Double checking: do you plan on addressing this for other platforms? I saw that CL 42347577/42336969 “[Linux] Fix toolchain version check to disallow llvm 19 for now” removed support for Clang 19, which suppresses this issue for the time being as well.
Also, wondering whether application of rsqrtss as described in VCToolchain.cs applies to other platforms as well in terms of (lack of) precision.
