Debugging assembler routines

Use the Disassembly view to debug assembler routines. Because assembler routines have no debug information, the debugger automatically goes to this view.

Set a breakpoint at a disassembled statement in the Disassembly view by double-clicking in the prefix area. By default, the debugger when it starts runs until it hits the first debuggable statement. To cause the debugger to stop at the very first instruction in the application (debuggable or not), you must use the -i option. For example:

idebug -i progname
