            Bug ID: 98181
           Summary: Add support for FreeBSD on powerpc64le
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org

patch

FreeBSD has recently added support for powerpc64le architecture (ppc64le using
Linux naming). FreeBSD and GCC both had previously supported powerpc64 (ppc64
using Linux naming) so this patch is pretty simple, it only adds endianness
detection using similar code that Linux code uses.

While here, also clear the issue of default tuning. People that still use
32-bit POWER are likely on G4, so tune for that. On 64-bits, tune for POWER8
(similarly to Linux). Also remove the obsolete comment that FreeBSD doesn't
support anything newer than PPC970 - it works nice on my POWER9 workstation.

Please send patches to the gcc-patches mailing list, rather than in bugzilla.

I believe this has been addressed and Segher committed patches for that,
so closing this.

Please advise in case there's something missing.

I should have looked if there was a PR for this, sorry.  This was:

    rs6000: Add support for powerpc64le-unknown-freebsd

    This implements support for powerpc64le architecture on FreeBSD.  Since
    we don't have powerpcle (32-bit), I did not add support for powerpcle
    here. This remains to be changed if there is powerpcle support in the
    future.
