MCRegisterInfo base class - We assume that the target defines a static array of MCRegisterDesc object...
Generic base class for all target subtargets.
bool writeNopData(raw_ostream &OS, uint64_t Count, const MCSubtargetInfo *STI) const override
WriteNopData - Write an (optimal) nop sequence of Count bytes to the given output.
MCFixupKindInfo getFixupKindInfo(MCFixupKind Kind) const override
Get information on a fixup kind.
std::optional< MCFixupKind > getFixupKind(StringRef Name) const override
Map a relocation name used in .reloc to a fixup kind.
void applyFixup(const MCFragment &, const MCFixup &, const MCValue &Target, uint8_t *Data, uint64_t Value, bool IsResolved) override
