            Bug ID: 101865
           Summary: _ARCH_PWR8 is not defined when using -mcpu=3Dpower8
           Product: gcc
           Version: 11.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tuliom at ascii dot art.br
  Target Milestone: ---

When using -mcpu=3Dpower8, I expected that _ARCH_PWR8 would be defined, how=
ever
it isn't defined when used together with -mno-altivec -mno-vsx, e.g.

$ gcc-11 -mcpu=3Dpower8 -mno-altivec -mno-vsx -dM -E - < /dev/null | grep P=
WR
#define _ARCH_PWR5 1
#define _ARCH_PWR6 1
#define _ARCH_PWR7 1
#define _ARCH_PWR5X 1
#define _ARCH_PWR4 1=
