And a good thing this is. If this had not happened, we'd have 3 different R600 LLVM back-ends to choose from when writing code. Mesa's R600 back-end, Tom's LLVM tree, or the upstream LLVM repository. Any fixes/improvements would have to be synchronized between all 3 repositories.
Now we're down to 2 repositories, and I believe that Tom has committed to handling the upstreaming of fixes based on his tree to the upstream LLVM project.

well, it's great that we have llvm for radeon
but there's 2 (or some more - haven't tested more than that) main issues I'm facing with it when for my daily work:
I'm running compiz 0.8* (0.9* is unstable for me and it's also not as fast & stable as 0.8* - at least for me)
- the expos?-like feature leads to a black screen
- likewise with the zoom feature
if anyone of the devs is reading here along - could you try to reproduce and see if there's a fix for that ?
(I'm using llvm from Tom's repo via FireBurn overlay with Gentoo)
afaik at the beginning when I started testing it some videoplayback (via smplayer) or even flash (in chromium) also didn't work -> black content
Typical case of mild form of idocracy ;-) At least MESA should have left the code within their codebase as long as LLVM hasn't the backend officially ...
when triggering the expos?-like feature (vortex animation is selected) for a short second I can see the background - then the screen turns black
also switching desktops via ctrl + alt + arrow (left, right, up, down) also leads to a black screen - when the animation has ended the desktop is viewable again
when zooming in (using the "zoom" feature) the mouse-cursor is still viewable - not sure if it was there before
definitely things seem to be improving
thanks devs !
in the past when I first wanted to try out llvm upon launch of X (lightdm) the screen was totally black - so there's been lots of progress

Which card do you have ? Maybe compiz is triggering a bug not covered by piglit.
