Detailed Description

FPPassManager manages BBPassManagers and FunctionPasses.

It batches all function passes and basic block pass managers together and sequence them to process one function at a time before processing next function.

◆ runOnFunction()

bool FPPassManager::runOnFunction ( Function F)

run - Execute all of the passes scheduled for execution.

Execute all of the passes scheduled for execution by invoking runOnFunction method.

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