--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The reason is that in order to match pandn in bar, it relies on the stv pass
being done, and TARGET_STV is disabled if -mpreferred-stack-boundary={2,3}, or
-mincoming-stack-boundatry={2,3} or -mstackrealign. The last one is what
matters on Solaris (and on cygming too?), because those define
STACK_REALIGN_DEFAULT to non-zero.
I'd say we should just add -mno-stackrealign to dg-options in that testcase.
