Debugging programs that have been dynamically linked against an uninstalled glibc requires unusual steps, such as letting gdb know where the thread db library is located and explicitly calling the loader. However, when the program under test is statically linked, these steps are not required (as a matter of fact, using the dynamic loader to run a statically linked program is wrong and will fail), and gdb should be called the usual way. This patch modifies debugglibc.sh so that it checks if the program under test is statically linked, then runs the debugger appropriately. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

Options:

-h, --help
|

Prints this message and leaves.
|

|
||
The following options require one argument:
|
||
|
||
-b, --breakpoint
|
||
Breakpoints to set at the beginning of the execution
|
||
(each breakpoint demands its own -b option, e.g. -b foo -b bar)
|
||
-e, --environment-variable
|
||
Environment variables to be set with 'exec-wrapper env' in GDB
|
||
(each environment variable demands its own -e option, e.g.
|
||
-e FOO=foo -e BAR=bar)
|
||
|
||
The following options do not take arguments:
|
||
|
||
-c, --in-container
|
||
Run the test case inside a container and automatically attach
|
||
GDB to it.
|
||
-i, --no-direct
|
||
Selects whether to pass the --direct flag to the program.
|
||
--direct is useful when debugging glibc test cases. It inhibits the
|
||
tests from forking and executing in a subprocess.
|
||
Default behaviour is to pass the --direct flag, except when the
|
||
program is run with user specified arguments using the "--" separator.
|
||
-s, --no-symbols-file
|
||
Do not tell GDB to load debug symbols from the program.
