[GitHub] [incubator-nuttx] Ouss4 opened a new pull request #5790: xtensa_coporc: Adjust stack frame for C callable coprocessor functions

Ouss4 opened a new pull request #5790:
URL: https://github.com/apache/incubator-nuttx/pull/5790


   ## Summary
   These function don't use call8 or call12 and thus need to create just 16
   bytes for the base save area, however they do use one variable so we
   need a space for that.  The `entry` instruction works in multiples of 8 bytes
   so we add whole 8 bytes for one variable.
   ## Impact
   Xtensa chips
   ## Testing
   ESP32, ESP32-S2 and ESP32-S3.
