This also renames it to make it clearer that this is not a cheap
function (to compute_and_set_names). Also renames name to m_name
to make the implementation of the renamed function more readable.
Most of the places that access sym->m_name directly were also changed
to call linkage_name () instead, to make it clearer which name they
are accessing.

Just some code cleanup. This change has a few benefits:
- Shorter argument list in the functions
- If the caller needs to calculate the string, they no longer
need to explicitly call strlen
- It is easy to pass std::string to this (done in one place
currently)
This also updates a couple of places that were passing 0/1 to
a bool parameter.

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.
When one steps with "next" past the 'main's 'return' statement
in MinGW programs built by mingw.org's tools, PC lands in a
function whose symbol is not in any symtab. GDB then looks
up the nearest symbol, and should find none, because all those
with addresses below PC are not real functions. Having
unresolved symbols, whose address is zero, in minsyms tricked
GDB into using these bogus symbols, which then caused
assertion violation and internal_error. See the discussion at
https://sourceware.org/ml/gdb-patches/2018-12/msg00176.html
for more details.
gdb/ChangeLog
2018-12-28 Eli Zaretskii <eliz@gnu.org>
* coffread.c (coff_symtab_read): Don't record in minsyms symbols
that are unresolved. This avoids triggering an internal error
when stepping outside of 'main' in MinGW programs.
This fixes all the straightforward -Wshadow=local warnings in gdb. A
few standard approaches are used here:
* Renaming an inner (or outer, but more commonly inner) variable;
* Lowering a declaration to avoid a clash;
* Moving a declaration into a more inner scope to avoid a clash,
including the special case of moving a declaration into a loop header.
I did not consider any of the changes in this patch to be particularly
noteworthy, though of course they should all still be examined.

This avoids a couple of uninitialized warnings from gcc by

This introduces a new header, buildsym-legacy.h, and changes all the
symbol readers to use it. The idea is to put the function-based
interface, that relies on the buildsym_compunit global, into a
separate header. Then when a symbol reader is updated to use the new
interface, it can simply not include buildsym-legacy.h, so it's easy
to be sure that the new API is used everywhere.

This moves the context stack globals to be members of
buildsym_compunit, changing the type to a std::vector in the process.
Because the callers expect the context stack object to be valid after
being popped, at Simon's suggestion I've changed pop_context to return
the object rather than the pointer.

PR gdb/18624 concerns an assertion failure that occurs when setting a
breakpoint in a Go program on Windows.
What happens here is that coff_symtab_read uses buildsym but does not
instantiate scoped_free_pendings. So, the struct pending objects are
never released. Later, dwarf2read.c calls buildsym_init, which
asserts.
This patch fixes the problem by instantiating scoped_free_pendings in
coff_symtab_read.

* coffread.c (coff_symfile_finish): Update.
* xcoffread.c (xcoff_symfile_finish): Update.
* elfread.c (elf_symfile_finish): Update.
* symfile.h (dwarf2_free_objfile): Don't declare.
* dwarf2read.c (_initialize_dwarf2_read): Use
register_objfile_data_with_cleanup.
(dwarf2_free_objfile): Now static. Change signature.
TYPE_TAG_NAME has been an occasional source of confusion and bugs. It
seems to me that it is only useful for C and C++ -- but even there,
not so much, because at least with DWARF there doesn't seem to be any
way to wind up with a type where the name and the tag name are both
non-NULL and different.
So, this patch removes TYPE_TAG_NAME entirely. This should save a
little memory, but more importantly, it simplifies this part of gdb.
A few minor test suite adjustments were needed. In some situations
the new code does not yield identical output to the old code.

This patch fixes the subset of -Wimplicit-fallthrough warnings that I
considered obvious. In most cases it was obvious from context that
falling through was desired; here I added the appropriate comment. In
a couple of cases it seemed clear that a "break" was missing.

This patch makes the find_separate_debug_file* functions return
std::string, which allows to get rid of some manual memory management
and one cleanup.
