[Valgrind-users] Regarding use of Lackey to trace midway execution of a program

[SAI G. M C P. E. S. <sai...@pe...>]

Hi,

We are students working on memory access analysis, using the Lackey tool in
Valgrind.
Our memory trace results in a large log file, and we need the trace from
discrete points of execution (between 40-60%).
Instead of logging completely, and splitting manually, is there a way we
can modify the Lackey command to pick from a desired point in the execution?

For reference, the command we use is
$ valgrind --tool=lackey --trace-mem=yes --log-file=/path_to_log ./program

We need to modify this to command to trace from 40-60% of the program

Regards
