Version 4.6 of GCC was released over the weekend with a
multitude of improvements and version 2.9 of the Low-Level Virtual
Machine is due out in early April with its share of improvements. How
though do these two leading open-source compilers compare? In this
article we are providing benchmarks of GCC 4.5.2, GCC 4.6.0, DragonEgg
with LLVM 2.9, and Clang with LLVM 2.9 across five distinct AMD / Intel
systems to see how the compiler performance compares.
