llvm dev - Jan 2012 - [LLVMdev] Convert .ll file to .c file

Hi,

    I wanted to convert .ll file to .c file (for the sake of debugging the
c file). I used the command "llc" with "-march=c" option.
But i'm getting
the below error.

         *llc: error: invalid target 'c'*
*
*
My script file code for converting it is:

llvm-as -f module.ll
opt -o=module.bc module.bc
llvm-dis module.bc
llc -f -march=c module.bc
#gcc  module.cbe.c -lstdc++

What i need to do to get the 'c' file generated. I build LLVM using
'*enable-targets
= x86*' . Can i use '*enable-targets = x86,c*' to clear the error?

Thanks in advance......
*

You don't need the llvm-dis step (unless you want the module.ll file for 
some other reason).

I think you're looking for configure --enable-targets=x86,cbe .

Hi Nick,

     I need the module.ll file. Now how can i configure LLVM to enable
"c"
target? Is it that i need to build from the scratch? Is there any way to
enable 'c' target also?
