The Linaro Toolchain Working Group is pleased to announce the availability of a "developer preview" of Valgrind which includes the support for ARM and Thumb which has recently been added by the Valgrind developers.

Our aim with this preview release is to advertise Valgrind's improved ARM support and encourage people to try it out and find bugs before the official 3.6.0 release. Please report bugs via upstream's BTS: http://valgrind.org/support/bug_reports.html or you can ask on linaro-toolchain@lists.linaro.org if you have any problems.

This release is a snapshot of upstream subversion; it should generally work but you may encounter bugs, especially if you run it on hand-optimised assembly that uses obscure instructions.

New (upstream) features in this snapshot include: * Greatly improved support for ARM * Support for the Thumb instruction set * Support for NEON and VFPv3 instructions

Known issues: * callgrind has difficulty identifying ARM function call and return so may not produce useful results

Downloads are available from the Linaro Overlay PPA: https://launchpad.net/~linaro-maintainers/+archive/overlay ...so if you're running Linaro on an ARM system you should be able to just install it with 'apt-get install valgrind'.
