Detailed Description

This class represents a pass manager that runs passes on either a specific operation type, or any isolated operation.

This pass manager can not be run on an operation directly, but must be run either as part of a top-level PassManager(e.g. when constructed via nest calls), or dynamically within a pass by using the Pass::runPipeline API.

Member Typedef Documentation

◆ const_pass_iterator

using mlir::OpPassManager::const_pass_iterator = llvm::pointee_iterator<ArrayRef<std::unique_ptr<Pass> >::const_iterator>

Definition at line 82 of file PassManager.h.

◆ pass_iterator

Member Enumeration Documentation

◆ Nesting

This enum represents the nesting behavior of the pass manager.

Enumerator
Implicit 

Implicit nesting behavior.

This allows for adding passes operating on operations different from this pass manager, in which case a new pass manager is implicitly nested for the operation type of the new pass.

Explicit 

Explicit nesting behavior.

This requires that any passes added to this pass manager support its operation type.

Definition at line 50 of file PassManager.h.
