I would like to be able to run a simple C program and have some tracer
or profiler log each time the C program line changes (timestamp the
event, etc).  then I'd like to have that log be shown in a text edit
window (something graphical) that would highlight the lines that were
'hit' during the run.  it would be nice to number the lines by the
order they were run in (that's 2 columns: the physical line # and the
order of execution number).

seems simple - seems like there should be some already-made solutions
for this (assuming unix, gcc, etc) - but I haven't found anything yet.
anyone have any ideas?

my dream solution would be to run a program that has been somehow
instrumented, have this logfile be simple enough so that I could load
it in emacs along with the source file and it could highlight the lines
that were run, based on that logfile.  just a quick way to sort out
which are the 'cold' sections of code during a particular run.

TIA,

/bryan

NEW GRAND UNIFIED THEORY DISCLAIMER: The manufacturer may
technically be entitled to claim that this product is
ten-dimensional. However, the consumer is reminded that this
confers no legal rights above and beyond those applicable to
three-dimensional objects, since the seven new dimensions are
"rolled up" into such a small "area" that they cannot be
detected.
