Types

type Description

type Description struct {
	// The function is known to be pure
	Pure bool
	// The function is known to be a stub
	Stub bool
	// The function is known to never return (panics notwithstanding)
	Infinite bool
	// Variable ranges
	Ranges vrp.Ranges
	Loops  []Loop
	// Function returns an error as its last argument, but it is
	// always nil
	NilError            bool
	ConcreteReturnTypes []*types.Tuple
}

type Descriptions

type Descriptions struct {
	CallGraph *callgraph.Graph
	// contains filtered or unexported fields
}

func NewDescriptions

func NewDescriptions(prog *ssa.Program) *Descriptions

func (*Descriptions) Get

func (d *Descriptions) Get(fn *ssa.Function) Description

func (*Descriptions) IsPure

func (d *Descriptions) IsPure(fn *ssa.Function) bool

func (*Descriptions) IsStub

func (d *Descriptions) IsStub(fn *ssa.Function) bool

IsStub reports whether a function is a stub. A function is considered a stub if it has no instructions or exactly one instruction, which must be either returning only constant values or a panic.
