| // When clang suggests inserting [[clang::fallthrough]], it first checks if |
| // it knows of a macro expanding to it, and if so suggests inserting the |
| // macro. This means that this macro must be used only in code internal |
| // to v8, so that v8's user code doesn't end up getting suggestions |
| // for V8_FALLTHROUGH instead of the user-specific fallthrough macro. |
| // So do not include this header in any of v8's public headers -- only |
| // use it in src/, not in include/. |
