llvm dev - Nov 2012 - [LLVMdev] Mips instructions using llvm?

Hi Eli,
What do you mean by "kind of vague" ? So does not guarantee to
generate correct instructions ?
I just tried what you said but getting following error ? Any ideas ? What I did
is clang hello.c -S -target mips-unknown-linux
Error: In file included from hello.c:1In file included from
/usr/include/stdio.h:28/usr/include/features.h:323:10 fatak error
'bits/predefs.h' file not found.

"Generate MIPS instructions" is kind of vague, but something like
"clang myfile.c -S -target mips-unknown-linux" will make clang
generate MIPS assembly.

Your question is vague.  Generally, you get better answers if you ask better
questions.

This sounds like you are using headers that do not support MIPS.

Sorry, I didn't mean to be rude. My question is does that
mean institution generated may not guarantee what the "instructions"
mean to be ?

 So can I fix this? In my hello.c code I have only stdio.h header file.
