URL: https://github.com/llvm/llvm-project/commit/cc49ab77d8919830e4bdb2f9ce94e597a2025bf4 DIFF: https://github.com/llvm/llvm-project/commit/cc49ab77d8919830e4bdb2f9ce94e597a2025bf4.diff LOG: [Clang] Remove 't' from __builtin_amdgcn_global_atomic_fmin/fmax_f64 (#173969) Allows for type checking depending on the built-in signature. There is no `f32` version for both builtins.
