1090414 - Add "Collapse Recursion" option

Status: RESOLVED DUPLICATE of bug 1127455

(DevTools :: Performance Tools (Profiler/Timeline), defect)

Description

[Nick Fitzgerald [:fitzgen] [⏰PST; UTC-8]]

We should have a "Collapse Recursion" checkbox next to the "invert call tree" checkbox.

If you had a call tree like this:

  A
  |- B
  |  `- B
  |     `- B
  |        `- C
  `- D

Checking "collapse recursion" box would result in a call tree like this:


  A
  |- B
  |  `- C
  `- D

And all the weights/durations/samples/etc for the B calls would get combined as well.
