...le, the availability of a 2-lane double precision `sin` function via SVML when targeting AVX on x86 is provided by the following IR. // ... ... = call double @sin(double) #0 // ... #0 = { vector-variant = {"_ZGVcN2v_sin(__svml_sin2), _ZGVdN4v_sin(__svml_sin4), ..."} } The string `"_ZGVcN2v_sin(__svml_sin2)"` in this vector-variant attribute provides information on the shape of the vector function via the string `_ZGVcN2v_sin`, mangled according to the Vector Function ABI for Intel, and remaps the standard V...

Hi all, I am submitting the following RFC [1] to re-implement -fveclib via OpenMP constructs. The RFC was discussed during a round table at the last LLVM developer meeting, and presented during the BoF [2]. The proposal is published on Phabricator, for the purpose of keeping track of the comments, and it now ready for a review from a wider audience after being polished by Hal Finkel and Hideki
