clang-p2996/llvm/test/Transforms/InstCombine
History
Craig Topper 6749dc3446 [InstCombine] Don't transform bitcasts between x86_mmx and v1i64 into insertelement/extractelement 
x86_mmx is conceptually a vector already. Don't introduce an extra conversion between it and scalar i64.

I'm using VectorType::isValidElementType which checks for floating point, integer, and pointers to hopefully make this more readable than just blacklisting x86_mmx.

dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
