We are planning to have more changes coming up and thought it
would be good to have a few reviewers so they would
get reviewed in a timely manner.
I will dedicate more time to the power changes.
Ian and Austin should also be candidate reviewers, though they
might be busy working on other parts.
There will be at least one other person from IBM working with me on this
at least one reviewer who works on golang for IBM Z who has agreed to
changes too so I think I now have a good list in addition to you and the
others you mention.
What packages do you plan to work on? math and math/big next, perhaps?
We have a list of changes in mind, I'm trying to prioritize them now.
The hashing and crypto functions
are higher priority, but we do plan to fix the math and math/big packages.
We also need to work out runtime cpu feature detection story, so that we
could make use of latest Power 8 instructions for hash/crc and crypto/*
while preserving the ability to build and test on ppc970. (I'm fine if
use dedicated instructions for linux/ppc64le too.)
Do you have suggestions on doing this? On our compilers we have always
done this with a switch (e.g., -mcpu on gcc) but
according to previous responses switches are frowned upon in golang.
Doing power8 only with ppc64le is fine with me but
there were objections to that approach too.
In an earlier note exchange with Russ, he said it was OK to go ahead
with power8 only since the plan was
to start using a ppc64 BE power8 machine from OSU for building ppc64?
I had a question about the disassembler for ppc64/ppc64le that has
not been answered. Is there something I
can do there to help get that in place and working?
It's working, My repo for the disassemble package is athttps://github.com/minux/power64,
I have a few things to do before I can integrate it into cmd/objdump
I had seen this and tried to use it but hit some problems and gave up.
Can you provide directions on how
to build it? I'd like to be able to try it out even though it is not
I will definitely get it in in this cycle.
