llvm dev - Jan 2009 - [LLVMdev] llvm/llvm-gcc-4.2 and xplor-nih

I am happy to report that current llvm/llvm-gcc-4.2 svn
builds all of xplor-nih (a complex mix of c, c++ and fortran)
with  -O3 -fPIC -msse4 -ffast-math. A single fortran file
exposes PR3376 which is triggered by -O3 -ffinite-math-only.
The resulting build of xplor-nih completely passes its testsuite
and compares very well to the same build against gcc trunk for
gcc 4.4 in terms of execution time.

                     gcc 4.4            llvm-gcc-4.2 svn
xplo                68.5205s            64.7649s
xplor-python       152.9726s           154.7344s
xplor-tcl           10.5005s            10.7039s

FYI.
