Hi there!

I made a patch which fixes regressions on ARM platforms with disabled unaligned accesses. The problem is that 'arm_vect_no_misalign' predicate do not check 'unaligned_access' global variable to determine whether unaligned access to vector are allowed. This leads to spurious vect.exp test fails when GCC is configured --with-specs=%{!munaligned-access:-mno-unaligned-access}.

Attached patch fixes ARM predicate and several tests to correctly handle the issue.

The following targets were reg. tested for multiple targets (ARM, Thumb-1, Thumb-2, x86, x86_64) with and without -mno-unaligned-access. Analysis showed patch affects only vect.exp tests so only vect.exp was tested.

For x86, x86_64, ARM without -mno-unaligned-access, Thumb-2 without -mno-unaligned-access and Thumb-1 no regressions occured. For ARM/Thumb2 with -mno-unaligned-access patch fixed most of failures but triggered some problems (see attached log) for current vect.exp tests:
1) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61887
2) Some XPASS'es due to unexpected loop versioning (e.g. gcc.dg/vect/pr33804.c). 3) After predicate fix some passing tests which require unaligned vector support become NA (this was expected).

Here is new version of patch and regression log. On the current trunk results are slightly different due to patches for Richard Biener (no UNRESOLVED fails) but some PASS->XPASS regressions still remain (see attachment):

PASS->XPASS: gcc.dg/vect/if-cvt-stores-vect-ifcvt-18.c scan-tree-dump-times vect "vectorized 1 loops" 1 PASS->XPASS: gcc.dg/vect/pr33804.c -flto -ffat-lto-objects scan-tree-dump-times vect "vectorized 1 loops" 1
etc.

These XPASS'es are due to code versioning: current GCC creates 2 versions of loop: aligned and misaligned. It's look like they are slightly out of date at lest for ARM.

As is this line.

I think you can restrict the check to defined(__ARM_FEATURE_UNALIGNED)
&& defined(__ARMEL__)

  __ARM_FEATURE_UNALIGNED should tell you whether unaligned access is
allowed or not, therefore you should no longer require any specific
"architectural" checks.


         #error FOO
         #endif

I'm not sure about the original intent of the tests right now.

Thank you Ramana!
