ifge : jump if greater than or equal to zero : index : visitJumpInsn()

Description

ifge pops the top int off the operand stack. If the int is greater than or equal to zero, execution branches to the address (pc + branchoffset), where pc is the address of the ifge opcode in the bytecode and branchoffset is a 16-bit signed integer parameter following the ifge opcode in the bytecode. If the int on the stack is less than 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
    ifge Label      ; if the value on the stack is >= 0, jump to Label
    return          ; return if local variable 1 is less than zero
Label:
    ; execution continues here if local variable 1 is greater than or equals 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).
