# Unfortunately FreeRTOS entirely hides the contents of the TCB inside of
# tasks.c but it's necessary for snapshot processing in order to access the
# stack limits. Set this to a pw_source_set which provides the tskTCB struct
# definition for snapshot to work with FreeRTOS. By default, this is
# auto-generated from FreeRTOS sources and shouldn't need to be manually
# modified.
