Declared at: llvm/include/llvm/MCA/HardwareUnits/ResourceManager.h:68

Inherits from: ResourceStrategy

Method Overview

• public DefaultResourceStrategy(uint64_t UnitMask)
• public uint64_t select(uint64_t ReadyMask)
• public void used(uint64_t Mask)

Methods

¶DefaultResourceStrategy(uint64_t UnitMask)

Declared at: llvm/include/llvm/MCA/HardwareUnits/ResourceManager.h:121

Parameters

uint64_t UnitMask

¶uint64_t select(uint64_t ReadyMask)

Description

Selects a processor resource unit from a ReadyMask.

Declared at: llvm/include/llvm/MCA/HardwareUnits/ResourceManager.h:126

Parameters

uint64_t ReadyMask

¶void used(uint64_t Mask)

Description

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.

Declared at: llvm/include/llvm/MCA/HardwareUnits/ResourceManager.h:127

Parameters

uint64_t Mask

¶virtual ~DefaultResourceStrategy()
