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
