Member Function Documentation

◆ add()

void llvm::legacy::PassManagerImpl::add ( Pass P)

Add a pass to the queue of passes to run.

This passes ownership of the Pass to the PassManager. When the PassManager is destroyed, the pass will be destroyed as well, so there is no need to delete the pass. This may even destroy the pass right away if it is found to be redundant. This implies that all passes MUST be allocated with 'new'.
