[LLVMdev] Is cross-compiling for ARM on x86 with llvm/Clang possible?

[Journeyer J. Joh]

Hi,  Gergö

Cross compiling with Clang/llvm is much easier than with llvm-gcc or gcc!

Thank you very much!!
Though I am so much new to llvm that I can't prove your answer right way,
my friend verified your answer.

Thank you very much.

Sincerely
Journeyer

(PS. Sorry I am resending same email because I sent only to you. I want to
say thank you on the mail list.)
