mperf

Using the dynamic library piling method to perform library piling on the malloc calloc realloc free function can achieve memory analysis.

How to use？

Assume the file is located in /home/usr/mperf

COMPILE

Easily compile the code using compile.sh script

cd ./code
sh compile.sh

RUN

Add LD_PRELOAD = your_pth/mperf.so before run run.sh script

LD_PRELOAD=/home/usr/mperf/code/mperf.so ./run.sh

ANALYSE

Visual processing can be done using the provided python script

LD_PRELOAD=/home/usr/mperf/code/mperf.so ./run.sh | python /home/usr/mperf/draw/dispatch.py

python /home/usr/mperf/draw/draw.py

After that can get an output like this:

ps. If do not output the function call stack information, please use ./code/mperf_less.cc instead, it will greatly reduce the running time and the size of the generated analysis file.
