load3232 and load6432 now limit their slice to its length. This improves safety, since encoders can no longer look at the part beyond the length. It also produces several dozen fewer instructions for bounds checks.

@greatroar Great. Could you double check that times are same or better? |
|
|
okie. I don't really see how it produces several dozen fewer instructions for bounds check: Seems like a SUBQ was replaced by a NEGQ - same latency and throughput. But as long as it isn't worse it's fine. Just want to know what to expect. |

Inlining is key. E.g. in Line 315 in 2f99358 the inlined load6432 previously had to fetch both len(src) and cap(src) from the stack to do the bounds check. It now only needs the length. |
