getPassName - Return a nice clean name for a pass.

This usually implemented in terms of the name that is registered by one of the Registration templates, but can be overloaded directly.

Reimplemented from llvm::Pass.

Definition at line 105 of file RegionPass.h.

◆ runOnFunction()

bool RGPassManager::runOnFunction ( Function & F) overridevirtual

Execute all of the passes scheduled for execution.

run - Execute all of the passes scheduled for execution.

Returns

True if any of the passes modifies the function.

Keep track of whether any of the passes modifies the function, and if so, return true.

Implements llvm::FunctionPass.
