Created attachment 61547 [details] [review] Filter out -Wcovered-switch-default from LLVM_CFLAGS Removing from LLVM_CFLAGS is enough to fix the build. ping? Commited, thanks. But I don't understand why `llvm-config --cppflags` is passing ordinary non-CPP related flags. This should also be fixed upstream. |
