add explicit ABI and align options to pr88233.c

add explicit ABI and align options to pr88233.c

[Alexandre Oliva]

We've observed failures of this test on powerpc configurations that
default to different calling conventions and alignment requirements.
Both settings are needed for the expectations to be met.

This was regstrapped on x86_64-linux-gnu and ppc64-linux-gnu, and tested
with a cross to a ppc64-vxworks7r2 with both -mstrict-align and
-freg-struct-return enabled by default.  Ok to install?

	and calling conventions assumptions explicit.

[PATCH v2] add explicit ABI and align options to pr88233.c

[Alexandre Oliva]

Ping?

(modified version follows)


We've observed failures of this test on powerpc configurations that
default to different calling conventions and alignment requirements.
Both settings are needed for the original expectations to be met.

The test was later modified to have different expectations for big and
little endian code generation.  This patch restores the original
codegen expectations, that, with the explicit options, don't vary any
more.

Regstrapped on x86_64-linux-gnu and ppc64el-linux-gnu.  Also tested with
gcc-13 on ppc64-vx7r2 and ppc-vx7r2.  Ok to install?

More tolerance and less prejudice are key for inclusion and diversity
Excluding neuro-others for not behaving ""normal"" is *not* inclusive
