[LLVMdev] LLVM 2.9 Fails to Compile some CPU2006 Benchmarks on X86

[Duncan Sands]

Hi Ghassan, llvm-gcc is dead: the 2.9 release was the last release, so it is
unlikely that anyone is going to fix problems with it.  Please use clang or
dragonegg instead.  The development version of dragonegg correctly compiled all
of SPEC CPU 2006 last time I checked.

Ciao, Duncan.
