Re: Test Harness and SPARC VIS Instructions

Hello!

This one looks like another test slipping another unsupported
instruction by.

0x020012b8 <fbar+40>: bne,pn %icc, 0x200138c <fbar+252>

Is this UltraSPARC and not V7?  Do we need two bad instructions
in the test case?

This is not-guarded runtime test. The problem is fixed by the attached patch.

Confirmed in my overnight run. See


It now looks like the scan-tree-dump-times tests are the next easy group that isn't supported that needs to be marked as not supported. I didn't see anything obv

I assume these fail because we don't dump files from the target.
How do you indicate these are not supported?

        * gcc.dg/vect/vect-align-2.c: Remove dg-do run directive.
        (main): Call check_vect.

Tested on x86_64-pc-linux-gnu, committed to mainline.
