Most of the symbol readers have code to iterate over a partial symtabs
dependencies, expanding each one and optionally printing a message.
Now that the "second-stage" psymtab expansion is available as a
method, these implementations can all be merged.
This patch also changes a couple more warnings into assertions.

The symbol readers generally used two functions to expand a partial
symtab: an outer function (now the "read_symtab" method), and an inner
function, typically named something like "psymtab_to_symtab".
This patch changes this second step to be a method on partial_symtab,
and updates all the callers. For legacy_psymtab, a new function
pointer member is introduced.
This patch enables a subsequent cleanup.

Each symbol reader implemented its own "Reading..." messages, and most
of them double-checked that a previously-expanded psymtab could not be
re-read.
This patch consolidates the message-printing, and changes these checks

This introduces a new partial_symtab::read_symtab method, and updates
the symbol readers to subclass partial_symtab and implement this
method. The old read_symtab and read_symtab_private members are
removed.
In practice, only DWARF and CTF are truly updated to take advantage of
the new setup. The other symbol readers are less actively maintained,
and so this patch also introduces a "legacy_psymtab", which
essentially works the same way as the old partial_symtab.
(Note that, without more knowledge of the interaction between these
symbol readers, fixing this to remove the new (small) overhead is not
trivial, because these readers copy the read_symtab pointer between
partial symtabs.)

This is the next step in getting the symbol readers to allocate
psymtabs themselves: change allocate_psymtab to be an ordinary
constructor, and then use "new" at the previous call sites. Note that

allocating a partial symtab.

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 changes add_psymbol_to_list to use an enum, rather than a pointer

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 patch finally makes partial symbols and partial symtabs
independent of the program space.
Specifically:
It changes add_psymbol_to_list to accept a section index, and changes
the psymbol readers to pass this. At the same time it removes the
code to add the objfile's section offset to the psymbol.
It adds an objfile argument to the psymtab textlow and texthigh
accessors and changes some code to use the raw variants instead.
It removes the "relocate" method from struct quick_symbol_functions,
as it is no longer needed any more.
It changes partial_symbol::address so that the relevant offset is now
applied at the point of use.

Update.
Right now some psymtab code checks whether a psymtab's textlow or
texthigh fields are valid by comparing against 0.
I imagine this is mildly wrong in the current environment, but once
psymtabs are relocated dynamically, it will no longer be correct,
because it will be much more normal to see a psymtab with a textlow of
zero -- this will just mean it appears at the start of the text
section.
This patch introduces validity bits to handle this situation more
nicely, and changes users of the code to follow.

This introduces accessors for the partial symbol table textlow and
texthigh fields. This lets us later arrange to relocate these values
at their point of use.
I did this conversion by renaming the fields. I didn't rename the
fields back afterward, thinking that on the off chance that someone
has a patch touching this area, then a merge would helpfully break
their compile.
I looked at making the fields private, but this interferes with the
memset in allocate_psymtab, and I didn't want to chase this down.
This conversion can be done later if need be.

texthigh fields.
(scan_xcoff_symtab): Update.
I noticed that there is a bit of dead code in end_psymtab.
This deletes it.
Normally I would investigate a fix for the code. However, considering
that the code has been this way a long time (since the first import to
sourceware) and considering that dbxread.c is not as important any
more, I think it's safe to just consider that there's no bug.

* dbxread.c (end_psymtab): Remove dead code.
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.

buildsym-legacy.c.
* Makefile.in (HFILES_NO_SRCDIR): Add buildsym-legacy.h.
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.

(read_func_scope, read_lexical_block_scope): Update.
* dbxread.c (process_one_symbol): Update.

(outermost_context_p, get_current_context_stack)
(get_context_stack_depth): Declare.
(pop_context): Return struct context_stack.
* buildsym.c (struct buildsym_compunit) <m_context_stack: New
member.

(pop_context): Return struct context_stack.
(outermost_context_p, get_current_context_stack)

(buildsym_init): Update.
This changes a few explicit checks of context_stack_depth to use
outermost_context_p instead. This simplifies some future work.

* xcoffread.c (read_xcoff_symtab): Use outermost_context_p.

outermost_context_p.
* dbxread.c (process_one_symbol): Use outermost_context_p.
* coffread.c (coff_symtab_read): Use outermost_context_p.
free_pending_blocks can be static because scoped_free_pendings (et al)
arrange for it to be NULL in the "steady state". This removes a
couple of unnecessary calls to free_pending_blocks and changes it to
be static.
gdb/ChangeLog
2018-07-16 Tom Tromey <tom@tromey.com>
* xcoffread.c (xcoff_initial_scan): Don't call
free_pending_blocks.

* buildsym.c (scoped_free_pendings::scoped_free_pendings): New.
(free_pending_blocks): Now static.
buildsym_new_init is just an alias for buildsym_init. This removes
it. In the long run buildsym_init will also go away; this patch just
helps make things a bit clearer in the meantime.

processing_acc_compilation is only used in dbxread.c, so move it
there.

I get this kind of errors with GCC 6.3.0:
/home/simark/src/binutils-gdb/gdb/breakpoint.c: In function 'void print_solib_event(int)':
/home/simark/src/binutils-gdb/gdb/breakpoint.c:4618:12: error: types may not be defined in a for-range-declaration [-Werror]
for (struct so_list *iter : current_program_space->added_solibs)
^~~~~~
Removing the struct keyword makes it happy.
gdb/ChangeLog:
* breakpoint.c (print_solib_event, check_status_catch_solib):
Remove struct keyword in range-based for loops.
* dbxread.c (find_corresponding_bincl_psymtab): Likewise.
* dwarf2read.c (compute_delayed_physnames, rust_union_quirks);
Likewise.
* linespec.c (find_superclass_methods, search_minsyms_for_name):
Likewise.
* symfile.c (addr_info_make_relative): Likewise.
* thread.c (value_in_thread_stack_temporaries): Likewise.
This removes the remaining cleanups from dbxread.c, via std::vector,
scoped_restore, and unique_xmalloc_ptr.
Tested by the buildbot.
