only X86 has implemented the support for checking valid CPU names and Feature Names. One test was changed to i686, since it uses a lakemont, which would otherwise be prohibited in x86_64. Differential Revision: https://reviews.llvm.org/D39357 llvm-svn: 316783

Add support for the the target attribute. Modeled after the gcc attribute of the same name, this feature allows source level annotations to correspond to backend code generation. In llvm particular parlance, this allows the adding of subtarget features and changing the cpu for a particular function based on source level hints. This has been added into the existing support for function level attributes without particular verification for any target outside of whether or not the backend will support the features/cpu given (similar to section, etc). llvm-svn: 239579

Add support for tune= to the target attribute support by ignoring it. We don't currently support the -mtune option in any useful way so ignoring the annotation is fine. llvm-svn: 239580

Handle fpmath= in the target attribute. Right now we're ignoring the fpmath attribute since there's no backend support for a feature like this and to do so would require checking the validity of the strings and doing general subtarget feature parsing of valid and invalid features with the target attribute feature. llvm-svn: 239582

Fix sse4 for target attribute feature additions. This reinstates part of the hack removed in r233223, by special casing sse4 as part of the feature additions. The notable change here is that we consider it only as part of setting the SSE level and not as part of the actual target features set which handles setting the rest of the masks. llvm-svn: 241130

Handle sse turning on mmx, but no -mmx not turning off SSE. 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
