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 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.
This is just a testcase addition that I am proposing for upstream GDB.
We have this in our internal tree, and the related RH bug is:

This bug is about a global variable that got incorrectly displayed by
GDB. This bug has already been fixed a long time ago by Joel's
commit:
commit 19630284f570790ebf6d50bfb43caa1f125ee88a

But I think a testcase for it wouldn't hurt.
So, consider the following scenario:
$ cat solib1.c
int test;
void c_main (void)
{
test = 42;
}
$ cat solib2.c
int test;
void b_main (void)
{
test = 42;
}
$ cat main.c
int main (int argc, char *argv[])
{
c_main ();
b_main ();
return 0;
}
$ gcc -g -fPIC -shared -o libSO1.so -c solib1.c
$ gcc -g -fPIC -shared -o libSO2.so -c solib2.c
$ gcc -g -o main -L$PWD -lSO1 -lSO2 main.c
$ LD_LIBRARY_PATH=. gdb -q -batch -ex 'b c_main' -ex r -ex n -ex 'p test' ./main
...
$1 = 0
This happened with GDB before Joel's commit above. Now, things work
and GDB is able to correctly display the nested global variable:
$ LD_LIBRARY_PATH=. gdb -q -batch -ex 'b c_main' -ex r -ex n -ex 'p test' ./main
...
$1 = 42
The testcase attached tests this behavior.
