public class SettingsDelayedBranchingAction
extends GuiAction

Action class for the Settings menu item to control delayed branching. Note: Changing this setting while the current program is runnable (assembled, or stepped execution) or terminated triggers a re-assembly. This is necessary to maintain consistency because the machine code assembled for branch instructions differs depending on this setting -- would branch to incorrect address if setting were changed between assembly and execution. Note: This action is disabled while the MIPS program is running. The user need only pause or stop execution to re-enable it.
