func ARM64RegisterArrangement(reg int16, name, arng string) (int64, error)
ARM64RegisterArrangement parses an ARM64 vector register arrangement.
func ARM64RegisterExtension(a *obj.Addr, ext string, reg, num int16, isAmount, isIndex bool) error
ARM64RegisterExtension parses 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 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 IsARM64CMP(op obj.As) bool
IsARM64CMP reports whether the op (as defined by an arm.A* constant) is one of the comparison instructions that require special handling.
func IsARM64STLXR(op obj.As) bool
IsARM64STLXR reports whether the op (as defined by an arm64.A* constant) is one of the STLXR-like instructions that require special handling.
func IsARM64TBL(op obj.As) bool
IsARM64TBL reports whether the op (as defined by an arm64.A* constant) is one of the table lookup instructions that require special handling.
func IsARMBFX(op obj.As) bool
IsARMBFX reports whether the op (as defined by an arm.A* constant) is one the BFX-like instructions which are in the form of "op $width, $LSB, (Reg,) Reg".
func IsARMCMP(op obj.As) bool
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 IsMIPSCMP(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 IsPPC64ISEL(op obj.As) bool
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.
func IsPPC64RLD(op obj.As) bool
IsPPC64RLD reports whether the op (as defined by an ppc64.A* constant) is one of the RLD-like instructions that require special handling. The FMADD-like instructions behave similarly.
func IsRISCV64AMO(op obj.As) bool
IsRISCV64AMO reports whether the op (as defined by a riscv.A* constant) is one of the AMO instructions that requires special handling.
func ParseARMCondition(cond string) (uint8, bool)
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.
Arch wraps the link architecture object with more architecture-specific information.
type Arch struct {

Instructions map[string]obj.As
// Map of register names to enumeration.
Register map[string]int16
// Table of register prefix names. These are things like R for R(0) and SPR for SPR(268).
RegisterPrefix map[string]bool
// RegisterNumber converts R(10) into arm.REG_R10.
RegisterNumber func(string, int16) (int16, bool)
// Instruction is a jump.
IsJump func(word string) bool

func Set(GOARCH string) *Arch
Set configures the architecture specified by GOARCH and returns its representation. It returns nil if GOARCH is not recognized.
