Introduction to the Intel® Debugger (idb)

The Intel® Debugger (idb) is a source-level, symbolic debugger that lets you:

• Control the execution of a program at the source line level.

• Set stops (breakpoints) at specific source lines or under various conditions.

• Change the value of variables in your program.

• Refer to program locations by their symbolic names, using the debugger's knowledge of the Intel® Fortran language to determine the proper scoping rules and how the values should be evaluated and displayed.

• Print the values of variables and set a tracepoint (trace) to notify you when the value of a variable changes. (Another term for a tracepoint is a watchpoint.)

• Perform other functions, such as examining core files, examining the call stack, or displaying registers.

The idb debugger has two modes:

• dbx (default mode)

• gdb (optional mode)

All examples in this guide are shown in dbx mode.
