I agree with Dan. It doesn't save any real memory either as the compiler/linker reuses the repeated string. It might, depending on the compiler, save a few bytes of object code as the compiler may not optimize the repeated call away though. But a good compiler could do that too. _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
