Available Displays and Data

• Source, assembler, and machine code integrated for ease of reference
• Call stack with subprogram, line, and language
• Task information
• Evaluation of general expressions at breakpoints
• Convenient retrieval of previously evaluated expression

Support for Ada Tasking

• List task information such as status, priority, and parent
• Switch between tasks
• Set task-specific breakpoints

Breakpoint and Watchpoint Support

• Set breakpoint at any line, including within generic instantiations
• Set watchpoint to stop program when value of specified expression changes
• Set conditional breakpoint to stop execution only when specified condition is true
• Run user-specified script of commands at breakpoint
• Single step over source line, over or into subprogram call, or over an assembly language instruction
• Change value of any variable, evaluate any expression, or invoke any subprogram while the program is stopped at a breakpoint
• Resume execution at a different point than where stopped
• Halt execution when any exception, or a specific exception, or an unhandled exception is raised

Assembly Language Debugging Support

• Display/modify registers and memory locations
• Display assembly and machine code, interleaved with Ada source
• Single step and breakpoint on specified assembly instructions
