gdb/ChangeLog (Jerome Guitton, Joel Brobecker):
* ravenscar-thread.c, ravenscar-thread.h, ravenscar-sparc-thread.c:
New files.
* configure.tgt (sparc-*-*): Add ravenscar-thread.o and
ravenscar-sparc-thread.o to gdb_target_obs.
This is a fairly simple patch that we have had for a while. LynxOS has
relatively few features, from a GDB perspective, and we've been using
a bareboard x86 debugger as our LynxOS cross-debugger. So here is a patch
that make x86-lynxos an alias of bareboard x86.
On the other end of things, I'm still working on gdbserver support
for LynxOS - I'm just lacking the time to make significant progress.
But this is in the works (in the meantime, we're using gdbserver from
gdb-6.8 which is derived work from LinuxWorks' patch).
I wasn't sure whether this would be interesting or not for the FSF tree,
but since it's simple and unintrusive, I am suggesting it now... Any
objection? I wasn't sure whether it warranted a NEWS entry either, since
it doesn't really add a new port, just an alias. I suggest the NEWS entry
when I'm finally done with the gdbserver port.
