Exits a protected region of code, unconditionally tranferring control to a target instruction (short form).

The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
|DE < int8 >||leave.s target||Exit a protected region of code, short form.|
There is no stack transition behavior specified for this instruction.
The leave.s instruction unconditionally transfers control to the passed target instruction, represented as a 1-byte signed offset from the beginning of the instruction following the current instruction.
The leave.s instruction is similar to the br instruction, but it can be used to exit a try, filter, or catch block whereas the ordinary branch instructions can only be used in such a block to transfer control within it. The leave.s instruction empties the evaluation stack and ensures that the appropriate surrounding finally blocks are executed.
You cannot use a leave.s instruction to exit a finally block. To ease code generation for exception handlers it is valid from within a catch block to use a leave.s instruction to transfer control to any instruction within the associated try block.
If an instruction has one or more prefix codes, control can only be transferred to the first of these prefixes.
The following Emit constructor overload can use the leave.s opcode:
