Also fix inconsistent SWPRI define in interrupt handler
- Disable interrupts prior to allocating a large exception frame; only reenable them after deallocating the extra memory. - Any user tasks with stacks based on TX_MINIMUM_STACK do not have sufficient space for both a context switch frame and an ISR frame; ill-timed interrupts were causing stack overruns.
- Must reload register trashed by notify hook function call - Must ensure PS.WOE is set before using call8 - Remove unused XT_USE_INT_WRAPPER define and associated changes, which had a bug in XEA2 usage - Fix another case where enabling the thread notify hooks for call0 ABI corrupted a register
- ThreadX change to handle dynamic reent for both newlib and xclib - Adapt ThreadX xclib interface code to handle dynamic reent pointers
- Update upstream execution profiling for Xtensa port
- tx_execution_profile.h now defines an Xtensa example in addition to the existing Cortex example

@fdesbiens thank you for taking a look. I have not submitted PRs to eclipse projects before, so please LMK if there is any part of the process I may have missed or additional steps required. Thanks in advance. |
