)

Member Function Documentation

◆ getAsStr()

const std::string AAAMDAttributesFunction::getAsStr ( ) const
inlineoverridevirtual

This function should return the "summarized" assumed state as string.

Implements llvm::AbstractAttribute.

Definition at line 452 of file AMDGPUAttributor.cpp.

References ImplicitAttrs, and llvm::raw_string_ostream::str().

◆ initialize()

void AAAMDAttributesFunction::initialize ( Attributor A)
inlineoverridevirtual

Initialize the state with the information in the Attributor A.

This function is called by the Attributor once all abstract attributes have been identified. It can and shall be used for task like:

  • identify existing knowledge in the IR and use it for the "known state"
  • perform any work that is not going to change over time, e.g., determine a subset of the IR, or attributes in-flight, that have to be looked at in the updateImpl method.

Reimplemented from llvm::AbstractAttribute.

Definition at line 328 of file AMDGPUAttributor.cpp.

References F, ImplicitAttrs, and llvm::AMDGPU::isGraphics().

◆ manifest()

ChangeStatus AAAMDAttributesFunction::manifest ( Attributor A)
inlineoverridevirtual

Hook for the Attributor to trigger the manifestation of the information represented by the abstract attribute in the LLVM-IR.

\Return CHANGED if the IR was altered, otherwise UNCHANGED.

Reimplemented from llvm::AbstractAttribute.

Definition at line 439 of file AMDGPUAttributor.cpp.

References llvm::Attribute::get(), ImplicitAttrs, and llvm::IRAttributeManifest::manifestAttrs().

◆ trackStatistics()

void AAAMDAttributesFunction::trackStatistics ( ) const
inlineoverridevirtual

See AbstractAttribute::trackStatistics()

Implements llvm::AbstractAttribute.

Definition at line 463 of file AMDGPUAttributor.cpp.

◆ updateImpl()

ChangeStatus AAAMDAttributesFunction::updateImpl ( Attributor A)
inlineoverridevirtual

The actual update/transfer function which has to be implemented by the derived classes.

If it is called, the environment has changed and we have to determine if the current information is still valid or adjust it otherwise.

\Return CHANGED if the internal state changed, otherwise UNCHANGED.

Implements llvm::AbstractAttribute.
