[LLVMdev] Code Size Benchmark

[Zhongxing Xu]

Hi all,

We did some benchmarks on code size with clang, gcc 4.5, and open64. Clang
performed second in the test. The benchmark is CSiBE. Clang can't compile
the linux kernel (some inline asm not supported) and replaypc (error: use of
unknown builtin '__builtin_next_arg'). The concrete results are attached.
