◆ viewCFG()

void MachineFunction::viewCFG ( ) const

viewCFG - This function is meant for use from the debugger.

You can just say 'call F->viewCFG()' and a ghostview window should pop up from the program, displaying the CFG of the current function with the code for each basic block inside. This depends on there being a 'dot' and 'gv' program in your path.

◆ viewCFGOnly()

viewCFGOnly - This function is meant for use from the debugger.
