Patches have been posted, I'm waiting for Objective-C maintainers to (not)
object before committing.  The warnings you see are cured by the c-decl.c part:
the behavior of choosing int is correct, but the warning is superfluous (though
theoretically correct).

So compiling wine with -fomit-frame-pointer creates a broken wine?  Can you try
to find a small testcase.  Try first by bi-secting the object files.

[Bug c/46468] New: enabling -fomit-frame-pointer by default breaks Wine

[austinenglish at gmail dot com]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46468

   Summary: enabling -fomit-frame-pointer by default breaks Wine
   Product: gcc
   Version: 4.6.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: austinengl...@gmail.com


I've noticed lately that 'winetricks -q fm20' fails on my machine. I finally
got around to running an svn bisect:

=
Regression found!
Last good revision: r163193
First bad revision:

r163196 | hjl | 2010-08-12 09:39:37 -0700 (Thu, 12 Aug 2010) | 16 lines

Turn on -fomit-frame-pointer by default for 32bit Linux/x86.

2010-08-12  H.J. Lu  
Uros Bizjak  

* config.gcc: Handle --enable-frame-pointer.

* configure.ac: Add --enable-frame-pointer.
* configure: Regenerated.

* config/i386/i386.c (USE_IX86_FRAME_POINTER): Default to 0.
(override_options): If not configured with --enable-frame-pointer,
enable -fomit-frame-pointer (but not for TARGET_MACHO or when
optimizing for size), -fasynchronous-unwind-tables and
-maccumulate-outgoing-args by default.

=

so, I tried compiling wine with -fno-omit-frame-pointer, still fails. The only
way to get a working wine was to compile gcc with --enable-frame-pointer.

The wine failure isn't too helpful:
$ wine /home/austin/.wine/dosdevices/c:/winetrickstmp/setup /qt
wine client error:3b: write: Bad file descriptor
err:seh:raise_exception Unhandled exception code c005 flags 0 addr
0x7dd247be
wine client error:3b: write: Bad file descriptor

however, the bug seems to be gcc producing bad code unless
--enable-frame-pointer is used.

RTL constant propagation (cprop3) changes

(reg/f:DI 95 [ s ])) -1 (expr_list:REG_EQUAL (plus:DI (reg/v/f:DI 83 [

to

(reg/f:DI 95 [ s ])) -1 (expr_list:REG_EQUAL (const_int 2 [0x2])
(nil)))

note that the original REG_EQUAL note is suspicious anyway as it references
the set destination.  The note is correct though, reg:DI 95 is set as

(insn 11 3 12 2 t.c:5 (parallel [
(set (reg/f:DI 95 [ s ])
(plus:DI (reg/v/f:DI 83 [ s ])
(const_int 2 [0x2])))
(clobber (reg:CC 17 flags))
]) 253 {*adddi_1} (expr_list:REG_UNUSED (reg:CC 17 flags)
(nil)))

RTL PRE generates insn 75 and also adds this REG_EQUAL note.

Stopping here with my investigation.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46339

--- Comment #4 from Tobias Burnus  2010-11-13 
19:01:00 UTC ---
(In reply to comment #3)
> This avoids the segfault.  But what is lang_specific and why is it not set in
> problem case?  Where does it normally get set?

lang_specific allows to attach front-end specific data to a middle-end tree.
The lang-specific part can be obtained by using
  DECL_LANG_SPECIFIC (decl)
thus, your check should rather use
  DECL_LANG_SPECIFIC (expr1->symtree->n.sym->backend_decl)

See trans.h for the access macros for this data. In the given case, one uses
  GFC_DECL_SPAN (decl)
Thus searching for GFC_DECL_SPAN should show all files in which the value
should have been set.

If I recall correctly, it allows for
  pointer => dt(:)%element
which currently cannot be properly represented as on used a sm (stride
multiplier) of sizeof(dt) rather than a stride in bytes, thus a subpointer with
a span has been introduced. But I might also misremember.

Regarding the program:
  axis => p(:)%r%vec(1)
is what I have described. (I have added the "(:)" for clarity.) That's an array
to the the component "r%vec(1)" of all elements of the array "p".

Status: UNCONFIRMED
  Severity: normal

Compiling

  struct S { bool b; };
  constexpr S f() { return S{true}; }
  static_assert(f().b,  "");

with

  g++ -std=c++0x -fno-elide-constructors

results in

  t.cpp:3:26: internal compiler error: Segmentation fault
  Please submit a full bug report,

Omitting -fno-elide-constructors makes the problem go away.

I actually new about this, it's PR45062.

The Objective-C failures are bad.

The others are just tests that need to be adjusted, however for a couple of
them it's better to improve error recovery further.

[Bug other/46464] New: libiberty pointer size assumptions for Win64 incorrect

[nightstrike at gmail dot com]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46464

   Summary: libiberty pointer size assumptions for Win64 incorrect
   Product: gcc
   Version: unknown
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: nightstr...@gmail.com
Target: x86_64-*-mingw32


md5.h incorrectly assumes the size of a pointer to be a long int.  On Win64,
this isn't the case.  There was discussion and a proposed patch here:

http://gcc.gnu.org/ml/gcc-patches/2009-03/msg00638.html

And a ping here:

http://gcc.gnu.org/ml/gcc-patches/2009-09/msg01515.html

And then the issue died.

The proposed patch does an ifdef on _WIN64.  There may be a more elegant
solution, such as using a configure test to see if uintptr_t is defined, and to
use that.  I really don't know.  I just don't want the issue to slip away
untouched.

Also note that to the best of my knowledge, it appears that the issue has not
yet been addressed in the year and two months since that last ping.  If it has,
then I apologize for the bug report.

One more thing.  I couldn't find libiberty in the list of components to write
the bug against, so I wrote it against "other".

[Bug middle-end/46461] New: [4.6 Regression] ICE: invalid argument to gimple call at -O with __builtin_memset()

[zsojka at seznam dot cz]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46461

   Summary: [4.6 Regression] ICE: invalid argument to gimple call
at -O with __builtin_memset()
   Product: gcc
   Version: 4.6.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: middle-end
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: zso...@seznam.cz
  Host: x86_64-pc-linux-gnu
Target: x86_64-pc-linux-gnu


- testcase.c -
void
foo (char *c)
{
  c[7] = 0xff;
  __builtin_memset (c + 8, 0xff, 8);
}
--

Compiler output:
$ gcc -O testcase.c
testcase.c: In function 'foo':
testcase.c:6:1: error: invalid argument to gimple call
&MEM[(char *)c_1(D) + 7B]

Strangely, no regular ICE message i s given.

With -foptimize-sibling-calls, there is the message:
$ gcc -O -foptimize-sibling-calls testcase.c 
testcase.c: In function 'foo':
testcase.c:6:1: error: invalid argument to gimple call
&MEM[(char *)c_1(D) + 7B]
testcase.c:6:1: internal compiler error: in refs_may_alias_p_1, at
tree-ssa-alias.c:989
Please submit a full bug report,
with preprocessed source if appropriate.
