That point seems a bit moot to me, we already need to make some parts of
i-g-t optional and the assembler would be one instance of that. I'm also
willing to do the work to ensure that's done.

Yes, I agree, and I think having that effort done in i-g-t makes sense
as I'd like to chip away at things like a tool to analyse the last batch
buffer after a hang for instance. Sharing that code better is definitely
what is motivating to look at that.

I've started a series to synchronize the brw_*[ch] files with Mesa's but
I have to admit I did not look at Chris' libbrw. The changes I have so
far are definitely a step towards the right direction though as Chris
seems to have started with more recent versions of Mesa's files than the
ones we have in the assembler.

Hopefully I'll have a first pass done this week. I also had a looks at
Chris' libbrw. It does look good but diverges a bit from Mesa now, what
I'd love to have is the same thing everywhere, but I guess that's a long
shot.
