Debugging with GDB Manual HP WDB v6.3 (5900-2180, August 2012)

The set inline-debug on command enables the inline debugging feature without the inline
breakpoints options in Integrity systems. This command is enabled by default.
The set inline-debug off command disables the inline debugging feature. You can disable
inline debugging by entering this command before attaching the debugger to the application.
The set inline-debug inline_bp_all command enables you to set and modify break-
points on all instances of a particular inline function. It also enables the inline debugging feature.
A single instance of the specified inline function is displayed as a representative in- stance for all
the instances of the specified inline function. This creates a single-breakpoint illusion for multiple
instances of the inline function. You can set and modify breakpoints on all the instances of the
inline functions by setting and modifying breakpoints on the displayed instance of the inline function.
You must enter this command before attaching the debugger to the application.
The set inline-debug inline_bp_individual command enables you to set and modify
breakpoints on a specific instance of an inline function. It also enables the inline debugging feature.
All instances of the inline function are displayed separately with individual breakpoint occurrences.
You can set or delete individual breakpoints on a specific instance of an inline function without
modifying the breakpoints on other instances of the inline function. You must enter this command
before attaching the debugger to the application.
Limitations:
• The inline breakpoint features are not available for programs that are com- piled with +O2
optimization level and above.
• The inline breakpoint features can degrade performance of the application that is being
debugged. You can explicitly disable the breakpoint features when the features are not required
and continue to use other inline debugging features, such as step and next.
14.8.2.1 Debugging Inline Functions in Integrity Systems
To debug inline functions in Integrity systems, complete the following steps:
1. The application must be compiled with the -g option for inline debugging. No additional
options are required. For example:
/opt/aCC/bin/aCC -g test.c
2. Inline debugging without the breakpoint feature is enabled by default. You can modify the
inline debugging settings by toggling the options for the set inline- debug command.
• To enable inline debugging without inline breakpoint support, enter either of the following
commands:
(gdb) set inline-debug on
or
$ gdb --inline = on
• To set and modify breakpoints collectively on all instances of inline functions and enable
inline debugging, enter either of the following commands:
(gdb) set inline-debug inline_bp_all
or
$ gdb --inline = inline_bp_all
• To set and modify individual breakpoints on specific instances of inline functions and
enable inline debugging, enter either of the following commands be- fore debugging the
application:
(gdb) set inline-debug inline_bp_individual
or
$ gdb --inline = inline_bp_individual
• To disable inline debugging, enter either of the following commands be- fore debugging
the application:
