When compiled with --code-model=large --relocation-model=static, LLVM emits PC relative relocations in the .eh_frame section. Loading it then causes a waring to be printed.
AFAICT, the actual relocation is not actually used by any existing tools which is why I'm not adding any test. This also seems to be the case for X86 ref https://reviews.llvm.org/D67779 . The only test done is confirming that this fixes the warning with llvm-dwarfdump.
