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.

PR exp/28359 points out that 'ptype/o' does not work when the current
language is "asm".
I tracked this down to a hard-coded list of languages in typeprint.c.
This patch replaces this list with a method on 'language_defn'
instead. If all languages are ever updated to have this feature, the
method could be removed; but in the meantime this lets each language
control what happens.
I looked at having each print_type method simply modify the flags
itself, but this doesn't work very well with the feature that disables
method-printing by default (but allows it via a flag).

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.

This changes GDB to use frame_info_ptr instead of frame_info *
The substitution was done with multiple sequential `sed` commands:
sed 's/^struct frame_info;/class frame_info_ptr;/'
sed 's/struct frame_info \*/frame_info_ptr /g' - which left some
issues in a few files, that were manually fixed.
sed 's/\<frame_info \*/frame_info_ptr /g'
sed 's/frame_info_ptr $/frame_info_ptr/g' - used to remove whitespace
problems.
The changed files were then manually checked and some 'sed' changes
undone, some constructors and some gets were added, according to what
made sense, and what Tromey originally did

Make an introduction of a new print setting that can be set by 'set
print nibbles [on|off]'. The default value if OFF, which can be changed
by user manually. Of course, 'show print nibbles' is also included in
the patch.
The new feature displays binary values by group, with four bits per
group. The motivation for this work is to enhance the readability of
binary values.
Here's a GDB session before this patch is applied.
(gdb) print var_a
$1 = 1230
(gdb) print/t var_a
$2 = 10011001110
With this patch applied, we can use the new print setting to display the
new form of the binary values.
(gdb) print var_a
$1 = 1230
(gdb) print/t var_a
$2 = 10011001110
(gdb) set print nibbles on
(gdb) print/t var_a
$3 = 0100 1100 1110

The next patch will want to do language->print_type(type, ...), to
print a type in a given language, avoiding a dependency on the current
language. That doesn't work correctly currently, however, because
most language implementations of language_defn::print_type call
c_print_type without passing down the language. There are two
overloads of c_print_type, one that takes a language, and one that
does not. The one that does not uses the current language, defeating
the point of calling language->print_type()...
This commit removes the c_print_type overload that does not take a
language, and adjusts the codebase throughout to always pass down a
language. In most places, there's already an enum language handy.
language_defn::print_type implementations naturally pass down
this->la_language. In a couple spots, like in ada-typeprint.c and
rust-lang.c there's no enum language handy, but the code is written
for a specific language, so we just hardcode the language.
In gnuv3_print_method_ptr, I wasn't sure whether we could hardcode C++
here, and we don't have an enum language handy, so I made it use the
current language, just like today. Can always be improved later.

target_read_string takes a byte order parameter, but only uses this to
check whether a given character is zero. This is readily done without
requiring the parameter, so remove it.

The Rust compiler plans to change the encoding of a Rust 'char' type
to use DW_ATE_UTF. You can see the discussion here:
https://github.com/rust-lang/rust/pull/89887
However, this fails in gdb. I looked into this, and it turns out that
the handling of DW_ATE_UTF is currently fairly specific to C++. In
particular, the code here assumes the C++ type names, and it creates
an integer type.
This comes from commit 53e710acd ("GDB thinks char16_t and char32_t
are signed in C++"). The message says:
Both places need fixing. But since I couldn't tell why dwarf2read.c
needs to create a new type, I've made it use the per-arch built-in
types instead, so that the types are only created once per arch
instead of once per objfile. That seems to work fine.
... which is fine, but it seems to me that it's also correct to make a
new character type; and this approach is better because it preserves
the type name as well. This does use more memory, but first we
shouldn't be too concerned about the memory use of types coming from
debuginfo; and second, if we are, we should implement type interning
anyway.
Changing this code to use a character type revealed a couple of
oddities in the C/C++ handling of TYPE_CODE_CHAR. This patch fixes
these as well.
I filed PR rust/28637 for this issue, so that this patch can be
backported to the gdb 11 branch.

The bug fixed by this [1] patch was caused by an out-of-bounds access to
a value's content. The code gets the value's content (just a pointer)
and then indexes it with a non-sensical index.
This made me think of changing functions that return value contents to
return array_views instead of a plain pointer. This has the advantage
that when GDB is built with _GLIBCXX_DEBUG, accesses to the array_view
are checked, making bugs more apparent / easier to find.
This patch changes the return types of these functions, and updates
callers to call .data() on the result, meaning it's not changing
anything in practice. Additional work will be needed (which can be done
little by little) to make callers propagate the use of array_view and
reap the benefits.

I noticed that some methods in language_defn could use
unique_xmalloc_ptr<char> rather than a plain 'char *'. This patch
implements this change, fixing up the fallout and changing
gdb_demangle to also return this type. In one spot, std::string is
used to simplify some related code, and in another, an auto_obstack is
used to avoid manual management.

This removes union exp_element functions that either create such
elements or walk them. struct expression no longer holds
exp_elements. A couple of language_defn methods are also removed, as
they are obsolete.
Note that this patch also removes the print_expression code. The only
in-tree caller of this was from dump_prefix_expression, which is only
called when expression debugging is enabled. Implementing this would
involve a fair amount of code, and it seems to me that prefix dumping
is preferable anyway, as it is unambiguous. So, I have not
reimplemented this feature.

enum exp_opcode is created from all the .def files, but then each
language is required to implement its own op_name function to turn an
enum value to a string. This seemed over-complicated to me, and this
patch removes the per-language functions in favor of simply using the
.def names for all languages. Note that op_name is only used for
dumping expressions, which is a maintainer/debug feature.
Furthermore, I don't think there was any case where the .def name and

Consider the following GDB session:
$ gdb
(gdb) set language c
(gdb) ptype void
type = void
(gdb) set language fortran
(gdb) ptype void
No symbol table is loaded. Use the "file" command.
(gdb)
With no symbol file loaded GDB and the language set to C GDB knows
about the type void, while when the language is set to Fortran GDB
doesn't know about the void, why is that?
In f-lang.c, f_language::language_arch_info, we do have this line:
lai->primitive_type_vector [f_primitive_type_void]
= builtin->builtin_void;
where we add the void type to the list of primitive types that GDB
should always know about, so what's going wrong?
It turns out that the primitive types are stored in a C style array,
indexed by an enum, so Fortran uses `enum f_primitive_types'. The
array is allocated and populated in each languages language_arch_info
member function. The array is allocated with an extra entry at the
end which is left as a NULL value, and this indicates the end of the
array of types.
Unfortunately for Fortran, a type is not assigned for each element in
the enum. As a result the final populated array has gaps in it, gaps
which are initialised to NULL, and so every time we iterate over the
list (for Fortran) we stop early, and never reach the void type.
This has been the case since 2007 when this functionality was added to
GDB in commit cad351d11d6c3f6487cd.
Obviously I could just fix Fortran by ensuring that either the enum is
trimmed, or we create types for the missing types. However, I think a
better approach would be to move to C++ data structures and removed
the fixed enum indexing into the array approach.
After this commit the primitive types are pushed into a vector, and
GDB just iterates over the vector in the obvious way when it needs to
hunt for a type. After this commit all the currently defined
primitive types can be found when the language is set to Fortran, for
example:
$ gdb
(gdb) set language fortran
(gdb) ptype void
type = void
(gdb)
A new test checks this functionality.
I didn't see any other languages with similar issues, but I could have
missed something.

GDB already has a global symbol `demangle` (a boolean), having a
language method called `demangle` is not a good idea as we often want
to reference `demangle` the control variable inside `demangle` the
member function.
This commit renames `demangle` the member function to
`demangle_symbol`.

Convert language_data::la_case_sensitivity member variable to a virtual
method language_defn::case_sensitivity.
This is mostly straight forward. The only slight problem is that I
ended up deleting this comment from ada-lang.c:
/* Yes, Ada is case-insensitive, but that's not quite what this
means. */
However, as the comment (which has existed since Ada support was first
added to GDB) doesn't explain _why_ Ada sets case sensitivity to on
despite being a generally case insensitive language, this doesn't
really help me much.
If I understood _why_ the setting doesn't quite mean what it seems to
mean (at least as far as Ada is concerned) then I would extend the
comment on language_defn::case_sensitivity (in language.h) to include
the detail, and note how this impacts Ada. But as it stands I've just
deleted the comment for now.

Convert language_data::la_range_check member variable to a virtual
method language_defn::range_checking_on_by_default.
Where the previous member variable was of type 'enum range_check', the
new member function returns a boolean that selects between range
checking being on or off. This removes the possibility of a language
having its default be the third enum state, range_check_warn, which
no language currently used.
This all makes sense I think, the language's true/false provides the
default when the global 'set check range' is set to 'auto'.

Convert language_data::string_lower_bound member variable to a virtual
method language_defn::string_lower_bound.
Over all of the languages we currently support there are currently
only two values for the lower bound, 0 or 1. I noticed that in all
cases, if a language has C style arrays then the lower bound is 0,
otherwise the lower bound is 1. So the default for the virtual method
in language.h makes use of this, which means languages don't have to
worry about providing a string_lower_bound method at all.
Except for Modula2. This language is defined to not have C style
arrays, but has a string_lower_bound index of 0, this behaviour is
maintained after this commit by having Modula2 be the only language
that overrides the string_lower_bound method.

Move the language_data::la_language member variable into the
langage_defn class.
I have not made the la_language member variable a method of
langage_defn simply because of the large number of places that
la_language is referenced throughout GDB. I have made the new member
variable constant though, so this should prevent accidental
assignment.
In the future we might consider converting la_language to a method,
but right now my goal is to remove the langage_data class, so I'm
happy to leave la_language as a constant member variable.

virtual method language_defn::filename_extensions.
The new method returns a vector of filename extensions, which means
that where previously we needed a NULL marker on the end of the list,
we can now discard this.
All of the old arrays that contained the extensions now become static
data within each languages filename_extensions method.
I've updated the single use of the filename_extensions method to make
use of this method returning a vector. And, just in case anyone
accidentally adds a NULL marked into a languages extensions list, I've
added a new assert in add_filename_language (symtab.c) to catch this.

Convert the two language_data member variables la_name and
la_natural_name to virtual methods in language_defn struct called name
and natural_name respectively.
The virtual methods in the language_defn base class are pure virtual,
as every language must implement these, and as every language has a
unique name there's no sensible default here.
Given that every language must implement these methods I did wonder
about making this data passed into the base class constructor, but in
the end I went with the virtual method approach. I'm open to changing
this approach if people prefer the constructor approach.
During updating the calls to language_defn::name I found in
add_set_language_command a place where we took la_name and then
capitalised the first letter to create a language name that could be
used in the documentation string. I replaced this with a use of
natural_name instead as this seemed a better choice, in most cases
this will make no difference, as for most languages the natural_name
is just the name with the first character in upper case, but for some
languages, for example 'Open-CL' and 'Objective-C' this is not the
case.
In the case of asm_language the name is 'asm', while the natural_name
was previously 'assembly'. I changed the natural name to 'Assembly',
this makes the documentation string case above cleaner, however, this
will change the MI output for -var-info-expression, where the 'lang'
field will change from 'assembly' to 'Assembly'. It is possible this
could be a breaking change if a front-end is relying on the existing
name.
