Hi Martin, Thanks for your response!
I haven't tested compiling OpenJDK 12-dev with LLVM toolchain, perhaps the issue had been fixed already, because clang treat invalid argument '-std=gnu++98' not allowed with 'C' as error. It is better only apply EXTRA_CFLAGS to C without EXTRA_CXXFLAGS.
Furthermore, I just have interest, did you use clang analyzer, sanitizer and libfuzzer towards hotspot and jdk native library? Thanks!

We seem to have some confusion about flags for C vs. flags for C++. Most flags for most toolchains apply to both C and C++, so it's understandable that we want to unify them. But some flags, notably -std, are language-specific. We have both EXTRA_CFLAGS and EXTRA_CXXFLAGS, so we should expect EXTRA_CFLAGS to only apply to C.
