Hello!
Can someone familiar with VIS provide an instruction
that is OK to do a run-time test with to check if
it is supported?
Perhaps this fragment from testsuite/gcc.dg/vect/tree-vect.h may help:
#elif defined(__sparc__)
asm volatile (".word\t0x81b007c0");
Thanks. That helped a lot. Now I only see these cases on vect.exp

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?
