Memory Profiling Tool

Memory Profiling Tool

[mss59]

Is there any memory profiling and leak detection tool available which works
for both PPC and X86??

Thanks.

Here's what I know about.
1. There's a utility built into glibc which may be of some help:
http://www.gnu.org/manual/glibc-2.2.5/html_node/Allocation-Debugging.html#Allocation%20Debugging
but it's a bit minimal.

2. x86 only - valgrind, of course.  God's gift to x86 programmers.  Shame
it's not been ported to ppc.

3. libmudflap.  This is very promising; see
http://people.redhat.com/dnovillo/Papers/nordu2003-slides.pdf
http://www.linux.org.uk/~ajh/gcc/gccsummit-2003-proceedings.pdf
However, it's part of the SSA branch of gcc-3.4, so you'll need to use
something like http://kegel.com/crosstool to build it.
I am hoping to try this out on ppc sometime, but haven't yet.
FWIW, it's provided with Red Hat's taroon beta, so it must
be getting close to usable.

If you're debugging c++, you should also read
http://gcc.gnu.org/onlinedocs/libstdc++/debug.html

Parasoft Insure++ supports both x86 and PPC.

bgcc - bounds checking gcc - its a patch to gcc

the output will look something like this but can be tuned with compile time options:

Hey!  I didn't know that was still alive!  Thanks for the tip!
There's even a version for gcc-3.3.1 at
