I am trying to understand RTL for my thesis.
I have one question about conditional code register
(cc0) in gcc.
1) DO I need to specify somewhere that that flags
register is cc0.
or is it that, since cc0 is pseudo
when doing operations which can set flags,
I need to call CC_STATUS_INIT.
and when doing operations which preserve flags
I can say cc_status = cc-Prev_status.
I am wrong please correct my understanding .
thanks and regards
