[llvm-dev] Can't find x86 AVX VPANDNPS intrinsic
Hello all - I'm trying to find the llvm intrinsic name for the VPANDNPS AVX instruction to be able to call the intrinsic directly (usually something like x86_avx2_xxx). Usually google or a search through the .td files or source turns something up, but I'm stumped with this one. Any help would be much appreciated. Thanks - Matt -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20151231/12aeb2cb/attachment.html>

[llvm-dev] Can't find x86 AVX VPANDNPS intrinsic
Hi Matt - I think this should either be VPANDN (integer) or VANDNPS (float); there is no "VPANDNPS".

I don't think there is an intrinsic. This is supported by native IR by looking for something like (and %a, (xor %b, -1)) On Thu, Dec 31, 2015 at 1:25 PM, Sanjay Patel via llvm-dev < llvm-dev at lists.llvm.org> wrote:> Hi Matt - > I think this should either be VPANDN (integer) or VANDNPS (float); there > is no "VPANDNPS". > > On Thu, Dec 31, 2015 at 1:32 PM, Matthew Stoll via llvm-dev < > llvm-dev at lists.llvm.org> wrote: > >> Hello all - >> >> I'm trying to find the llvm intrinsic name for the VPANDNPS AVX >> instruction to be able to call the intrinsic directly (usually something >> like x86_avx2_xxx).
