| Summary : memory allocation profiler for C/C++ programs
|
Description :
mpr is a memory allocation profiler for C/C++ programs.
mpr finds malloc/realloc memory leaks and memory allocation statistics by
using a simple, brute force strategy: log all malloc/free calls to a file and
post-process this log file when the program terminates.
mpr keeps track of the entire call chain leading up to a malloc/free call. This
is superior to conventional methods that keep track of only the immediate
caller using __FILE__ and __LINE__ pre-processor tricks.
As of version 2.0, you no longer need to re-link your application in order to
use mpr. If your program is dynamically linked, using mpr can be as simple as
typing \'mpr program ...\' (see mpr.html for details).

To give you an idea of what mpr can do, here are some sample outputs:
(1) memory allocations grouped by call chains:
(col2=number of allocs, col3=amount allocated, col4=percent)
main(tst.c,52) 55 1760 2.35%
foo(bar.c,14):bar(bar.c,28):main(tst.c,59) 200 2000 2.67%
main(tst.c,47) 200 3200 4.27%
foo(bar.c,19):bar(bar.c,28):main(tst.c,59) 200 4000 5.34%
foo(tst.c,34):main(tst.c,58) 200 12800 17.08%
foo(baz.c,21):baz(baz.c,29):main(tst.c,60) 200 51200 68.30%
(2) memory leaks grouped by call chains:
(col2=number of allocs leaked, col3=amount leaked, col4=percent)
main(tst.c,47) 52 832 2.36%
foo(bar.c,14):bar(bar.c,28):main(tst.c,59) 88 880 2.50%
main(tst.c,52) 31 992 2.82%
foo(bar.c,19):bar(bar.c,28):main(tst.c,59) 103 2060 5.85%
foo(tst.c,34):main(tst.c,58) 108 6912 19.62%
foo(baz.c,21):baz(baz.c,29):main(tst.c,60) 92 23552 66.86%
(3) memory allocations grouped by size:
(col1=size, col2=number of allocs, col3=amount allocated col4=percent)
32 55 1760 2.35%
10 200 2000 2.67%
16 200 3200 4.27%
20 200 4000 5.34%
64 200 12800 17.08%
256 200 51200 68.30%
(4) memory leaks grouped by size:
(col1=size, col2=number of allocs leaked, col3=amount leaked, col4=percent)
16 52 832 2.36%
