Member Function Documentation

select()

uint64_t llvm::mca::DefaultResourceStrategy::select ( uint64_t  ReadyMask )

overridevirtual

Selects a processor resource unit from a ReadyMask.

Implements llvm::mca::ResourceStrategy.

used()

void llvm::mca::DefaultResourceStrategy::used ( uint64_t  ResourceMask )

overridevirtual

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 from llvm::mca::ResourceStrategy.
