URL: https://github.com/llvm/llvm-project/commit/6bea9ff91378571b3bedcdc12fac7bb916371871 DIFF: https://github.com/llvm/llvm-project/commit/6bea9ff91378571b3bedcdc12fac7bb916371871.diff LOG: [HLSL] Add WaveActiveCountBits as Langugage builtin function for HLSL One clang builtins are introduced uint WaveActiveCountBits( bool bBit ) as Langugage builtin function for HLSL. The detail for WaveActiveCountBits is at https://github.com/microsoft/DirectXShaderCompiler/wiki/Wave-Intrinsics#uint-waveactivecountbits-bool-bbit- This is only clang part change to make WaveActiveCountBits into AST. llvm intrinsic for WaveActiveCountBits will be add in separate PR.
