Description

I ran rustc --target $TARGET for

  • xtensa-esp32-espidf
  • xtensa-esp32-none-elf
  • xtensa-esp32s2-espidf
  • xtensa-esp32s2-none-elf
  • xtensa-esp32s3-espidf
  • xtensa-esp32s3-none-elf

And for all of them, I got a warning that 'esp32' is not a recognized processor for this target (ignoring processor) (or esp32-s2 or esp32-s3 respectively).

Additionally for xtensa-esp32s2-none-elf, I also got '+forced-atomics' is not a recognized feature for this target (ignoring feature)
