iflt : jump if less than zero : index : visitJumpInsn()

Description

iflt pops the top int off the operand stack. If the int is less than zero, execution branches to the address (pc + branchoffset), where pc is the address of the iflt opcode in the bytecode and branchoffset is a 16-bit signed integer parameter following the ifeq opcode in the bytecode. If the int on the stack is greater than or equal to zero, execution continues at the next instruction.

If you are using Jasmin, branchoffset is computed for you from the address of <label>.

Example

    iload_1         ; push the int value in local variable 1 onto the stack
    iflt Label      ; if the value on the stack is below zero, jump to Label
    return          ; return if local variable 1 is greater than or equal to zero
Label:
    ; execution continues here if local variable 1 is less than zero...

Notes

Addresses are measured in bytes from the start of the bytecode (i.e. address 0 is the first byte in the bytecode of the currently executing method).
