if_icmplt : jump if one integer is less than another : index : visitJumpInsn()

Description

if_icmplt pops the top two ints off the stack and compares them. If value2 is less than value1, execution branches to the address (pc + branchoffset), where pc is the address of the if_icmplt opcode in the bytecode and branchoffset is a 16-bit signed integer parameter following the if_icmplt opcode in the bytecode. If value2 is greater than or equal to value1, 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
    bipush 2        ; push the int 2 onto the stack
    if_icmplt Label ; if the value of local variable 1 is <= 2, jump to Label
    return          ; return if local variable 1 is greater than 2
Label:
    ; execution continues here if local variable 1 is less than or equal to 2...

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).
