This patch is another attempt to fix PR cli/19551. Unlike my previous
attempt, it doesn't print progress. Instead, it just changes some
messages and adds newlines to make the output a bit nicer.
It also removes the "done." text that was previously emitted. The
idea here is that it is obvious when gdb is done reading debug info,
as it starts then doing something else; and that while this message
did not provide much benefit to users, it did make it harder to make
the output clean.
After this change the output from "./gdb -iex 'set complaint 1' -nx ./gdb"
reads:
Reading symbols from ./gdb...

If all sections of a symbol file are loaded with a fixed offset, it
is easier to specify that offset than listing all sections
explicitly. There is also a similar option for "symbol-file".
gdb/ChangeLog:
2018-06-28 Petr Tesarik <ptesarik@suse.cz>
* symfile.c (add_symbol_file_command, _initialize_symfile): Add
option "-o" to add-symbol-file-load to add an offset to each
section's load address.

The (first) .text section must be always specified as the second
non-option argument. The documentation states that GDB cannot
figure out this address by itself. This is true if the object file
was indeed relocated, but it is also confusing, because all other
sections can be omitted and will use the address provided by BFD.

This is a bug that's been detected while doing the readnever work.
If you use 'symbol-file' or 'add-symbol-file', the position of each
argument passed to the command matters. This means that if you do:
(gdb) symbol-file -readnow /foo/bar
The symbol file specified will (correctly) have all of its symbols
read by GDB (because of the -readnow flag). However, if you do:
(gdb) symbol-file /foo/bar -readnow
GDB will silently ignore the -readnow flag, because it was specified
after the filename. This is not a good thing to do and may confuse
the user.
To address that, I've modified the argument parsing mechanisms of
symbol_file_command and add_symbol_file_command to be
"position-independent". I have also added one error call at the end
of add_symbol_file_command's argument parsing logic, which now clearly
complains if no filename has been specified. Both commands now
support the "--" option to stop argument processing.
This patch provides a testcase for both commands, in order to make
sure that the argument order does not matter. It has been
regression-tested on BuildBot.
gdb/ChangeLog:
2017-12-01 Sergio Durigan Junior <sergiodj@redhat.com>
* symfile.c (symbol_file_command): Call
'symbol_file_add_main_1' only after processing all command
line options.
(add_symbol_file_command): Modify logic to make arguments
position-independent.
gdb/testsuite/ChangeLog:
2017-12-01 Sergio Durigan Junior <sergiodj@redhat.com>
* gdb.base/relocate.exp: Add tests to guarantee that arguments
to 'symbol-file' and 'add-symbol-file' can be
position-independent.
This patch updates add-symbol-file help and error text.
It changes add-symbol-file to throw an exception if "-s" is seen but
not all of the arguments are given. Previously this was silently
ignored.
It changes the unrecognized argument message to more clearly state
what went wrong.
Finally, it updates the usage line in the help text to follow GNU
style regarding "metasyntactic variables"; a change I believe should
be made to all gdb help messages.

2017-11-29 Tom Tromey <tom@tromey.com>

Update copyright year range in all GDB files.

* gdb.base/relocate.exp: Check that invalid options are
rejected.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
* Makefile.in (symfile.o): Add $(exec_h).
* exec.h (exec_set_section_address): Add prototype.
* exec.c (exec_set_section_address): New function.
* symfile.c: Include "exec.h".
(struct place_section_arg, place_section): New.
