IRTranslator LLVM IR MI
Instances of this class represent a single low-level machine instruction.

bool getDeprecatedInfo(MCInst &MI, const MCSubtargetInfo &STI, std::string &Info) const
Returns true if a certain instruction is deprecated and if so returns the reason in Info.
Definition: MCInstrInfo.cpp:15
Generic base class for all target subtargets.
const FeatureBitset & getFeatureBits() const
This is an optimization pass for GlobalISel generic memory operations.
