CSKYSubtarget & initializeSubtargetDependencies(const Triple &TT, StringRef CPU, StringRef TuneCPU, StringRef FS)

Initializes using the passed in CPU and feature strings so that we can use initializer lists for subt...

CSKYSubtarget(const Triple &TT, StringRef CPU, StringRef TuneCPU, StringRef FS, const TargetMachine &TM)

const CSKYTargetLowering * getTargetLowering() const override

StringRef - Represent a constant reference to a string, i.e.

constexpr bool empty() const

empty - Check if the string is empty.

const TargetMachine & getTargetMachine() const

Primary interface to the complete machine description for the target machine.

FloatABI::ABIType FloatABIType

FloatABIType - This setting is set by -float-abi=xxx option is specfied on the command line.

Triple - Helper class for working with autoconf configuration names.

This is an optimization pass for GlobalISel generic memory operations.
