Created attachment 28995
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28995
gcc48-pr55562.patch
Broken by the http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=192969 sbitmap
changes. modulo-sched.c seemed to be using sbitmap_a_and_b_cg in 4 places,
that change replaced that by bitmap_and, but apparently the new function only
returns non-zero (something changed) if destination sbitmap has popcount.
sbitmap_a_and_b_cg on the other side asserted it doesn't have popcount.

Can somebody please test this on ppc? I'll bootstrap/regtest it on
x86_64-linux and i686-linux momentarily.

I did a quick test on powerpc-ibm-aix and the patch seems to fix the problem.
You should have access to a lot of PPC systems for testing.
