Hello,

It is not, something is wrong with LLVM 12 on PowerPC64. Clang is crashing
before main:


Starting program: /usr/bin/cc

Program received signal SIGSEGV, Segmentation fault.
0x0000000011530708 in _GLOBAL__sub_I_cc1_main.cpp ()

I think no one has had time to investigate it and find out what is
happening yet.
LLVM 11 worked fine.

Cheers,
