[LLVMdev] New llvmgcc4 snapshot

[Marco Matthies]

Hi,

i tried compiling llvmgcc4 on x86_64-linux. The two changes i needed to 
apply to llvm and llvmgcc4 are attached. Those two patches tell llvmgcc4 
to use the x86 code-generator for x86_64 and give x86_64-* targets a 
score of 10 for the x86 backend when trying to find appropriate backends.

Now i'm getting stuck during the compile when an assertion is triggered:

I know x86_64 is unsupported, but does anybody have an idea if i'm doing 
something wrong or is this a bug?

Any help is greatly appreciated,

Marco
