This is complicated. `half` is a valid type regardless of whether or not 16bit types are enabled, and `half` is a _distinctly different_ type when 16-bit types are enabled. What this does is put the availability annotation on the 16-bit `half` type's overloads, but not the 32-bit `half` type's overloads. That way if you're writing a shader for SM 6.0, using 32-bit `half` you get don't get blocked by the SM 6.2 availability annotation. https://github.com/llvm/llvm-project/pull/81782 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
