[LLVMdev] build errors while cross compiling llvm-gcc for ARM

[Sanjeev chugh]

Thanks, last doubt :)

But I wanted to say is using these binutils I have built a llvm compiler for
our ARM target.

Now our libraries which are either compiled with native ARM or with this
llvm compiler gives same performance numbers. However this only llvm
compiler if compared with x86 compiler gives huge performance gain.

Any idea why this might be happening ?
