Some Fresh Clang Optimization Benchmarks

As some extra benchmarks to toss out there this weekend are some Clang 3.8 SVN compiler benchmarks when trying out different optimization levels.

LLVM Clang 3.8 SVN was tested as of a few days ago atop an Ubuntu 15.10 x86_64 system. The Clang 3.8 tests were done when the CFLAGS/CXXFLAGS set separately to -O3 -march=native, -O3, -O2, -O1- and -O0. These numbers are just being put out there for reference purposes and using just a random selection of tests... Basically there was free time on one of the test systems and I was just running some extra benchmarks for testing some different code paths of the Phoronix Test Suite prior to its Hammerfest release.


So take the results as you wish and you can find all of these LLVM Clang 3.8 SVN benchmarks via this OpenBenchmarking.org result file while embedded below is just a sampling of the more interesting results.
