Commit Message

David Edelsohn Feb. 28, 2018, 7:58 p.m. UTC 
AIX 7.1 continues to support Power4 as the minimum ISA level, so this
reverts the recent patch to aix71.h.

AIX 7.2 requires Power7 as the minimum ISA level.  The second part of
this patch adds a new aix72.h file and updates config.gcc.

Thanks, David

* config.gcc (powerpc-ibm-aix7.1.*): New stanza.
(powerpc-ibm-aix[789]*): Default to AIX 7.2.
* config/rs6000/aix71.h (TARGET_DEFAULT): Revert to Power4 ISA.
* config/rs6000/aix72.h: New file.
