A few weeks ago there were benchmarks of GCC, LLVM-GCC,
DragonEgg, and Clang. In this compiler performance comparison the
releases of GCC 4.2, 4.3, 4.4, 4.5, and a 4.6 development snapshot were
benchmarked. On the LLVM side there was LLVM-GCC 4.2, DragonEgg with GCC
4.5 and LLVM 2.8, and then Clang with LLVM 2.8. This combination of
eight open-source compilers were tested on three distinct Intel and AMD
systems (even a 12-thread Core i7 Gulftown), but all of which were
64-bit capable and contained relatively high-end processors from their
respective series. To complement this earlier article, available now are
some new GCC/LLVM benchmarks but this time an older Intel Atom CPU was
used to look at the 32-bit compiler performance on a slower, low-power
netbook.
