llvm dev - Aug 2011 - [LLVMdev] write IR on file

hi
how can i write IRinstruction on a file.txt? when i use  {for(inst_iterator I =
inst_begin(F), E = inst_end(F); I != E; ++I,count++)  IRcodefile <<
std::basic_ostream(*I) <<"\n" } i get  error.
is there any way that i can write it on file?

Hey Rahil,

try this:

#include "llvm/Support/raw_ostream.h"

Function* f = ...
std::string errorMessage = "";
raw_fd_ostream file("file.txt", errorMessage);
f->print(file, NULL);
file.close();

The class "Module" also has a print-function you can use to dump the 
entire module.
If you want to print additional, custom information (e.g. a comment 
behind each instruction), have a look at the AssemblyAnnotationWriter class.

Best,
Ralf
