0f2cd53cf4 [gdb/testsuite] Handle missing .note.GNU-stack
On openSUSE Tumbleweed I run into this for the dwarf assembly test-cases, and
some hardcoded assembly test-cases:
...
 Running gdb.dwarf2/fission-absolute-dwo.exp ...
 gdb compile failed, ld: warning: fission-absolute-dwo.o: \
   missing .note.GNU-stack section implies executable stack
 ld: NOTE: This behaviour is deprecated and will be removed in a future \
   version of the linker

                 === gdb Summary ===

 # of untested testcases         1
...

Fix the dwarf assembly test-cases by adding the missing .note.GNU-stack in
proc Dwarf::assemble.

Fix the hard-coded test-cases using this command:
...
$ for f in $(find gdb/testsuite/gdb.* -name *.S); do
    if ! grep -q note.GNU-stack $f; then
      echo -e "\t.section\t.note.GNU-stack,\"\",@progbits" >> $f;
    fi;
  done
...

Likewise for .s files, and gdb/testsuite/lib/my-syscalls.S.

The idiom for arm seems to be to use %progbits instead, see commit 9a5911c08be
("gdb/testsuite/gdb.dwarf2: Replace @ with % for ARM compatability"), so
hand-edit gdb/testsuite/gdb.arch/arm-disp-step.S to use %progbits instead.

Note that dwarf assembly testcases use %progbits as decided by proc _section.

Tested on x86_64-linux.

42a4f53d2b 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.

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.

e8d054800a [dwarf] Anonymous nested function causes SEGV during psymbol read
According to the DWARF3 standard, a function always has a name attribute
(Section 3.3 - Subroutine and Entry Point Entries).  The only exception
is when a DW_AT_abstract_origin attribute is provided, in which case
the name may be inherited from the referenced DIE.

The problem occured because our compiler generated a subprogram DIE
for a nested function where the name attribute was missing (and no
abstract-origin either).  Our code in add_partial_symbol is not
prepared to deal with the situation, and happily just tries  to compute
the length of the (NULL) function name.

This normally cannot happen, because there is already a guard in
scan_partial_symbols, where we (silently!) ignore anonymous dies,
including anonymous subprograms. Unfortunately, there is a flaw that
affects Ada and other languages that allow nested subprograms. For
nested subprograms, we do not go through scan_partial_symbols and
thus we are missing the name check.

This patch adds the name check in the nested subprogram case. It also
adds a complaint which is emitted during the psymtab->symtab conversion
phase.

gdb/ChangeLog:

        * dwarf2read.c (add_partial_subprogram): Make sure the subprogram
        DIE has a name before creating the associated partial symbol.
        (read_func_scope): Emit a complaint if the subprogram does not
        have a name or when we can't extract the subprogram PC bounds.

gdb/testsuite/ChangeLog:

        * gdb.dwarf2/dw2-anonymous-func.S: New file.
        * gdb.dwarf2/dw2-anonymous-func.exp: New testcase.

Tested on x86_64-linux, no regression.  Note that the testcase also
verifies that the psymtab->symtab conversion does not crash (this is
the purpose of the "list file1.txt:1" test.
