Hi, These patches reworks sightly glsl-to-tgsi ir_dereference* visitor. The first one is self explanatory. The second one factor ir_dereference* in a separate visitor ; by itself, this change does not bring anything to code generation, however it should make easier to handle case where variable location is not standard, for instance UBO. In addition glsl-to-tgsi should generate (U)MAD instead of (U)MUL and (U)ADD when there is 2 level indirect addressing (which is not very common at the moment). Third patch should help glsl-to-tgsi to avoid generating redondant (U)ARL opcode in indirect addressing. I tested it against piglit's tests/shaders/glsl-fs-vec4-indexing-temp-src-in-loop.shader_test and it removed a UARL instruction. As this patch changes the way relative addressing is treated, it might regress in some situation so it needs more testing that the previous ones.
