[GitHub] [incubator-nuttx] Ouss4 opened a new pull request, #6231: xtensa_sigtramp.S: Remove unnecessary entry instruction

Ouss4 opened a new pull request, #6231:
URL: https://github.com/apache/incubator-nuttx/pull/6231

   ## Summary
   `_xtensa_sig_trampoline` is not called the usual way with window calls (call4, call8 and call12), we get there from a context switch after modifying the task's PC.  The `entry` instruction here is not required, besides it creates a frame that confuses the backtrace at that point.
   ## Impact
   Xtensas chips.
   ## Testing
   ESP32, ESP32-S2 and ESP32-S3.
