LLVM/Clang 3.2 SVN Compiler Performance

Corei7-avx improvements in LLVM/Clang 3.2 led to slightly better numbers for the C-Ray ray-tracing benchmark.

It was a similar story for Smallpt too.

Audio encoding with FLAC was flat.

There wasn't much change out PostgreSQL built by LLVM/Clang 3.2.

With the tests carried out thus far of LLVM/Clang 3.2 from the Intel Core i7 Sandy Bridge Extreme Edition processor, there doesn't appear to be much change in performance compared to the LLVM/Clang 3.1 stable release from earlier this year. There were some performance regressions, but they seem to be mainly isolated to the GraphicsMagick program. Further compiler benchmarks -- including from other x86 and ARM hardware -- will be carried out as the LLVM/Clang 3.2 release approaches in December.
