void relaxInstruction(MCInst &Inst, const MCSubtargetInfo &STI) const override
Relax the instruction in the given fragment to the next wider instruction.
std::optional< MCFixupKind > getFixupKind(StringRef Name) const override
Map a relocation name used in .reloc to a fixup kind.
bool shouldForceRelocation(const MCAssembler &Asm, const MCFixup &Fixup, const MCValue &Target) override
Hook to check if a relocation is needed for some target specific reason.

bool fixupNeedsRelaxation(const MCFixup &Fixup, uint64_t Value, const MCRelaxableFragment *DF, const MCAsmLayout &Layout) const override
Simple predicate for targets where !Resolved implies requiring relaxation.

~LoongArchAsmBackend() override
Generic interface to target specific assembler backends.
Encapsulates the layout of an assembly file at a particular point in time.
Encode information on a single operation to perform on a byte sequence (e.g., an encoded instruction)...
Instances of this class represent a single low-level machine instruction.
A relaxable fragment holds on to its MCInst, since it may need to be relaxed during the assembler lay...
Generic base class for all target subtargets.
This represents an "assembler immediate".
MutableArrayRef - Represent a mutable reference to an array (0 or more elements consecutively in memo...
StringRef - Represent a constant reference to a string, i.e.
Target - Wrapper for Target specific information.
LLVM Value Representation.
This class implements an extremely fast bulk output stream that can only output to a stream.
This is an optimization pass for GlobalISel generic memory operations.
MCFixupKind
Extensible enumeration to represent the type of a fixup.
Target independent information on a fixup kind.
