Functions ¶

func AnySideEffects ¶

func AnySideEffects(n ir.Node) bool

AnySideEffects reports whether n contains any operations that could have observable side effects.

func StaticLoc ¶

func StaticLoc(n ir.Node) (name *ir.Name, offset int64, ok bool)

StaticLoc returns the static address of n, if n has one, or else nil.

func StaticName ¶

func StaticName(t *types.Type) *ir.Name

StaticName returns a name backed by a (writable) static data symbol. Use readonlystaticname for read-only node.

Types ¶

type Entry ¶

type Entry struct {
	Xoffset int64   // struct, array only
	Expr    ir.Node // bytes of run-time computed expressions
}

type Plan ¶

type Plan struct {
	E []Entry
}

type Schedule ¶

type Schedule struct {
	// Out is the ordered list of dynamic initialization
	// statements.
	Out []ir.Node

	Plans map[ir.Node]*Plan
	Temps map[ir.Node]*ir.Name
}

An Schedule is used to decompose assignment statements into static and dynamic initialization parts. Static initializations are handled by populating variables' linker symbol data, while dynamic initializations are accumulated to be executed in order.

func (*Schedule) StaticAssign ¶

func (s *Schedule) StaticAssign(l *ir.Name, loff int64, r ir.Node, typ *types.Type) bool

func (*Schedule) StaticInit ¶

func (s *Schedule) StaticInit(n ir.Node)

StaticInit adds an initialization statement n to the schedule.
