Subject: [AVX-512] Replace 512-bit masked packss/packus builtins and replace with new unmasked... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4fda345b958bd5f9c909aa307e039b517c852a42;p=clang

[AVX-512] Replace 512-bit masked packss/packus builtins and replace with new unmasked builtins.

These new unmasked builtins will enable us to easily support optimizing these builtins in InstCombine in the backend.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@295291 91177308-0d34-0410-b5e6-96231b3b80d8
