[LLVMdev] Compile a linux kernel with LLVM?

[ymxia at nudt.edu.cn]

Hi,

  I want to check some properties of linux kernel with llvm, but I don't know how to compile a 

linux kernel to an llvm's .bc file. I have let llvm's gcc front-end ignore inline assembly by 

modifying cfrontend/src/gcc/llvm-expand.c, and replace CC/as/ar in the Makefile of the kernel 

with llvm-gcc/llvm-as/llvm-ar. However, the linux's "make" reports errors: "File format not 

recognized" and "not ELF".

  Some people did this before?

Thanks.
