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

display top CPU processes top tool

[John Zhou]

Hi, all

I'm using "top" tool to display top CPU processes and system running information in my Embedded Linux based on PowerPC. But, when I run "top" command in prompt #, it's coming on:

# set
PS2=>
PS1=#
IFS=
USER=root
SHELL=/bin/sh
PATH=/usr/bin:/bin:/usr/sbin:/sbin
HOME=/
TERM=ansi
#
# top
top: Unknown terminal "ansi" in $TERM
#

I changed to :

# export TERM=VT100
# set
PS2=>
PS1=#
IFS=
USER=root
SHELL=/bin/sh
PATH=/usr/bin:/bin:/usr/sbin:/sbin
HOME=/
TERM=VT100
# top
top: Unknown terminal "VT100" in $TERM
#

Another question:

How to use "top" with option to save cpu information to a log file?

Thanks for any help.

Do you have a /etc/TERMCAP ?

Use strace to see what it's looking for.

Re: display top CPU processes top tool

[Mark Hatle]

I bet that top is linked with ncurses instead of termcap.  As such look
at /usr/share/terminfo on the target and make sure the appropriate
directories and terminal emulations are there.
