Clang's assembler does not like the syntax of the cmpdi:
arch/powerpc/boot/crt0.S:168:22: error: unexpected modifier on variable
reference
cmpdi 12,RELACOUNT@l
^
arch/powerpc/boot/crt0.S:168:11: error: unknown operand
cmpdi 12,RELACOUNT@l
^
Enclosing RELACOUNT in () makes it is happy. Tested with GCC 8 and Clang
8 (trunk).
Reported to clang as https://bugs.llvm.org/show_bug.cgi?id=38945
