[Bug middle-end/114912] [15 regression] SIGBUS in wi::copy<> on SPARC

--- Comment #6 from Andrew Pinski  ---
I might see if I can figure out a patch for some to try later tonight.

I see the issue then.
char m_buffer[sizeof (int_range_max)];

Needs _Align to get the alignment correct.

I doubt this can be seen in a cross: running the compilation under truss
reveals
the SIGBUS as

2834:   Incurred fault #5, FLTACCESS  %pc = 0x00723E58
2834: siginfo: SIGBUS BUS_ADRALN addr=0xFFBFC954
2834:   Received signal #10, SIGBUS [caught]
2834: siginfo: SIGBUS BUS_ADRALN addr=0xFFBFC954

i.e. an unaligned access.  While SPARC is a strict-alignment target, x86 cares
little if any about alignment at all.

Supporting this seems better than forcing the user to work around by providing
an incorrect size such as (0, 0).

[PATCH] c++: Clear is_unbraced_* when parsing declaration_seq_opt [PR114917]

[Nathaniel Shead]

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

-- >8 --

Currently we incorrectly retain "in_unbraced_linkage_specification_p"
and "in_unbraced_export_declaration_p" when parsing a (braced)
declaration-seq.  This patch ensures that we clear these flags before
parsing the toplevel declarations.

Strictly speaking we don't need to save and restore the flags around the
parsing because there's currently no way to provide new declarations
within the unbraced context after the closing brace, but this patch does
it anyway in case this ever changes and for consistency with other
places where these flags are adjusted.

PR c++/114917

gcc/cp/ChangeLog:

* parser.cc (cp_parser_declaration_seq_opt): Clear
parser->in_unbraced_* flags when parsing toplevel declarations.

gcc/testsuite/ChangeLog:

* g++.dg/modules/export-5_a.C: New test.
* g++.dg/modules/export-5_b.C: New test.
* g++.dg/parse/linkage4.C: New test.

rs6000: Add OPTION_MASK_POWER8 [PR101865]

The bug in PR101865 is the _ARCH_PWR8 predefine macro is conditional upon
TARGET_DIRECT_MOVE, which can be false for some -mcpu=power8 compiles if the
-mno-altivec or -mno-vsx options are used.  The solution here is to create
a new OPTION_MASK_POWER8 mask that is true for -mcpu=power8, regardless of
Altivec or VSX enablement.

Unfortunately, the only way to create an OPTION_MASK_* mask is to create
a new option, which we have done here, but marked it as WarnRemoved since
we do not want users using it.  For stage1, we will look into how we can
create ISA mask flags for use in the compiler without the need for explicit
options.

rs6000: Replace OPTION_MASK_DIRECT_MOVE with OPTION_MASK_P8_VECTOR 
[PR101865]

This is a cleanup patch in preparation to fixing the real bug in PR101865.
TARGET_DIRECT_MOVE is redundant with TARGET_P8_VECTOR, so alias it to that.
Also replace all usages of OPTION_MASK_DIRECT_MOVE with 
OPTION_MASK_P8_VECTOR
and delete the now dead mask.

rs6000: Replace OPTION_MASK_DIRECT_MOVE with OPTION_MASK_P8_VECTOR
[PR101865]

This is a cleanup patch in preparation to fixing the real bug in PR101865.
TARGET_DIRECT_MOVE is redundant with TARGET_P8_VECTOR, so alias it to that.
Also replace all usages of OPTION_MASK_DIRECT_MOVE with
OPTION_MASK_P8_VECTOR
and delete the now dead mask.

So he was responding for how to do it for the vectorizer and scalar parts.
Remember that the goal is not to introduce new gimple IL that can block other 
optimizations.
The vectorizer already introduces new IL (various IFN) but this is fine as we 
don't track things like ranges for
vector instructions.  So we don't loose any information here.

Now for the scalar, if we do an early replacement like in match.pd we prevent a 
lot of other optimizations
because they don't know what IFN_SAT_ADD does. gimple-isel runs pretty late, 
and so at this point we don't
expect many more optimizations to happen, so it's a safe spot to insert more IL 
with "unknown semantics".

Was that your intention Richi?

Thanks,
Tamar

Sure thing, will rearrange the patch like this.

I see, will remove that.

If I understand is correct, Richard suggested try vectorizer patterns first and 
then possible isel.
Thus, I don't have a try for SAT_ADD in ISEL as vectorizer patterns works well 
for SAT_ADD.
Let's wait the confirmation from Richard. Below are the original words from 
previous mail for reference.

Sure, will remove this.

> The function has only one caller, you should just inline it into the pattern.

Sure thing.

> Once you inline vect_sat_add_build_call you can do the check for

Sure thing.

Thanks again and will send the v4 with all comments addressed, as well as the 
test results.

This was also reported here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114912

The same question applies really, what compiler are you using to
compile GCC with? I suspect this is making a difference. It might also
be the sparc compiler that both of you two are using is causing wrong
code with some more complex C++ code even though it is at -O0.
The adding of the deconstructor to Value_Range might be causing the
structure to become a "non-POD" and different argument passing and it
was broken even at -O0 (this is just a guess).

Thanks,
Andrew Pinski

I'm seeing a crash building on sparc-sun-solaris2.11 that may be due
to this change.  The crash occurs in stage 1, the first time the newly
built compiler is used.

[Bug c++/114917] [modules] Explicit specialisations in export namespace not permitted

[Bug c++/114917] New: [modules] Explicit specialisations in export namespace not permitted

[nshead at gcc dot gnu.org via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114917

Bug ID: 114917
   Summary: [modules] Explicit specialisations in export namespace
not permitted
   Product: gcc
   Version: 15.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: nshead at gcc dot gnu.org
  Target Milestone: ---

Since r15-84-g79420dd3441458 we now incorrectly reject the following modules
example:

  export module M;
  export namespace ns {
template  void foo() {}
template <> void foo() {}
  }

Relatedly, we also incorrectly accept (and have since at least GCC 4.1):

  extern "C++" namespace ns {
struct Incomplete;
Incomplete bar;
  }

for similar reasons: the contents of the namespace are still considered be an
"unbraced" context of the extern "C++" and so bar is implicitly considered to
be declared extern.  See also [dcl.link] p8.

--- Comment #4 from Nathaniel Shead  ---
The generic C++ ABI now ignores key function determination for classes attached
to named modules.  As far as I can see the AAPCS has no wording to the
contrary, so this issue should now be resolved for GCC 15.

[gcc r15-98] c++: Implement modules ABI for vtable emissions

[Nathaniel Shead via Gcc-cvs]

https://gcc.gnu.org/g:ad30265ccfb211fca35789df2d1404cc12302219

commit r15-98-gad30265ccfb211fca35789df2d1404cc12302219
Author: Nathaniel Shead 
Date:   Tue Apr 16 22:50:26 2024 +1000

c++: Implement modules ABI for vtable emissions

This patch implements the changes described in
https://github.com/itanium-cxx-abi/cxx-abi/pull/171.

One restriction that is lifted in the ABI that hasn't been updated here
is that the ABI no longer requires unique vtables to be emitted with
vague linkage.  I haven't changed this behaviour for this patch, but in
the future we could look into changing the relevant target hook
('class_data_always_comdat') to default to 'false'.  But the current
behaviour is more forgiving to changes in key function identification.

Since the ABI for vtables attached to named modules no longer depends on
key methods, this also resolves the issue described in PR c++/105224.

PR c++/105224

gcc/cp/ChangeLog:

* class.cc (finish_struct_1): Also push classes attached to a
module into the 'keyed_classes' list.
* decl.cc (record_key_method_defined): Don't push classes
attached to a named module into the 'keyed_classes' list.
* module.cc (trees_in::read_class_def): Likewise.
* decl2.cc (import_export_class): Uniquely emit vtables for
non-template classes attached to a named module.
(vtables_uniquely_emitted): New function.
(import_export_decl): Update comments. Update with knowledge
about new kinds of uniquely emitted vtables.

gcc/testsuite/ChangeLog:

* g++.dg/modules/virt-2_a.C: Update linkage requirements.
* g++.dg/modules/virt-2_b.C: Likewise.
* g++.dg/modules/virt-2_c.C: Likewise.
* g++.dg/modules/virt-4_a.C: New test.
* g++.dg/modules/virt-4_b.C: New test.

c++: Implement modules ABI for vtable emissions

This patch implements the changes described in
https://github.com/itanium-cxx-abi/cxx-abi/pull/171.

One restriction that is lifted in the ABI that hasn't been updated here
is that the ABI no longer requires unique vtables to be emitted with
vague linkage.  I haven't changed this behaviour for this patch, but in
the future we could look into changing the relevant target hook
('class_data_always_comdat') to default to 'false'.  But the current
behaviour is more forgiving to changes in key function identification.

Since the ABI for vtables attached to named modules no longer depends on
key methods, this also resolves the issue described in PR c++/105224.

PR c++/105224

gcc/cp/ChangeLog:

* class.cc (finish_struct_1): Also push classes attached to a
module into the 'keyed_classes' list.
* decl.cc (record_key_method_defined): Don't push classes
attached to a named module into the 'keyed_classes' list.
* module.cc (trees_in::read_class_def): Likewise.
* decl2.cc (import_export_class): Uniquely emit vtables for
non-template classes attached to a named module.
(vtables_uniquely_emitted): New function.
(import_export_decl): Update comments. Update with knowledge
about new kinds of uniquely emitted vtables.

gcc/testsuite/ChangeLog:

* g++.dg/modules/virt-2_a.C: Update linkage requirements.
* g++.dg/modules/virt-2_b.C: Likewise.
* g++.dg/modules/virt-2_c.C: Likewise.
* g++.dg/modules/virt-4_a.C: New test.
* g++.dg/modules/virt-4_b.C: New test.

Here's that patch. Bootstrapped and regtested on x86_64-pc-linux-gnu, OK
for trunk/14.2?

I got notified by Linaro CI and by checking testresults that there seems
to be some occasional failures in tpl-friend-4_b.C on some architectures
and standards modes since r15-59-gb5f6a56940e708.  I haven't been able
to reproduce but looking at the backtrace I suspect the issue is that
we're adding to the 'imported_temploid_friend' map a decl that is
ultimately discarded, which then has its address reused by a later decl
causing a failure in the assert in 'set_originating_module'.

This patch fixes the problem by using DECL_UID as the map key instead of
the tree directly, much like with entity_map, since even if a
declaration gets deallocated the

[PATCH] c++/modules: Stream unmergeable temporaries by value again [PR114856]

[Nathaniel Shead]

Bootstrapped and regtested on x86_64-pc-linux-gnu, OK for trunk/14.2?

Another alternative would be to stream such !DECL_NAME temporaries with
a merge key of MK_unique rather than attempting to find the matching
(nonexistant) field of the class context.

-- >8 --

In r14-9266-g2823b4d96d9ec4 I gave all temporary vars a DECL_CONTEXT,
including those at namespace or global scope, so that they could be
properly merged across importers.  However, not all of these temporary
vars are actually supposed to be mergeable.

For instance, in the attached testcase we have an unnamed temporary var
used in the NSDMI of a class member, which cannot properly merged -- but
it also doesn't need to be, as it'll be thrown away when the class type
itself is merged anyway.

This patch reverts the change made above and instead makes a weaker
adjustment that only causes temporary vars with linkage have a
DECL_CONTEXT to merge from.  This way these unnamed, "unmergeable"
temporaries are properly streamed by value again.

PR c++/114856

gcc/cp/ChangeLog:

* call.cc (make_temporary_var_for_ref_to_temp): Set context for
temporaries with linkage.
* init.cc (create_temporary_var): Revert to only set context
when in a function decl.

gcc/testsuite/ChangeLog:

* g++.dg/modules/pr114856.h: New test.
* g++.dg/modules/pr114856_a.H: New test.
* g++.dg/modules/pr114856_b.C: New test.

[Bug c/114746] With FLT_EVAL_METHOD = 2, -fexcess-precision=fast reduces the precision of floating-point constants and floating-point constant expressions

[vincent-gcc at vinc17 dot net via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114746

--- Comment #7 from Vincent Lefèvre  ---
BTW, in /usr/include/math.h from the GNU libc 2.37:

# define M_PI   3.14159265358979323846  /* pi */

i.e. M_PI is defined with 21 digits in base 10, which corresponds to about 70
digits in base 2, thus with the apparent intent to be accurate in extended
precision (64 digits).

This is not really odd since it does fail with those compilers with -fchecking
(which is the default for the GCC trunk development). It also works with the
trunk (in this case) with -fno-checking .  Basically GCC has some internal
checks to make sure things internally are consistent but they are failing in
this case and you can turn them off/on at compile time.

> Do you (or others) have any thoughts about GitLab FOSS?

Dunno about the FOSS edition specifically, but I've used many review
tools in anger in the last 5 years: github, gitlab, gerrit, phabricator,
and a couple that ran in bugzilla ("MozReview", not sure if it had some
other name; and a second one that I think was nameless).

For the most part they are pretty similar, IMO, and just the gloss
differs.  I didn't like some aspects of phabricator but I no longer full
recall what.  Maybe its support for patch series was weaker.

For github/gitlab, I think it's probably nicer if you're also using
their bug tracker.  Those also seem totally fine by and large.  Nicer
than bugzilla in some ways (nicer / more responsive UI), worse in others
(searching is not as good).

[jorg.brown at gmail dot com via Gcc-bugs]

--- Comment #4 from Jorg Brown  ---
Oddly, if I move the reference to HelloWorld into a separate routine, it works
(you can comment out a() and ba() returns what it should, on gcc 15.0)

struct strt {
  const char *ptr = 
  char data = '\0';

  constexpr strt() {}
  constexpr strt(const strt &__str) {}
};
constexpr strt f() { return {}; }
constexpr strt HelloWorld = f();

// This works fine...
const strt () { return HelloWorld; }
const char *ba() { return b().ptr; }

// This causes the verify_gimple failure, on gcc 15
const char *a() { return HelloWorld.ptr; }

= - = - = - = - = - = - =

Also odd is that the above code (including a()) works fine on gcc 10.1 through
13.2.  As seen https://godbolt.org/z/z3qnosG37

This should address the majority of issues left from Rainer's report 
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112959 .  I pushed this 
for now.

Rainer, thank you very much for your report and all the details. I am 
sorry our documentation was not up-to-date.

It would be great could you have a look at what is in install.texi now and 
advise whether that covers things properly. And any suggestions on how to 
improve.

Gerald

[Bug c++/114915] New: Constrained auto deduction in specialized template scope

[sska1377 at gmail dot com via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114915

Bug ID: 114915
   Summary: Constrained auto deduction in specialized template
scope
   Product: gcc
   Version: 13.2.1
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: sska1377 at gmail dot com
  Target Milestone: ---

Here is a simple code that uses constrained auto deduction in a template
specialization scope. By removing the specialization, the code compiles
successfully. However, with the specialization, the code fails to compile, even
though both cases should be equivalent.

Code:
template
concept TheConcept = __is_same(T, int);

template
void f() {
  TheConcept auto x = 1;
}

/* Here is the problematic function, 
   by removing the specialization below, everything works */
template<>
void f() {
  TheConcept auto x = 1;
}

int main() {
  f();
  return 0;
}

Command: $ g++ report.cpp -std=c++20 -Wall -Wextra -save-temps

Expected: Compilation success
Actual:

report.cpp: In function ‘void f() [with T = int]’:
report.cpp:11:23: error: deduced initializer does not satisfy placeholder
constraints
   11 |   TheConcept auto x = 1;
  |   ^

A possible fix:

https://gcc.gnu.org/pipermail/gcc-patches/2024-May/650391.html

[PATCH] Fix auto deduction for template specialization scopes [114915].

[Seyed Sajad Kahani]

When deducing auto for `adc_return_type`, `adc_variable_type`, and 
`adc_decomp_type` contexts (at the usage time), we try to resolve the outermost 
template arguments to be used for satisfaction. This is done by one of the 
following, depending on the scope:

1. Checking the `DECL_TEMPLATE_INFO` of the current function scope and 
extracting DECL_TI_ARGS from it for function scope deductions (pt.cc:31236).
2. Checking the `DECL_TEMPLATE_INFO` of the declaration (alongside with other 
conditions) for non-function scope variable declaration deductions 
(decl.cc:8527).

Then, we do not retrieve the deeper layers of the template arguments; instead, 
we fill the missing levels with dummy levels (pt.cc:31260).

The problem (that is shown in PR114915) is that we do not consider the case 
where the deduction happens in a template specialization scope. In this case, 
the type is not dependent on the outermost template arguments (which are the 
specialization arguments). Yet, we still resolve the outermost template 
arguments, and then the number of layers in the template arguments exceeds the 
number of levels in the type. This causes the missing levels to be negative. 
This leads to the rejection of valid code and ICEs (like segfault) in the 
release mode. In the debug mode, it is possible to show as an assertion failure 
(when creating a tree_vec with a negative size).
The code that generates the issue is added to the test suite as 
`g++.dg/cpp2a/concepts-placeholder14.C`.

This patch fixes the issue by checking that the template usage, whose arguments 
are going to be used for satisfaction, is not a partial or explicit 
specialization (and therefore it is an implicit or explicit instantiation). 
This check is done in the two only places that affect the `outer_targs` for the 
mentioned contexts.

One might ask why this is not implemented as a simple `missing_level > 0` 
check. The reason is that the recovery from the negative `missing_levels` will 
not be easy, and it is not clear how to recover from it. Therefore, it is 
better to prevent it from happening.

[Bug middle-end/114913] "verify_gimple failed" due to addition of two constexpr strings

[pinskia at gcc dot gnu.org via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114913

--- Comment #3 from Andrew Pinski  ---
here is a C++11 testcase:
```
  struct strt {
char *_M_dataplus;
char _M_local_buf=0;
constexpr strt()
  : _M_dataplus(&_M_local_buf) {}
constexpr strt(const strt &__str)
  : _M_dataplus(&_M_local_buf) {}
  };
  constexpr  strt
  f() {
return {};
  }
constexpr strt HelloWorld = f();
const char *a() { return HelloWorld._M_dataplus; }
```

it was rejected before GCC 10 with the following error message:
```
:13:31: error: 'strt{(&.strt::_M_local_buf), '\000'}' is not
a constant expression
   13 | constexpr strt HelloWorld = f();
  |   ^

```

Maybe that will give an hint where the issue is ...

Hey Mark,

If I were to set this up today, I would look at Authentik (which is what
I'm using for my personal services).  It is a bit simpler than Keycloak.
I would also certainly go for a container deployment of the service
instead, because (as you can see in the blog post) it's not trivial to
set things up in a correct manner.

Let me know if you need help with this!

Thanks,

[Bug analyzer/114914] New: False positive with -Wanalyzer-out-of-bounds

[udo at hypervisor dot org via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114914

Bug ID: 114914
   Summary: False positive with -Wanalyzer-out-of-bounds
   Product: gcc
   Version: 14.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: analyzer
  Assignee: dmalcolm at gcc dot gnu.org
  Reporter: udo at hypervisor dot org
  Target Milestone: ---

Created attachment 58079
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58079=edit
Test case

For the attached test case, the analyzer incorrectly flags an array overflow as
follows: test.c:7:9: note: valid subscripts for ‘c’ are ‘[0]’ to ‘[1]’

The analyzer doesn't grok that v is in range 253...254 in the else-branch of
x() and therefore n is in range 0...1 when f() is called.

Reproducer: https://godbolt.org/z/fnxxns13x

The false positive occurs with gcc-14.1.0-RC-20240430.
The latest release (gcc-13.2) sees nothing wrong with this code.
I would therefore consider this a regression.

Hi Jeff,


It looks like this patch's gcc.target/riscv/round_64.c testcase doesn't 
pass when run with newlib.
So I expected this would ultimately end up being a case where certain 
builtins aren't enabled when we're using a newlib based C library and 
that's exactly what happens here.


Essentially all the "function_c99_misc" routines are disabled for 
simplifications.  So we're presented with this in forwprop:



__attribute__((noclone, noinline))
float convert_float_to_float_round (float N)
{
  double _1;
  double _2;
  float _4;

;;   basic block 2, loop depth 0, maybe hot
;;prev block 0, next block 1, flags: (NEW, VISITED)
;;pred:   ENTRY (FALLTHRU,EXECUTABLE)
  _1 = (double) N_3(D);
  _2 = round (_1);
  _4 = (float) _2;
  return _4;
;;succ:   EXIT j.c:12:10

}


The test relies on the optimizer to realize that's just roundf and 
convert it to:


__attribute__((noclone, noinline))
float convert_float_to_float_round (float N)
{
  float _6;

;;   basic block 2, loop depth 0, maybe hot
;;prev block 0, next block 1, flags: (NEW, VISITED)
;;pred:   ENTRY (FALLTHRU,EXECUTABLE)
  _6 = __builtin_roundf (N_3(D));
  return _6;
;;succ:   EXIT (EXECUTABLE) z.c:12:10

}


Failure to do that conversion will result in different code generation 
in the end and thus all those scan-asm failures.  Thankfully we have a 
preexisting way to deal with this in the testsuite.






It also introduced:

FAIL: gcc.target/riscv/rvv/autovec/unop/math-nearbyint-run-2.c execution 
test


on rv32gcv newlib/linux.
I'll have to look at this next, but it could well end up being the same 
issue under the hood.

We tried it and gdb and then abandoned it.  We tried to integrate it
into the traditional gdb development style, having it send email to
gdb-patches.  I found these somewhat hard to read and in the end we
agreed not to use it.

I've come around again to thinking we should probably abandon email
instead.  For me the main benefit is that gerrit has patch tracking,
unlike our current system, where losing patches is fairly routine.

It essentially has to be mandated, IMO.

For GCC this seems somewhat harder since the community is larger, so
there's more people to convince.
I tend to think it's the principal reviewers that will drive this.  If 
several of the key folks indicated they were going to use system XYZ, 
whatever it is, that would drive everyone to that system.


We're currently using patchwork to track patches tagged with RISC-V.  
We don't do much review with patchwork.  In that model patchwork 
ultimately just adds overhead as I'm constantly trying to figure out 
what patches have been integrated vs what are still outstanding.


Patchwork definitely isn't the answer IMHO.  Nor is gitlab MRs which 
we use heavily internally.  But boy I want to get away from email and 
to a pull request kind of flow.


Do you (or others) have any thoughts about GitLab FOSS?
I would assume its basically the same as gitlab, except with any 
proprietary removed and that new features land in the enterprise version 
first and presumably migrate to the FOSS version over time.



What works well?  If you've wired up some CI bits, it's is extremely 
useful to test an under development patch.  Develop, push a branch, 
raise an MR.  At that point the CI system kicks in.  Subsequent pushes 
to the branch trigger fresh CI runs.  This aspect I really like and if 
you were to see internal flows, you'd see dev branches churning as a 
patch gets iterated on.  It also has features like "when this passes CI, 
automatically commit it", which we often use on the final patch 
iteration if there was a nit of some kind.





What doesn't?   Finding things in gitlab is *awful*.  Now we're just 
talking about one repo, so it may be more manageable in that regard. 
And we're not talking about using it for bug tracking.  As long as we 
kept on top of the MR queue, maybe it would be feasible.


So maybe I should soften my stance on gitlab.  If we're not using it for 
bug tracking and hosting many projects, then maybe its viable.


I think the driving force will be whether or not folks like you, Richi 
and others that do a ton of patch review would be more efficient in a 
gui or not.  I don't think I am, but maybe that would change if I did it 
every day for decades like I did with email :-)

The gitlab "community edition" still feels not very much "community".
We could run our own instance, but it will still be "open core" with
features missing to try to draw you towards the proprietary hosted
saas version. Also it seems to have way too much overhead. The focus
is clearly corporate developers where managers want assurances the
mandatory "pipelines" are executed and "workflows" followed exactly.

For now I am cleaning up Sergio's gerrit setup and upgrading it to the
latest version, so people can at least try it out. Although I must
admit that I seem to be the only Sourcewware PLC member that believes
this is very useful use of our resources. Even the biggest proponents
of gerrit seem to believe no project will actually adopt it. And on
irc there were some people really critical of the effort. It seems you
either love or really hate gerrit...

But the part that interests me most is the self-registration part that
Sergio setup. I believe we will need that for whatever system we end
up with to make it as easy to contribute as it is with email.
https://blog.sergiodj.net/posts/installing-gerrit-and-keycloak/

My personal favorite, if we really want a full "forge" would be
sourcehut. We already have mirrors of all projects at
https://sr.ht/~sourceware/ and there is a kind of sample "workflow"
(turning a "pull request" into an email thread) at
https://gnu.wildebeest.org/~mark/fsf-sourceware/presentation.html#slide18

At the moment though the only thing people seem to agree on is that
any system will be based on git. So the plan for now is to first setup
a larger git(olite) system so that every contributor (also those who
don't currently have commit access) can easily "post" their git
repo. This can then hopefully integrate with the systems we already
have setup (triggering builder CI, flag/match with patchwork/emails,
etc.) or any future "pull request" like system.

Cheers,

Mark

IMO, asking to always post the committed version as is (effectively
preventing doing "pushed with those nits fixed", or solving trivial
merge conflicts just before pushing) just to make patchwork happy would
be annoying and an additional burden, and noise on the mailing list.

The Change-Id trailer works very well for Gerrit: once you have the hook
installed you basically never have to think about it again, and Gerrit
is able to track patch versions perfectly accurately.  A while ago, I
asked patchwork developers if they would be open to support something
like that to track patches, and they said they wouldn't be against it
(provided it's not mandatory) [1].  But somebody would have to implement
it.

OK for trunk/13?  This isn't a very satisfactory fix, but at
least
it safely fixes these testcases I guess.  Note that there's
implementation disagreement about the second testcase, GCC
always
accepted it but Clang/MSVC/icc reject it.


Because of trying to initialize int& from {c}; removing the
extra
braces
makes it work everywhore.

https://eel.is/c++draft/dcl.init#list-3.10 says that we always
generate a
prvalue in this case, so perhaps we shouldn't recalculate if the
initializer is an init-list?


...but it seems bad to silently bind a const int& to a prvalue
instead
of
directly to the reference returned by the operator, as clang does
if
we add
const to the second testcase, so I think there's a defect in the
standard
here.


Perhaps bullet 3.9 should change to "...its referenced type is
reference-related to E or scalar, ..."


Maybe for now also disable the maybe_valid heuristics in the case
of
an
init-list?


The first testcase is special because it's a C-style cast; seems
like the
maybe_valid = false heuristics should be disabled if c_cast_p.


Thanks a lot for the pointers.  IIUC c_cast_p and
LOOKUP_SHORTCUT_BAD_CONVS
should already be mutually exclusive, since the latter is set only
when
computing argument conversions, so it shouldn't be necessary to check
c_cast_p.

I suppose we could disable the heuristic for init-lists, but after
some
digging I noticed that the heuristics were originally in same spot
they
are now until r5-601-gd02f620dc0bb3b moved them to get checked after
the recursive recalculation case in reference_binding, returning a bad
conversion instead of NULL.  (Then in r13-1755-g68f37670eff0b872 I
moved
them back; IIRC that's why I felt confident that moving the checks was
safe.)
Thus we didn't always accept the second testcase, we only started
doing so
in
GCC 5: https://godbolt.org/z/6nsEW14fh (sorry for missing this and
saying
we
always accepted it)

And indeed the current order of checks seems consistent with that of
[dcl.init.ref]/5.  So I wonder if we don't instead want to "complete"
the NULL-to-bad-conversion adjustment in r5-601-gd02f620dc0bb3b and
do:

Oops, that should be |= not =.


Perhaps bullet 3.9 should change to "...its referenced type is

conv = merge_conversion_sequences (t, new_second);
-   gcc_assert (maybe_valid_p || conv->bad_p);

This'd mean we'd go back to rejecting the second testcase (only the
call, not the direct-init, interestingly enough), but that seems to be


In the second testcase, with the above fix initialize_reference silently
returns error_mark_node for the direct-init without issuing a
diagnostic, because in the error path convert_like doesn't find anything
wrong with the bad conversion.  So more changes need to be made if we
want to set bad_p in the recursive case of reference_binding it seems;
dunno if that's the path we want to go down?

On the other hand, disabling the badness checks in certain cases seems
to be undesirable as well, since AFAICT their current position is
consistent with [dcl.init.ref]/5?

So I wonder if we should just go with the safest thing at this stage,
which would be the original patch that removes the problematic assert?


I still think the assert is correct, and the problem is that maybe_valid_p
is
wrong; these cases turn out to be valid, so maybe_valid_p should be true.


I'm afraid then I don't know how we can statically identify these cases
without actually performing the conversion, in light of the recursion :/
Do you mind taking this PR?  I don't feel well-versed enough with the
reference binding rules to tackle this adequately..


That ended up being a surprisingly deep dive, but I've now checked in separate
fixes for the two cases.


Very interesting, thanks a lot.

We represent a reference binding where the referent type is more qualified
