[Mono-dev] PPC64 - is it any closer

[Andreas Färber]

Hi Paul et al.,

I have been offline for some weeks. Some smaller patches were posted  
before that time, but there has still been no review yet to my  
knowledge. This includes my long-standing enhancements to ppc(64) code  
generation [2], some signedness changes for OSX, some guint32 ->  
gulong changes (e.g., [1]), and Olaf posted a ppc64-related patch to  
use GCC 4.1's new built-in atomic ops when available [3].

There is a ticket tracking ppc64 progress:
https://bugzilla.novell.com/show_bug.cgi?id=324134

I have multiple Git branches on repo.or.cz:
http://repo.or.cz/w/mono/afaerber.git
- ppc64-cleanup includes cosmetic changes that help with our changes  
and their review
- ppc64-functional includes functional ppc changes in addition to the  
cosmetic ones
- ppc64 tracks the "final" work-in-progress (Two patches from Olaf's  
branch I still need to apply there.)
- ppc64-todo sometimes has changes on top of ppc64, to keep TODOs out  
of the patches
Getting rebased all the time, I admit they are not comfortable to read  
log-wise but the patches posted in Bugzilla can be extracted by `git  
diff master2..ppc64-cleanup`, `git diff ppc64-cleanup..ppc64- 
functional` etc.

Regarding the time frame, I've worked on the port since Q2 2007 as  
time permits, and the big obvious hurdles have been taken; now it's  
mostly rebasing against breaking changes in trunk and about debugging.  
Any help and ideas where the crashes/hangs/whatever-it's-currently may  
stem from are highly appreciated.

If we could get an okay to apply some of our smaller non-intrusive  
changes (below) to trunk, it would greatly help our porting effort and  
Geoff, Paolo or whomever with the review of the "real" JIT changes.

Regards,

Andreas
