            Bug ID: 115681
           Summary: libffi.closures/single_entry_structs2.c FAILs on
                    32-bit SPARC
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libffi
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: ebotcazou at gcc dot gnu.org
  Target Milestone: ---
            Target: sparc-sun-solaris2.11, sparc-unknown-linux-gnu

Since the libffi 3.4.2 import on 20211020, the
libffi.closures/single_entry_structs2.c
test FAILs on 32-bit SPARC (both Linux and Solaris):

FAIL: libffi.closures/single_entry_structs2.c -W -Wall -Wno-psabi -O0 execution
test

In current upstream libffi, the failure persists, and there are quite a number
of additional ones.  I've reported them as
https://github.com/libffi/libffi/issues/841
and finally posted a proposed patch there.

When/if that's accepted upstream, it should be cherry-picked into the gcc tree,
I believe.
