Below are the results for the Polyhedron 2005 benchmarks compiled with
llvm/compiler-rt/dragonegg 3.3svn at r182439 against current
FSF gcc 4.7.3svn and 4.8.1svn. The only major bug remaining in the dragonegg
3.3svn support for gcc 4.8.x is http://llvm.org/bugs/show_bug.cgi?id=15980
which results in unresolved symbols for _iround and _iroundf in the aermod and
rnflow testcases. Note that this skews the geometric mean
of the run time to much higher values.

Duncan,
With r182593, the dragonegg 3.3 branch now completely passes the Polyhedron
2005 benchmarks
using the FSF gcc 4.8.1svn compiler. Thanks.

Hi Jack, do the results improve significantly with the attached patch applied? If enables IR level fast math optimizations and the loop vectorizer. Note that some loop vectorizations only kick in if fast-math is enabled too. Best wishes, Duncan.

There is a small improvement in the dragonegg results (without -fplugin-arg-dragonegg-enable-gcc-optzns) in RC3. I assume we still only have partial coverage of all of the -ffast-math optimizations performed by FSF gcc in llvm's fast-math support, correct?

As rc3 hasn't been tagged yet, I assume you used latest 3.3svn?> There is a small improvement in the dragonegg results (without -fplugin-arg-dragonegg-enable-gcc-optzns) in RC3. I assume > we still only have partial coverage of all of the -ffast-math optimizations performed by FSF gcc in llvm's fast-math > support, correct?These results are very disappointing, I was hoping to see a big improvement somewhere instead of no real improvement anywhere (except for gas_dyn) or a regression (eg: mdbx). I think LLVM now has a reasonable array of fast-math optimizations. I will try to find time to poke at gas_dyn and induct: since turning on gcc's optimizations there halve the run-time, LLVM's IR optimizers are clearly missing something important.
