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.

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

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
