Pedro Alves b5ec771e60 Introduce lookup_name_info and generalize Ada's FULL/WILD name matching
Summary:
 - This is preparation for supporting wild name matching on C++ too.
 - This is also preparation for TAB-completion fixes.
 - Makes symbol name matching (think strcmp_iw) be based on a per-language method.
 - Merges completion and non-completion name comparison (think
   language_ops::la_get_symbol_name_cmp generalized).
 - Avoid re-hashing lookup name multiple times
 - Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling),
   both completion and non-completion.
 - Fixes Ada latent bug with verbatim name matches in expressions
 - Makes ada-lang.c use common|symtab.c completion code a bit more.

Ada's wild matching basically means that

 "(gdb) break foo"

will find all methods named "foo" in all packages.  Translating to
C++, it's roughly the same as saying that "break klass::method" sets
breakpoints on all "klass::method" methods of all classes, no matter
the namespace.  A following patch will teach GDB about fullname vs
wild matching for C++ too.  This patch is preparatory work to get
there.

Another idea here is to do symbol name matching based on the symbol
language's algorithm.  I.e., avoid dependency on current language set.

This allows for example doing

  (gdb) b foo::bar< int > (<tab>

and having gdb name match the C++ symbols correctly even if the
current language is C or Assembly (or Rust, or Ada, or ...), which can
easily happen if you step into an Assembly/C runtime library frame.

By encapsulating all the information related to a lookup name in a
class, we can also cache hash computation for a given language in the
lookup name object, to avoid recomputing it over and over.

Similarly, because we don't really know upfront which languages the
lookup name will be matched against, for each language we store the
lookup name transformed into a search name.  E.g., for C++, that means
demangling the name.  But for Ada, it means encoding the name.  This
actually forces us to centralize all the different lookup name
encoding in a central place, resulting in clearer code, IMO.  See
e.g., the new ada_lookup_name_info class.

The lookup name -> symbol search name computation is also done only
once per language.

The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are
generalized to work with both completion, and normal symbol look up.

At some point early on, I had separate completion vs non-completion
language vector entry points, but a single method ends up being better
IMO for simplifying things -- the more we merge the completion /
non-completion name lookup code paths, the less changes for bugs
causing completion vs normal lookup finding different symbols.

The ada-lex.l change is necessary because when doing

  (gdb) p <UpperCase>

then the name that is passed to write_ write_var_or_type ->
ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase",
and we end up doing a wild match against "UpperCase" lowercased by
ada_lookup_name_info's constructor.  I.e., "uppercase" wouldn't ever
match "UpperCase", and the symbol lookup fails.

This wouldn't cause any regression in the testsuite, but I added a new
test that would pass before the patch and fail after, if it weren't
for that fix.

This is latent bug that happens to go unnoticed because that
particular path was inconsistent with the rest of Ada symbol lookup by
not lowercasing the lookup name.

Ada's symbol_completion_add is deleted, replaced by using common
code's completion_list_add_name.  To make the latter work for Ada, we
needed to add a new output parameter, because Ada wants to return back
a custom completion candidates that are not the symbol name.

With this patch, minimal symbol demangled name hashing is made
consistent with regular symbol hashing.  I.e., it now goes via the
language vector's search_name_hash method too, as I had suggested in a
previous patch.

dw2_expand_symtabs_matching / .gdb_index symbol names were a
challenge.  The problem is that we have no way to telling what is the
language of each symbol name found in the index, until we expand the
corresponding full symbol, which is off course what we're trying to
avoid.  Language information is simply not considered in the index
format...  Since the symbol name hashing and comparison routines are
per-language, we now have a problem.  The patch sorts this out by
matching each name against all languages.  This is inneficient, and
indeed slows down completion several times.  E.g., with:

 $ cat script.cmd
 set pagination off
 set $count = 0
 while $count < 400
   complete b string_prin
   printf "count = %d\n", $count
   set $count = $count + 1
 end

 $ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd"

I get, before patch (-O2, x86-64):

 real    0m1.773s
 user    0m1.737s
 sys     0m0.040s

While after patch (-O2, x86-64):

 real    0m9.843s
 user    0m9.482s
 sys     0m0.034s

However, the following patch will optimize this, and will actually
make this use case faster compared to the "before patch" above:

 real    0m1.321s
 user    0m1.285s
 sys     0m0.039s

Pedro Alves 5ffa079369 Per-language symbol name hashing algorithm
Currently, we have a mess of symbol name hashing/comparison routines.
There's msymbol_hash for mangled names, and dict_hash and
msymbol_hash_iw for demangled names.  Then there's strcmp_iw,
strcmp_iw_ordered and Ada's full_match/wild_match, which all have to
agree with the hashing routines.  That's why dict_hash is really about
Ada names.  From the inconsistency department, minimal symbol hashing
doesn't go via dict_hash, so Ada's wild matching can't ever work with
minimal symbols.

This patch starts fixing this, by doing two things:

#1 - adds a language vector method to let each language decide how to
     compute a symbol name hash.

#2 - makes dictionaries know the language of the symbols they hold,
     and then use the dictionaries language to decide which hashing
     method to use.

For now, this is just scaffolding, since all languages install the
default method.  The series will make C++ install its own hashing
method later on, and will add per-language symbol name comparison
routines too.

This patch was originally based on a patch that Keith wrote for the
libcc1/C++ WIP support.

Paul N. Hilfinger c4d840bdd6 Extend hashed symbol dictionaries to work with Ada
This patch allows Ada to speed up symbol lookup by using the facilities
in dictionary.[ch] for hashed lookups.  First, we generalize dictionary
search to allow clients to specify any matching function compatible with
the hashing function. Next, we modify the hashing algorithm so that symbols
that wild-match a name hash to the same value.  Finally, we modify Ada
symbol lookup to use these facilities.

Because this patch touches on a hashing algorithm used by other
languages, I took the precaution of doing a speed test on a list of
about 12000 identifiers (repeatedly inserting all of them into a table
and then doing a lookup on a million names at random, thus testing the
speed of the hashing algorithm and how well it distributed names).
There was actually a slight speedup, probably as a result of open-
coding some of the tests in msymbol_hash_iw.  By design, the revised
hashing algorithm produces the same results as the original on most
"normal" C identifiers.

We considered augmenting the dictionary interface still further by allowing
different hashing algorithms for different dictionaries, based on the
(supposed) language of the symbols in that dictionary.  While this produced
better isolation of the changes to Ada programs, the additional flexibility
also complicated the dictionary interface.  I'd prefer to keep things
simple for now.

Tested w/o regressions on Linux i686.

ChangeLog:

	gdb/
	* ada-lang.c (ada_match_name): Use new API for wild_match.
	(wild_match): Change API to be consistent with that of strcmp_iw;
	return 0 for a match, and switch operand order.
	(full_match): New function.
	(ada_add_block_symbols): Use dict_iter_match_{first,next} for
	matching to allow use of hashing.
	* dictionary.c (struct dict_vector): Generalize iter_name_first,
	iter_name_next ot iter_match_first, iter_match_next.
	(iter_name_first_hashed): Replace with iter_match_first_hashed.
	(iter_name_next_hashed): Replace with iter_match_next_hashed.
	(iter_name_first_linear): Replace with iter_match_first_linear.
	(iter_name_next_linear): Replace with iter_match_next_linear.
	(dict_iter_name_first): Re-implement to use dict_iter_match_first.
	(dict_iter_name_next): Re-implement to use dict_iter_match_next.
	(dict_iter_match_first): New function.
	(dict_iter_match_next): New function.
	(dict_hash): New function.
	* dictionary.h (dict_iter_match_first, dict_iter_match_next): Declare.
	* psymtab.c (ada_lookup_partial_symbol): Use new wild_match API.
