[PATCH v5] gcc, libcpp: Add warning switch for "#pragma once in main file" [PR89808]

[Ken Matsui]

This patch adds a warning switch for "#pragma once in main file".  The
warning option name is Wpragma-once-outside-header, which is the same
as Clang provides.

PR preprocessor/89808

gcc/c-family/ChangeLog:

* c.opt (Wpragma_once_outside_header): Define new option.
* c.opt.urls: Regenerate.

gcc/ChangeLog:

* doc/invoke.texi (Warning Options): Document
-Wno-pragma-once-outside-header.

libcpp/ChangeLog:

* include/cpplib.h (cpp_warning_reason): Define
CPP_W_PRAGMA_ONCE_OUTSIDE_HEADER.
* directives.cc (do_pragma_once): Use
CPP_W_PRAGMA_ONCE_OUTSIDE_HEADER.

gcc/testsuite/ChangeLog:

* g++.dg/warn/Wno-pragma-once-outside-header.C: New test.
* g++.dg/warn/Wpragma-once-outside-header.C: New test.

--- Comment #12 from Jeffrey A. Law  ---
Reading the RTL dumps from Richard S. this looks like the exact same problem
we're still seeing on the RISC-V port, affecting 557.xz.

Specifically we get the same I2 back, but I3 has changed.  The change in I3 in
turn allows I2 to combine into a different instruction and net is a clear
improvement.  ISTM that allowing this combination when we get the same I2 back,
but a different I3 would be sufficient to fix both the aarch64 and riscv
problems.

Unfortunately Segher has gone radio silent on this issue.

  _19 = BIT_FIELD_REF ;
  _12 = BIT_FIELD_REF ;
  _15 = _12 | _19;

vs
  _13 = BIT_FIELD_REF ;
  _14 = BIT_FIELD_REF ;
  _15 = _13 | _14;

So basically it is just by accident the order happens that way which is why the
reducing it further removing the stuff afterwards does not make any difference
...

[committed] Fix minor SH scan-asm failure after recent IOR->ADD changes

This fixes minor fallout from the IOR->ADD change for rotates that I 
installed
a little while ago.

Basically the SH backend has a special pattern for setting the T register 
that
has elements similar to a rotate.  With the IOR->ADD change that pattern no
longer matches and we get scan-asm failures.

Fixing isn't a trivial case of just replacing IOR with ADD as the IOR->ADD
change changes some of the simplifications/canonicalizations along the way.

The net is we need a pattern with a slightly different structure.   I've
regression tested this on sh3[eb]-linux-gnu and bootstrapped sh4-linux-gnu
(without a regression test).

Semi-cleaned up testcase with some extra hooks

So note if you change any of the `#if 0` to `#if 1` or `#if 1` to `#if 0` the
crash in SLP no longer happens.

Note also with the last one change, the only difference deals with the PERM
that is being selected in SLP:
Due to the order of `BIT_FIELD_REF ;` vs `BIT_FIELD_REF
;`. somehow.

[PATCH] c++/modules: Ensure deduction guides are always reachable [PR115231]

[Nathaniel Shead]

Bootstrapped and regtested on x86_64-pc-linux-gnu, OK for trunk?

This probably isn't the most efficient approach, since we need to do
name lookup to find deduction guides for a type which will also
potentially do a bunch of pointless lazy loading from imported modules,
but I wasn't able to work out a better approach without completely
reworking how deduction guides are stored and represented.  This way at
least is correct (I believe), and we can maybe revisit this in the
future.

-- >8 --

Deduction guides are represented as 'normal' functions currently, and
have no special handling in modules.  However, this causes some issues;
by [temp.deduct.guide] a deduction guide is not found by normal name
lookup and instead all reachable deduction guides for a class template
should be considered, but this does not happen currently.

To solve this, this patch ensures that all deduction guides are
considered exported to ensure that they are always visible to importers
if they are reachable.  Another alternative here would be to add a new
kind of "all reachable" flag to name lookup, but that is complicated by
some difficulties in handling GM entities; this may be a better way to
go if more kinds of entities end up needing this handling, however.

Another issue here is that because deduction guides are "unrelated"
functions, they will usually get discarded from the GMF, so this patch
ensures that when finding dependencies, GMF deduction guides will also
have bindings created.  We do this in find_dependencies so that we don't
unnecessarily create bindings for GMF deduction guides that are never
reached; for consistency we do this for *all* deduction guides, not just
GM ones.

Finally, when merging deduction guides from multiple modules, the name
lookup code may now return two-dimensional overload sets, so update
callers to match.

As a small drive-by improvement this patch also updates the error pretty
printing code to add a space before the '->' when printing a deduction
guide, so we get 'S(int) -> S' instead of 'S(int)-> S'.

PR c++/115231

gcc/cp/ChangeLog:

* error.cc (dump_function_decl): Add a space before '->' when
printing deduction guides.
* module.cc (depset::hash::add_binding_entity): Skip deduction
guides here.
(depset::hash::add_deduction_guides): New.
(depset::hash::find_dependencies): Add deduction guide
dependencies for a class template.
(module_state::write_cluster): Always consider deduction guides
as exported.
* pt.cc (deduction_guides_for): Use 'lkp_iterator' instead of
'ovl_iterator'.

[PATCH] c++: Simplify uses of LAMBDA_EXPR_EXTRA_SCOPE

[Nathaniel Shead]

No functional change intended; OK for trunk?

-- >8 --

I noticed there already exists a getter to get the scope of a lambda
from its type directly rather than needing to go via
CLASSTYPE_LAMBDA_EXPR, we may as well use it.

gcc/cp/ChangeLog:

* module.cc (trees_out::get_merge_kind): Use
LAMBDA_TYPE_EXTRA_SCOPE instead of LAMBDA_EXPR_EXTRA_SCOPE.
(trees_out::key_mergeable): Likewise.

Thank you. Patches look good to me, pushed to master branch.

[gcc r15-1356] pretty-print: Don't translate escape sequences to windows console API

pretty-print: Don't translate escape sequences to windows console API

Modern versions of windows (after windows 10 v1511) support VT100 escape
sequences, so translation for them is not necessary. The translation also
mangles embedded warning documentation links.

gcc/ChangeLog:
* pretty-print.cc (mingw_ansi_fputs): Don't translate escape 
sequences if
the console has ENABLE_VIRTUAL_TERMINAL_PROCESSING.

[gcc r15-1355] diagnostics: Don't hardcode auto_enable_urls to false for mingw hosts

diagnostics: Don't hardcode auto_enable_urls to false for mingw hosts

Windows terminal and mintty both have support for link escape sequences, 
and so
auto_enable_urls shouldn't be hardcoded to false. For older versions of the
windows console, mingw_ansi_fputs's console API translation logic does 
mangle
these sequences, but there's nothing useful it could do even if this weren't
the case, so check if the ansi escape sequences are supported at all.

conhost.exe doesn't support link escape sequences, but printing them does 
not
cause any problems.

gcc/ChangeLog:
* diagnostic-color.cc (auto_enable_urls): Don't hardcode to return
false on mingw hosts.
(auto_enable_urls): Return true if console
supports ansi escape sequences.

[PATCH v4] gcc, libcpp: Add warning switch for "#pragma once in main file" [PR89808]

[Ken Matsui]

This patch adds a warning switch for "#pragma once in main file".  The

[Bug ada/115507] New: 'Wide_Wide_Value failed for unicode strings

[dramwang at 163 dot com via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115507

Bug ID: 115507
   Summary: 'Wide_Wide_Value failed for unicode strings
   Product: gcc
   Version: 15.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: ada
  Assignee: unassigned at gcc dot gnu.org
  Reporter: dramwang at 163 dot com
CC: dkm at gcc dot gnu.org
  Target Milestone: ---

For following code, CONSTRAINT_ERROR exception will be raised:

```
with Ada.Wide_Wide_Text_IO ;

procedure Sample is
   use Ada.Wide_Wide_Text_IO ;

   type T is (A, 乙) ;
begin
   Put_Line (A'Wide_Wide_Image) ;
   Put_Line (乙'Wide_Wide_Image) ;

   Put_Line (T (T'Wide_Wide_Value ("A"))'Wide_Wide_Image) ;
   Put_Line (T (T'Wide_Wide_Value ("乙"))'Wide_Wide_Image) ;
end Sample ;
```

Output:

```
A
乙  
   A

raised CONSTRAINT_ERROR : bad input for 'Value: "乙"

Fixed on the trunk, I suspect r15-917-gc9842f99042454 fixed it.
That revision is explictly fixing `POLY_INT_CST [16, 16] /[ex] 16` case too.

I think we should just add the testcase and close it as fixed.

As an aside, simulavr tries to simulate an exact match of the hardware
including internal I/O like timers, IRQs, etc.

For GCC regression testing, no internal I/O is needed; all what's
required for testing algorithms is a core simulator like avrtest:

https://github.com/sprintersb/atest

https://github.com/sprintersb/atest?tab=readme-ov-file#running-the-avr-gcc-testsuite-using-the-avrtest-simulator

avrtest runs orders of magnitude faster than simulavr, however it
doesn't implement a GDB server, EEPROM or timers (none of which
is required for the GCC testsuite).


Thanks for the pointer.


Apart from that, only being a core simulator, you can test for more
cores than covered by simulavr.  simulavr supports devices that cover
the following 8 multilib variants:

avr2
tiny-stack
avr25
avr25/tiny-stack
avr4
avr5
avr51
avr6

out of the 19 variants available in avr-gcc, like avr3, avr31,
avrtiny, and all the avrxmega[2-7] variants that can be used with
avrtest.


avr-gcc 15 actually has 57 multilib variants (long-double32,
double64 and short-calls versions).

avr-libc 2.2.0 uses -print-multi-lib to build them all,
avr-libc 2.0.0 has only 17 variants hardcoded.

But right now I'm fighting against an ICE in cmath, i.e. so far
any tests of cmath fail...

I'll investigate this tomorrow and decide then what I'll do...

gawk and sed were potential host modules at one point previously, too, but it
looks like they've been removed, so yeah I guess it'd be safe for them now...
anything that might fall in this category should get checked against
Makefile.def to make sure there aren't already potential modules for them for
people trying to combine trees or something...

In reality there are tons of changes, people add new options even on release
branches all the time.

So I think it is very useful to have separate documentation for the separate
releases.

Already before this thread, but definitely now, I started to wonder 
whether we shouldn't fundamentally change our approach on online 
documentation for release branches.

My proposal is to have only one version per release branch online,
that is, not https://gcc.gnu.org/onlinedocs/gcc-14.1.0 and
https://gcc.gnu.org/onlinedocs/gcc-14.2.0 and so forth, rather just

  https://gcc.gnu.org/onlinedocs/gcc-14

There should be *very* few user visible changes such as new options or 
substantially different behaviors on release branches - pretty much by 
definition.

So why not have one version of the documentation per release branch where 
users of 14.1 get documentation fixes/improvements made for later in the
branch?

And it would vastly simplify things in terms of creating docs - simply 
build them once a day, no changes for point releases... (and much, much
less duplication).

What do you think?

added.

I suspect the fix for PR 96917 broke references (or rather changed all to be
non references).

It looks like the abseil code is not using __is_pointer directly at all, but
rather the standard headers here. I suspect we should just rename the
__is_pointer template to workaround this clang oddness (and add a comment on
why the name is not __is_pointer).

Re: [PATCH v1] RISC-V: Add testcases for vector unsigned SAT_SUB form 2

From: Pan Li 

The previous RISC-V backend .SAT_SUB enabling patch missed the form 2
testcases of vector modes.  Aka:

Form 2:
   #define DEF_VEC_SAT_U_SUB_FMT_2(T)   \
   void __attribute__((noinline))   \
   vec_sat_u_sub_##T##_fmt_2 (T *out, T *op_1, T *op_2, unsigned limit) \

   {\
 T x = op_1[i]; \
 T y = op_2[i]; \
 out[i] = (x - y) & (-(T)(x > y));  \
   }\
   }

This patch would like to make it up to ensure form 2 of .SAT_SUB vector
is covered.

Passed the rv64gcv rvv.exp tests.

[PATCH v2] LoongArch: Tweak IOR rtx_cost for bstrins

[Xi Ruoyao]

Consider

c &= 0xfff;
a &= ~0xfff;
b &= ~0xfff;
a |= c;
b |= c;

This can be done with 2 bstrins instructions.  But we need to recognize
it in loongarch_rtx_costs or the compiler will not propagate "c & 0xfff"
forward.

gcc/ChangeLog:

* config/loongarch/loongarch.cc:
(loongarch_use_bstrins_for_ior_with_mask): Split the main logic
into ...
(loongarch_use_bstrins_for_ior_with_mask_1): ... here.
(loongarch_rtx_costs): Special case for IOR those can be
implemented with bstrins.

gcc/testsuite/ChangeLog;

* gcc.target/loongarch/bstrins-3.c: New test.
---

Bootstrapped and regtested on loongarch64-linux-gnu.  Ok for trunk?

-Wcast-qual consistency with initialization conversion and double pointer types

[Ryan Libby via Gcc]

I'm not a C language expert and I'm looking for advice on whether a
-Wcast-qual diagnostic in one situation and not another is intentional
behavior.

Here's a set of examples (same as attachment).

% cat cast-qual-example.c
#define F(name, type, qual) \
typedef type t_##name;  \
void name(void) {   \
t_##name x = 0, y, z;   \
y = *(t_##name qual *)   \
z = *(t_##name qual *){}; \
}

F(fcc, char, const)
F(fpc, char *, const)
F(fcv, char, volatile)
F(fpv, char *, volatile)

void fpv2(void) {
char *x = 0, *y, *z;
y = *(char * volatile *)
z = *(char * volatile *){};
}

void eg1(void) {
/* Adapted from -Wcast-qual doc */
char v0 = 'v';
char *v1 = 
char **p = 
/* p is char ** value.  */
char * volatile *q = (char * volatile *) p;
/* Assignment of volatile pointer to char is OK. */
char u0 = 'u';
char * volatile u1 = 
*q = u1;
/* Now *q is accessed through a non-volatile-qualified pointer. */
*p = 0;
}

void eg2(void) {
char v = 'v';
char *p = 
/* p is char * value.  */
char volatile *q = (char volatile *) p;
/* Assignment of volatile char is OK (and also plain char). */
char volatile u = 'u';
*q = u;
/* Now *q is accessed through a non-volatile-qualified pointer. */
*p = 0;
}

%

The macro and typedef are to illustrate the point, they aren't otherwise
needed, and fpv2 shows the same thing without them.

So, in the conversion of char ** to char * volatile *, the cast before
the assignment of y is diagnosed, but the conversion in the
initialization of the compound literal for the assignment of z is not.

First, is the cast construct actually different from the initialization
construct in terms of safety?  I would think not, but maybe I am
missing something.

I think that both assignment expressions in fpv as a whole are
ultimately safe, considering also the immediate dereference of the
temporary outer pointer value.

In eg1 and eg2 I modified examples from the -Wcast-qual documentation.
eg1 is diagnosed, eg2 is not.

I think that the *p assignment in eg1 might be undefined behavior
(6.7.3, referring to an object with volatile-qualified type (*q) through
an lvalue without volatile-qualified type (*p)).

But then I don't get why the same wouldn't be true if we take away the
inner pointer and repeat the exercise with plain char (eg1 vs eg2).

So, what's going on here?  Is the gcc behavior intentional?  Is it
consistent?  And is there a recommended way to construct a temporary
volatile pointer to an object (which may itself be a pointer) without
tripping -Wcast-qual, without just casting away type information (as in,
without intermediate casts through void *, uintptr_t, etc), and
preferably also without undefined behavior?

I have checked that the behavior is the same with current sources and
-std=c23 (gcc (GCC) 15.0.0 20240614 (experimental)).

P.s. I have seen gcc bug 84166 that advises that the -Wcast-qual warning
from the cast is intentional in that case.  I think this case is
different because in that case the qualifiers are on the innermost type.

Thank you,

Ryan Libby

--- Comment #9 from Jonathan Wakely  ---
Changing libstdc++ order of includes won't help abseil. If their use of
__is_pointer still comes after any standard header has included
cpp_type_traits.h, the identifier will be "poisoned" by the class template. So
they need their own workaround.

Thanks, this script is useful. FWIW I think the patch is there, line 778?
Unless I am missing something.

I see you also commented out the assert in your recipe. I am still not sure if
that is just masking some deeper issue, but I am getting close to being able to
reproduce it myself and will let you know.

Re: [C PATCH, v3] Fix for redeclared enumerator initialized with different type [PR115109]

[Martin Uecker]

The patch fails on arm because the tests make assumptions
about enums that are not true everywhere. Should we just 
limit the tests to x86?

[Bug other/115506] New: Possible but missed "cmp" instruction merging (x86 & ARM, optimization)

[Explorer09 at gmail dot com via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115506

Bug ID: 115506
   Summary: Possible but missed "cmp" instruction merging (x86 &
ARM, optimization)
   Product: gcc
   Version: 14.1.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: other
  Assignee: unassigned at gcc dot gnu.org
  Reporter: Explorer09 at gmail dot com
  Target Milestone: ---

I'm not sure if the GCC developers are interested in this optimization or if
this issue has been reported before.



(Compiler Explorer link: https://godbolt.org/z/vqqf865cb)

```c
#include 

// Modified from 
uint32_t utf8_to_code_point(const uint8_t **sequence) {
if (**sequence <= 0x7F) {
return *(*sequence)++;
}

unsigned int max_length;
uint32_t min_code_point;
if ((**sequence & 0xF0) == 0xE0) { /* NOTE 0 */
max_length = 3;
min_code_point = 0x0800;
} else if ((**sequence & 0xF0) < 0xE0) { /* NOTE 1 */
max_length = 2;
min_code_point = 0x80;
} else {
max_length = 4;
min_code_point = 0x1;
}

uint32_t code_point = (uint32_t)**sequence - (0xFF & ~(0xFF >>
max_length));
while (1) {
(*sequence)++;
if (--max_length == 0) {
break;
}
unsigned int code_offset = (unsigned int)**sequence - 0x80;
if (code_offset > 0x3F) {
return (uint32_t)-1;
}
code_point = (code_point << 6) + code_offset;
}

if (code_point < min_code_point) {
return (uint32_t)-1;
}
if (code_point >= 0xD800 && code_point <= 0xDFFF) {
return (uint32_t)-1;
}
return code_point;
}
```

I wrote this code with the expectation that the compiler can optimize the "cmp"
 instructions so that the same compare status can be used twice.

But instead I get this:

```x86asm
#   ...
movl%eax, %ecx
andl$-16, %ecx
cmpb$-32, %cl
je  .L8
cmpb$-33, %cl
ja  .L9
#   ...
```

The immediate constant for the second "cmp" instruction gets modified
off-by-one (I can guess the reason for that) and missed this particular chance
of merging the comparisons.

A workaround is to modify the line marked with the `/* NOTE 1 */` comment to
use `<=` instead of `<`. But I wish GCC can detect this optimization
opportunity better.

possible solution patch

At the moment GCC emits two ldr/str instructions for DI/DF modes load/store.
However there's a trick to use ldmia/stmia when address register in not
used anymore/dead or reused.

I don't know if it affects arm and/or thumb2 as well.
Patch for possible solution for thumb1 provided.

Comparing code size with the patch gives for v6-m/nofp:

[PATCH] LoongArch: Only transform move/move/bstrins to srai/bstrins when -Os

[Xi Ruoyao]

The first form has a lower latency (due to the special handling of
"move" in LA464 and LA664) despite it's longer.

gcc/ChangeLog:

* config/loongarch/loongarch.md (define_peephole2): Require
optimize_insn_for_size_p () for move/move/bstrins =>
srai/bstrins transform.

[PATCH] LoongArch: Tweak IOR rtx_cost for bstrins

[Xi Ruoyao]

Consider

c &= 0xfff;
a &= ~0xfff;
b &= ~0xfff;
a |= c;
b |= c;

This can be done with 2 bstrins instructions.  But we need to recognize
it in loongarch_rtx_costs or the compiler will not propagate "c & 0xfff"
forward.

gcc/ChangeLog:

* config/loongarch/loongarch.cc:
(loongarch_use_bstrins_for_ior_with_mask): Split the main logic
into ...
(loongarch_use_bstrins_for_ior_with_mask_1): ... here.
(loongarch_rtx_costs): Special case for IOR those can be
implemented with bstrins.

gcc/testsuite/ChangeLog;

* gcc.target/loongarch/bstrins-3.c: New test.

-Wxxx shouldn't have an effect on code generation.  -fno-lifetime-dse is quite

Not necessarily. Since GCC v10, the default for long double is 64 bit (IEEE
double), but [long] double is also switchable per -m[long-]double={32,64}.

RISC-V: Add testcases for vector unsigned SAT_SUB form 2

The previous RISC-V backend .SAT_SUB enabling patch missed the form 2
testcases of vector modes.  Aka:

Form 2:
  #define DEF_VEC_SAT_U_SUB_FMT_2(T)   \
  void __attribute__((noinline))   \
  vec_sat_u_sub_##T##_fmt_2 (T *out, T *op_1, T *op_2, unsigned limit) \
  {\
unsigned i;\
for (i = 0; i < limit; i++)\
  {\
T x = op_1[i]; \
T y = op_2[i]; \
out[i] = (x - y) & (-(T)(x > y));  \
  }\
  }

This patch would like to make it up to ensure form 2 of .SAT_SUB vector
is covered.

Passed the rv64gcv rvv.exp tests.

Re: [PATCH] libstdc++: Do not use memset _Hashtable buckets allocation

[François Dumont]

Here is the simplified patch then.

    libstdc++: Do not use memset in _Hashtable buckets allocation

    Using memset is incorrect if the __bucket_ptr type is non-trivial, or
    does not use an all-zero bit pattern for its null value.

    Replace the use of memset with std::__uinitialized_default_n to set the
    pointers to nullptr. Doing so and corresponding std::_Destroy_n 
when deallocating

    buckets.

    libstdc++-v3/ChangeLog:

    * include/bits/hashtable_policy.h
    (_Hashtable_alloc::_M_allocate_buckets): Do not use memset 
to zero

    out bucket pointers.
    (_Hashtable_alloc::_M_deallocate_buckets): Add destroy of 
buckets.


Tested under Linux x64, ok to commit ?

Hi

Following your recent change here:

https://gcc.gnu.org/pipermail/libstdc++/2024-June/058998.html

I think we also need to fix the memset at bucket allocation level.

I did it trying also to be more fancy pointer friendly by running
__uninitialized_default_n_a on the allocator returned pointer rather
than on the __to_address result. I wonder if an __uninitialized_fill_n_a
would have been better ? Doing so I also had to call std::_Destroy on
deallocation. Let me know if it is too early.

You don't need the RAII guard. Initializing Alloc::pointer isn't
allowed to throw exceptions:

"An allocator type X shall meet the Cpp17CopyConstructible
requirements (Table 32). The XX::pointer,
XX::const_pointer, XX::void_pointer, and XX::const_void_pointer types
shall meet the Cpp17Nullable-
Pointer requirements (Table 36). No constructor, comparison operator
function, copy operation, move
operation, or swap operation on these pointer types shall exit via an
exception."

And you should not pass the allocator to the __uninitialized_xxx call,
nor the _Destroy call. We don't want to use the allocator's
construct/destroy members for those pointers. They are not container
elements.

I think either uninitialized_fill_n with nullptr or
__uninitialized_default_n is fine. Not the _a forms taking an
allocator though.

And I'd use _Destroy_n(_M_buckets, _M_bucket_count)



I also wonder if the compiler will be able to optimize it to a memset
call ? I'm interested to work on it if you confirm that it won't.

It will do whatever is fastest, which might be memset or might be
vectorized code to zero it out (which is probably what libc memset
does too).

--- Comment #8 from Arthur O'Dwyer  ---
FWIW, I also ran into this, this morning.
Reduced: https://godbolt.org/z/rxYKTqKd4
Organically in Abseil: https://godbolt.org/z/9eoqKzYjc
(This happens because Abseil #includes  before 
(alphabetically). If you switch the order of those two includes, it Just
Works.)

IMVHO libstdc++ should do jwakely's idea of #include  from the
offending header file; that's the most foolproof O(1) solution, rather than the
O(N) solution of being really careful to always write `bool(__is_foo(T))`
instead of `__is_foo(T)`. Also, there are definitely third-party libraries
(like Abseil) out there who legitimately want to use `__is_pointer(T)` in their
own code, and right now they have no idea that they ought to write all their
uses with an extra `bool` cast just to work around a problematic interaction
between Clang and libstdc++ (a mode they probably don't even build in their
CI). So fixing the problem once and for all on libstdc++'s side of the fence
would be really helpful.

[Bug c++/115504] New: Wrong decltype result for a captured reference inside limbda

[fchelnokov at gmail dot com via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115504

Bug ID: 115504
   Summary: Wrong decltype result for a captured reference inside
limbda
   Product: gcc
   Version: 14.1.1
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: fchelnokov at gmail dot com
  Target Milestone: ---

This program
```
template int foo() = delete;
template<> int foo() { return 0; }

int main() { 
int y = 0;
int  = y;
return []() {
decltype(auto) x = i;
return foo();
}();
}
```
is accepted in Clang, MSVC and GCC 13.3, but not in GCC 14, which thinks that
`decltype(x)=int`. Online demo: https://gcc.godbolt.org/z/fc1nrP4P9
