[Valgrind-developers] Data tracking tool

[divya a. <div...@ya...>]

Hi,
I am a Ph. D. student and as part of my research, I
augmented callgrind to do data structure level
profiling i.e. the tool outputs the data structures
 accesses by each user function in the running
program.  It outputs the
 following information about these accesses 
- whether the data structure is global/stack
variable/heap variable 
- size
- for stack variable: function in whose stack the
variable is located +
 offset from stack start 
- for heap variable: address + function that performed
the allocation
 I used this tool to evaluate the amount of data
transfer between different functions if they were
executed on , say, different processors.  I was
wondering if there has been a talk about such a tool
and if  it would be useful to other people. Of course,
the code is not release quality yet but I can work on
it. 
Thanx,
Divya
