Overview

package goarch contains GOARCH-specific constants.

Package files

goarch.go goarch_amd64.go zgoarch_amd64.go

Constants

BigEndian reports whether the architecture is big-endian.

const BigEndian = IsArmbe|IsArm64be|IsMips|IsMips64|IsPpc|IsPpc64|IsS390|IsS390x|IsSparc|IsSparc64 == 1

DefaultPhysPageSize is the default physical page size.

const DefaultPhysPageSize = _DefaultPhysPageSize

const GOARCH = `amd64`

Int64Align is the required alignment for a 64-bit integer (4 on 32-bit systems, 8 on 64-bit).

const Int64Align = PtrSize

const Is386 = 0

const IsAmd64 = 1

const IsAmd64p32 = 0

const IsArm = 0

const IsArm64 = 0

const IsArm64be = 0

const IsArmbe = 0

const IsLoong64 = 0

const IsMips = 0

const IsMips64 = 0

const IsMips64le = 0

const IsMips64p32 = 0

const IsMips64p32le = 0

const IsMipsle = 0

const IsPpc = 0

const IsPpc64 = 0

const IsPpc64le = 0

const IsRiscv = 0

const IsRiscv64 = 0

const IsS390 = 0

const IsS390x = 0

const IsSparc = 0

const IsSparc64 = 0

const IsWasm = 0

MinFrameSize is the size of the system-reserved words at the bottom of a frame (just above the architectural stack pointer). It is zero on x86 and PtrSize on most non-x86 (LR-based) systems. On PowerPC it is larger, to cover three more reserved words: the compiler word, the link editor word, and the TOC save word.

const MinFrameSize = _MinFrameSize

PCQuantum is the minimal unit for a program counter (1 on x86, 4 on most other systems). The various PC tables record PC deltas pre-divided by PCQuantum.

const PCQuantum = _PCQuantum

PtrSize is the size of a pointer in bytes - unsafe.Sizeof(uintptr(0)) but as an ideal constant. It is also the size of the machine's native word size (that is, 4 on 32-bit systems, 8 on 64-bit).

const PtrSize = 4 << (^uintptr(0) >> 63)

StackAlign is the required alignment of the SP register. The stack must be at least word aligned, but some architectures require more.

const StackAlign = _StackAlign

type ArchFamilyType

type ArchFamilyType int

const (
+    AMD64 ArchFamilyType = iota
+    ARM
+    ARM64
+    I386
+    LOONG64
+    MIPS
+    MIPS64
+    PPC64
+    RISCV64
+    S390X
+    WASM
+)

ArchFamily is the architecture family (AMD64, ARM, ...)

const ArchFamily ArchFamilyType = _ArchFamily
