Well i put this as radeosi bug as i am not sure if happens elsewhere. It is LLVM bug actually which happens once subreg liveness is enabled, so svn 228228 is bisected as bad. I running current llvm with subreg liveness disabled, as this is major/grave one bug for me.
Same issue was present in Tom's perf branches last month once subreg liveness is enabled too.
Hardware is kabini (Athlon 5350), current Debian Sid 64bit, kernel 3.19.0, xserver git, mesa git, etc...
Attached is screenshot from Unigine Valley for example, there are major rendering issues in many other GL apps.
For Firefox crashing xserver not sure how to debug that (btw it crashed X immidiate at starting FF) , if i build llvm with debug and assertations screen/monitor somehow looks like it goes sleep mode (without any messages in logs) and only hard reset helps. If i build llvm without those it just crashing xserver, but there is not enough info in Xorg.0.log :(
