  • score/include/rtems/score/heap.h: Declare _Heap_Get_first_and_last_block(). Removed Heap_Extend_status. Changed return type of _Heap_Extend() to bool.
  • score/inline/rtems/score/heap.inl: Define _Heap_Set_last_block_size().
  • score/src/heap.c: Define and use _Heap_Get_first_and_last_block().
  • score/src/heapgetinfo.c: Removed assert statements. Do not count the last block. This ensures that all size values are an integral multiple of the page size which is consistent with the other statistics.
  • score/src/heapextend.c: Implemented support for scattered heap areas.
  • score/src/heapwalk.c: Dump also last block. Changes for new first and last block values.
  • ./score/src/pheapextend.c, rtems/src/regionextend.c: Update for _Heap_Extend() changes.
  • Property mode set to 100644
