The compiler in theory should optimize register allocation, but the problem is that r600g still lacks real register allocator. And probably some changes since 7.11 increased register usage in the TGSI IR. I'll see if I can help with that shader somehow, but generally r600g needs a better shader compiler. There is some work in progress on that, but I don't know when it will be completed. Also there is some experimental code that probably could help with that, but currently it works only with evergreen GPUs. If you could use a gpu of the evergreen class (IIRC it's all of 5xxx, some of 6xxx cards), then you might want to try r600_shader_opt and r600_shader_opt_2 branches from the following repo: https://github.com/VadimGirlin/mesa -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
