func ARM64RegisterArrangement(reg int16, name, arng string) (int64, error)
ARM64RegisterArrangement constructs an ARM64 vector register arrangement.
func ARM64RegisterExtension(a *obj.Addr, ext string, reg, num int16, isAmount, isIndex bool) error
ARM64RegisterExtension constructs an ARM64 register with extension or arrangement.
func ARM64RegisterListOffset(firstReg, regCnt int, arrangement int64) (int64, error)
ARM64RegisterListOffset generates offset encoding according to AArch64 specification.
func ARM64RegisterShift(reg, op, count int16) (int64, error)
ARM64RegisterShift constructs an ARM64 register with shift operation.
func ARM64Suffix(prog *obj.Prog, cond string) bool
ARM64Suffix handles the special suffix for the ARM64. It returns a boolean to indicate success; failure means cond was unrecognized.
func ARMConditionCodes(prog *obj.Prog, cond string) bool
ARMConditionCodes handles the special condition code situation for the ARM. It returns a boolean to indicate success; failure means cond was unrecognized.
func ARMMRCOffset(op obj.As, cond string, x0, x1, x2, x3, x4, x5 int64) (offset int64, op0 obj.As, ok bool)
ARMMRCOffset implements the peculiar encoding of the MRC and MCR instructions. The difference between MRC and MCR is represented by a bit high in the word, not in the usual way by the opcode itself. Asm must use AMRC for both instructions, so we return the opcode for MRC so that asm doesn't need to import obj/arm.
func GetARM64SpecialOperand(name string) arm64.SpecialOperand
GetARM64SpecialOperand returns the internal representation of a special operand.
func IsARM64ADR(op obj.As) bool
IsARM64ADR reports whether the op (as defined by an arm64.A* constant) is one of the comparison instructions that require special handling.
func IsARM64CASP(op obj.As) bool
IsARM64CASP reports whether the op (as defined by an arm64.A* constant) is one of the CASP-like instructions, and its 2nd destination is a register pair that require special handling.
func IsARM64CMP(op obj.As) bool
IsARM64CMP reports whether the op (as defined by an arm64.A* constant) is one of the comparison instructions that require special handling.

IsARMCMP reports whether the op (as defined by an arm.A* constant) is one of the comparison instructions that require special handling.
func IsARMFloatCmp(op obj.As) bool
IsARMFloatCmp reports whether the op is a floating comparison instruction.
func IsARMMRC(op obj.As) bool
IsARMMRC reports whether the op (as defined by an arm.A* constant) is MRC or MCR.
func IsARMMULA(op obj.As) bool
IsARMMULA reports whether the op (as defined by an arm.A* constant) is MULA, MULS, MMULA, MMULS, MULABB, MULAWB or MULAWT, the 4-operand instructions.
func IsARMSTREX(op obj.As) bool
IsARMSTREX reports whether the op (as defined by an arm.A* constant) is one of the STREX-like instructions that require special handling.
func IsLoong64AMO(op obj.As) bool

IsMIPSCMP reports whether the op (as defined by an mips.A* constant) is one of the CMP instructions that require special handling.
func IsMIPSMUL(op obj.As) bool
IsMIPSMUL reports whether the op (as defined by an mips.A* constant) is one of the MUL/DIV/REM/MADD/MSUB instructions that require special handling.
func IsPPC64CMP(op obj.As) bool
IsPPC64CMP reports whether the op (as defined by an ppc64.A* constant) is one of the CMP instructions that require special handling.
func IsPPC64NEG(op obj.As) bool
IsPPC64NEG reports whether the op (as defined by an ppc64.A* constant) is one of the NEG-like instructions that require special handling.

ParseARMCondition parses the conditions attached to an ARM instruction. The input is a single string consisting of period-separated condition codes, such as ".P.W". An initial period is ignored.
