Default Valgrind 3.6.0 supports ARMv7
Nearly 3-week old news, but i just noticed it:

Quote:
* ================== PLATFORM CHANGES =================

* Support for ARM/Linux. Valgrind now runs on ARMv7 capable CPUs
running Linux. It is known to work on Ubuntu 10.04, Ubuntu 10.10,
and Maemo 5, so you can run Valgrind on your Nokia N900 if you want.

This requires a CPU capable of running the ARMv7-A instruction set
(Cortex A5, A8 and A9). Valgrind provides fairly complete coverage
of the user space instruction set, including ARM and Thumb integer
code, VFPv3, NEON and V6 media instructions. The Memcheck,
Cachegrind and Massif tools work properly; other tools work to
varying degrees.
Anyone tried it yet?

Default Re: Valgrind 3.6.0 supports ARMv7
Thanks for the news. Is it running only on N900, or can we use it to analyze ARM binaries on x86 too? I mean, will it be able to run on Scratchbox or MADDE?

I'm not sure what you mean and I haven't looked at the insides of the file but it should be something like extracting it and running

./configure
make
make install

as root in a terminal.

No idea, what's XT? I didn't package it, just built it and selectively copied bits across (the entire thing is around 55MiB).

Probably on-device only. On (Diablo) scratchbox the same binary bails out with:

Code:

valgrind:  Fatal error at startup: a function redirection
valgrind:  which is mandatory for this platform-tool combination
valgrind:  cannot be set up.  Details of the redirection are:
valgrind:  
valgrind:  A must-be-redirected function

valgrind:  package on this machine.  (2, longer term): ask the packagers
valgrind:  for your Linux distribution to please in future ship a non-

valgrind:  that exports the above-named function using the standard
valgrind:  calling conventions for this platform.
valgrind:  
valgrind:  Cannot continue -- exiting now.  Sorry.
I'm not sure if/how this can be worked around. FWIW libc6-dbg is already installed.

Now go forth and package; package like you've never packaged before.

Oh, ok. Just uploaded valgrind_3.6.0-1 to Diablo extras-devel. Note that I haven't tested it because I don't have enough free rootfs space to install it at the moment :-(

I Compiled valgrind-3.6.0-SVN-r11479 for fremantle (inside scratchbox2). I didn't make any code changing, I only tuned configure script (cite: http://permalink.gmane.org/gmane.com...valgrind/10563)

Code:
Index: configure.in
===================================================================
--- configure.in	(revision 11479)
+++ configure.in	(working copy)
@@ -158,7 +158,7 @@
         esac
         ;;
 
-     armv7*)
+     arm*)
 	AC_MSG_RESULT([ok (${host_cpu})])
 	ARCH_MAX="arm"
 	;;
It compiles without warnings. I installed it to /opt/valgrind and dropped to N900-device.

Running on the device gives same error:

I think solution is installing package: libc6-dbg
At this moment I can't install that.
