2010-04-27Associate .dg files to AdaJoel Brobecker2-0/+6
The .dg files are files containing the user's code, after the GNAT expander was applied. The expansion replaces some of the complex features by simpler pseudo-Ada code and the user can ask to see and debug that code using the -gnatDG option... For instance, given the following code where Circle is a tagged type (aka as a class type in C++): procedure Foo is My_Shape : Circle := (X => 1, Y => 2, R => 3); X : Integer; begin X := Position_X (My_Shape); end Foo; The expansion results in: procedure foo is my_shape : pck__circle := ( _parent => ( _tag => pck__circleP, x => 1, y => 2), r => 3); x : integer; begin x := pck__position_x (my_shape); return; end foo; 2010-04-27 Joel Brobecker <brobecker@adacore.com> * symfile.c (init_filename_language_table): Register .dg files with language_ada.
2010-04-27Document special use of target_type field in Ada structs.Joel Brobecker2-0/+8
This is a comment that I wrote not too long ago, I believe, as part of a submission process, and somehow did not get to commit. It explains how the TYPE_TARGET_TYPE is used by Ada in the case of dynamic records/ unions. 2010-04-24 Joel Brobecker <brobecker@adacore.com> * gdbtypes.h (struct main_type): Expand comment about target_type field.
2010-04-27Check library name rather than member name when rereading symbols.Joel Brobecker2-5/+9
On Darwin, we have lots of complaints being emitted when restarting a program: (gdb) start `a-except.o' has disappeared; keeping its symbols. `unwind-dw2.o' has disappeared; keeping its symbols. `s-except.o' has disappeared; keeping its symbols. `s-traceb.o' has disappeared; keeping its symbols. These object files are part of the GNAT runtime, and were never available. The warning comes from the fact that we're checking whether the .o files in the GNAT shared runtime have changed whereas we should be checking whether the GNAT shared library itself has changed. This patch implements this. Although it is really only useful on a platform such as Darwin (debug info stored in .o files), we believe that this is the right thing to do in general. This change should be a noop for all the other platforms in any case. gdb/ChangeLog (from Tristan Gingold & Pedro Alves): * symfile.c (reread_symbols): Also search for file in libraries. Update comment. Tested on x86_64-darwin and x86_64-linux.
2010-04-27Add support for x86-lynxos cross debugger (as bareboard x86).Joel Brobecker2-1/+5
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. gdb/ChangeLog: * configure.tgt: Treat x86-lynxos targets as x86 bareboard targets in terms of configuration.
