More exactly, the GCC backend source code for Power still lives in config/rs6000/. Since we usually say Power these days (not PowerPC), and the bareword "power" would be confusing, there isn't very much benefit to renaming it (just cost). It also is nice that when people say "rs6000" you know they are talking about the GCC port, not something else PowerPC :-) > There are lots of > references to rs/6000 in the GCC manual, do you think they should all be > deleted? (The answer is no, they shouldn't). Since I removed the RIOS (the processor in RS/6000 machines) support quite some time ago now, yes, updating the manuals with more up-to-date examples would be useful. But only if this is *correct*. Simply deleting everything RS/6000 is just loss. Segher
