6647f05df0 gdb: defer warnings when loading separate debug files
Currently, when GDB loads debug information from a separate debug
file, there are a couple of warnings that could be produced if things
go wrong.

In find_separate_debug_file_by_buildid (build-id.c) GDB can give a
warning if the separate debug file doesn't include any actual debug
information, and in separate_debug_file_exists (symfile.c) we can warn
if the CRC checksum in the separate debug file doesn't match the
checksum in the original executable.

The problem here is that, when looking up debug information, GDB will
try several different approaches, lookup by build-id, lookup by
debug-link, and then a lookup from debuginfod.  GDB can potentially
give a warning from an earlier attempt, and then succeed with a later
attempt.  In the cases I have run into this is primarily a warning
about some out of date debug information on my machine, but then GDB
finds the correct information using debuginfod.  This can be confusing
to a user, they will see warnings from GDB when really everything is
working just fine.

For example:

  warning: the debug information found in "/usr/lib/debug//lib64/ld-2.32.so.debug" \
      does not match "/lib64/ld-linux-x86-64.so.2" (CRC mismatch).

This diagnostic was printed on Fedora 33 even when the correct
debuginfo was downloaded.

In this patch I propose that we defer any warnings related to looking
up debug information from a separate debug file.  If any of the
approaches are successful then GDB will not print any of the warnings.
As far as the user is concerned, everything "just worked".  Only if
GDB completely fails to find any suitable debug information will the
warnings be printed.

The crc_mismatch test compiles two executables: crc_mismatch and
crc_mismatch-2 and then strips them of debuginfo creating separate
debug files. The test then replaces crc_mismatch-2.debug with
crc_mismatch.debug to trigger "CRC mismatch" warning. A local
debuginfod server is setup to supply the correct debug file, now when
GDB looks up the debug info no warning is given.

The build-id-no-debug-warning.exp is similar to the previous test. It
triggers the "separate debug info file has no debug info" warning by
replacing the build-id based .debug file with the stripped binary and
then loading it to GDB.  It then also sets up local debuginfod server
with the correct debug file to download to make sure no warnings are
emitted.

f34652de0b internal_error: remove need to pass __FILE__/__LINE__
Currently, every internal_error call must be passed __FILE__/__LINE__
explicitly, like:

  internal_error (__FILE__, __LINE__, "foo %d", var);

The need to pass in explicit __FILE__/__LINE__ is there probably
because the function predates widespread and portable variadic macros
availability.  We can use variadic macros nowadays, and in fact, we
already use them in several places, including the related
gdb_assert_not_reached.

So this patch renames the internal_error function to something else,
and then reimplements internal_error as a variadic macro that expands
__FILE__/__LINE__ itself.

The result is that we now should call internal_error like so:

  internal_error ("foo %d", var);

Likewise for internal_warning.

The patch adjusts all calls sites.  99% of the adjustments were done
with a perl/sed script.

The non-mechanical changes are in gdbsupport/errors.h,
gdbsupport/gdb_assert.h, and gdb/gdbarch.py.

98badbfdc2 Use gdb_bfd_ref_ptr in objfile
This changes struct objfile to use a gdb_bfd_ref_ptr.  In addition to
removing some manual memory management, this fixes a use-after-free
that was introduced by the registry rewrite series.  The issue there
was that, in some cases, registry shutdown could refer to memory that
had already been freed.  This help fix the bug by delaying the
destruction of the BFD reference (and thus the per-bfd object) until
after the registry has been shut down.

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.

28c5801a94 Do not double-read minimal symbols for PE COFF
This changes coffread.c to avoid re-reading minimal symbols when
possible.  This only works when there are no COFF symbols to be read,
but at least for my mingw builds of gdb, this seems to be the case.

Tested using the AdaCore internal test suite on Windows.  I also did
some local builds to ensure that no warnings crept in.

31de881f8f Always use dwarf2_initialize_objfile
Internally we noticed that some tests would fail like so on Windows:

warning: Section .debug_aranges in [...] has duplicate debug_info_offset 0x0, ignoring .debug_aranges.

Debugging showed that, in fact, a second CU was being created at this
offset.  We tracked this down to the fact that, while the ELF reader
is careful to re-use the per-BFD data, other readers are not, and
could re-read the DWARF data multiple times.

However, since the change to allow an objfile to have multiple "quick
symbol" implementations, there's no reason for this approach -- it's
safe and easy for all symbol readers to reuse the per-BFD data when
reading DWARF.

This patch implements this idea, simplifying dwarf2_build_psymtabs and
making it private, and then switching to dwarf2_initialize_objfile as
the sole way to start the DWARF reader.

Note that, while I think the call to dwarf2_build_frame_info in
machoread.c is also obsolete, I haven't attempted to remove it here.

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.

Make compunit_filetabs, used to iterate a compunit_symtab's filetabs, a
method of compunit_symtab.  The name filetabs conflicts with the current

nothing outside of compunit_symtab uses it, so we should treat it as
private (even though it's not actually private).  Rename the
last_filetab field to m_last_filetab as well (it's only used on
compunit_symtab::add_filetab).

Adjust the COMPUNIT_FILETABS macro to keep its current behavior of
returning the first filetab.

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.

	* coff-pe-read.c (add_pe_forwarded_sym): Make use of section_index
	and set_section_index member functions where appropriate.

d5d24e12f9 Fix build errors for armhf
When building for 32-bit ARM, I ran into a couple build failures.

The first one seems to be caused by recent changes to warning switches,
leading to the following error:

--
In file included from gdb/coffread.c:35:0:
gdb/coffread.c: In function  "void enter_linenos(file_ptr, int, int, objfile*)":
gdb/complaints.h:40:40: error: format "%ld" expects argument of type "long int", but argument 2 has type "file_ptr {aka long long int}" [-Werror=format=]

       complaint (_("Line number pointer %ld lower than start of line numbers"),
       ^~~~~~~~~
--

The other one is due to a narrowing conversion in valops.c:

--
gdb/valops.c: In function "value* value_assign(value*, value*)":
gdb/gdbtypes.h:1798:43: error: narrowing conversion of "type->type::length" from "ULONGEST {aka long long unsigned int}" to "size_t {aka unsigned int}" inside { } [-Werror=narrowing]

a9e48095a8 gdb: define COFF file offsets with file_ptr
The arguments to these functions are file_ptr, so these declarations
were accidentally implicitly down-casting them to signed int. This
allows for reading files between 2 and 4 GB in size in my testing (I
don't have a larger dll currently to test). These may not be natively
supported by Windows, but can appear when using split-dwarf information.

This solves a "can't get string table" error resulting from attempting
to pass a negative offset to bfd_seek. I encountered this occuring while
trying to use a debug file for libLLVM.dll, but searching online reveals
at least one other person may have run into a similar problem with
Firefox?

With this patch, the debug file appears to load successfully and I can
see debug information in gdb for the library.

	* coffread.c (linetab_offset): Change type to file_ptr.
	(linetab_size): Likewise.
	(enter_linenos): Change parameter type to file_ptr.

	(init_stringtab): Likewise.

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).

653223d356 gdb: add type::is_unsigned / type::set_is_unsigned
Add the `is_unsigned` and `set_is_unsigned` methods on `struct type`, in
order to remove the `TYPE_UNSIGNED` macro.  In this patch, the
`TYPE_UNSIGNED` macro is changed to use `type::is_unsigned`, so all the
call sites that are used to set this property on a type are changed to
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.

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.

3cabb6b069 gdb: add type::fields / type::set_fields
Add the `fields` and `set_fields` methods on `struct type`, in order to
remove the `TYPE_FIELDS` macro.  In this patch, the `TYPE_FIELDS` macro
is changed to the `type::fields`, so all the call sites that use it to
set the fields array are changed to use `type::set_fields`.  The next
patch will remove `TYPE_FIELDS` entirely.

gdb/ChangeLog:

	* gdbtypes.h (struct type) <fields, set_fields>: New methods.
	(TYPE_FIELDS): Use type::fields.  Change all call sites that
	modify the propery to use type::set_fields instead.

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.

84d53fa9d2 gdb: remove unnecessary NULL checks before xfree
I was inspired by a series of patches merged by Alan Modra in the other
projects, so I did the same in GDB with a bit of Coccinelle and grep.

This patch removes the unnecessary NULL checks before calls to xfree.
They are unnecessary because xfree already does a NULL check.  Since
free is supposed to handle NULL values correctly, the NULL check in
xfree itself is also questionable, but I've left it there for now.

	* coffread.c (patch_type): Remove NULL check before xfree.
