Confirming that this also still fails on i386-pc-solaris2.10.

Should probably change the bug title and the target as it fails on more than
just powerpc.

--- Comment #17 from Pat Haugen <pthaugen at gcc dot gnu.org> ---
This test no longer fails on powerpc after my patch to make powerpc*-*-* a
logical_op_short_circuit target
(https://gcc.gnu.org/ml/gcc-patches/2014-07/msg00637.html).

Searching the test-results, looks like m68k is the only other target where it's
still failing(https://gcc.gnu.org/ml/gcc-testresults/2014-07/msg00700.html).
More than likely for the same reason since it looks like that target doesn't
define LOGICAL_OP_NON_SHORT_CIRCUIT or BRANCH_COST, which means it should
default to false.

See the same on hppa1.1-hp-hpux10.20 but not on hppa2.0w-hp-hpux11.11:

I think it is the same, I will verify.

I'm seeing the same on i386-unknown-freebsd7.1.

FAIL: gcc.dg/tree-ssa/vrp47.c scan-tree-dump-times vrp1 "[xy][^ ]* !=" 0

Is this the same issue, or should I open a different report?

I'd rather do so only on the branch when it is created.  I'm pretty
sure this can be fixed, but it's probably not stage4 stuff.

See the analysis in http://gcc.gnu.org/ml/gcc-patches/2009-01/msg00801.html
which skips the test for MIPS targets.
