Functions

func BuildModeSupported

func BuildModeSupported(compiler, buildmode, goos, goarch string) bool

    BuildModeSupported reports whether goos/goarch supports the given build mode using the given compiler.

    func InternalLinkPIESupported

    func InternalLinkPIESupported(goos, goarch string) bool

    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 MustLinkExternal

      func MustLinkExternal(goos, goarch string) bool

        MustLinkExternal reports whether goos/goarch requires external linking. (This is the opposite of internal/testenv.CanInternalLink. Keep them in sync.)

        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. 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.

          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, ppc64 and ppc64le are both members of the PPC64 family.
