Hi All,
I'm badly in need of a histogram-based profiler for the VM I'm working on. This is something that produces a histogram of time taken against PC, insead of time taken against function. The interpreter is a very large function and so function-centric tools aren't (IME) that useful. I've written ones for BrouHaHa and VisualWorks and will write one again if pushed. But I wonder whether anyone knows of anything off-the-shelf or close enough to be wroth using as a starting point. For example, has anyone written a graphing tool in Squeak using Morphic that I could steal for the UI? Yes I could start with gprof and/or gcov but I find graphical histograms much more immediate and helpful.
TIA
Eliot
