[dev.power64] cmd/9c: fix switch bug · 95e8a3a1

Shenghou Ma authored Aug 07, 2014

The cmd/cc bundled with 9c has additional code compared to our cmd/cc, and
without those code, 9c couldn't handle switch statement where the expression
is not just a simple int32 or int64 variable (e.g. g->status or int8 variable).

All credit goes to rsc.

cmd/gc: make liveness ~10x faster · 7aa3031e

Russ Cox authored Aug 06, 2014

1) The arrayindexof lookup function is O(n). Replace with O(1) lookups.

2) The checkptxt function is O(n²) and is purely for debugging.
Only run when the debugging flags are turned on.

3) Iterating over sparse bitmaps can be done faster word by word.
Introduce and use bvnext for that.

Run times before and after, on my 2.5 GHz Core i5 MacBook Pro.
