Created attachment 37984 [details] Screenshot The game Serious Sam 2 have regressed lately, enemies are no longer visible. Bisecting leads to this: 96b11f1e3ee12f06be1d33bf085bf1353f23e667 is the first bad commit commit 96b11f1e3ee12f06be1d33bf085bf1353f23e667 Author: Eric Anholt <eric@anholt.net> Date: Wed Jul 21 18:29:06 2010 -0700 i965: Support relative addressed VS constant reads using the appropriate msg. The previous support was overly complicated by trying to use the same 1-OWORD message for both offsets. :040000 040000 11fced2877ca7e063dbef733d62aba43d198fc28 90ac0a3017df7c2f1ea4f5d699062f7877460ddb M src Automagic revert didn't work, so it's not confirmed.
Another instance of this bug is missing models in 3DMark 2001 (running in Wine), benchmark three "Lobby". http://www.futuremark.com/download/3dmark2001/
This is also what's causing the models in the menu in Heroes of Newerth to go missing: http://www.heroesofnewerth.com/download.php (Not confirmed by reverting, just by trying the commit prior to 96b11f1)
Could you try: commit 5360c48317f5806c7ea8814002e9aac2041960a7 Author: Eric Anholt <eric@anholt.net> Date: Mon Aug 30 11:19:30 2010 -0700 i965: Clear the cached constant buffer entry in the VS at control flow. Fixes the 7 regressions with constant buffers forced on with piglit -t glsl (glsl-vs-if-*). Before that, VS constant buffers could be full of all sorts of insanity.
No change in any of the games.
Several of the other "invisible characters" games were fixed when loop unrolling was merged. Could you retest?
No change here, I don't think Serious Sam 2 uses GLSL.
These regressions should be fixed by: commit 5dc53444c8323c1787dddbe6b67048828df9c684 Author: Eric Anholt <eric@anholt.net> Date: Wed Dec 22 22:46:12 2010 -0800 i965: Correct the dp_read message descriptor setup on g4x. It's mostly like gen4 message descriptor setup, except that the sizes of type/control changed to be like gen5. Fixes 21 piglit cases on gm45, including the regressions in bug #32311 from increased VS constant buffer usage. (the pre-96b11f1e3ee12f06be1d33bf085bf1353f23e667 read message type had a value of 0, so the bitfield being misplaced didn't matter). Please reopen if the regressions persist.
