LLVM Clang 3.8 Compiler Performance Benchmarks
With LLVM 3.8 scheduled to be released this week, here are benchmarks of the LLVM Clang 3.8 compiler code compared to Clang 3.7 and Clang 3.6 for a variety of C/C++ performance benchmarks.
On an Intel Xeon E5-2687W v3 Haswell workstation running Ubuntu 16.04 x86_64 I ran some fresh benchmarks of Clang 3.6, Clang 3.7, and Clang 3.8 recently when they were all built in the same manner on this system. The CFLAGS/CXXFLAGS were obviously maintained as well throughout testing. All of this Clang compiler benchmarking was done in a fully-automated manner using the open-source Phoronix Test Suite benchmarking software.
On the following pages are the results and coming up shortly I will have a LLVM Clang 3.8 vs. GCC 6 compiler comparison on Phoronix.
