There's really not many. The main use of NOP is when we change the opcode of an instruction we want to remove to NOP, and then make a separate pass after the optimization to remove NOP instructions (to avoid removing things and changing instruction IPs which are used for liveness checks). Other than that, there's not really anything else. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
