This commits the result of running gdb/copyright.py as per our Start
of New Year procedure...
gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.

gdb/ChangeLog:
Update copyright year range in all GDB files.
|
|
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.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.

The lambda function used to sort the enumerator list does not work
properly. This list consists of tuples, (enum label, enum value). The
key function returns x.enumval. enumval not being defined for a tuple,
we see this exception in the test log:
Python Exception <class 'AttributeError'> 'tuple' object has no attribute 'enumval'
The function should return the second item of the tuple, which is the
enumval.
The pretty-printer still worked mostly correctly, except that the
enumeration values were not sorted. The test still passed because the
enumeration values are already sorted where they are defined. The test
also passed despite the exception being printed, because the right output
was printed after the exception:
print (enum flag_enum) (FLAG_1)
Python Exception <type 'exceptions.AttributeError'> 'tuple' objecthas no attribute 'enumval':M
$7 = 0x1 [FLAG_1]
(gdb) PASS: gdb.python/py-pp-maint.exp: print FLAG_1
New in v2:
- Improved test case, I stole Pedro's example directly. It verifies
that the sorting of enumerators by value works, by checking that
printing FOO_MASK appears as FOO_1 | FOO_2 | FOO_3.
I noticed that I could change the regexps to almost anything and the
tests would still pass. I think it was because of the | in there. I
made them more robust by using string_to_regexp. I used curly braces
{ } instead of quoting marks " " for strings, so that I could use
square brackets [ ] in them without having to escape them all. I also
removed the "message" part of the tests, since they are redundant with
the command, and it's just more maintenance to have to update them.
Tested with Python 2.7 and 3.5.

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.
