Priority: medium Bug ID: 66331 Assignee: dri-devel@lists.freedesktop.org Summary: WebGL water demo crashes LLVM Severity: normal Classification: Unclassified OS: Linux (All) Reporter: greg@chown.ath.cx Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/DRI/R600 Product: Mesa
Created attachment 81647 --> https://bugs.freedesktop.org/attachment.cgi?id=81647&action=edit 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.
