[LLVMdev] viewCFGOnly() function

[David Stuttard]

You can call the function from your program OR the debugger. The 
comments simply inform you that it is quite handy to be able to call the 
function from a debugger (such as gdb).

To call the function in you code simply add a line such as:
F->viewCFGOnly();
Where F is an appropriate variable eg. a MachineFunction pointer

If you are using gdb then you can do the following:
call F->viewCFGOnly()

from a point where F is live.
