| keyword | Is an option for enhanced debugging. Possible values are: | |
| [no]inline_debug_info | Determines whether enhanced debug information is produced for inlined code. | |
| [no]semantic_stepping | Determines whether enhanced debug information useful for breakpoints and stepping is produced. | |
| [no]variable_locations | Determines whether enhanced debug information useful in finding scalar local variables is produced. | |
| extended | Enables all the other debug options. | |
| OFF | No enhanced debugging information is produced. |
This option specifies settings that enhance debugging.
To use this option, you must also specify the -g option.

Description |
|---|---|
| -debug inline_debug_info | Produces enhanced debug information for inlined code. It provides more information to debuggers for function call traceback. The IntelŪ Debugger (IDB) has been enhanced to use richer debug information to show simulated call frames for inlined functions. |
| -debug semantic_stepping | Produces enhanced debug information useful for breakpoints
and stepping. It tells the debugger to stop only at machine instructions that achieve the final effect of a source statement. For example, in the case of an assignment statement, this might be a store instruction that assigns a value to a program variable; for a function call, it might be the machine instruction that executes the call. Other instructions generated for those source statements are not displayed during stepping. |
| -debug variable_locations | Produces enhanced debug information useful in finding scalar
local variables. It uses a feature of the Dwarf object module known as "location lists". This feature allows the run-time locations of local scalar variables to be specified more accurately; that is, whether, at a given position in the code, a variable value is found in memory or a machine register. The Intel Debugger (IDB) is able to process location lists and display local variable values with greater accuracy at run-time. |
| -debug extended | Sets the debug options: inline_debug_info, semantic_stepping, and variable_locations. |
| -debug inline_debug_info | Linux: -inline-debug-info Windows: None |
