REGISTER_KIND for PPC64 and PPC32 is defined here: https://github.com/llvm/llvm-project/blob/bab39816085d715e52c2131fa249ccd10178764b/libunwind/src/libunwind.cpp#L52-L55 Apparently __ppc__ is not defined by GCC, but probably it is defined by Clang. GCC on PPC32 defines: PPC, __PPC, __PPC__, _ARCH_PPC, powerpc, __powerpc, __powerpc__ Sam James confirmed that manually appending -D__ppc__ to CFLAGS / CXXFLAGS fixes compilation failure. Possible simple solution in ebuild: if use ppc && tc-is-gcc; then append-flags -D__ppc__ fi
Fixes: https://github.com/llvm/llvm-project/commit/cd20e579df07517a4ddbf6eef58b96d04f6bd9a9 https://github.com/llvm/llvm-project/commit/11c2ef5638c3cff489744f1d342cd92e2a864614
Fixed in 13.0.1 (backported in Gentoo).
