Member Function Documentation

◆ createPassConfig()

TargetPassConfig * LanaiTargetMachine::createPassConfig ( PassManagerBase PM)
overridevirtual

Create a pass configuration object to be used by addPassToEmitX methods for generating a pipeline of CodeGen passes.

createPassConfig - Create a pass configuration object to be used by addPassToEmitX methods for generating a pipeline of CodeGen passes.

Targets may override this to extend TargetPassConfig.

◆ getSubtargetImpl()

const LanaiSubtarget* llvm::LanaiTargetMachine::getSubtargetImpl ( const llvm::Function ) const
inlineoverridevirtual

Virtual method implemented by subclasses that returns a reference to that target's TargetSubtargetInfo-derived member variable.

Reimplemented from llvm::TargetMachine.

Definition at line 37 of file LanaiTargetMachine.h.

◆ getTargetTransformInfo()

TargetTransformInfo LanaiTargetMachine::getTargetTransformInfo ( const Function F)
overridevirtual

Get a TargetTransformInfo implementation for the target.

The TTI returned uses the common code generator to answer queries about the IR.

Reimplemented from llvm::LLVMTargetMachine.

◆ isMachineVerifierClean()

bool llvm::LanaiTargetMachine::isMachineVerifierClean ( ) const
inlineoverridevirtual

Returns true if the target is expected to pass all machine verifier checks.

This is a stopgap measure to fix targets one by one. We will remove this at some point and always enable the verifier when EXPENSIVE_CHECKS is enabled.

Reimplemented from llvm::LLVMTargetMachine.
