Hi guys,
I get a hang with commit "gallium/radeon: re-enable unsafe math for graphics shaders."
I've attached R600_DEBUG=ps,vs with and without this commit.
I'm using llvm git and kernel 4.1.3
Thanks for your help, sarnex

--- Comment #4 from sarnex commendsarnex@gmail.com --- I cannot reproduce this on llvm git, older llvm, or older mesa. Maybe the game changed.

--- Comment #5 from Marek Olšák maraeo@gmail.com --- Hi sarnex,
Could you please re-enable unsafe math and test if it works with Dota 2 Reborn now? Mesa master has some fixes which might fix the hang. We need to enable unsafe math for better performance.
Thanks.

Hi Marek,
I cannot reproduce the hang or any issues with the game with your patch for unsafe math on the ML.
Thanks, sarnex
