[Mesa-dev] [PATCH v2 10/45] swr/rast: Add autogen of helper llvm intrinsics.

George Kyriazis george.kyriazis at intel.com
Wed Apr 18 01:31:50 UTC 2018


Replace sqrt, maskload, fp min/max, cttz, ctlz with llvm equivalent.
Replace AVX maskedstore intrinsic with LLVM intrinsic. Add helper llvm
macros for stacksave, stackrestore, popcnt.
