brtrue.s target

brinst.s target

Branch to a target instruction at the specified offset if non-zero (true), short form.

The stack transitional behavior, in sequential order, is:

  1. value is pushed onto the stack by a previous operation.

  2. value is popped from the stack; if value is true, branch to target.

The brtrue.s instruction transfers control to the specified target instruction if value (type native int) is nonzero (true). If value is zero (false) execution continues at the next instruction.

If value is an object reference (type O) then brinst (an alias for brtrue) transfers control if it represents an instance of an object (for example, if it is not the null object reference; see Ldnull).

The target instruction is represented as a 1-byte signed offset from the beginning of the instruction following the current instruction.

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.

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