I think we're using the wrong terminology here. Instructions don't have widths; registers do. Instructions have execution sizes (and so you should use the BRW_EXECUTE_* macros). I guess I'm having a hard time seeing the whole picture, i.e., what explicit instruction execsizes buys us. Is there a branch with work that builds on this that I should look at? _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
