With this patch, functions which execute blocking syscalls on Fiasco.OC
are built with frame pointers to get a correct backtrace shown in GDB.
Also, the backtrace test for a thread currently executing a syscall now
traces the 'Genode::Thread_base::join()' function instead of
'Genode::sleep_forever()', because base-nova has a custom implementation
of 'Genode::sleep_forever()' with a different backtrace than on Fiasco.OC.
Fixes#1061.
This patch moves the GDB commands to set a breakpoint in the 'main()'
function into a separate file that can be included from other run scripts.
Fixes#876.
This patch allows to configure the amount of RAM that GDB monitor should
preserve for itself. The configuration syntax looks as follows:
<start name="gdb_monitor">
<resource name="RAM" quantum="1G"/>
<config>
<target name="noux">
<preserve name="RAM" quantum="2M"/>
...
</config>
</start>
Fixes#190.
The following features are tested (currently on Fiasco.OC only):
- breakpoint in 'main()'
- breakpoint in a shared library function
- stack trace when not in a syscall
- thread info
- single stepping
- handling of segmention fault exception
- stack trace when in a syscall
This patch fixes#105.
