[PATCH] testsuite, arm: Fix up pr112337.c test

[Saurabh Jha]

[-- Attachment #1: Type: text/plain, Size: 847 bytes --]

Hey,

I introduced this test "gcc/testsuite/gcc.target/arm/mve/pr112337.c" in this commit 2365aae84de030bbb006edac18c9314812fc657b before. This had an error which I unfortunately missed. This patch fixes that test.

Did regression testing on arm-none-eabi and found no regressions. Output of running gcc/contrib/compare_tests is this:

"""
Tests that now work, but didn't before (2 tests):

arm-eabi-aem/-marm/-march=armv7-a/-mfpu=vfpv3-d16/-mfloat-abi=softfp: gcc.target/arm/mve/pr112337.c (test for excess errors)

"""

Ok for trunk? I don't have commit access so could someone please commit on my behalf?

Regards,
Saurabh

Hmm, could this be related to the changes Christophe made recently to change the way MVE vector types were set up internally?  If so, this might indicate an issue that's going to affect real users with existing code.

Christophe?

My change was only about vector types, here the problem is with a
pointer to a scalar.
Anyway, I ran the test with my commit reverted and it still fails in
the same way, so I think this patch is needed.

Thanks,

Ok, thanks for checking.  In that case, Saurabh, your patch is OK, but please change 'Fix testcase' to 'Use int32_t instead of int.'

Note that ChangeLog entries end with a full stop.
