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 Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
