The patch looks good but I am not familiar with PPC instructions enough. Could you please run the runtime tests from here: https://github.com/llvm/llvm-test-suite/tree/main/MultiSource/UnitTests/Float/rounding? You just need to build application from two files: `clang rounding.c rounding-dynamic.c`.
