Hi all,

Thanks for Aleksandar Beserminji great job:

https://reviews.llvm.org/D50437

It is not easy to reproduce the LLVMBUG-38221[1] by building OpenJDK8,
it needs some workaround

https://raw.githubusercontent.com/xiangzhai/jdk8u-dev/master/Workaround-compile-with-llvm.patch

LLVM toolchain[2] is just able to compile OpenJDK8 for mips64el now:

1. https://bugs.llvm.org/show_bug.cgi?id=38221#c10

2. $ clang -v
