Functions

func CollectUnused

func CollectUnused(desc *ast.Description, target *targets.Target, eh ast.ErrorHandler) ([]ast.Node, error)

func DeserializeConsts

func DeserializeConsts(data []byte, file string, eh ast.ErrorHandler) map[string]uint64

func DeserializeConstsGlob

func DeserializeConstsGlob(glob string, eh ast.ErrorHandler) map[string]uint64

func ExtractConsts

func ExtractConsts(desc *ast.Description, target *targets.Target, eh ast.ErrorHandler) map[string]*ConstInfo

func FabricateSyscallConsts

func FabricateSyscallConsts(target *targets.Target, constInfo map[string]*ConstInfo, consts map[string]uint64)

FabricateSyscallConsts adds syscall number constants to consts map. Used for test OS to not bother specifying consts for all syscalls.

func Fuzz

func Fuzz(data []byte) int

func SerializeConsts

func SerializeConsts(consts map[string]uint64, undeclared map[string]bool) []byte

Types

type ConstInfo

type ConstInfo struct {
	Consts   []string
	Includes []string
	Incdirs  []string
	Defines  map[string]string
}

type Prog

type Prog struct {
	Resources []*prog.ResourceDesc
	Syscalls  []*prog.Syscall
	Types     []prog.Type
	// Set of unsupported syscalls/flags.
	Unsupported map[string]bool
	// contains filtered or unexported fields
}

Prog is description compilation result.

func Compile

func Compile(desc *ast.Description, consts map[string]uint64, target *targets.Target, eh ast.ErrorHandler) *Prog

Compile compiles sys description.
