[cfe-dev] Bug: clang-cc -cfg-view

[Micky J]

Hi,
After checking out and building llvm ,
running clang-cc on the program file.c
simply does not produce any results.

file.c:
int main (int argc, char* argv[]) {


  return 0;
}


Here is the run session:

$ clang-cc -cfg-dump -v file.c
clang-cc version 1.1 based upon llvm 2.7svn hosted on i386-pc-linux-gnu
ignoring nonexistent directory "/System/Library/Frameworks"
ignoring nonexistent directory "/Library/Frameworks"
#include "..." search starts here:
#include <...> search starts here:
 /home/milj/downloads/src/llvm/llvm/Debug/lib/clang/1.1/include
 /usr/local/include
 /usr/include
End of search list.
----------------------------------

The -ast-dump and -ast-view options work perfectly, but the -cfg-dump and
-cfg-view options do not.
Does someone have any recommendations on how to get -cfg-dump and -cfg-view
to work with clang-cc or
for some other visualization alternatives of llvm code CFGs?

Regards!
Micky
