beq.s target

Branch to the target instruction at offset target if equal, short form

The stack transitional behavior, in sequential order, is:

  1. value1 is pushed onto the stack.

  2. value2 is pushed onto the stack.

  3. value2 and value1 are popped from the stack; if value1 is equal to value2, the branch operation is performed.

The beq.s instruction transfers control to the specified target instruction if value1 is equal to value2. The effect is the same as performing a ceq instruction followed by a brtrue branch to the specific target instruction. The target instruction is represented as a 1-byte signed offset from the beginning of the instruction following the current instruction.

The acceptable operand types are encapsulated below:

If the target instruction has one or more prefix codes, control can only be transferred to the first of these prefixes.

Control transfers into and out of try, catch, filter, and finally blocks cannot be performed by this instruction (such transfers are severely restricted and must use the Leave instruction instead).

The following Emit method overload can use the beq.s opcode:
