Use CI-CD-Github-Actions for spelling and formatting, add in the bot formatting action, update the CI-CD workflow files. Fix incorrect spelling and formatting on files. (#1083) 
* Use new version of CI-CD Actions,  checkout@v3 instead of checkout@v2 on all jobs
* Use cSpell spell check, and use ubuntu-20.04 for formatting check
* Add in bot formatting action
* Update freertos_demo.yml and freertos_plus_demo.yml files to increase github log readability
* Add in a Qemu demo onto the workflows.

README.md

This proof demonstrates the memory safety of the TaskDelay function. We assume that pxCurrentTCB is initialized and inserted in one of the ready tasks lists (with and without another task in the same list). We abstract function xTaskResumeAll by assuming that xPendingReadyList is empty and xPendedTicks is 0. Finally, we assume nondeterministic values for global variables xTickCount and xNextTaskUnblockTime, and pdFALSE for uxSchedulerSuspended (to avoid assertion failure).

Configurations available:

  • default: The default configuration.
  • useTickHook1: The default configuration with INCLUDE_vTaskSuspend=0

This proof is a work-in-progress. Proof assumptions are described in the harness. The proof also assumes the following functions are memory safe and have no side effects relevant to the memory safety of this function:

  • vPortEnterCritical
  • vPortExitCritical
  • vPortGenerateSimulatedInterrupt
