◆ llvm_unreachable
| #define llvm_unreachable | ( | msg | ) | ::llvm::llvm_unreachable_internal(msg, __FILE__, __LINE__) |
Marks that the current location is not supposed to be reachable.
In !NDEBUG builds, prints the message and location info to stderr. In NDEBUG builds, becomes an optimizer hint that the current location is not supposed to be reachable. On compilers that don't support such hints, prints a reduced message instead and aborts the program.
Use this instead of assert(0). It conveys intent more clearly and allows compilers to omit some unnecessary code.
