The MULTI® Source-level Debugger is a powerful windowing debugger that enables program loading, execution, run control, and monitoring. MULTI provides debugging in C, C++, Embedded C++, Ada 95, Fortran, and assembly. MULTI's basic functions are intuitive and easy to use; programmers spend less time learning the tools and more time generating code. MULTI contains advanced features for viewing data during execution, easy direct links to the MULTI Project Builder, Text Editor, Class Browser, Run-time Error Checking, and Performance Profiler, customizable menus and command buttons, and an open interface to editors and version control software of choice. The Main Debugger Window The main debugger window consists of three panes, as shown to the right. The upper pane is the index pane, which contains navigational buttons. Below that is the source pane, which displays the program source. The bottom pane is the command pane, which is used to enter typed commands and display the results of commands. |

Extensive C++ Support MULTI is a true C++ development environment with C++ support seamlessly integrated at every level. MULTI's Source-level Debugger evaluates C++ expressions and understands C++ namespace resolution, overloaded function resolution, and copy constructors and coercion operators. Casts and coercions are performed implicitly, and ambiguities regarding overloaded operators and functions are automatically resolved. MULTI is fully aware of the complex features of the C++ language. This makes it unnecessary to mentally translate C++ constructs into the mechanisms used by the compiler. Taking full advantage of MULTI's new advanced Incremental Debug format and improved processing of C++ symbol information, MULTI has implemented several advanced C++ debugging capabilities, including:  Full namespace debugging supportC++ function navigation with ambiguity resolutionAdvanced class browsingDebugging of C++ exception throws and long jumpsDisplaying C++ Objects The same powerful display capabilities available for viewing variables in a C program have been extended to fully support the display of C++ objects. Clicking on the name of a C++ object displays its members in the command pane; double clicking on the name of the C++ object displays its members in a special display window where they can be modified or monitored as the user steps through the program. C++ programmers can access the following important information through MULTI's graphical user interface: C++ inheritance graphsC++ classes, casts and coercionsStatic fields in classesAnonymous unions in classesImplicit 'this' and 'casts'Overload ambiguity resolutionCalling overloaded operators and functionsReferencesTrue object typesTemplate Functions MULTI supports the debugging of template functions. With templates, C++ automatically generates multiple instances of a function, one for each combination of argument types actually used in the program. Every time the function is referenced, the C++ compiler determines which specific function to use, based on the argument types. Memory Viewer MULTI enables the user to view the contents of memory in a flexible and powerful manner. MULTI's 'memview', which can be invoked through a user-defined button or command line statement, provides a full address/contents table of memory that can be formatted in a variety of ways including hexadecimal, decimal, ASCII, binary, real, and many more. Memory regions can be specified symbolically or in terms of absolute or relative addresses. Multiple 'memview' windows can be opened to view several memory regions simultaneously. Invoking an Editor The MULTI Source-level Debugger is aware of and interacts with other components of the MULTI environment. Clicking on the 'Edit' button launches an editor on the current file, with the edit cursor positioned at the current line. Double clicking on the name of a procedure anywhere in the source pane brings up an editor window on the source code for that procedure definition. After making an edit, a single button click will recompile the program and reinitialize the debugger with the new executable. Mixed Language Debugging MULTI supports mixed language debugging in C, C++, Embedded C++, Ada 95, FORTRAN and Assembly. When moving among modules of different languages, MULTI recognizes the language of the currently viewed file and adjusts its expression evaluation and data display accordingly. Also, command line input uses the syntax of the language being debugged. Ada and FORTRAN programmers can enjoy a debugger that understands their language instead of having to struggle through the use of a debugger intended for C programs. For example, arrays may be displayed in either row major order or column major order, according to the conventions of the language. » RTOS » MULTI IDE » AdaMULTI IDE » Compilers » Communications Software » Custom Development | |||||||||||||||||||||||
