示例1: cnext
// Set a breakpoint at every reachable location, as well as the return address. Without
// the benefit of an AST we can't be sure we're not at a branching statement and thus
// cannot accurately predict where we may end up.
func (thread *Thread) cnext(curpc uint64, fde *frame.FrameDescriptionEntry) error {
pcs := thread.dbp.lineInfo.AllPCsBetween(fde.Begin(), fde.End())
ret, err := thread.ReturnAddress()
if err != nil {
return err
}
pcs = append(pcs, ret)
return thread.setNextTempBreakpoints(curpc, pcs)
}
示例2: next
// Set breakpoints at every line, and the return address. Also look for
// a deferred function and set a breakpoint there too.
func (thread *Thread) next(curpc uint64, fde *frame.FrameDescriptionEntry, file string, line int) error {
pcs := thread.dbp.lineInfo.AllPCsBetween(fde.Begin(), fde.End(), file)
g, err := thread.GetG()
if err != nil {
return err
}

f, lineno, _ := thread.dbp.goSymTable.PCToLine(g.DeferPC)
for {
lineno++
dpc, _, err := thread.dbp.goSymTable.LineToPC(f, lineno)
if err == nil {
// We want to avoid setting an actual breakpoint on the
// entry point of the deferred function so instead create
// a fake breakpoint which will be cleaned up later.
thread.dbp.Breakpoints[g.DeferPC] = new(Breakpoint)
defer func() { delete(thread.dbp.Breakpoints, g.DeferPC) }()
