James Y Knight <foom at fuhm dot net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |foom at fuhm dot net --- Comment #3 from James Y Knight <foom at fuhm dot net> --- This is a mess. Clang gets it "right" only through a really awful hack, which breaks std::rethrow_exception, and which I'm now proposing to remove. See https://github.com/llvm/llvm-project/issues/55340#issuecomment-1152755112 I don't believe there's a way to actually get this correct in the Itanium ABI as it stands.
