[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.

[LLVMdev] -O4 limitations in llvm/llvm-gcc-4.2 2.5?
...xplor-nih modules. I would assume that the shared
libraries created at -O4 should look like just any other
shared library to MacOS X and that shared modules built
at -O4 should be loadable from programs like python and
tcl that aren't built with -O4, right?

ps Interestingly PR3376 goes latent at -O4.
