Only in a few benchmarks were the C/C++ benchmarks interested in the way of LLVM Clang 3.3 vs. LLVM Clang 3.4 SVN for the Intel Core i7 4750HQ "Haswell" processor found in the System76 Galago UltraPro. The CFLAGS/CXXFLAGS were set to "-03 -march=native" during testing for this CPU with AVX 2.0 capabilities, etc.
All of the benchmark results in full -- along with the complete system details, logs, etc -- can be found on OpenBenchmarking.org via 1309182-SO-LLVMCLANG36. Embedded below are just some of the more interesting Clang compiler benchmark results.
More benchmarks of the LLVM Clang C/C++ compiler -- along with comparative GCC tests -- will come as the new releases approach and as we discover new and interesting workloads and have access to new hardware platforms.
