Message: [QUOTE="Keith Thompson, post: 4214988"] Not everyone is; most of us are specifically allowing for the possibility of values other than 0 and 1. I think the OP is trying to minimize branching, not eliminate it altogether. An ideal solution to his problem would be an operator that acts like && except that it doesn't short-circuit (if C had such an operator). The branching implied by the "if" is unavoidable. Hmm. static inline int and(x, y) { return !!x & !!y; } if (and(and(a, b), c)) { /* Do stuff */ } (untested) On the other hand, the OP had said this code is running on a GPU, and he's using a specialized compiler for a language very similar to C, but not quite C. It could be that others have run into similar issue, and that the tools he's already using provide better solutions than anything we C folks can come up with. [/QUOTE]
