--- Comment #1 from Pat Haugen <pthaugen at gcc dot gnu.org> --- Created attachment 30841 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30841&action=edit Source file pdv.f source file from benchmark, which results in successful execution if compiled with prior revision (r202429). Should have noted in prior comment, compile options used when building the benchmark are: -m64 -O3 -mcpu=power7 -fno-tree-loop-distribution -fno-tree-vectorize (Note that failure still exists for just "-m64 -O3 -mcpu=power7" other 2 options were just included while trying to narrow down dumps/assembler for debugging.) Compiling with -fno-tree-loop-distribute-patterns results in benchmark success.
