Bug: clang-cc -cfg-view

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

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:
End of search list.

AFAIK, -cfg-dump only works in -analyze mode.
