/* sort by: alphabet | popularity */

type OSArch (struct) An OSArch is a pair of GOOS and GOARCH values indicating a platform. Fields (total 2) GOARCH string GOOS string Methods (only one) ( OSArch) String() string Implements (at least 2) OSArch : expvar.Var OSArch : fmt.Stringer

Package-Level Functions (total 13)

func ASanSupported(goos, goarch string) bool ASanSupported reports whether goos/goarch supports the address sanitizer option.

func Broken(goos, goarch string) bool Broken reportsr whether goos/goarch is considered a broken port. (See https://go.dev/wiki/PortingPolicy#broken-ports.)

func BuildModeSupported(compiler, buildmode, goos, goarch string) bool BuildModeSupported reports whether goos/goarch supports the given build mode using the given compiler. There is a copy of this function in cmd/dist/test.go.

func CgoSupported(goos, goarch string) bool CgoSupported reports whether goos/goarch supports cgo.

func DefaultPIE(goos, goarch string, isRace bool) bool DefaultPIE reports whether goos/goarch produces a PIE binary when using the "default" buildmode. On Windows this is affected by -race, so force the caller to pass that in to centralize that choice.

func ExecutableHasDWARF(goos, goarch string) bool ExecutableHasDWARF reports whether the linked executable includes DWARF symbols on goos/goarch.

func FirstClass(goos, goarch string) bool FirstClass reports whether goos/goarch is considered a “first class” port. (See https://go.dev/wiki/PortingPolicy#first-class-ports.)

func FuzzInstrumented(goos, goarch string) bool FuzzInstrumented reports whether fuzzing on goos/goarch uses coverage instrumentation. (FuzzInstrumented implies FuzzSupported.)

func FuzzSupported(goos, goarch string) bool FuzzSupported reports whether goos/goarch supports fuzzing ('go test -fuzz=.').

func InternalLinkPIESupported(goos, goarch string) bool

func MSanSupported(goos, goarch string) bool MSanSupported reports whether goos/goarch supports the memory sanitizer option.

func MustLinkExternal(goos, goarch string, withCgo bool) bool MustLinkExternal reports whether goos/goarch requires external linking with or without cgo dependencies.

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. Race detector only supports 48-bit VMA on arm64. But it will always return true for arm64, because we don't have VMA size information during the compile time.
