| Linux and Mac OS: | -debug [keyword] |
| Windows: | None |
| keyword | Is the type of debugging information to be generated. Possible values are: | |
| full | Generates complete debugging information. | |
| all | Generates complete debugging information (same as full). | |
| minimal | Generates line number information for debugging. | |
| none | Disables generation of debugging information. | |
| [no]expr-source-pos | Determines whether source position information at the expression level of granularity is produced. | |
| [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 semantic-stepping and variable-locations. | |
| -debug none | No debugging information is generated. |
This option specifies the type of debugging information generated by the compiler
To use this option, you must also specify the -g option.
| Option | Description |
|---|---|
| -debug full or -debug all |
Generates complete debugging information. This is the default if -debug is specified with no keyword. |
| -debug minimal | Generates line number information for debugging. |
| -debug none | Disables generation of debugging information. |
| -debug expr-source-pos | Produces source position information at the statement level of granularity. |
| -debug inline-debug-info | Produces enhanced debug information for inlined code. It provides more information to debuggers for function call traceback. The Intel® 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 semantic-stepping and variable-locations. |
| -debug inline-debug-info | Linux: -inline-debug-info Mac OS: None Windows: None |
