The function names are usually much longer than the small rectangles in the flame graph. The function names should not only be shown inside the rectangles when the space is big enough, but also unconditionally as tooltips.
Git commit f31b2605fbf863ab6bd4d1863125c8959807e1ef by Milian Wolff. Committed on 02/05/2017 at 20:57. Pushed by mwolff into branch 'master'. Also show tooltips with function identifiers Do not try to use fancy HTML formatting here though, as its making text elision harder than necessary. It would also break tooltips for very long function names which often happens in STL-using code.
