Intrinsics
Intrinsics is any special case which compiler may override or re-write its implementation based on what is known at that build process. The porpuse is make possible some sort of flexibility when doing compilation through source code
Name
Description
sizeof(T)Size (in bytes) of type T at compile time.alignof(size)Specifies or queries alignment requirement in bytes (power-of-two multiple).bitcast()Reinterprets the underlying bits of a value as another type of the same size without changing the data.trap()Emits an unrecoverable runtime trap instruction that immediately aborts execution.debugtrap()Emits a breakpoint trap intended for debuggers; stops execution only under debugging.unreachable()Marks code path as impossible; reaching it results in undefined behavior and enables aggressive optimizations.expect(value, expected)Provides branch prediction hint by indicating the expected value of a condition.likely(bool)Marks a branch as likely to be taken (branch prediction hint).unlikely(bool)Marks a branch as unlikely to be taken (branch prediction hint).typeof(Expression)Returns the type of an expression at compile time without evaluating it.
