Overview

package goarch contains GOARCH-specific constants.

Constants

BigEndian reports whether the architecture is big-endian.

const DefaultPhysPageSize = _DefaultPhysPageSize

DefaultPhysPageSize is the default physical page size.

const GOARCH = `amd64`

const Int64Align = PtrSize

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

const MinFrameSize = _MinFrameSize

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 PCQuantum = _PCQuantum

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

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).

View Source
const StackAlign = _StackAlign

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