GCC trunk gets an internal compiler error when building SPEC CPU2006 test
447.dealII on powerpc64-linux with "-O2 -fgraphite-identity" or "-O2
-floop-parallelize-all" for either -m32 or -m64, as demonstrated by a minimized
testcase that I'll attach to this PR. Perhaps someone else will be able to
minimize it more.
elm3b149% /home/janis/tools/gcc-trunk-anonsvn/bin/g++ -c -O2
-fgraphite-identity bug.cc
bug.cc: In member function ‘void Base<dim>::getf2d(vector<Tensor<2, dim> >&)
const [with int dim = 3]’:
bug.cc:38:6: internal compiler error: in expand_scalar_variables_expr, at
sese.c:907
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
The testcase and dealII compile correctly with GCC 4.4.2 using "-O2
-fgraphite-identity". The failure starts with this patch:

Is this bug still around (r156830)? I have a 64 bit linux machine and it seems
to be fine.

different testcase, reduced
Fails at all -O1, -O2 and -O3 levels. I am not sure if it is the same problem,
but it fails at the same place, so I am attaching it here.

I believe this commit introduced the bug:
Remove COMPONENT_REF limitation in SCoP detection.
2010-01-08 Sebastian Pop <sebastian.pop@amd.com>
* graphite-scop-detection.c (exclude_component_ref): Removed.
(is_simple_operand): Removed.
(stmt_simple_for_scop_p): Remove use of is_simple_operand.
git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/graphite@155738
We allow SCoPs that we cannot handle in the backend.
