Method Overview

Methods

llvm::MachineInstr* CloneMachineInstr(

true if no problems were found.

void viewCFG() const

Description

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.

Declared at: llvm/include/llvm/CodeGen/MachineFunction.h:614

void viewCFGOnly() const

Description

viewCFGOnly - This function is meant for use from the debugger. It works just like viewCFG, but it does not include the contents of basic blocks into the nodes, just the label. If you are only interested in the CFG this can make the graph smaller.

Declared at: llvm/include/llvm/CodeGen/MachineFunction.h:621
