llvm-dis crtbegin.bc

Hi,

llvm-gcc-4.2 (trunk) built with llvm-2.2 (trunk) hangs in an endless loop
compiling gcc/crtstuff.c.

The llvm-dis (crtbegin.ll) output is joined, following Duncan Sands's
instructions:

« llc crtbegin.bc » hangs in an endless loop in the same way than gcc
bootstrap build.
