No it isn't. I made a comment related to that other PR, but IIRC the main point
here is that the function is not pulled out of the loop, which is independent
of how memcmp gets expanded.

Bug ID: 66392
   Summary: rejects-valid: copy-initialization through
user-defined conversion sequence fails
   Product: gcc
   Version: 5.1.0
Status: UNCONFIRMED
  Keywords: rejects-valid

testcase.cpp - inaccurately rejected

There are many variants of the supplied testcase, but the following shall
compile due to the wording of `[dcl.init]p17` (and relevant sections) - `gcc`
inaccurately rejects the snippet:

struct B { };

struct A { 
  explicit A (A const&);
   A (B const&);
};  

int main () {
  A x = B {}; // legal
}   

---

testcase.cpp: In function ‘int main()’:
testcase.cpp:9:12: error: no matching function for call to ‘A::A(A)’
   A x = B {}; // legal
^
testcase.cpp:5:12: note: candidate: A::A(const B&)
A (B const&);
^
testcase.cpp:5:12: note:   no known conversion for argument 1 from ‘A’ to
‘const B&’
testcase.cpp:5:12: note:   after user-defined conversion: A::A(const B&)

---

[ Note: `msvc`, `clang`, `icc` all accept the above snippet ]

---

In short the ISO C++ Standard says that if copy-initialization takes place
where the source type is not the same as the destination type, but there is a
user-defined conversion sequence that can convert the source type into the
destination type - such will be used to construct a temporary, and that
temporary will then be used to _direct-initialize_ the destination object.

It should be noted, as directly addressed in the standard wording, that
copy-elision may be used to skip the construction of the temporary object.

[ Note: it is important to note that the wording talks about "user-defined
conversion sequences", as such one must properly take into account usage of
`operator T`, where `T` is the destination type, in the source type which shall
yield the same described behavior as the attached testcase ]

--

Relevant part of `[dcl.init]p17`:

> Otherwise (i.e., for the remaining copy-initialization cases), user-defined
> conversion sequences that can convert from the source type to the destination
> type or (when a conversion function is used) to a derived class thereof are
> enumerated as described in [over.match.copy], and the best one is chosen

[Bug c++/53431] C++ preprocessor ignores #pragma GCC diagnostic

[manu at gcc dot gnu.org]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53431

--- Comment #10 from Manuel López-Ibáñez  ---
Created attachment 35688
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35688&action=edit
WIP patch

A WIP patch. I took a different approach: Move the handling of the pragma to
the preprocessor. 

It is a bit ugly, but the problem is that we cannot access diagnostic.h and
similar headers from the preprocessor. In my ideal world, we would have a
libdiagnostic.a that can be linked to the preprocessor and the FEs, and avoid
those callbacks (if someone wants to implement a different diagnostic output,
they can simply implement a basic libdiagnostic.a).

The main problem I didn't know how to solve is that, once processed, the
preprocessor removes the pragmas. Ideally, the pragmas should be evaluated when
lexing, independently of whether the file is preprocessed or not. Otherwise, it
will break things like ccache.

This is because the location of the warning is given at 21:19, which is not
within the range affected by the #pragmas. Whether the warning should be given
at the macro definition point or at the expansion point is a matter of debate
(there are at least two PRs open about this, but I don't remember the numbers).

Differences between C and C++ are spurious and may lead to the pragmas applying
or not:

cc1:
/home/manuel/test2/pr66099.cc:21:3: error: assuming signed overflow does not
occur when assuming that (X + c) < X is always false [-Werror=strict-overflow]
   TESTING(i + 4 < i);
   ^

occur when assuming that (X + c) < X is always false [-Werror=strict-overflow]
   TESTING(i + 4 < i);
   ^

Someone would need to track the locations in GDB and understand why they
diverge. Unfortunately, this is not something that usual devs will spend time
on given the amount of other things waiting to be fixed. If this is important
to you, I would recommend to try to figure out the reason yourself. Once the
problem is clear, it is far more likely that a GCC dev will produce a patch and
fix it.

Ah, right.  If it fixes the problem, then I think it's the only option we have
for the release branch.

[Bug rtl-optimization/66393] New: register asm input for inline asm not respected when using a template

In the following example r1 is being used as input to the inline asm although
the register asm definition forces it into r2:

typedef unsigned long long int uint64_t;

bar (T c)
{
  int a;
  register uint64_t b __asm__ ("r2") = (uint64_t)&a;

[Bug go/66303] runtime.Caller() returns infinitely deep stack frames on s390x

[vogt at linux dot vnet.ibm.com]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66303

--- Comment #9 from Dominik Vogt  ---
The problem is reproduceable with the makecontext C testcases in Glibc (with
some manual intervention).  So, this isn't a Go related problem.  Our analysis
so far seems to indicate that it's a bug in the s390x specific code of Glibc or
maybe the s390x unwinding code in libgcc (less likely).  We'll take care of the
problem.

testcase, warns with gcc-6 -c -O2 -fsanitize=undefined

The attached testcase derived from a C++ iterator implementation relies on the
fact that the undefined pCurrent-1 is immediately nullified again by the
following pCurrent++ by the optimizer. But in current trunk r224064 the
following warning is issued:

test.c: In function 'test':
test.c:19:53: warning: array subscript is below array bounds [-Warray-bounds]
 ths->pCurrent = (ths->pStart) ? ths->pStart - 1 : (stru *) 0;
 ^

Though the warning is not completely wrong, -Warray-bounds usually triggers
only when the value is really accessed, or? gcc-5.1 compiles the testcase
without warning.

testcase, warns with gcc-6 -c -O2 -fsanitize=undefined

Except it is undefined behavior to have one element before the start of an
array. And that is why it is warning. Does not matter if there is a ++ later
on.

Yeah, I feared so :-(. This is a bit unfortunate though, as for our code base
we compile with -Werror=array-bounds, now when I add -fsanitize=undefined I
need to downgrade the error to a warning again. Another special casing in the
build system... From this POV I would prefer to get only the
-fsanitize=undefined runtime error.

[Bug go/66368] [5 Regression] go tool crashes on powerpc-linux-gnu

--- Comment #6 from boger at us dot ibm.com ---
I think you've said the problem only occurs when using -fstack-protector-strong
and when building with glibc-2.21.

Have you tried using gdb to see where the segv actually occurs?

>gdb go
.


>run version
(Once it hits the segv)
>x/20ni $pc-24
>bt

The panic stacktrace is showing a line in proc.c:2328 which is making a call to
__builtin_return_address according to my source.  Does that match your source?

If that is the case then I have a feeling this isn't go specific, but a problem
with calling __builtin_return_address on ppc32 when using
-fstack-protector-strong and possibly glibc-2.21 has some affect.

--- Comment #10 from Dominik Vogt  ---
Just a short update before the bank holiday weekend in Germany.  The problem is
caused by missing cfi directives in the Glibc sources.  We'll open a Glibc bug
report and provide a patch next week.

Gdb has some safety checks in its unwinding code to catch such pathological
situations.  It might be worthwhile to add something similar to the unwinding
code in libgcc.

Reduced test case:

$ cat color.ii
template  void CvtColorLoop(int, int, const Cvt &);
enum { R2Y, G2Y, B2Y };
struct RGB2Gray {
  RGB2Gray(int, int, int coeffs) {
const int coeffs0[]{G2Y, B2Y};
coeffs = coeffs0;
tab[2] = coeffs;
  }
  int tab[];
};

cvtColor_bidx() {
  int src, dst;
  CvtColorLoop(src, dst, RGB2Gray(0, cvtColor_bidx, 0));
}

$ g++ -fmerge-all-constants -flto -c color.ii -c -fpermissive
