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.
IDB has two command language interfaces:
dbx
gdb (default)
For complete information about IDB, see the idb man page or the online Intel® Debugger (IDB) Manual.
