Created attachment 81647 [details] Dump with R600_DEBUG=ps,vs,fs The WebGL demo http://madebyevan.com/webgl-water/ crashes r600g with LLVM enabled: firefox: /home/greg/build/llvm-3.3.src/include/llvm/CodeGen/MachineInstr.h:272: llvm::MachineOperand& llvm::MachineInstr::getOperand(unsigned int): Assertion `i < getNumOperands() && "getOperand() out of range!"' failed. Stack dump: 0. Running pass 'Function Pass Manager' on module 'tgsi'. 1. Running pass 'R600 Emit Clause Markers Pass' on function '@main' Aborted (core dumped) This happens both with LLVM 3.3 and latest code from SVN. I tried to dump a detailed log, but it actually crashes in a different place when dumping the shaders - might be related though. Log is attached.

With current Mesa CVS (10.0.0! ;-) on RV730 AGP I get this,too. Pure LLVM (3.3 stable) bug, NOT sb. setenv R600_DEBUG nollvm Works OK. Nice link, Grigori!

Dump with R600_DEBUG=3Dps,vs,fs
Does it work with llvm 3.4svn ? Here it seems llvm can compile the shader without crashing.
Sorry, I haven't have LLVM SVN on this system. -Dieter
Is a backport possible for stable (3.3)? Couldn't switch all to devel...;-)
OK, now I'm on openSUSE 13.1 kernel 3.13.1 LLVM 3.4 ;-) Mesa git-c849ecc r600g (RV730 AGP) Works so far, but... ...reflection corruption, see attachment. With R600_DEBUG=3Dnollvm it is fine.

I have llvm from git compiled a week or so and the rest of the stack yesterday and use a 8570D IGP and the demo works fine on Seamonkey 2.23 with or without llvm (Seamonkey uses the Firefox engine). I have layers.acceleration.force-enabled set to true. Older versions of llvm had some issues with this demo, crashed the browser or specular lighting was missing.

I said that I have 3.4 final (current stable)... Anyway, it is FIXED, now! - GREAT job! openSUSE 13.1 kernel 3.13.1 LLVM 3.4 ;-) Mesa 10.1.0-devel (git-16215a9) --- The first r600g geom shader (OpenGL 3.3) tree. --- But I have to patch = my kernel...;-) r600g (RV730 AGP) Konqueror 4.12.2 (KDE 4.12.2) Could be CLOSED, now.
