networking: cc is not a register
gcc accepts
__asm__ ( "" : : : "%cc");
but cc is not a real register and clang does not like it.
networking/tls_pstm_montgomery_reduce.c:385:4: error: unknown register name '%cc' in asm
| INNERMUL;
| ^
The % syntax nominally goes before a register, in this case cc,
like "memory" isn't a true register it's just a way of specifying that
the condition code registers for the target are clobbered
