* [x86] AVX FP compare builtins should require AVX target feature (PR28112)Sanjay Patel2016-06-211-1/+32
| | | | | | | | | | | | | | | | | This is a fix for PR28112: https://llvm.org/bugs/show_bug.cgi?id=28112 The FP comparison intrinsics that take an immediate parameter (rather than specifying a comparison predicate in the function name) were added with AVX; these are macros in avxintrin.h. This patch makes clang behavior match gcc (error if a program tries to use these without -mavx) and matches the Intel documentation, eg: VCMPPS: m128 _mm_cmp_ps(m128 a, __m128 b, const int imm) 'V' means this is intended to only work with the AVX form of the instruction.

* Provide a frontend based error for always_inline functions that requireEric Christopher2015-11-121-0/+7
target features that the caller function doesn't provide. This matches the existing backend failure to inline functions that don't have matching target features - and diagnoses earlier in the case of always_inline. Fix up a few test cases that were, in fact, invalid if you tried to generate code from the backend with the specified target features and add a couple of tests to illustrate what's going on. This should fix PR25246. llvm-svn: 252834
