LLVM/Clang 3.2 SVN Compiler Performance
Phoronix: LLVM/Clang 3.2 SVN Compiler Performance
With LLVM 3.2 set for release in mid-December, the time to benchmark this next major compiler infrastructure release paired with the Clang C/C++ compiler is approaching. Well, that time has already come; up this weekend are some benchmarks of the Intel Core i7 3960X "Sandy Bridge Extreme Edition" on Ubuntu 12.04 when comparing LLVM/Clang 3.1 to their latest SVN development code for LLVM/Clang 3.2 as of this week.
Compilers have other important qualities beyond generated code.
What really needs to be tested is the compliancy with C++11. C++11 and a compilers ability to support it, will become very important very quickly. Of course the compilers need to generate good code while supporting C++11 and that should be tested, but significance here isn't that great in comparison.
To put it another way, testing really should be helping people use and transition to the new conventions. As can be seen in this report generated code isn't changing significantly so why bother fretting over a few percentage here and there.
