[LLVMdev] llvm for ARM

[Christopher Lamb]

Hi Amit,

I believe what you need to do is compile llvm-gcc as a cross compiler  
in much the same way that you would for normal gcc. The LLVM Target  
library contains all of the back ends by default so I believe  
retargeting the front end is all you've got to do.
