on a structure with a C99 flexible array member being nested in
another structure.
"The GCC extension accepts a structure containing an ISO C99 "flexible array
member", or a union containing such a structure (possibly recursively)
to be a member of a structure.
There are two situations:
* A structure containing a C99 flexible array member, or a union
containing such a structure, is the last field of another structure,
for example:
struct flex { int length; char data[]; };
union union_flex { int others; struct flex f; };
struct out_flex_struct { int m; struct flex flex_data; };
struct out_flex_union { int n; union union_flex flex_data; };
In the above, both 'out_flex_struct.flex_data.data[]' and
'out_flex_union.flex_data.f.data[]' are considered as flexible
arrays too.
* A structure containing a C99 flexible array member, or a union
containing such a structure, is not the last field of another structure,
for example:
struct flex { int length; char data[]; };
struct mid_flex { int m; struct flex flex_data; int n; };
In the above, accessing a member of the array 'mid_flex.flex_data.data[]'
might have undefined behavior. Compilers do not handle such a case
consistently, Any code relying on this case should be modified to ensure
that flexible array members only end up at the ends of structures.
Please use the warning option '-Wflex-array-member-not-at-end' to
identify all such cases in the source code and modify them. This extension
is now deprecated.

GCC extension accepts the case when a struct with a flexible array member
is embedded into another struct or union (possibly recursively) as the last
field.

Size expressions were sometimes lost and not gimplified correctly,
leading to ICEs and incorrect evaluation order. Fix this by 1) not
recursing pointers when gimplifying parameters, which was incorrect

C2x makes it clear that thread-local declarations can never be
tentative definitions (the legacy feature of C where you can e.g. do
"int i;" more than once at file scope, possibly with one of the
declarations initialized, and it counts as exactly one definition),
but are always definitions in the absence of "extern". The wording
about external definitions was unclear in the thread-local case in C11
/ C17 (both about what counts as a tentative definition, and what is a
"definition" at all), not having been updated to cover the addition of
thread-local storage.
Implement this C2x requirement. Arguably this is a defect fix that
would be appropriate to apply for all standard versions, but for now
the change is conditional on flag_isoc2x (however, it doesn't handle
_Thread_local / thread_local any different from GNU __thread). Making
the change unconditional results in various TLS tests failing to
compile (gcc.dg/c11-thread-local-1.c gcc.dg/tls/thr-init-1.c
gcc.dg/tls/thr-init-2.c gcc.dg/torture/tls/thr-init-2.c
objc.dg/torture/tls/thr-init.m), though it's not clear if those tests
reflect any real code similarly trying to make use of thread-local
tentative definitions.

For C2x it was decided that _Atomic would be completely ignored on
function return types (just as was done for qualifiers in C11 DR#423),
to eliminate the potential for an rvalue returned by a function having
_Atomic-qualified type when an rvalue resulting from lvalue-to-rvalue
conversion could not have such a type. Implement this for GCC.

acc_on_device [PR107041]
The new -Wenum-int-mismatch warning triggers with -Wsystem-headers in
<openacc.h>, for obvious reasons the builtin acc_on_device uses int
type argument rather than enum which isn't defined yet when the builtin
is created, while the OpenACC spec requires it to have acc_device_t
enum argument. The header makes sure it has int underlying type by using
negative and __INT_MAX__ enumerators.
I've tried to make the builtin typegeneric or just varargs, but that
changes behavior e.g. when one calls it with some C++ class which has
cast operator to acc_device_t, so the following patch instead disables
the warning for this builtin.

While this isn't really a regression, the -fstrict-flex-arrays*
option is new in GCC 13 and so I think we should make -fsanitize=bounds
play with it well from the beginning.
The current behavior is that -fsanitize=bounds considers all trailing
arrays as flexible member-like arrays and both -fsanitize=bounds and
-fsanitize=bounds-strict because of a bug don't even instrument
[0] arrays at all, not as trailing nor when followed by other members.
I think -fstrict-flex-arrays* options can be considered as language
mode changing options, by default flexible member-like arrays are
handled like flexible arrays, but that option can change the set of
the arrays which are treated like that. So, -fsanitize=bounds should
change with that on what is considered acceptable and what isn't.
While -fsanitize=bounds-strict should reject them all always to
continue previous behavior.
The following patch implements that. To support [0] array instrumentation,
I had to change the meaning of the bounds argument to .UBSAN_BOUNDS,
previously it was the TYPE_MAX_VALUE of the domain unless ignore_off_by_one
(used for taking address of the array element rather than accessing it;
in that case 1 is added to the bound argument) and the later lowered checks
were if (index > bound) report_failure ().
The problem with that is that for [0] arrays where (at least for C++)
the max value is all ones, for accesses that condition will be never true;
for addresses of elements it was working (in C++) correctly before.
This patch changes it to add 1 + ignore_off_by_one, so -1 becomes 0 or
1 for &array_ref and changing the lowering to be if (index >= bound)
report_failure (). Furthermore, as C represents the [0] arrays with
NULL TYPE_MAX_VALUE, I treated those like the C++ ones.

This flag records whether a type is variably modified and is

A. add the following to clarify the relationship between -Warray-bounds
and the LEVEL of -fstrict-flex-array:
By default, the trailing array of a structure will be treated as a
flexible array member by '-Warray-bounds' or '-Warray-bounds=N' if
it is declared as either a flexible array member per C99 standard
onwards ('[]'), a GCC zero-length array extension ('[0]'), or an
one-element array ('[1]'). As a result, out of bounds subscripts
or offsets into zero-length arrays or one-element arrays are not
warned by default.
You can add the option '-fstrict-flex-arrays' or
'-fstrict-flex-arrays=LEVEL' to control how this option treat
trailing array of a structure as a flexible array member.
when LEVEL<=1, no change to the default behavior.
when LEVEL=2, additional warnings will be issued for out of bounds
subscripts or offsets into one-element arrays;
when LEVEL=3, in addition to LEVEL=2, additional warnings will be
issued for out of bounds subscripts or offsets into zero-length
arrays.
B. change -Warray-bounds=2 to exclude its control on how to treat
trailing arrays as flexible array members:
'-Warray-bounds=2'
This warning level also warns about the intermediate results
of pointer arithmetic that may yield out of bounds values.
This warning level may give a larger number of false positives
and is deactivated by default.

Implement C2x constexpr (a feature based on the C++ one but much more
minimal, with only constexpr variables, not functions).
I believe this implementation is fully functional for use of this
feature. However, there are several things that seem unclear about
the specification that I'll need to raise in NB comments. There are
also areas where there may be followup bug fixes because the
implementation doesn't reject some more obscure cases that ought to be
rejected: cases where a constexpr initializer for floating type meets
the constraints for a constant expression in initializers but not
those for an arithmetic constant expression (previously we haven't had
to track whether something is an arithmetic constant expression in
detail, unlike with integer constant expressions), and some cases
where a tag or struct or union member gets declared indirectly in the
declaration specifiers or declarator of a constexpr declaration, which
is not permitted (modulo lack of clarity in the specification) for
underspecified declarations in general (the cases of a declaration in
the initializer, or a tagged type being directly declared as a type
specifier, are already detected).
Cases of ambiguity in the specification include:
* Many questions (previously raised in WG14 discussions) over the rule
about what conversions do or do not involve a change of value that's
not allowed in a constexpr initializer, that aren't properly
addressed by the normative text (and where the footnote on the
subject isn't very clear either, and the examples don't necessarily
follow from the normative text). I've made a series of choices
there, that include disallowing all conversions between real and
complex types or between binary and decimal floating types in
constexpr initializers, that might not necessarily agree with how
things end up getting clarified.
The dfp.cc change also arises here, to allow quiet NaN initializers
of one DFP type to be used in a constexpr initializer for another
DFP type (as is possible for signaling NaNs) by ensuring the result
of such a conversion is properly marked as canonical (note that most
of the DFP code doesn't actually do anything with NaN payloads at
all).
* Various issues with what exactly counts as part of a declaration for
the purposes of the rule on underspecified declarations not
declaring any identifiers other than ordinary identifiers (and not
declaring more than one ordinary identifier, though the latter is
undefined behavior). These include cases where the declaration of a
struct / union / enum type appears inside typeof or alignas in the
declaration specifiers (the latter also applies with auto), or in
the declarator (e.g. an array size or in a parameter declaration).
The issues are similar to those involved in C90 DR#115 and C99 DRs
#277 and #341; the intent may not be the same in all the different
cases involved, but it's not clear that the normative wording in the
various places is sufficient to deduce the differences in intent.
* The wording about producing a compound literal constant using member
access is present in one place but another place only applies that
to named constants.
* It's not clear when a structure or union constant (a constexpr
variable or compound literal with structure or union type, or a
member with such type extracted by a series of member access
operations) can itself be used in an initializer (constexpr or
otherwise). Based on general wording for initializers not having
been changed, the working draft might only strictly allow it at
automatic storage duration (but elsewhere it would be undefined
behavior, not a constraint violation, so no diagnostic required) -
since that's the only case mentioned where a single expression of
structure or union type can be used to initialize an object of such
a type. But it definitely seems to be allowed in even constexpr
initializers at automatic storage duration - and since generally
constexpr initializers (any storage duration) are *more* constrained
than ordinary static storage duration initializers, it would seem
odd for it not to be allowed at static storage duration.
* When you do allow such initializers, it's then not entirely clear
how the constraint that constexpr pointer initializers must be null
pointer constants should be applied (given that a constexpr object
of pointer type is a null pointer but *not* a null pointer
constant). My guess would be that a constexpr struct or union
containing such a field should still be allowed as an initializer,
but the wording could be read otherwise.
* It also becomes important with constexpr exactly what kind of
constant expression an implicit zero initializer is; the wording for
default initialization only really deals with the value of the
initializer and not what kind of constant it is. In particular,
this affects whether {} is a valid constexpr initializer for a
pointer not of type void *, since the wording only talks about a
null pointer, not whether it's a null pointer *constant*. I assumed
that it should be a null pointer constant in that case.
* It's also not entirely clear whether constexpr can be used in the
declaration part of a for loop (which "shall only declare
identifiers for objects having storage class auto or register"). I
interpreted it as allowed (treating such objects as implicitly auto
just like those with no storage class specifiers), but it could also
be argued that constexpr is another storage class specifier and so
not allowed there.

Implement C2x auto, a more restricted version of the C++ feature
(closer to GNU C __auto_type in terms of what's supported).
Since the feature is very close to GNU C __auto_type, much of the
implementation can be shared. The main differences are:
* Any prior declaration of the identifier in an outer scope is
shadowed during the initializer (whereas __auto_type leaves any such
declaration visible until the initializer ends and the scope of the
__auto_type declaration itself starts). (A prior declaration in the
same scope is undefined behavior.)
* The standard feature supports braced initializers (containing a
single expression, optionally followed by a comma).
* The standard feature disallows the declaration from declaring
anything that's not an ordinary identifier (thus, the initializer
cannot declare a tag or the members of a structure or union), while
making it undefined behavior for it to declare more than one
ordinary identifier. (For the latter, while I keep the existing
error from __auto_type in the case of more than one declarator, I
don't restrict other ordinary identifiers from being declared in
inner scopes such as GNU statement expressions. I do however
disallow defining the members of an enumeration inside the
initializer (if the enum definition has no tag, that doesn't
actually violate a constraint), to avoid an enum type becoming
accessible beyond where it would have been without auto.
(Preventing new types from escaping the initializer - thus, ensuring
that anything written with auto corresponds to something that could
have been written without auto, modulo multiple evaluation of VLA
size expressions when not using auto - is a key motivation for some
restrictions on what can be declared in the initializer.)
The rule on shadowing and restrictions on other declarations in the
initializer are actually general rules for what C2x calls
underspecified declarations, a description that covers constexpr as
well as auto (in particular, this disallows a constexpr initializer
from referencing the variable being initialized). Thus, some of the
code added for those restrictions will also be of use in implementing
C2x constexpr.
auto with a type specifier remains a storage class specifier with the
same meaning as before (i.e. a redundant storage class specifier for
use at block scope).
Note that the feature is only enabled in C2x mode (-std=c2x or
-std=gnu2x); in older modes, a declaration with auto and no type is
treated as a case of implicit int (only accepted at block scope).
Since many of the restrictions on C2x auto are specified as undefined
behavior rather than constraint violations, it would be possible to
support more features from C++ auto without requiring diagnostics (but
maybe not a good idea, if it isn't clear exactly what semantics might
be given to such a feature in a future revision of C; and
-Wc23-c2y-compat should arguably warn for any such future feature
anyway). For now the features are limited to something close to
what's supported with __auto_type, with the differences as discussed
above between the two features.

C2x allows function prototypes to be given as (...), a prototype
meaning a variable-argument function with no named arguments. To
allow such functions to access their arguments, requirements for
va_start calls are relaxed so it ignores all but its first argument
(i.e. subsequent arguments, if any, can be arbitrary pp-token
sequences).
Implement this feature accordingly. The va_start relaxation in
<stdarg.h> is itself easy: __builtin_va_start already supports a
second argument of 0 instead of a parameter name, and calls get
converted internally to the form using 0 for that argument, so
<stdarg.h> just needs changing to use a variadic macro that passes 0
as the second argument of __builtin_va_start. (This is done only in
C2x mode, on the expectation that users of older standard would expect
unsupported uses of va_start to be diagnosed.)
For the (...) functions, it's necessary to distinguish these from
unprototyped functions, whereas previously C++ (...) functions and
unprototyped functions both used NULL TYPE_ARG_TYPES. A flag is added
to tree_type_common to mark the (...) functions; as discussed on gcc@,
doing things this way is likely to be safer for unchanged code in GCC
than adding a different form of representation in TYPE_ARG_TYPES, or
adding a flag that instead signals that the function is unprototyped.
There was previously an option
-fallow-parameterless-variadic-functions to enable support for (...)
prototypes. The support was incomplete - it treated the functions as
unprototyped, and only parsed some declarations, not e.g.
"int g (int (...));". This option is changed into a no-op ignored
option; (...) is always accepted syntactically, with a pedwarn_c11
call to given required diagnostics when appropriate. The peculiarity
of a parameter list with __attribute__ followed by '...' being
accepted with that option is removed.
Interfaces in tree.cc that create function types are adjusted to set
this flag as appropriate. It is of course possible that some existing
users of the functions to create variable-argument functions actually
wanted unprototyped functions in the no-named-argument case, rather
than functions with a (...) prototype; some such cases in c-common.cc
(for built-in functions and implicit function declarations) turn out
to need updating for that reason.
I didn't do anything to change how the C++ front end creates (...)
function types. It's very likely there are unchanged places in the
compiler that in fact turn out to need changes to work properly with
(...) function prototypes.
Target setup_incoming_varargs hooks, where they used the information
passed about the last named argument, needed updating to avoid using
that information in the (...) case. Note that apart from the x86
changes, I haven't done any testing of those target changes beyond
building cc1 to check for syntax errors. It's possible further
target-specific fixes will be needed; target maintainers should watch
out for failures of c2x-stdarg-4.c or c2x-stdarg-split-1a.c, the
execution tests, which would indicate that this feature is not working
correctly. Those tests also verify the case where there are named
arguments but the last named argument has a declaration that results
in undefined behavior in previous C standard versions, such as a type
changed by the default argument promotions.

C2x adds support for enums with a fixed underlying type specified
("enum e : long long;" and similar). Implement this in the C front
end. The same representation is used for these types as in C++, with
two macros moved from cp-tree.h to c-common.h.
Such enums can have bool as the underlying type, and various C
front-end code checking for boolean types is adjusted to use a new
C_BOOLEAN_TYPE_P to handle such enums the same way as bool. (Note
that for C++ we have bug 96496 that enums with underlying type bool
don't work correctly there.)
There are various issues with the wording for such enums in the
current C2x working draft (including but not limited to wording in the
accepted paper that failed to make it into the working draft), which I
intend to raise in NB comments. I think what I've implemented and
added tests for matches the intent.

As noted in bug 101764, a declaration "enum tag;" is invalid in
standard C after a definition, as well as when no definition is
visible; we had a pedwarn-if-pedantic for the forward declaration
case, but were missing one for the other case. Add that missing
diagnostic (if pedantic only).
(These diagnostics will need to be appropriately conditioned when
support is added for C2x enums with fixed underlying type, since "enum
tag : type;" is OK both before and after a definition.)

C2x has two enhancements to enumerations: allowing enumerations whose
values do not all fit in int (similar to an existing extension), and
allowing an underlying type to be specified (as in C++). This patch
implements the first of those enhancements.
Apart from adjusting diagnostics to reflect this being a standard
feature, there are some semantics differences from the previous
extension:
* The standard feature gives all the values of such an enum the
enumerated type (while keeping type int if that can represent all
values of the enumeration), where previously GCC only gave those
values outside the range of int the enumerated type. This change
was previously requested in PR 36113; it seems unlikely that people
are depending on the detail of the previous extension that some
enumerators had different types to others depending on whether their
values could be represented as int, and this patch makes the change
to types of enumerators unconditionally (if that causes problems in
practice we could always make it conditional on C2x mode instead).
* The types *while the enumeration is being defined*, for enumerators
that can't be represented as int, are now based more directly on the
types of the expressions used, rather than a possibly different type
with the right precision constructed using c_common_type_for_size.
Again, this change is made unconditionally.
* Where overflow (or wraparound to 0, in the case of an unsigned type)
when 1 is implicitly added to determine the value of the next
enumerator was previously an error, it now results in a wider type
with the same signedness (as the while-being-defined type of the
previous enumerator) being chosen, if available.
When a type is chosen in such an overflow case, or when a type is
chosen for the underlying integer type of the enumeration, it's
possible that (unsigned) __int128 is chosen. Although C2x allows for
such types wider than intmax_t to be considered extended integer
types, we don't have various features required to do so (integer
constant suffixes; sufficient library support would also be needed to
define the associated macros for printf/scanf conversions, and
<stdint.h> typedef names would need to be defined). Thus, there are
also pedwarns for exceeding the range of intmax_t / uintmax_t, as
while in principle exceeding that range is OK, it's only OK in a
context where the relevant types meet the requirements for extended
integer types, which does not currently apply here.
Bootstrapped with no regressions for x86_64-pc-linux-gnu. Also
manually checked diagnostics for c2x-enum-3.c with -m32 to confirm the
diagnostics in that { target { ! int128 } } test are as expected.

Implement the C2x feature of storage class specifiers in compound
literals. Such storage class specifiers (static, register or
thread_local; also constexpr, but we don't yet have C2x constexpr
support implemented) can be used before the type name (not mixed with
type specifiers, unlike in declarations) and have the same semantics
and constraints as for declarations of named objects. Also allow GNU
__thread to be used, given that thread_local can be.

Add the following new option -fstrict-flex-arrays[=n] and a corresponding
attribute strict_flex_array to GCC:
'-fstrict-flex-arrays'
Control when to treat the trailing array of a structure as a flexible array
member for the purpose of accessing the elements of such an array.
The positive form is equivalent to '-fstrict-flex-arrays=3', which is the
strictest. A trailing array is treated as a flexible array member only when
it declared as a flexible array member per C99 standard onwards.
The negative form is equivalent to '-fstrict-flex-arrays=0', which is the
least strict. All trailing arrays of structures are treated as flexible
array members.
'-fstrict-flex-arrays=LEVEL'
Control when to treat the trailing array of a structure as a flexible array
member for the purpose of accessing the elements of such an array. The value
of LEVEL controls the level of strictness
The possible values of LEVEL are the same as for the
'strict_flex_array' attribute (*note Variable Attributes::).
You can control this behavior for a specific trailing array field
of a structure by using the variable attribute 'strict_flex_array'
attribute (*note Variable Attributes::).
'strict_flex_array (LEVEL)'
The 'strict_flex_array' attribute should be attached to the trailing
array field of a structure. It controls when to treat the trailing array
field of a structure as a flexible array member for the purposes of accessing
the elements of such an array. LEVEL must be an integer betwen 0 to 3.
LEVEL=0 is the least strict level, all trailing arrays of
structures are treated as flexible array members. LEVEL=3 is the
strictest level, only when the trailing array is declared as a
flexible array member per C99 standard onwards ('[]'), it is
treated as a flexible array member.
There are two more levels in between 0 and 3, which are provided to
support older codes that use GCC zero-length array extension
('[0]') or one-element array as flexible array members('[1]'): When
LEVEL is 1, the trailing array is treated as a flexible array member
when it is declared as either '[]', '[0]', or '[1]'; When
LEVEL is 2, the trailing array is treated as a flexible array member
when it is declared as either '[]', or '[0]'.
This attribute can be used with or without the
'-fstrict-flex-arrays'. When both the attribute and the option
present at the same time, the level of the strictness for the
specific trailing array field is determined by the attribute.

The following patch adds support for the begin declare target construct,
which is another spelling for declare target construct without clauses
(where it needs paired end declare target), but unlike that one accepts
clauses.
This is an OpenMP 5.1 feature, implemented with 5.2 clarification because
in 5.1 we had a restriction in the declare target chapter shared by
declare target and begin declare target that if there are any clauses
specified at least one of them needs to be to or link. But that
was of course meant just for declare target and not begin declare target,
because begin declare target doesn't even allow to/link/enter clauses.
In addition to that, the patch also makes device_type clause duplication
an error (as stated in 5.1) and similarly makes declare target with
just device_type clause an error rather than warning.
What this patch doesn't do is:
1) OpenMP 5.1 also added an indirect clause, we don't support that
neither on declare target nor begin declare target
and I couldn't find it in our features pages (neither libgomp.texi
nor web)
2) I think device_type(nohost)/device_type(host) support can't work for
variables (in 5.0 it only talked about procedures so this could be
also thought as 5.1 feature that we should just add to the list
and implement)
3) I don't see any use of the "omp declare target nohost" attribute, so
I'm not sure if device_type(nohost) works at all

C2x adds a standard [[noreturn]] attribute (which can also be spelt
[[_Noreturn]] for use with <stdnoreturn.h>), so allowing non-returning
functions to be declared in a manner compatible with C++; the
_Noreturn function specifier remains available but is marked
obsolescent.
Implement this attribute. It's more restricted than GNU
__attribute__ ((noreturn)) - that allows function pointers but using
the standard attribute on a function pointer is a constraint
violation. Thus, the attribute gets its own handler that checks for a
FUNCTION_DECL before calling the handler for the GNU attribute. Tests
for the attribute are based on those for C11 _Noreturn and for other
C2x attributes.
Bootstrapped with no regressions for x86_64-pc-linux-gnu.

The following patch implements OpenMP 5.1
#pragma omp assume
#pragma omp assumes
and
#pragma omp begin assumes
#pragma omp end assumes
directive support for C and C++. Currently it doesn't remember
anything from the assumption clauses for later, so is mainly
to support the directives and diagnose errors in their use.
If the recently posted C++23 [[assume (cond)]]; support makes it
in, the intent is that this can be easily adjusted at least for
the #pragma omp assume directive with holds clause(s) to use
the same infrastructure. Now, C++23 portable assumptions are slightly
different from OpenMP 5.1 assumptions' holds clause in that C++23
assumption holds just where it appears, while OpenMP 5.1 assumptions
hold everywhere in the scope of the directive. For assumes
directive which can appear at file or namespace scope it is the whole
TU and everything that functions from there call at runtime, for
begin assumes/end assumes pair all the functions in between those
directives and everything they call and for assume directive the
associated (currently structured) block. I have no idea how to
represents such holds to be usable for optimizers, except to
make
#pragma omp assume holds (cond)
block;
expand essentially to
[[assume (cond)]];
block;
or
[[assume (cond)]];
block;
[[assume (cond)]];
for now. Except for holds clause, the other assumptions are
OpenMP related, I'd say we should brainstorm where it would be
useful to optimize based on such information (I guess e.g. in target
regions it easily could) and only when we come up with something
like that think about how to propagate the assumptions to the optimizers.

C2x has completely removed unprototyped functions, so that () now
means the same as (void) in both function declarations and
definitions, where previously that change had been made for
definitions only. Implement this accordingly.
This is a change where GNU/Linux distribution builders might wish to
try builds with a -std=gnu2x default to start early on getting old
code fixed that still has () declarations for functions taking
arguments, in advance of GCC moving to -std=gnu2x as default maybe in
GCC 14 or 15; I don't know how much such code is likely to be in
current use.

This patch implements the C23 nullptr literal:
<https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3042.htm> (with
wording fixes from N3047), which is intended to replace the problematic
definition of NULL which might be either of integer type or void*.
Since C++ has had nullptr for over a decade now, it was relatively easy
to just move the built-in node definitions from the C++ FE to the C/C++
common code. Also, our DWARF emitter already handles NULLPTR_TYPE by
emitting DW_TAG_unspecified_type. However, I had to handle a lot of
contexts such as ?:, comparison, conversion, etc.
There are some minor differences, e.g. in C you can do
bool b = nullptr;
but in C++ you have to use direct-initialization:
bool b{nullptr};
And I think that
nullptr_t n = 0;
is only valid in C++.
Of course, C doesn't have to handle mangling, RTTI, substitution,
overloading, ...
This patch also defines nullptr_t in <stddef.h>. However, it does not
define __STDC_VERSION_STDDEF_H__ yet, because we don't know yet what value
it should be defined to.

feature accordingly. The basic case was already supported and so just
needed diagnostic adjustments. However, the standard feature also
includes two cases that were not previously supported: empty
initializer braces for scalars, and empty initializer braces for
VLAs. Thus, add support for those features as well, updating existing
tests that expected them to be diagnosed.
There was already some gimplifier support for converting
variable-sized initializations with empty CONSTRUCTORs to memset.
However, it didn't apply here; code earlier in gimplify_modify_expr
ended up calling gimplify_init_constructor via
gimplify_modify_expr_rhs, which ended up handling the CONSTRUCTOR in a
way that generated an ICE later. Add a check for this case earlier in
gimplify_modify_expr to avoid that issue.
Bootstrapped with no regressions for x86_64-pc-linux-gnu.

Whilst working on SARIF output I noticed some places where followup notes
weren't being properly associated with their errors/warnings in c-decl.cc.
Whilst fixing those I noticed some places where we "inform" after a
"warning" without checking that the warning was actually emitted.
Fixed the various issues seen in gcc/c/c-decl.cc thusly.

In C, an enumerated type is compatible with char, a signed integer type,
or an unsigned integer type (6.7.2.2/5). Therefore this code compiles:
enum E { l = -1, z = 0, g = 1 };
int foo(void);
enum E foo(void) { return z; }
if the underlying type of 'enum E' is 'int' (if not, we emit an error).
This is different for typedefs, where C11 permits typedefs to be
redeclared to the same type, but not to compatible types. In C++, the
code above is invalid.
It seems desirable to emit a warning in the C case, because it is
probably a mistake and definitely a portability error, given that the
choice of the underlying type is implementation-defined.
To that end, this patch implements a new -Wenum-int-mismatch warning.
Conveniently, we already have comptypes_check_enum_int to detect such
mismatches. This warning is enabled by either -Wall or -Wc++-compat.

The C and C++ FEs differ in TYPE_VALUES for an enum type: an entry in
the list in the C++ FE has a CONST_DECL in the TREE_VALUE, but the C FE
has only the numerical value of the CONST_DECL there. This has caused
me some trouble in my PR105497 patch. Using a CONST_DECL is preferable
because a CONST_DECL can track more information (e.g., attributes), and
you can always get the value simply by looking at its DECL_INITIAL.
This turned out to be a trivial change. One place in godump.cc had to be
adjusted. I'm not changing the CONST_DECL check in c_do_switch_warnings
because I'll be changing it soon in my next patch. I didn't see any other
checks that this patch makes redundant.

* c-decl.cc (finish_enum): Store the CONST_DECL into TREE_VALUE, not
its value.

* godump.cc (go_output_typedef): Use the DECL_INITIAL of the TREE_VALUE.
