            Bug ID: 101208
           Summary: libffi.call/nested_struct12.c fails on aarch64
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libffi
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---
            Target: aarch64-linux-gnu

Mostly filing just to record this test failing.
>From IRC:
[03:09] <jakub> ktkacho2: seems my new nested_struct12.c libffi testcase FAILs
on aarch64, doesn't aarch64 libffi have a similar bug to the one that got fixed
on x86_64?
[03:10] <jakub> ktkachov2: ^^^; passes on all other targets I've tested
(armv7hl, s390x, ppc64le, x86_64, i686)
[03:20] <ktkachov2> jakub: I'm afraid I don't know much about that area
[03:23] <jakub> James Greenhalgh and Marcus Shawcroft did the libffi port, but
haven't seen them on gcc-patches for a while; anyone else in ARM would be
familiar with libffi?  I'm afraid I don't know anything about aarch64 parameter
passing rules

Just for reference the x86_64 fix was r12-1524 .

It's passing in upstream libffi...

...so check for any fixes that weren't migrated to gcc.

Fixed when the libffi was synced with the upstream.
