◆ PRISM_ASSUME
| #define PRISM_ASSUME | ( | expr_ | ) | __builtin_assume(expr_) |
Tell the compiler that the given expression can be assumed to be true.
Unlike assert, this emits no runtime check — it only feeds the optimizer's value range analysis so it can prune impossible paths. Use it to communicate an invariant the caller guarantees but that the compiler cannot otherwise prove.
