b8a6e98781 Set section indices when symbols are made
Most places in gdb that create a new symbol will apply a section
offset to the address.  It seems to me that the choice of offset here
is also an implicit choice of the section.  This is particularly true
if you examine fixup_section, which notes that it must be called
before such offsets are applied -- meaning that if any such call has
an effect, it's purely by accident.

This patch cleans up this area by tracking the section index and
applying it to a symbol when the address is set.  This is done for
nearly every case -- the remaining cases will be handled in later
patches.

55fc1623f9 Add name canonicalization for C
PR symtab/29105 shows a number of situations where symbol lookup can
result in the expansion of too many CUs.

What happens is that lookup_signed_typename will try to look up a type
like "signed int".  In cooked_index_functions::expand_symtabs_matching,
when looping over languages, the C++ case will canonicalize this type
name to be "int" instead.  Then this method will proceed to expand
every CU that has an entry for "int" -- i.e., nearly all of them.  A
crucial component of this is that the caller, objfile::lookup_symbol,
does not do this canonicalization, so when it tries to find the symbol
for "signed int", it fails -- causing the loop to continue.

This patch fixes the problem by introducing name canonicalization for
C.  The idea here is that, by making C and C++ agree on the canonical
name when a symbol name can have multiple spellings, we avoid the bad
behavior in objfile::lookup_symbol (and any other such code -- I don't
know if there is any).

Unlike C++, C only has a few situations where canonicalization is
needed.  And, in particular, due to the lack of overloading (thus
avoiding any issues in linespec) and due to the way c-exp.y works, I
think that no canonicalization is needed during symbol lookup -- only
during symtab construction.  This explains why lookup_name_info is not
touched.

The stabs reader is modified on a "best effort" basis.

The DWARF reader needed one small tweak in dwarf2_name to avoid a
regression in dw2-unusual-field-names.exp.  I think this is adequately
explained by the comment, but basically this is a scenario that should
not occur in real code, only the gdb test suite.

lookup_signed_typename is simplified.  It used to search for two
different type names, but now gdb can search just for the canonical
form.

gdb.dwarf2/enum-type.exp needed a small tweak, because the
canonicalizer turns "unsigned integer" into "unsigned int integer".
It seems better here to use the correct C type name.

Add the `length` and `set_length` methods on `struct type`, in order to remove
the `TYPE_LENGTH` macro.  In this patch, the macro is changed to use the
getter, so all the call sites of the macro that are used as a setter are
changed to use the setter method directly.  The next patch will remove the

08b8a139c9 Rewrite registry.h
This rewrites registry.h, removing all the macros and replacing it
with relatively ordinary template classes.  The result is less code
than the previous setup.  It replaces large macros with a relatively
straightforward C++ class, and now manages its own cleanup.

The existing type-safe "key" class is replaced with the equivalent
template class.  This approach ended up requiring relatively few
changes to the users of the registry code in gdb -- code using the key
system just required a small change to the key's declaration.

All existing users of the old C-like API are now converted to use the
type-safe API.  This mostly involved changing explicit deletion
functions to be an operator() in a deleter class.

The old "save/free" two-phase process is removed, and replaced with a
single "free" phase.  No existing code used both phases.

The old "free" callbacks took a parameter for the enclosing container
object.  However, this wasn't truly needed and is removed here as
well.

59dfe8ad84 gdb: rename start_symtab/end_symtab to start_compunit_symtab/end_compunit_symtab
It's a bit confusing because we have both "compunit_symtab" and "symtab"
types, and many methods and functions containing "start_symtab" or
"end_symtab", which actually deal with compunit_symtabs.  I believe this
comes from the time before compunit_symtab was introduced, where
symtab did the job of both.

Rename everything I found containing start_symtab or end_symtab to use
start_compunit_symtab or end_compunit_symtab.

cd3f655cc7 gdb: add accessors for field (and call site) location
Add accessors for the various location values in struct field.  This
lets us assert that when we get a location value of a certain kind (say,
bitpos), the field's location indeed contains a value of that kind.

Remove the SET_FIELD_* macros, instead use the new setters directly.
Update the FIELD_* macros used to access field locations to go through
the getters.  They will be removed in a subsequent patch.

There are places where the FIELD_* macros are used on call_site_target
structures, because it contains members of the same name (loc_kind and
loc).  For now, I have replicated the getters/setters in
call_site_target.  But we could perhaps eventually factor them in a
"location" structure that can be used at both places.

Note that the field structure, being zero-initialized, defaults to a
bitpos location with value 0.  While writing this patch, I tried to make
it default to an "unset" location, to catch places where we would miss
setting a field's location.  However, I found that some places relied on
the default being "bitpos 0", so I left it as-is.  This change could
always be done as follow-up work, making these places explicitly set the
"bitpos 0" location.

I found two issues to fix:

 - I got some failures in the gdb.base/infcall-nested-structs-c++.exp
   test.  They were caused by two functions in amd64-tdep.c using
   TYPE_FIELD_BITPOS before checking if the location is of the bitpos
   kind, which they do indirectly through `field_is_static`.  Simply
   move getting the bitpos below the field_is_static call.

 - I got a failure in gdb.xml/tdesc-regs.exp.  It turns out that in
   make_gdb_type_enum, we set enum field values using SET_FIELD_BITPOS,
   and later access them through FIELD_ENUMVAL.  Fix that by using
   set_loc_enumval to set the value.

d3fd12dfc5 gdb: add field::name / field::set_name
Add the `name` and `set_name` methods on `struct field`, in order to
remove `FIELD_NAME` and `TYPE_FIELD_NAME` macros.  In this patch, the
macros are changed to use `field::name`, so all the call sites that are
used to set the field's name are changed to use `field::set_name`.
The next patch will remove the macros completely.

Note that because of the name clash between the existing field named
`name` and the new method, I renamed the field `m_name`.  It is not
private per-se, because we can't make `struct field` a non-POD yet, but
it should be considered private anyway (not accessed outside `struct
field`).

a52d653e91 gdb: delete SYMBOL_SECTION and MSYMBOL_SECTION macros
Delete two more symbol/section related macros.  This time it's
SYMBOL_SECTION and MSYMBOL_SECTION.

As with general_symbol_info::m_name it is not currently possible to
make general_symbol_info::m_section private as general_symbol_info
must remain a POD type.

But other than failing to make the new m_section private, this change
does what you'd expect, adds a get and set member function and updates
all users to use the new functions instead of the previous wrapper
macros.

There should be no user visible change after this commit.

dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c).  I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it?  What if the lines around it are also
wrong, do I fix them too?  I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.

So I propose to fix as much as possible once and for all (hopefully).

One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines.  My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for.  So you
already need a somewhat efficient way to do this.

Using some interactive tool, rather than plain git-blame, makes this
trivial.  For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too.  My point is that it won't
really make archeology more difficult.

The other typical counter argument is that it will cause conflicts with
existing patches.  That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve.  I have also tried "git
rebase --ignore-whitespace", it seems to work well.  Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

314ad88df6 Use type_instance_flags more throughout
A later patch in this series will rewrite enum_flags fixing some API
holes.  That would cause build failures around code using
type_instance_flags.  Or rather, that should be using it, but wasn't.

This patch fixes it by using type_instance_flags throughout instead of
plain integers.

Note that we can't make the seemingly obvious change to struct
type::instance_flags:

 -  unsigned instance_flags : 9;
 +  ENUM_BITFIELD (type_instance_flag_value) instance_flags : 9;

Because G++ complains then that 9 bits isn't sufficient for holding
all values of type_instance_flag_value.

So the patch adds an type::instance_flags() method, which takes care
of casting appropriately, and adds a separate type::set_instance_flags
method, following the pattern of the ongoing TYPE_XXX macro
elimination.  This converts uses of TYPE_INSTANCE_FLAGS to
type::instance_flags() in the places where the code was already being
touched, but there are still many references to the
TYPE_INSTANCE_FLAGS macro left behind.  Those could/should be fully
replaced at some point.

use the new method.  The next patch will remove the macro completely.

gdb/ChangeLog:

	* gdbtypes.h (struct type) <is_unsigned, set_is_unsigned>: New
	methods.
	(TYPE_UNSIGNED): Use type::is_unsigned.  Change all write call
	sites to use type::set_is_unsigned.

bb6e55f3ee Remove obsolete gdbarch_static_transform_name
gdbarch_static_transform_name is completely Solaris-specific or rather
specific to the Studio compilers.  Studio cc has deprecated Stabs support
in the 12.4 release back in 2015, GCC has defaulted to DWARF-2 on Solaris
7+ since 2004 and Stabs themselves are pretty much obsolete, so the whole
code can go.

Tested on sparcv9-sun-solaris2.11 and x86_64-pc-linux-gnu with
--enable-targets=all.

	* sol2-tdep.c (sol2_static_transform_name): Remove.
	(sol2_init_abi): Don't register it.
	* gdbarch.sh (static_transform_name): Remove.
	* gdbarch.c, gdbarch.h: Regenerate.

	* dbxread.c (read_dbx_symtab) <'S'>: Remove call to
	gdbarch_static_transform_name.
	* mdebugread.c (parse_partial_symbols) <'S'>: Likewise.
	* stabsread.c (define_symbol) <'X'>: Remove.
	(define_symbol) <'S'>: Remove gdbarch_static_transform_name
	handling.
	<'V'>: Likewise.
	* xcoffread.c (scan_xcoff_symtab): Remove gdbarch.
	<'S'>: Remove call to gdbarch_static_transform_name.

b6cdac4b80 gdb: remove FIELD_TYPE macro
Remove the `FIELD_TYPE` macro, changing all the call sites to use
`field::type` directly.

gdb/ChangeLog:

	* gdbtypes.h (FIELD_TYPE): Remove.  Change all call sites
	to use field::type instead.

5d14b6e5d6 gdb: add field::type / field::set_type
Add the `type` and `set_type` methods on `struct field`, in order to
remoremove the `FIELD_TYPE` macro.  In this patch, the `FIELD_TYPE`
macro is changed to use `field::type`, so all the call sites that are
useused to set the field's type are changed to use `field::set_type`.
The next patch will remove `FIELD_TYPE` completely.

Note that because of the name clash between the existing field named
`type` and the new method, I renamed the field `m_type`.  It is not
private per-se, because we can't make `struct field` a non-POD yet, but
it should be considered private anyway (not accessed outside `struct
field`).

gdb/ChangeLog:

	* gdbtypes.h (struct field) <type, set_type>: New methods.
	Rename `type` field to...
	<m_type>: ... this.  Change references throughout to use type or
	set_type methods.
	(FIELD_TYPE): Use field::type.  Change call sites that modify
	the field's type to use field::set_type instead.

ceacbf6edf gdb: remove TYPE_FIELD macro
Replace all uses of it by type::field.

Note that since type::field returns a reference to the field, some spots
are used to assign the whole field structure.  See ctfread.c, function
attach_fields_to_type, for example.  This is the same as was happening
with the macro, so I don't think it's a problem, but if anybody sees a
really nicer way to do this, now could be a good time to implement it.

gdb/ChangeLog:

	* gdbtypes.h (TYPE_FIELD): Remove.  Replace all uses with
	type::field.

80fc5e77f0 gdb: remove TYPE_FIELDS macro
Remove all uses of the `TYPE_FIELDS` macro.  Replace them with either:

1) type::fields, to obtain a pointer to the fields array (same as
   TYPE_FIELDS yields)
2) type::field, a new convenience method that obtains a reference to one
   of the type's field by index.  It is meant to replace

     TYPE_FIELDS (type)[idx]

   with

     type->field (idx)

gdb/ChangeLog:

	* gdbtypes.h (struct type) <field>: New method.
	(TYPE_FIELDS): Remove, replace all uses with either type::fields
	or type::field.

is changed to the `type::fields`, so all the call sites that use it to

1f704f761b gdb: remove TYPE_NFIELDS macro
Remove `TYPE_NFIELDS`, changing all the call sites to use
`type::num_fields` directly.  This is quite a big diff, but this was
mostly done using sed and coccinelle.  A few call sites were done by
hand.

5e33d5f4e1 gdb: add type::num_fields / type::set_num_fields
Add the `num_fields` and `set_num_fields` methods on `struct type`, in
order to remove the `TYPE_NFIELDS` macro.  In this patch, the
`TYPE_NFIELDS` macro is changed to use `type::num_fields`, so all the
call sites that are used to set the number of fields are changed to use
`type::set_num_fields`.  The next patch will remove `TYPE_NFIELDS`
completely.

I think that in the future, we should consider making the interface of
`struct type` better.  For example, right now it's possible for the
number of fields property and the actual number of fields set to be out
of sync.  However, I want to keep the existing behavior in this patch,
just translate from macros to methods.

gdb/ChangeLog:

	* gdbtypes.h (struct type) <num_fields, set_num_fields>: New
	methods.
	(TYPE_NFIELDS): Use type::num_fields.  Change all call sites
	that modify the number of fields to use type::set_num_fields
	instead.
