This introduces an iterable object which can be used to iterate over
objfiles. It also introduces a generic "next_iterator", which can be
used to iterate over types that have a "next" field.

* common/next-iterator.h: New file.
* objfiles.h (class all_objfiles): New.

This removes ALL_COMPUNIT_FILETABS, replacing its uses with ranged for
loops.
Because this is still used in the ALL_OBJFILE_FILETABS macro, in some
places a declaration had to be removed or renamed to avoid shadowing.

declaration.
* symmisc.c (print_objfile_statistics, dump_objfile)

This removes the ALL_COMPUNITS, replacing its uses with two nested
ranged for loops.
gdb/ChangeLog
2018-11-25 Tom Tromey <tom@tromey.com>
* symtab.c (lookup_objfile_from_block)
(find_pc_sect_compunit_symtab, search_symbols)
(default_collect_symbol_completion_matches_break_on): Use
objfile_compunits.
* objfiles.h (ALL_COMPUNITS): Remove.
* maint.c (count_symtabs_and_blocks): Use objfile_compunits.
* cp-support.c (add_symbol_overload_list_qualified): Use
objfile_compunits.
* ada-lang.c (ada_collect_symbol_completion_matches)
(ada_add_global_exceptions): Use objfile_compunits.

From: Tom Tromey @ 2018-11-25 16:54 UTC (permalink / raw)
To: gdb-patches; +Cc: Tom Tromey
This removes the ALL_MSYMBOLS and ALL_OBJFILE_MSYMBOLS macros,
replacing their uses with ranged for loops.
In a couple of spots, a new declaration was needed in order to work
around shadowing; these are just temporary and are removed in a
subsequent patch.

From: Tom Tromey @ 2018-11-25 16:54 UTC (permalink / raw)
To: gdb-patches; +Cc: Tom Tromey
This removes the ALL_OBJSECTIONS macro, replacing its uses with ranged
for loops.
The special code in this macro for noticing a "break" from the inner
loop was only needed in a single place; so rather than try to
replicate this, I've simply replaced that use with a "goto".
gdb/ChangeLog
2018-11-25 Tom Tromey <tom@tromey.com>
* symfile.c (overlay_invalidate_all, find_pc_overlay)
(find_pc_mapped_section, list_overlays_command)
(map_overlay_command, unmap_overlay_command)
(simple_overlay_update): Use all_objfiles.
* spu-tdep.c (spu_overlay_update): Use all_objfiles.
* printcmd.c (info_symbol_command): Use all_objfiles.
* objfiles.h (ALL_OBJSECTIONS): Remove.
* maint.c (maintenance_translate_address): Use all_objfiles.
* gcore.c (gcore_create_callback): Use all_objfiles.
(objfile_find_memory_regions): Likewise.

From: Tom Tromey @ 2018-11-25 16:54 UTC (permalink / raw)
To: gdb-patches; +Cc: Tom Tromey
This removes the ALL_OBJFILE_PSYMTABS macro, replacing its uses with
ranged for loops.
gdb/ChangeLog
2018-11-25 Tom Tromey <tom@tromey.com>
* dbxread.c (dbx_end_psymtab): Use objfile_psymtabs.
* mdebugread.c (parse_partial_symbols): Use objfile_psymtabs.
* psymtab.c (ALL_OBJFILE_PSYMTABS_REQUIRED): Remove.
(psym_map_symtabs_matching_filename, find_pc_sect_psymtab)
(psym_lookup_symbol, psym_find_last_source_symtab)
(psym_forget_cached_source_info, psym_print_stats)
(psym_expand_symtabs_for_function, psym_expand_all_symtabs)
(psym_expand_symtabs_with_fullname, psym_map_symbol_filenames)
(psym_map_matching_symbols, psym_expand_symtabs_matching)
(psym_find_compunit_symtab_by_address)
(maintenance_print_psymbols, maintenance_info_psymtabs)
(maintenance_check_psymtabs): Use ranged for.
* psymtab.h (class objfile_psymtabs): New.
(require_partial_symbols): Return objfile_psymtabs.
* psympriv.h (ALL_OBJFILE_PSYMTABS): Remove.

This series removes various ALL_* iteration macros, in favor of C++
iterators, range adapters, and ranged for loops. I've been wanting
this for a while, because it helps a little bit with various
experiments of mine that involve changing objfile lifetime management;
Pedro's thread iterator patch prompted me to finally do this.
The main downside of removing these macros is that it involves some
reindentation; and expanding some macros to two nested loops means a
couple somewhat ugly reformattings.
On the plus side, though, this tightens the scope of iteration
variables, which is good. And, it removes some hairy code,
particularly the ALL_OBJSECTIONS patch.
There are still a few more such macros that could be converted. And,
I think inf_threads_iterator could be converted to use next_iterator.
I can do some of this if there's interest.
Regression tested by the buildbot.

To: gdb-patches; +Cc: Tom Tromey
This removes ALL_OBJFILE_COMPUNITS, replacing its uses with ranged for
loops. Because ALL_COMPUNITS is also updated, in some places a
declaration must be deleted to avoid shadowing.

FWIW, this seems like a good change to me; I am particularly
receptive to the fact that the scope of the iteration variables
is now restricted to the loop itself.
As for the downside, I don't consider re-indentation a downside
other than it makes review a bit more painful. The two-nested
loop didn't seem like they were making the code less readable.
Did you have any other concerns with that?
I admit I was scanning the last few patches much faster than the first
few ones, but they seem fairly mechanical to me, so I think the risk
is low.

I think I will have to redo much of the series to account for that
version of gcc that Simon sometimes uses -- the one that requires ranged
for loops to use the "struct" keyword. I probably can't really test
that change but I'll make a best effort at it in order to reduce the
amount of work he has to do.

Hehe. Looking back at those patches, it's with gcc 6.3.0. Those are cross-compilers
I built with crosstool-ng 1.22:
$ ~/x-tools/aarch64-rpi3-linux-gnueabi/bin/aarch64-rpi3-linux-gnueabi-gcc --version
aarch64-rpi3-linux-gnueabi-gcc (crosstool-NG crosstool-ng-1.22.0-677-ga3dd55b9) 6.3.0
I see crosstool-ng 1.23 has been released, but it still uses gcc 6.3.0. And it looks like
the gcc version used in current Debian stable (codename stretch) is also 6.3.0:
https://packages.debian.org/stretch/gcc
I'll give a try to this patchset (and take a quick look at the same time).

Apparently I thought ahead and used the struct tags when I wrote the
patch. Funny that I don't remember that.
I'll push it in some day soon.

Usually, the problem I had was the other way around, that having the struct tag
causes a compilation problem:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=8634679f82df75cf482b0c0814c2b3865da91d22
The recent Hurd problem, however, happened when not using the struct tag
with thread_info...

I did it. A few spots needed an additional tweak to avoid a clash
between a variable ("objfile" or "symtab") and the type.
I've force-pushed it to that same branch, in case you feel like giving
it a try. I'll re-send the series sometime.

When I played with it, the compiler did not complain when I used:
for (objfile *objfile : ...)
That was with gcc 8.2.0. Do you know if it's really problematic with
other compilers/versions?

I gave that a quick look.
I was wondering if you had thought about replacing, for example
ALL_COMPUNITS (objfile, s)
with an equivalent like this
for (compunit_symtab *s : all_compunits (current_program_space))
in order to avoid nested loops like
for (objfile *objfile : all_objfiles (current_program_space))
for (compunit_symtab *s : objfile_compunits (objfile))
{
...
...
}
In most cases, the objfile variable is not needed for anything else than
iterating on the compunit_symtabs. For cases where the outer iteration
variable is needed, then we can use the nested loops.
I am not sure which one I like best. The flat version reduces indentation, but
the nested version makes it clear and explicit how the data is represented, so
it might help readers who are less familiar with the code.
Also, in theory, according to the coding style, we should write
for (...)
{
for (...)
{
...
...
}
}

That case is fine, but the problem is a case like:
for (objfile *objfile : ...)
for (objfile *objfile2 : ...)
Here the compiler complains about the inner for, because 'objfile' is a
variable.
Another case was one where 'symtab' was the name of a function

Same for me. Maybe I lean a bit toward the explicit form but that might
only be because I already have the patch in hand.

I thought it was ok to leave a single statement unbraced, though I
personally never do this for something like:
for (...)
if ...
else...
...since I think that's less readable than the braced version.
If the braces are needed then that probably argues for a smarter
iterator, to avoid excessive indentation.

They are needed if we want to strictly follow the GNU coding style:
https://www.gnu.org/prep/standards/standards.html#Clean-Use-of-C-Constructs
I think what you did is easy to read, since it's pretty straightforward.
We could always make an exception for these constructs, but it would
probably end up being confusing to understand and explain when you can
omit the braces and when you can't.
If we end up using "smarter iterators" (for the lack of a better name)
they could be overloads:
/* Iterate on all compunits of an objfile. */
... all_compunits (objfile *);
/ Iterate on all compunits of a program space. */
... all_compunits (program_space *);
And let's say that all_compunits (program_space *) returns tuples of
<objfile *, compunit_symtab *>, we'll be able to use structured bindings
when we switch to C++17 :). Something like:
for (const auto &[objfile, compunit] : all_compunits (pspace))

I gave this a brief try. I wrote a "nested" iterator to make this
generic and then converted all_compunits.
With the nested iterator, one needs to write:
for (auto blah : all_compunits ())
{
compunit_symtab *s = blah.second;
This looked ugly to me.
Alternatively, we'd have to write a "second-selecting" wrapper iterator.
I didn't implement it but I suppose it would look like:
for (compunit_symtab *s : second_adapter<all_compunits> ())
...
This seemed a bit obscure to me, though.
In the end I think I prefer the explicit route. It does need more
indentation (I will add the missing braces), but the explicitness seems
good. To me, there doesn't seem to be a strong reason to prefer the
shorter formulations; and the new iterators and adapters that would be
needed are just a bunch more code to try to track through.
Let me know what you think about this. If you like the second_adapter
approach, I can implement that.

In that case it would always return a specialized struct
struct {
objfile *objfile;
compunit_symtab *compunit;
};

Yeah, I think the second_adapter approach just makes things more
obscure.
Really, I am fine with what you did.

Ok. I added the missing braces and re-tested it on the buildbot
("Fedora-x86_64-m64"); and I am going to push it now.

If it's a natural fit, then I think it'd be nice. Is there a downside?

Yeah. Though, I think that if we took this route, then
all_compunits ()
could still return just a compunit pointer, not two things:
compunit_symtab *all_compunits ()
because you can always get the objfile pointer from compunit_symtab::objfile.

Me, I don't.

in the threads/inferiors iterators I named the range types xxx_range
and then added methods to return the range instead of calling
the ctor directly. In this case, it'd be the equivalent of naming
the class above
class objfile_compunits_range : public next_adapter<struct compunit_symtab>
{
and then adding a method to objfile::compunits() method like:
objfile_compunits_range compunits ()
{ return objfile_compunits_range (this); }
Then the client code would look like:
> - ALL_OBJFILE_COMPUNITS (objfile, cust)
> + for (struct compunit_symtab *cust : objfile->compunits ())
Instead of:
> - ALL_OBJFILE_COMPUNITS (objfile, cust)
> + for (struct compunit_symtab *cust : objfile_compunits (objfile))
At the time, I thought that read better on the client side. I.e.,
we have:
inf->threads ()
instead of:
inf_threads (inf)
OOC, did you consider following that, and decided again?
No need to redo the series or anything, I'm just curious,
since I would have taken a different choice.

In the long run I still hope to get rid of compunit_symtab::objfile.
Though I suppose this could just be added to the future to-do list.

I didn't even think of it. I will add this to my to-do list, it does
look better.
Also maybe I next_adapter should be renamed to something better, at
least having the word "range" in it?
