Note that this report response does not say that the translation
unit must also be successfully linked, in a hosted implementation, to
produce a program.

A mismatch, in linkage, can only occur when a reference is of a
different type from the definition.

In this translation unit alone, there is no type mismatch, because
the unit contains only a reference to printf, and no definition.

The translation unit can be part of a program where it makes sense.
E.g. in a freestanding implementation, where there isn't a library
with a printf, another translation unit can supply a compatible
definition of printf. Then, if (0) can be flipped to if (1) and
checkup() can be called, even.

There is no type problem here whatsoever that is comparable to
an operator being given operands whose type combination is not
defined for the operator. That's a problem entirely confined in
translation phase 7; it cannot be rescued by adding a suitable
secondary translation unit.

A call to an implicitly declared printf is translatable. There are
requirements about every aspect of it. There are no requiremnts
about how to translate (void *)

It requires a tag though as WG14 did not want to allow this for anonymous
structs.

Thanks for the comments, do you mean it can affect the arguments validation 
when there
is explicit function declaration with interface?  Then can we strip them when 
we are
going to expand them (like checking currently_expanding_function_start)?  since 
from the
perspective of resulted assembly, with this workaround, the callee can:
  1) pass the hidden args in unexpected GPR like r11, ... at -O0;
  2) get rid of such hidden args as they are unused at -O2;
This proposal aims to make the assembly at -O0 not to pass with r11... (same as 
-O2),
comparing to the assembly at O2, the mismatch isn't actually changed.

BR,
Kewen

```
  /* ~A + A -> -1 */
  (simplify
   (plus:c (convert? (bit_not @0)) (convert? @0))
   (if (!TYPE_OVERFLOW_TRAPS (type))
(convert { build_all_ones_cst (TREE_TYPE (@0)); })))

  /* ~A + 1 -> -A */
  (simplify
   (plus (convert? (bit_not @0)) integer_each_onep)
   (if (tree_nop_conversion_p (type, TREE_TYPE (@0)))
(negate (convert @0

  /* -A - 1 -> ~A */
  (simplify
   (minus (convert? (negate @0)) integer_each_onep)
   (if (!TYPE_OVERFLOW_TRAPS (type)
&& TREE_CODE (type) != COMPLEX_TYPE
&& tree_nop_conversion_p (type, TREE_TYPE (@0)))
(bit_not (convert @0

  /* -1 - A -> ~A */
  (simplify
   (minus integer_all_onesp @0)
   (if (TREE_CODE (type) != COMPLEX_TYPE)
(bit_not @0)))

```

I am not sure which one of these patterns need the check for
TYPE_OVERFLOW_SANITIZED though.

Note you can remove continue/[[unlikely]]` and reproduce it with `-O3
-fdisable-tree-lim2`.

Also note disabling VRP2, `-fdisable-tree-vrp2` allows the code to pass which
gets me the feeling like maybe lsplit is not rewriting the check to be overflow
safe.

  Hi, I have test this patch and it is very good. I think we need to add some
runable tests to ensure that the results are right for various types of
conversions, operations, and libfuncs.


Sorry I forgot to reply earlier, a few of us were talking about this is 
the patchwork meeting this morning.  We think this is too big for GCC-14 
this late in the cycle.  Folks are still looking at bugs, so it might 
take a bit to get reviewed for GCC-15.


I took a look and don't see anything wrong, but I'm not a floating-point 
person so I'd want to try and talk to someone who is before committing 
it.


More testing never hurts, though ;)

Modified extended test case

I modified the extended test case so I could review this and summarize.
Currently this is what we get with my comments at the end of each line. I
marked some that I think are clearly incorrect.  Maybe OK depends on on
strictly one chooses to interpret what the standard says.  If we assume that
one or more spaces is an acceptable separator if followed by a non-value I
indicate those with the word space.

  Hi, I have test this patch and it is very good. I think we need to add some
runable tests to ensure that the results are right for various types of
conversions, operations, and libfuncs.

BR,
Jin

After g:b8e7aaaf350a4584d9b76e8dd69daa2203bac339, r14-9706-gb8e7aaaf350a45 we
have noticed a regression on our "thumb_m3_eabi" and "thumb_m55_hard_eabi"
(more details about them later):

I selected "testsuite" as the problematic component because the commit above
only made testsuite changes, but I'm not sure if this is a symptom of a problem
somewhere else.

In the "thumb_m3_eabi" configuration, GCC was configured with:

[Bug c++/107945] static constexpr incomplete (depedent) data member of a class template and in-member initialized incorrectly accepted

--- Comment #5 from Brian Bi  ---
In the first case, I think GCC's behaviour can be argued to be correct.
[temp.inst]/3.1 says that when you implicitly instantiate a class template, you
only instantiate the declarations of static data members, not their
definitions. Which means that until you do something that provokes the
instantiation of the *definition* of `C::t`, the compiler must
treat it as a variable of type `const incomplete` that is
declared-but-not-defined, which means that you haven't yet actually attempted
to define a variable with incomplete type, which means the program is
well-formed.

In the most recent example given by Jason Liam we can reduce it to:

template 
struct S {
constexpr static S s = {};
};
int main() {
auto s = S::s;
}

This may be related to bug 70820, which was closed as INVALID. I think perhaps
that decision should be revisited; while I can see the argument for the above
code being well-formed, I think the interpretation of the standard being taken
in this case is wrong.

Right, of course.  How about this?
Bootstrapped and regtested on x86_64-pc-linux-gnu, OK for trunk?

-- >8 --

A template instantiation still needs to have its DECL_SAVED_TREE so that
its definition is emitted into the CMI. This way it can be emitted in
the object file of any importers that use it, in case it doesn't end up
getting emitted in this TU.

gcc/cp/ChangeLog:

* semantics.cc (expand_or_defer_fn_1): Keep DECL_SAVED_TREE for
all vague linkage functions.

gcc/testsuite/ChangeLog:

* g++.dg/modules/pr104040_a.C: New test.
* g++.dg/modules/pr104040_b.C: New test.

I am not getting an ICE here. Until sub is defined or further definitions on
components to t or t2, I do not see a basis to reject anything or give a

without the align:

Inserting a partition copy on edge BB2->BB3 : PART.0 = PART.3
Inserting a value copy on edge BB2->BB3 : PART.1 = 2048


vs with:

Inserting a partition copy on edge BB3->BB3 : PART.7 = PART.0
Inserting a partition copy on edge BB2->BB3 : PART.7 = PART.3
Inserting a value copy on edge BB2->BB3 : PART.1 = 2048


Basically out of ssa is doing an extra move because it could not "merge" the
loop induction variable for the (vector) addition due to the different
alignment requirements ... 

And then things go down hill from there.

This cuts a lot deeper than folks think. Here are two other examples
off the top of my head...

Other vulnerable projects include ncurses and libnettle. Ncurses is
run by Thomas Dickey (https://invisible-island.net/). libnettle is run
by Niels Möller (https://www.lysator.liu.se/~nisse/nettle/). Both are
one-man shows with no continuity plans. Dickey does not even run a
public version control system. You have to download his release
tarballs, and there's no history to review or make pull requests
against. If DIckey or Möller got hit by a bus crossing the street,
there would be problems for years.

--- Comment #2 from Andrew Pinski  ---
Note the original testcase worked in GCC 8.5.0 and before and the reduced
testcase with the C++ front-end too. Due to not creating MIN/MAX expression
early.
So I am going to make this as a regression because the user would not
understand the difference really.

--- Comment #1 from Andrew Pinski  ---
Confirmed. Reduced testcase without the need of inlining nor atomics:
```
int g(int);
int h(int);

int f(int a, int b)
{
  while (true)
   {
  int t = a < b ? a : b; // MIN
  if (b <= a)
return a; 
  { a = g(a); if (h(t)) return t; }
// t here should be old a before the assignment from `g(a);`
   }
}
```

As far as I can tell this is basically slightly more complex version of PR
110199 really wehre the MIN (MAX) has 2 usages. Note if we the usage of t in
`h(t)` the trunk (due to  PR 110199) is able to optimize it correctly to
`return a`.

Also since you are using a redhat provided compiler you should be reporting it
to them.

[Bug tree-optimization/114551] [14 Regression] wrong code at -O3 on x86_64-linux-gnu since r14-2944

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

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114551

--- Comment #3 from Andrew Pinski  ---
The first major difference with/without continue is the moving of `f >
(2147483647 - a)` checkout of the loop via lim2 in the case of not having the
continue.

You can replace the inner most loop with:
```
for (; c < 4; c++) {
  [[unlikely]];
  d = f && a > 0 && f > (2147483647 - a) ? 0 : b[f];
}
```

Also so yes it is the continue predictor that is coming into play.

I agree that GDB, and for that matter other projects with significant numbers 
of contributors, are not nearly as likely to be vulnerable to this sort of 
attack.  But I worry that xz may not be the only project that's small enough to 
be vulnerable, and be security-relevant in not so obvious ways.

One question that comes to mind is whether there has been an effort across the 
open source community to identify possible other targets of such attacks.  
Contributions elsewhere by the suspect in this case are an obvious concern, but 
similar scenarios with different names could also be.  That probably should be 
an ongoing activity: whenever some external component is used, it would be 
worth knowing how it is maintained, and how many eyeballs are involved.  Even 
if this isn't done by everyone, it seems like a proper precaution for security 
sensitive projects.

Another question that comes to mind: I would guess that relevant law 
enforcement agencies are already looking into this, but it would seem 
appropriate for those closest to the attacked software to reach out explicitly 
and assist in any criminal investigations.

PR modula2/114565 progress trace would be useful to isolate ICE for users

This patch introduces the internal option -fm2-debug-trace= which can
be given a comma separated list of filter terms.  Currently it allows:
all,line,token,quad.  The patch allows users to trace the progress of
cc1gm2 so that source which causes an ICE can be reduced.  Once
PR113836 is complete it is expected that the trace information will be
written to file.

I think we can just disable icf1 on darwin, and not try to merge i and j.

It would be nice for icf[23] to work, since those don't involve
externally-visible symbols (or even names at all).  It would be good to
understand what is preventing the optimization in that case.

here is the latest link:

So reading the page, it is only can be used when AVX512 is enabled now.

Before back in 2012 it was just for IA64 and then MiC was added and both have
been removed the documentation (as both are long gone).

I think that is working we end up with two constant text arrays (no copy via
automatic storage as mentioned in the paper)

Actually, the optimisation is failing on Darwin - we produce two distinct
arrays.

(although, if it succeeds then technically that's breaking the ABI since we
then have two external symbols with the same addresss).

SO I suppose the question is do we want to figure out why the opt is failing
(knowing that if it succeeds that is a secondary issue) - or just
dg-xfail-run-if for Darwin?

This is what we generate now:
.const
.align 3
_i:
.long   1
.long   2
.long   3
.globl _j
.align 3
_j:
.long   1
.long   2
.long   3

and we do access i and j directly (i.e. not via the GOT).

Re: AutoFDO tools for GCC

[Snehasish Kumar via Gcc]

Thanks for initiating this discussion Eugene. For a little bit more context
on the motivation -- Meta has developed a new type of AutoFDO which is
committed upstream in LLVM and we want to unify our tooling with this
approach.

> I do wonder how much common code there is
> between the LLVM and the GCC tooling though and whether it makes sense
> to keep it common (and working with both frontends)?

The key components are the perf.data reader, profile construction data
structures and the profile writer. The reader parses perf.data as protobuf
[1] and suffers from a few drawbacks (as Andi pointed out). The
intermediate data structure which represents the profile is shared
(~1500LOC in [2]). Finally, LLVM and GCC have their own bespoke profile
writers [3]. So given the drawbacks of reader and limited sharing I think
it would be best to fork these tools into the GCC repo. Having perf
generate the profiles is an interesting idea and in addition to addressing
the issues Andi raised, would also simplify replicated symbolization logic.
In fact, the new implementation in LLVM parses perf script output [4] to
generate AutoFDO profiles. Finally, if AutoFDO is adopted by the kernel, a
dependence on another repository is undesirable.

Yes, this should be straight-forward.

I can ask around more on my end if I get clarification on this.

Thanks,
Snehasish

Confirmed.

in fold_offsetof, we still have:
```
case COMPONENT_REF:
...
  off = size_binop_loc (input_location, PLUS_EXPR, DECL_FIELD_OFFSET (t),
size_int (tree_to_uhwi (DECL_FIELD_BIT_OFFSET (t))
  / BITS_PER_UNIT));

```

and:
```
case ARRAY_REF:
...
  off = size_binop (MULT_EXPR, TYPE_SIZE_UNIT (TREE_TYPE (expr)), t);
```

Ugh.  I forgot literal constants don't have symtrees or names. :(

Re: Sourceware mitigating and preventing the next xz-backdoor

A big thanks to everybody working this long Easter weekend who helped

This email isn't about the xz-backdoor itself. Do see Sam James FAQ
https://gist.github.com/thesamesam/223949d5a074ebc3dce9ee78baad9e27
(Sorry for the github link, but this one does seem viewable without
proprietary javascript)

We should discuss what we have been doing and should do more to
mitigate and prevent the next xz-backdoor. There are a couple of
Sourceware services that can help with that.

TLDR;
- Replicatable isolated container/VMs are nice, we want more.
- autoregen buildbots, it should be transparent (and automated) how to
   regenerate build/source files.
- Automate (snapshot) releases tarballs.
- Reproducible releases (from git).

[snip]


While I appreciate the effort to harden the Sourceware infrastructure 
against malicious attacks and want to join in on thanking everyone who 
helped analyze this issue, to me it seems like the much bigger problem 
is that XZ had a maintainer who appears to have acted in bad faith.  
Are the development processes used by the GNU toolchain components 
robust enough to cope with deliberate sabotage of the code base?  Do 
we have enough eyes available to ensure that every commit, even those 
by designated maintainers, is vetted by someone else?  Do we to harden 
our process, too, to require all patches to be signed off by someone 
else before committing?


-Sandra


What likely happened for the maintainer who acted in bad faith was that 
they entered the project with bad faith intent from the start - seeing 
as they were only involved with the project for 2 years, and there was 
much social pressure from fake email accounts for the single maintainer 
of XZ to accept help.


While we would obviously like to have more area maintainers and possibly 
global maintainers to help spread the load, I don't think any of the 
projects listed here are all that susceptible to the same type of social 
engineering. For one, getting the same type of blanket approval would be 
a much more involved process because we already have a reasonable amount 
of people with those privileges, no one is dealing with burnout and 
sassy customers saying we aren't doing enough.


Beyond that, we (GDB) are already experimenting with approved-by, and I 
think glibc was doing the same. That guarantees at least a second set of 
eyes that analyzed and agreed with the patch, I don't think signed-off 
would add more than that tag (even if security was not the reason why we 
implemented them).

Though that doesn't involve the attribute, and promoting init-lists to static
should work fine on darwin.

It is a non-binding request. And yes, if this optimization is problematic on
darwin, we should adjust the test.

[Bug middle-end/41088] "TYPE_UNSIGNED (type) = 1;" in fixup_unsigned_type may be deleted

Andrew Pinski  changed:

   What|Removed |Added

 Resolution|--- |FIXED
   Target Milestone|--- |4.9.0
 Status|NEW |RESOLVED

--- Comment #2 from Andrew Pinski  ---
The opposite happened, that is the change for TYPE_UNSIGNED was removed from
layout_type by r0-125924-gc0e081a968c78d so I think we can close this as fixed.
