gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.
If 'complaint' is used in a namespace context, it will fail because
'stop_whining' is only declared at the top level. This patch fixes
this problem in a simple way, by moving the declaration of
'stop_whining' out of the macro and to the top-level.

* complaints.h (stop_whining): Declare at top-level.
(complaint): Don't declare stop_whining.
This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.
This removes the SHORT_FIRST_MESSAGE case from complaints, leaving
only a single case. This allows for the removal of the last argument
to clear_complaints, and also simplifies complaint_internal, removing
an extra allocation in the process.
After this, the "./gdb -iex 'set complaint 1' -nx ./gdb" example will
show:
Reading symbols from ./gdb...
During symbol reading: .debug_ranges entry has start address of zero [in module /home/tromey/gdb/build/gdb/gdb]
During symbol reading: DW_AT_low_pc 0x0 is zero for DIE at 0x17116c1 [in module /home/tromey/gdb/build/gdb/gdb]
During symbol reading: .debug_line address at offset 0xa22f5 is 0 [in module /home/tromey/gdb/build/gdb/gdb]
During symbol reading: unsupported tag: 'DW_TAG_unspecified_type'
During symbol reading: const value length mismatch for 'std::ratio<1, 1000000000>::num', got 8, expected 0
This is a bit wordier but, I think, a bit more clear, as the form of
the message no longer depends on precisely when it was emitted. In
particular if you compare to the output from the 'Clean up "Reading
symbols" output' patch, you can see that earlier gdb would switch from
the prefix-less form to the "During symbol reading" form at a point
that is meaningless to the user (specifically, after psymtab reading
is done and gdb tries to expand a CU).

* gdb.cp/maint.exp (test_invalid_name): Update expected output.
* gdb.gdb/complaints.exp (test_short_complaints): Remove.
(test_initial_complaints, test_empty_complaints): Update.
* gdb.dwarf2/dw2-stack-boundary.exp: Update.
There were a couple of leftovers from earlier patches in
complaints.[ch]. This removes them.
gdb/ChangeLog
2018-10-04 Tom Tromey <tom@tromey.com>
* complaints.h (struct complaints): Remove declaration.
* complaints.c (clear_complaints): Remove an unused variable.
After the previous patch, the "noisy" parameter to clear_complaints is
no longer used, so this patch removes it.

* complaints.c (clear_complaints): Remove "noisy" parameter.

* gdb.gdb/complaints.exp (test_empty_complaints): Update.
I happened to notice that gdb has both complaint_internal and
internal_complaint. The latter is unused, so this patch removes it.

* complaints.c (internal_complaint): Remove.
* complaints.h (internal_complaint): Remove.

The problem is that we're always computing the arguments to pass to
complaint, including passing the format strings through gettext, even
when complaints are disabled. As seen above, gettext can be quite
expensive.
Fix this by wrapping complaint in a macro that skips the real
complaint call when complaints are disabled.
This improves "gdb -nx -readnow -batch gdb" from
~11.0s => ~7.8s with -O2 -g3, and
~6.0s => ~5.3s with -O2 -g.
w/ gcc 5.3.1, on x86_64, for me.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
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.
* complaints.c (complain): Made into a varargs function.
* complaints.h: New file, code moved from symfile.h.
* Makefile.in (SFILES_MAINDIR): Add complaints.c.
* Makefile.in (HFILES): Add complaints.h.
* Makefile.in (OBS): Add complaints.o.
* symfile.c (complaint_root, stop_whining, complaint_series,
complain, clear_complaints, add_show_from_set for stop_whining):
Moved to complaints.c.
* symfile.h (struct complaint, complaint_root decl, complain
prototype, clear_complaints prototype): Moved to complaints.h.
* buildsym.c, coffread.c, dbxread.c, dwarfread.c, elfread.c,
gdbtypes.c, mipsread.c, stbsread.c, symfile.c: Include
complaints.h. Remove casts from arguments to complain(),
which is now a varargs function, and remove unnecessary
placeholder zero args.
* defs.h (begin_line): Add prototype.
* defs.h (vprintf_filtered): Add prototype.
* dwarfread.c (varargs.h): Remove, no longer needed.
* dwarfread.c (dwarfwarn): Remove prototype and function.
* dwarfread.c (complaints): Define a bunch of complaints.
* dwarfread.c (SQUAWK): Remove macro defs, convert all
usages to standard complain() calls.
* utils.c (begin_line): New function that ensures that
whatever gets filter-printed next starts on its own line.
* utils.c (vprintf_filtered): New func, like vfprintf_filtered,
but to stdout (calls vfprintf_filtered internally).
