LLVM Clang 3.4 SVN Compiler Optimization Level Tests
Phoronix: LLVM Clang 3.4 SVN Compiler Optimization Level Tests
To complement the LLVM 3.4 SVN compiler benchmarks from yesterday that were looking at the impact of using the SLP Vectorizer that's soon to be enabled by default for some optimization levels, here are some more LLVM Clang compiler development benchmarks. This time around are fresh benchmarks of the open-source C/C++ compiler when trying out the different compiler optimization levels, including -O0, -O1, -O2, -Os, -O3, and -Ofast.
Rather ironic you never mention the fact it is really an open-source C/ObjC/C++ compiler and so much more when you cite it. The C++ is important to Apple for I/O Kit [Device Driver stuff and some other stuff], but really the C/ObjC is the main reason for it being built out.
