Priority: medium Bug ID: 80311 Assignee: dri-devel@lists.freedesktop.org Summary: 3D acceleration is broken with recent llvm and git Severity: major Classification: Unclassified OS: Linux (All) Reporter: half-shot@molrams.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/radeonsi Product: Mesa

Created attachment 101461 --> https://bugs.freedesktop.org/attachment.cgi?id=101461&action=edit glxinfo

On my RadeonHD 7950, some games will get as far as the menu but by using glxgears it segfaults on start with the message 'LLVM triggered Diagnostic Handler: unsupported call to function llvm.AMDGPU.rsq in main'. Some games will crash xorg, some will just segfault. SuperTuxKart has also been tested and the game does not crash until actual 3D elements are drawn, as with Team Fortress 2.

Distro is Arch Linux Environment is XFCE4 Kernel Version: 3.15.0-1-mainline glxinfo is dumped to file LLVM Version: 3.5.0svn (211341-1)

Thanks for checking.
