Deleted thumb check #1315

commented May 14, 2019

Pull Request Overview

This pull request deletes the thumb check in the kernel to keep it platform agnostic. I'm working on getting Tock running on risc-v and this check caused a problem when trying to run an application.

Testing Strategy

I ran it on the Hail board using the blink app and everything seems to be in working order. Also allows load processes to complete on the Arty-e21 (risc-v board).

TODO or Help Wanted

Not sure if this check needs to be put somewhere else in the platform specific code.

Documentation Updated

  • Updated the relevant files in /docs, or no updates are required.


  • Ran make formatall.

This was only really ever there as a sanity check. The compile process in libtock-c for ARM Cortex-Ms already ensures that code is compiled into thumb mode. I'd say we're probably good just removing this altogether rather than trying to add chip-specific process checks.
