The patch which introduced this testcase:

I thought I reported this failure to Paolo but I can't find the email.

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

Subject: Re:  gcc.dg/tree-ssa/vrp47.c fails on powerpc

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.

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

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.
