ee9e5f92b6 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

4ebcdf7396 hush: remove code to track PS1/2 values dynamically - it's too much work 
Assignments / exports / unsets of variables are far more frequent than
prompt printing, and if we show prompt, we are likely to be limited by
user typing speed - do not optimize for that scenario.
Just re-query $PS1 / $PS2 values when need to show the prompt.
