[Bug c++/107897] [13 Regression] ICE in verify_curr_properties, at passes.cc:2201

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

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107897

--- Comment #1 from Richard Biener  ---
(gdb) p fn->curr_properties
$4 = 92431

that looks like garbage.  We likely cut off processing one of the functions
because of the error (and failed to initialize ->curr_properties when
allocating struct function).  In particular we gate off build_ssa_passes
but not consistently all other small IPA passes and target_clone is the
only one requiring any SSA/CFG properties.

I'm testing a patch for the ICE-after-error, the error remains.

[Bug c++/107906] New: Function template specialization given weak rather than local symbol

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107906

Bug ID: 107906
   Summary: Function template specialization given weak rather
than local symbol
   Product: gcc
   Version: 13.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: herring at lanl dot gov
  Target Milestone: ---

Current trunk, given 

  template using X=int;
  namespace {
template using Y=int;
  }

  template class Q> void f() {}
  template void f();

  void (*fp)()=f;

emits weak symbols for both specializations of f, despite the fact that a
different "void f<(anonymous namespace)::Y>()" might be defined in another
translation unit (perhaps as an explicit specialization).

I notice there's TARGET_PROMOTE_PROTOTYPES which can prevent unsigend char 255
be extended to int 255 which is a more perfect solution to this problem. But we
can only get fntype in this hook, ideally we should check fndecl to make sure
it's target specific builtins since we don't want to prevent promotion for args
in other normal functions.

Same here, yet, the results prove that not only on Zen2, on top of that on
i5-7200U @2.5GHz and Windows 10, this function takes 203s, cannot figure it
out, could you run the wildtest_GCC executable (or compile to it) and see it is
so?

I think it is but it is a bit more complex though because we did try to
implement that Defect report, see bug 70353 comment #11.
Jason made the change to fix GCC to do what CWG 1962 says and then that had to
be reverted because it broken stuff so it was decided to go back to how GCC did
it.

I looked at the code generation and there is not much difference between GCC
and LLVM really.

The only difference I see some register allocation difference when it comes to
mask and name. GCC uses two extra registers to store those.

I don't see that causing a 2x slow down though.

  Severity: normal

The following code is accepted by gcc from 4.7 to 12:

Godbolt link: https://godbolt.org/z/EYqh1f3oa

#include 

void f()
{
using T = decltype(__func__);
T x = __func__;
static_assert(std::is_lvalue_reference::value, ""); // incorrectly
passes
// static_assert(std::is_array::value, ""); // incorrectly fails
}

It seems that gcc only treats __func__ as "an lvalue denoting an array object",
but not exactly "the array variable itself" specified in
[dcl.fct.def.general]/8.

Given there is an unresolved CWG issue 1962, this is possibly not a bug at this
moment. But it's unclear to me whether this is an intentional design.

[Bug target/106773] libbpf: failed to find BTF info for global/extern symbol 'bpf_link_fops'

[david.faust at oracle dot com via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106773

--- Comment #3 from David Faust  ---
There are two remaining issues:

1. We are missing support for 'linkage=extern' encoding for variables,
   so 'bpf_link_fops' and others are incorrectly marked with 'linkage=global'
   instead.

2. 'bpf_link_fops' variable is encoded as 'void' type not 'const void'.
   This is a result of the BTF being generated from internal DWARF
   representation. The distinction seems to be intentionally removed in
   dwarf2out.cc:add_type_attribute(), with the later side-effect that
   looking up the type DIE for the variable when generating BTF actually
   fails and falls back to the default 'void'.

I have an implementation for (1) in progress. For (2) I need to understand
why the 'void'/'const void' distinction is removed in DWARF and how to work 
around it.

[Bug libstdc++/107850] [12 Regression] std::erase_if (map) forces predicate to takes a const value_type

[chgros at synopsys dot com via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107850

--- Comment #4 from Charles-Henri Gros  ---
Looking into it further, there may be an implicit requirement that the
predicate does not modify its argument.
https://eel.is/c++draft/algorithms.requirements#6
"When not otherwise constrained, the Predicate parameter is used whenever an
algorithm expects a function object ([function.objects]) that, when applied to
the result of dereferencing the corresponding iterator, returns a value
testable as true.
In other words, if an algorithm takes Predicate pred as its argument and first
as its iterator argument with value type T, it should work correctly in the
construct pred(*first) contextually converted to bool ([conv]).
The function object pred shall not apply any non-constant function through the
dereferenced iterator.
Given a glvalue u of type (possibly const) T that designates the same object as
*first, pred(u) shall be a valid expression that is equal to pred(*first)."
I'm unfortunately not well-versed enough in C++ legalese to tell what "possibly
const" means in that context, nor "apply any non-constant function".
And while I understand that a "predicate" is generally meant to not do
modification, there are fairly frequent use cases for "apply this potentially
modifying operation, and depending on its result remove the element from the
container". And in practice, this works (e.g. std::remove_if, your own earlier
version of erase_if, other compilers' version...).
Maybe I should go to LEWG and lobby to remove that limitation. In the
meanwhile, I'll probably just keep my own, perhaps slightly less optimal
removal algorithms.
