New GCC releases comparison and comparison of GCC4.4 and LLVM2.5 on SPEC2000


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.
