- [dev.power64] runtime: replace getproccount with simpler code · ecbe6b9f
  Russ Cox authored Aug 14, 2014
```
This runs once. There is no need for inscrutable algorithms.
Also it doesn't compile correctly with 9c.

[dev.power64] cmd/9l, math/big, runtime, syscall: fixes for power64 · 6e73ae88

Russ Cox authored Aug 13, 2014

On the machine I'm using, the hardware page size seems to be 64 kB.
Make ELF rounding and mmap quantum 64 kB to match.

Error numbers returned from kernel are positive; do not negate.

Implement stubs for math/big.

[dev.power64] cmd/9g: do not ignore move instructions even if from and to are samaddr() · f285537b

Shenghou Ma authored Aug 13, 2014

Those moves might be significant (e.g. narrowing or widening): on Power64,
we don't distinguish between MOVWD and MOVW.

This fixes divmode.go and bug447.go.

[dev.power64] cmd/9a: use new flag parser · 53b78c84

Russ Cox authored Aug 12, 2014

Copy main from 6a. Fixes various things, but the
main thing is the use of the new flag parser.
The go command expects to be able to use -trimpath
and not have it be interpreted as -t rimpath.
