A few people asked me to do a new comparison of GCC releases and LLVM as
the new GCC release and LLVM were out recently.
You can find the comparison on http://vmakarov.fedorapeople.org/spec/
The comparison for x86 (32-bit mode) was done on Pentium4 and for
x86_64 (64-bit mode) on Core I7.
Some changes in the performance were big since GCC 3.2 and it is
sometimes hard to see small changes on the posted graphs. Therefore I
put original tables used to generate the graphs.
