https://bugs.freedesktop.org/show_bug.cgi?id=37171 --- Comment #20 from Stefan Dösinger <stefandoesinger@xxxxxx> 2012-03-16 09:41:21 PDT --- Note that Shader Model 2 in d3d kinda supports loops and conditions on hardware that shouldn't be able to handle them. The caveat of this support is that they do not support dynamic branching. The loop counter is a uniform and cannot be changed at shader runtime, and there are no break statements or other ways to abort the loop before the iteration counter is reached. If statements only support uniforms as conditions as well. Wine translates those constructs into GLSL for loops and if statements that only read uniforms, the compiler should be able to unroll them. With ARB shaders we unroll them ourselves and generate one GL shader for each control uniform combination that is used by the application. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
