示例1: callSSA
// callSSA interprets a call to function fn with arguments args,
// and lexical environment env, returning its result.
// callpos is the position of the callsite.
//
func callSSA(i *interpreter, caller *frame, callpos token.Pos, fn *ssa.Function, args []value, env []value) value {
if i.mode&EnableTracing != 0 {
fset := fn.Prog.Fset
// TODO(adonovan): fix: loc() lies for external functions.
fmt.Fprintf(os.Stderr, "Entering %s%s.\n", fn, loc(fset, fn.Pos()))
suffix := ""
if caller != nil {
suffix = ", resuming " + caller.fn.String() + loc(fset, callpos)
}
defer fmt.Fprintf(os.Stderr, "Leaving %s%s.\n", fn, suffix)
}
fr := &frame{
i: i,
caller: caller, // for panic/recover
fn: fn,
}
if fn.Parent() == nil {
name := fn.String()
if ext := externals[name]; ext != nil {
if i.mode&EnableTracing != 0 {
fmt.Fprintln(os.Stderr, "\t(external)")
}
return ext(fr, args)
}
if fn.Blocks == nil {
panic("no code for function: " + name)
}
}
fr.env = make(map[ssa.Value]value)
fr.block = fn.Blocks[0]
fr.locals = make([]value, len(fn.Locals))
for i, l := range fn.Locals {
fr.locals[i] = zero(deref(l.Type()))
fr.env[l] = &fr.locals[i]
}
for i, p := range fn.Params {
fr.env[p] = args[i]
}
for i, fv := range fn.FreeVars {
fr.env[fv] = env[i]
}
for fr.block != nil {
runFrame(fr)
}
// Destroy the locals to avoid accidental use after return.
for i := range fn.Locals {
fr.locals[i] = bad{}
}
return fr.result
}示例2: prettyFunc
// prettyFunc pretty-prints fn for the user interface.
// TODO(adonovan): return HTML so we have more markup freedom.
func prettyFunc(this *types.Package, fn *ssa.Function) string {
if fn.Parent() != nil {
return fmt.Sprintf("%s in %s",
types.TypeString(this, fn.Signature),
prettyFunc(this, fn.Parent()))
}
if fn.Synthetic != "" && fn.Name() == "init" {
// (This is the actual initializer, not a declared 'func init').
if fn.Pkg.Object == this {
return "package initializer"
}
return fmt.Sprintf("%q package initializer", fn.Pkg.Object.Path())
}
return fn.RelString(this)
}
