Functions

func MSanSupported 

func MSanSupported(goos, goarch string) bool

MSanSupported reports whether goos/goarch supports the memory sanitizer option. There is a copy of this function in cmd/dist/test.go.

func RaceDetectorSupported 

func RaceDetectorSupported(goos, goarch string) bool

RaceDetectorSupported reports whether goos/goarch supports the race detector. There is a copy of this function in cmd/dist/test.go.

Types

type Arch 

type Arch struct {
	Name   string
	Family ArchFamily

	ByteOrder binary.ByteOrder

	// PtrSize is the size in bytes of pointers and the
	// predeclared "int", "uint", and "uintptr" types.
	PtrSize int

	// RegSize is the size in bytes of general purpose registers.
	RegSize int

	// MinLC is the minimum length of an instruction code.
	MinLC int
}

Arch represents an individual architecture.

func (*Arch) InFamily 

func (a *Arch) InFamily(xs ...ArchFamily) bool

InFamily reports whether a is a member of any of the specified architecture families.

type ArchFamily 

type ArchFamily byte

ArchFamily represents a family of one or more related architectures. For example, amd64 and amd64p32 are both members of the AMD64 family, and ppc64 and ppc64le are both members of the PPC64 family.
