Hi The sis variant of the sparc/erc32 BSP has existed a LONG time in RTEMS. It was needed to turn on about 50 lines of assembly that were needed to initialize the simulator but not the real erc32. This reflects the simulator existing before the hardware. The real erc32 configuration disables that code because it is not needed and thus undesirable for flight configurations.
Jiri Gaisler fixed the simulator well over a year ago so that the simulator is initialized in the same state as the real HW. This lets the erc32 BSP variant (without the special code) work on gdb/sis. Thus this variant isn't needed any longer. If this were ANY other BSP, this would barely rate a ticket. But this BSP variant was added in January 2006 and is featured in the Hello World task and various other instructions. There is no technical reason to keep this BSP but it is going to be a bit more difficult to completely clean up. Any objections to removing the unnecessary sparc/sis BSP variant before 4.12 branches? I plan to file a ticket and prepare a patch. It will take a village to make sure we catch all the places this is in instructions though. Thanks. --joel
