Has unrolled loop for aligned-to-aligned copy. Notes: 1. this code tuned for DEC 5000/200. ioasic decstations do more unaligned copies. Better than old non-unrolled loop, but could be improved. 2. Undoes changes made for MIPS3 with comment implying an r4000 TLB bug. We can't reproduce this on 5000/150 (jonathan) or 5000/50 (mhitch). Calls to previous bcopy with a bad address show similar symptoms, reporting a trap in bcopy() after bcopy() has returned. Same thing?? Needs re-checking on an r4000 with no L2 cache. |
