Member Function Documentation

select()

virtual uint64_t llvm::mca::ResourceStrategy::select ( uint64_t  ReadyMask )

pure virtual

Selects a processor resource unit from a ReadyMask.

Implemented in llvm::mca::DefaultResourceStrategy.

used()

virtual void llvm::mca::ResourceStrategy::used ( uint64_t  ResourceMask )

inlinevirtual

Called by the ResourceManager when a processor resource group, or a processor resource with multiple units has become unavailable.

The default strategy uses this information to bias its selection logic.

Reimplemented in llvm::mca::DefaultResourceStrategy.
