I made a patch for ltrace that adds support for Thumb-2. There's not much to it, but it allows me to trace applications built for Cortex-A8. Without it, users will experience this bug:
https://bugs.launchpad.net/ubuntu/+source/ltrace/+bug/639796
Unfortunately, it appears that the upstream tree is not well-maintained. I posted it to the mailing list for the project, but others' patches have been ignored for many months. However, my post precipitated another contributor to offer to maintain the package.
I also posted this patch as the proposed solution for the above LP bug, which should allow Linaro to benefit from the work without worrying about upstream. In fact, a new version of the package appears to have been released that includes my patch (0.5.3-2ubuntu6). Please give this updated package a whirl and let me know if there is more work to be done.
Thoughts? Unless I hear feedback from others, I will assume that this tool now works for Cortex-A[89] and move on to other tasks.
