llvm dev - Sep 2008 - [LLVMdev] Can I use x-86 front end to generate .bc file for another architecture

Hi.

I successfully build llvm backend2.3 for sparc/solaris, but  failed to build
LLVM front end of Sparc/Solaris.

 

I'm wondering if there is any option I can use with X-86 version of llvm-gcc
front end to generate .bc file for sparc backend. Suppose I have the include
files.

 

 

Thanks.

Sure you can, but the code won't work in general.  See the other  
thread about arch portability and also:

What's the option of llvm-gcc to use then?

Is it just to specify -I or -B like gcc does?
