func InitCoverage()
InitCoverage loads the definitions for routines called by code coverage instrumentation (similar to InitRuntime above).

func Lookdot(n *ir.SelectorExpr, t *types.Type, dostrcmp int) *types.Field
Lookdot looks up field or method n.Sel in the type t and returns the matching field. It transforms the op of node n to ODOTINTER or ODOTMETH, if appropriate. It also may add a StarExpr node to n.X as needed for access to non-pointer methods. If dostrcmp is 0, it matches the field/method with the exact symbol as n.Sel (appropriate for exported fields). If dostrcmp is 1, it matches by name exactly. If dostrcmp is 2, it matches names with case folding.
func Lookdot1(errnode ir.Node, s *types.Sym, t *types.Type, fs []*types.Field, dostrcmp int) *types.Field
Lookdot1 looks up the specified method s in the list fs of methods, returning the matching field or nil. If dostrcmp is 0, it matches the symbols. If dostrcmp is 1, it matches by name exactly. If dostrcmp is 2, it matches names with case folding.
func Lookup(name string) *types.Sym
func LookupCoverage(name string) *ir.Name
