Subject: Daniel's weekly report #6

Hello!

This was a really bad week for me, I just couldn't get the LDS/GDS
instructions to work. I asked on the AMD forums about it, here is the
thread: http://devgurus.amd.com/message/1298811. (My last reply is
currently being moderated)

At least I know now what the issue is (not defining LDS size), but I still
need to find out where the LDS size is stored. As I mentioned in the
thread, there seems to be no documentation about this. Please correct me if
I'm wrong, I would be really glad to find such docs.

The other approach to optimization would be using SGPRs for computation,
which would only be useful if all the threads need the same values computed.

Next week I won't be able to work, due to my family going on vacation. This
is terrible timing, since the midterm evaluations are coming just next
monday.

I'm really sorry about all of these issues. I'll try to make up for all the
lost time/progress in the future.

Accomplishments:
1. Added support for user-defined formats
2. Tried and failed to use DS instructions

Priorities:
(The priorities from last week aren't changed much)
1 - Try to optimize formats
2 - Get DS instructions to work and find out how they could improve
performance
3 - Explore the possibility of computing using SGPRs further

Regards,
Daniel
