Daniel Covington 6e6c16aa23 vim: paint and edit in machine code, redraw only changed rows The single-row painter became vml.s at $C000: one sys() paints all 24 rows, memmove and line-index fix-ups run in ML, and the keyboard buffer is popped with IRQs masked. dall() repaints only the cursor row or the whole screen, so j went from 17 to 0-3 jiffies.

Daniel Covington 6e6c16aa23 vim: paint and edit in machine code, redraw only changed rows

The single-row painter became vml.s at $C000: one sys() paints all 24
rows, memmove and line-index fix-ups run in ML, and the keyboard buffer
is popped with IRQs masked. dall() repaints only the cursor row or the
whole screen, so j went from 17 to 0-3 jiffies. Loading now checks the
drive error channel and splits lines over 80 columns. The temporary
jiffy counters used to measure the speedup are removed; the numbers are
in NOTES.md.
