GCC trunk gets an internal compiler error when building SPEC CPU2000 test
164.gzip with "-O2 -floop-interchange" on powerpc-linux, as demonstrated by a
minimized testcase that I'll attach to this PR.
elm3b149% /home/janis/tools/gcc-trunk-anonsvn/bin/gcc -c -O2 -floop-interchange
bug.c
bug.c: In function inflate_fixed:
bug.c:56:1: internal compiler error: tree check: expected ssa_name, have
integer_cst in detect_commutative_reduction, at graphite-sese-to-poly.c:2654
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
A Graphite-enabled trunk build is broken during the 19-hour range from r150250
to 150300. The test passes with the build just before that range and fails
with r150301, the first revision that builds after a merge from the Graphite
branch.
