[LLVMdev] pb05 benchmarks for llvm/dragonegg 3.2

[Jack Howarth]

Duncan,
   With the commit from http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121203/158488.html,
the Polyhedron 2005 benchmarks complete again on x86_64-apple-darwin12. The result are similar to what
were seen with FSF gcc 4.6.2svn and llvm/dragonegg 3.0 (which was the last release that passed pb05)
http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-October/044091.html.

ps Has an exhaustive effort been made yet to insure that llvm/dragonegg isn't still unnecessarily scalarizing 
the vector code generated by FSF gcc? If that issue were completely solved, llvm/dragonegg might become faster
than vanilla FSF gcc.

FSF gcc 4.7.2 with llvm/dragonegg 3.2 branch

a) de-gfortran47 -msse3 -ffast-math -funroll-loops -O3 %n.f90 -o %n
b) de-gfortran47 -msse3 -ffast-math -funroll-loops -O3 -fplugin-arg-dragonegg-enable-gcc-optzns %n.f90 -o %n
c) gfortran-fsf-4.7 msse3 -ffast-math -funroll-loops -O3 %n.f90 -o %n
