[Bug target/27829] New: ICE/abort in shift_op, at config/arm/arm.c:7917 with asm from testsuite/gcc.dg/pr21255-2-mb.c

2006-05-30 Thread flash at pobox dot com

Calling an ARM-targeted GCC 3.4.4 on the testsuite file gcc.dg/pr21255-2-mb.c
results in "internal compiler error: in shift_op, at config/arm/arm.c:7917".  

A slightly reduced version of the file is:

double d;
double
f (void)
{
  double r;
  asm ("mov %S1,%S0; mov %R1,%R0" : "=&r" (r) : "m" (d));
  return r;
}

The relevant source seems to be:

  if (GET_CODE (XEXP (op, 1)) == REG || GET_CODE (XEXP (op, 1)) == SUBREG)
*amountp = -1;
  else if (GET_CODE (XEXP (op, 1)) == CONST_INT)
*amountp = INTVAL (XEXP (op, 1));
  else
abort ();

CodeSourcery versions 3.4.4 (release) (CodeSourcery ARM 2005q3-2) and
2006q1/4.1.0 give a similar error.
x86 GCC 3.3.5 (Debian 1:3.3.5-8ubuntu2), and a checking=all build of 4.1.0
instead give an apparently reasonable rejection message: "error: invalid `asm':
invalid operand code `R'".



Here's the session; I'll attach the preprocessed source.

It does happen in CodeSourcery's version of 4.1.0 (which I've filed noted above
and with them).  I don't have access to an ARM-targeted 3.4.5, 3.4.6, 4.0.x,
nor a non-CodeSourcery 4.1.x.

[Bug other/27851] New: Hour-long segfault with -O1 -g on gcc.dg/parm-impl-decl-1.c

2006-05-31 Thread flash at pobox dot com

The code below causes a checking=yes build of GCC 4.1.1 to report "Internal
error: Segmentation fault (program cc1)" after more than an hour.  (Ninety
minutes in the session below; sixty-eight minutes the first time, on a faster
and less loaded machine.)  Likewise a checking=all build of GCC 4.1.0.  A
checking=all build of GCC 4.0.2 completes without error in a fifth of a second.

foo (int __attribute__ ((__mode__ (vector_size(8 i) /* { dg-warning
"warning: '__mode__' attribute ignored" } */
{
}
h (int (*p)[sizeof(i())])
{
}

The above code is Delta-reduced from the test suite file
gcc/testsuite/gcc.dg/parm-impl-decl-1.c.
This sounds reminiscent of bug 18239 or bug 16873, but those are supposedly
fixed.


Here are sessions; I'll attach the preprocessed file.

[Bug c++/27881] New: Memory exhausted with -finline-functions on testsuite file alias3.C

2006-06-02 Thread flash at pobox dot com

Compiling the GCC testsuite file alias3.C with -O1 -finline-functions exhausts
memory on checking=all or =yes builds of GCC 4.1.1, on Ubuntu 5.04 with virtual
memory limited to 500M.  Roughly similar behavior on Mac OSX 10.4.6 with a
checking=all build of GCC 4.1.0, though ulimit is broken on the Mac, so I had
to kill the process manually.  A checking=all build of GCC 4.0.2 compiles
without error.
The symptoms are similar to my PR26774, but that's fixed in 4.1.1, and
didn't require optimization.
Here's the Delta-reduced file:

namespace A{
  struct X{};
  void f(X&);
  namespace a_very_long_namespace_name{
  }
}
namespace B = A;
void B::f(A::X& x)
{
  B::f(x);
  f(x);
}

[Bug debug/24304] New: Test suite file 20010209-1.c with -g1 gives gen_subprogram_die, at dwarf2out.c:10857

2005-10-10 Thread flash at pobox dot com

Compiling the test suite file 20010209-1.c with -g1 gives "internal compiler
error: in gen_subprogram_die, at dwarf2out.c:10857".  This sounds a lot like
bug 16035, but the line number is different (10824 with my build), and that bug
requires -g -O, whereas this one requires -g1, and does not require
optimization.
Here's the session:

[Bug other/22320] New: -ftree-dominator-opts documentation is the same as -ftree-dce

2005-07-05 Thread flash at pobox dot com

The GCC 4.0.0 documentation, page 71 in the PostScript version, 
<http://gcc.gnu.org/onlinedocs/gcc-4.0.0/gcc/Optimize-Options.html#Optimize-Options>
in the HTML version, says the following:

-ftree-dce
Perform dead code elimination (DCE) on trees. This flag is enabled by default 
at -O and higher. 
-ftree-dominator-opts
Perform dead code elimination (DCE) on trees. This flag is enabled by default 
at -O and higher. 

Dominator options seem to be different from dead code, so presumably these are 
different.  
Alternatively, if they have the same behavior under different names, that 
should be noted explicitly, as 
it is elsewhere for such options.

[Bug c++/22508] New: Segmentation fault or EXC_BAD_ACCESS with modified Eckel sample code

2005-07-15 Thread flash at pobox dot com

The command below results in "internal compiler error: Segmentation fault" with 
the checking-
enabled version of GCC 4.0.1 on Suse Linux 9.2.  It also crashes with Apple GCC 
4.0.0 on Mac OSX 
10.4.2.  
GCC 3.3.4 on Suse rejects the code without crashing, as does CodeSourcery 
arm-none-linux-
gnueabi-g++ 3.4.3, our local version of arm-softfloat-linux-gnu 3.4.1, and (on 
OSX) Apple's GCC 3.3 
and my own build of 3.4.0.

/opt/gcc401chk/bin/g++ -c   ../cpp/bugfiles/error/EckelRob_104822.ii 

../jammed/Barney/eckel.cpp: In function std::string EckelCode::FramisTest():
../jammed/Barney/eckel.cpp:2039: internal compiler error: Segmentation fault

With the Apple version of GCC 4.0.0, it gives a crash dialog (with a 
Report button which doesn't 
work) with the following text:

The application cc1plus quit unexpectedly
EXC_BAD_ACCESS (0x1)
KERN_PROTECTION_FAILURE (0X2) at 0xc

Thread 0 Crashed:
0 0x1000 + 457016


I'll attach the preprocessed source.  It was copied by Rob Stevenson, a 
former PalmSource employee, 
from volume one of Bruce Eckel's _Thinking in C++_.  Here's the relevant 
function:

string FramisTest() {
stringstream ss2;
  Framis* f[Framis::psize];
  try {
for(int i = 0; i < Framis::psize; i++)
  f[i] = new Framis;
new Framis; // Out of memory
  } catch(bad_alloc) {
ss2 << "Out of memory!" << endl;
  }
  delete f[10];
  f[10] = 0;
  // Use released memory:
  Framis* x = new Framis;
  delete x;
  for(int j = 0; j < Framis::psize; j++){
ss2 << f[j]->ReturnStrStream() ;
delete f[j]; // Delete f[10] OK
   }
  return ss2.str() ;

Actual Result:
1

Expected Result:
Anything but 1 or 0.

For recursive crash testing, the return code for an internal compiler error 
should be distinguishable 
from that for correct rejection of incorrect code.  As a workaround, I've been 
checking the output for 
the presence and absence of various patterns, but this is inelegant and subject 
to error.

[Bug c++/22603] New: internal compiler error: in pop_binding, at cp/name-lookup.c:380

2005-07-21 Thread flash at pobox dot com

The invalid code below results in "internal compiler error: in pop_binding, at 
cp/name-lookup.c:380" 
with a checking version of GCC 4.0.1.  Does not happen with GCC 3.3.4.

class NameOne : public static_small_value
{
 inline NameOne(T v) {
 }
{
};
template
class NameTwo : private NameThree
{
void NameFour(const struct NameFive &cache);

This code is a greatly-reduced (and anonymized) excerpt, found by Daniel 
Wilkerson's Delta, from some 
real PalmSource code; I'm not sure it makes any sense at all.  The original 
code seemed to give a 
different compiler error, which I'll try to file separately; though it involves 
16K lines of proprietary code, 
so it may have to wait for our CodeSourcery support agreement.

[Bug c++/22604] New: "internal compiler error: Segmentation fault" with invalid nested classes

2005-07-21 Thread flash at pobox dot com

The invalid code below results in "internal compiler error: Segmentation fault" 
with a checking version of GCC 4.0.1.  Does not happen with GCC 3.3.4 or Apple 
GCC 4.0.0.
Like the code for bug 22603, this is a greatly-reduced and anonymized excerpt, 
found by Daniel 
Wilkerson's Delta, from a real PalmSource file.  (This reduction was found by 
looking for a segfault; the 
previous reduction looked for any compiler error.)  
I don't think this is the same bug as my 22508, since that one also 
happened with Apple GCC 4.0.0.  
It doesn't sound to me like 21975 or 22441 either.


class NameOne;
class NameTwo : virtual public SAtom
{
 virtual NameOne* NameThree();
};
class NameFour : virtual public NameFive
{
class NameOne : public NameTwo
{
  virtual NameOne* NameThree();

[Bug driver/22600] Exit code should be different from 1 for internal compiler error

2005-07-22 Thread flash at pobox dot com

Looking for a string pattern in the output leaves you vulnerable to 
correctly-rejected files which 
happen to generate that pattern in an error message.  That's probably less of 
an issue with GCC's hand-
crafted test code, but it was a real problem with the PalmSource compiler 
(which admittedly has more 
verbose error reporting) when doing random crash-testing.  Our compiler prints 
the line it's 
complaining about, so a comment about an internal error could give a false 
positive.  GCC may not have 
that problem, but it might still get fooled by a file name.
More generally, unless you know all the possible error strings, you might 
miss an error.  So I also 
looked for the absence of the normal correct-rejection strings, which is also 
subject to false positives, 
until you get them all.  OTOH, if you know that returning with exit code 1 
actually means a normal 
rejection, then you don't get annoyed with tricky stuff like (in our case, at 
least) files named after error 
signals.

Thanks very much, patch 9330 works well (though I had to apply the second 
change in gcc.c manually, 
since someone changed commands[i].prog to commands[j].prog later than my copy 
of the 4.0.1 sources).  
I've added a check in my recursive crash-tester for a normal exit code with 
abnormal error text, or 
missing normal rejection text.  It's encountered a couple dozen internal error 
so far, and they all returned 
something other than 0 or 1.  I'm running it on our source tree over the 
weekend.

[Bug c++/23089] New: internal compiler error: in int_mode_for_mode, at stor-layout.c:251 at -O1

2005-07-26 Thread flash at pobox dot com

The session below, with the file below, gives "internal compiler error: in 
int_mode_for_mode, at stor-
layout.c:251".  The error only occurs at -O1 or higher.  This sounds like bug 
17407, but that's 
supposedly fixed and didn't require optimization.  The file is an odd-looking 
Delta reduction of a much 
larger file, which was originally supposed to be valid code; but I haven't 
gotten the include paths set up 
properly yet.

[Bug c++/23125] New: OpenBSD's zic.c causes g++ but not gcc to segfault

2005-07-28 Thread flash at pobox dot com

The OpenBSD file zic.c causes g++ 4.0.1 to segfault, though plain gcc 4.0.1 
does not.  The plainest 
way to reproduce this is to get the OpenBSD version from 
<http://www.openbsd.org/cgi-bin/cvsweb/~checkout~/src/lib/libc/time/zic.c?rev=1.24&content-
type=text/plain>, but I'll attach a Delta-reduced version of our modified copy. 
 g++ 3.3.4 rejects it 
without crashing, but with "confused by earlier errors, bailing out," so this 
is presumably invalid code, 
though it seems to be a popular file.  (Perhaps I should add OpenBSD to section 
I of my article :-)
I'm not sure if this is the same as my two other segfault bugs:  Running 
the --enable-checking 
version under GDB fails to catch the segfault, so I couldn't get a stacktrace.  
(I'm trying to build an --
enable-checking=all version, but it's taken more than twenty-four hours so far.)

The patch looks good on the first of our files to elicit this bug.  The 
following line causes the ICE; the line 
after does not.

I'll crash test the checking=yes version overnight.  (Note that so far I'm only 
crash-testing; I'm not yet 
doing correctness testing.)

The patch looked good in overnight crash-testing over five thousand files in 
our source tree.  I used checking=yes version with patches 8277 and 9330.  I'm 
afraid last night's results aren't directly comparable to my last run with an 
unpatched g++, but the internal errors were a small subset of the unpatched 
version, 4 vs 30.  (Two of those four were bug 23125, one was 23089, and I'll

[Bug c/23225] New: tree check: expected class type, have exceptional (error_mark) in build_pointer_type_for_mode, at tree.c:4246

2005-08-03 Thread flash at pobox dot com

The code below gives the following error:
internal compiler error: tree check: expected class type, have exceptional 
(error_mark) in 
build_pointer_type_for_mode, at tree.c:4246
This sounds like bug 18177, but that was supposedly fixed in 4.0.0.
PalmSource bug 105393.

Here's the code:
typedef int32_t (*ProcPtr)();void Dispatcher(int32_t startCode)   
(__builtin_offsetof (ArgsType, 
largeMsgLen) + sizeof(Args.largeMsgLen)))

"__builtin_offsetof" is necessary for the crash, and is an artifact of 
preprocessing.  This is a Delta-
reduction of a larger file which fails without error under g++ 3.3.4, 
presumably correctly, due to a 
missing include file.

[Bug c++/23307] New: ICE in cp_parser_template_id, at cp/parser.c:8564 with Boost remote_call_manager

2005-08-09 Thread flash at pobox dot com

The file below gives "internal compiler error: in cp_parser_template_id, at 
cp/parser.c:8564".  It's a 
Delta-reduced version of a preprocessed version of the Boost file 
remote_call_manager.cpp, but 
missing some header files.

class remote_call_manager: private noncopyable
{
template
static R execute_now(function &rFunctor);
   inline void remote_call_manager::execute_now(function 
&rFunctor)

This sounds like bug 9781, among others, but that's supposedly fixed.

[Bug c++/23370] New: No error at -O1 for static const class member passed by reference

2005-08-12 Thread flash at pobox dot com

The invalid code below gives an "undefined reference" linker error on GCC 4.0.1 
at -O0, but not at -
O1; GCC 3.3.4 gives an error at both optimizations.  This may not be a bug, if 
the version 4 optimizer is 
being cleverer than the version 3 optimizer; but the failure to reject the 
invalid code might be 
considered a regression.


//By Stuart A. Malone, tweaked by Flash Sheridan

#include 
#include 

class Foo {
public:
 static const uint16_t kErrorCmd = 42;
};

static uint32_t TestCmd(const uint16_t & cmd)
{
 return (cmd == 42) ? 17 : 0;
}

int main()
{
 printf("%u", TestCmd(Foo::kErrorCmd) );
}

Here's the discussion in our developer forum about the validity of this code; 
the rejection was originally 
reported as a bug against our compiler.

I checked a reference manual[1] last night, which said that the 
definition should be:

const int16_t Foo::kVersionNumber;

Keep the "= 3" in the class definition, like you did before.  All 
you're doing with the above line is telling the compiler and linker 
where the storage should be defined.

object in memory, the member must be (uniquely) defined somewhere. 
The initializer may not be repeated: ".

[Bug other/23430] New: configure should allow --comment option

2005-08-16 Thread flash at pobox dot com

When trying to keep track of various builds of GCC, it would be convenient to 
be able to store a 
comment to be read back with -v.  Since -v echoes the full configure command 
line, all that's required 
is not rejecting an argument containing the desired comment.
I'll upload a patch which permits this.  All it does is add a --comment 
option which does nothing; it's 
just seventeen copies of the following, one for each configure file:

  --comment=*)
 ;;#Do nothing; this is just so that the comment will show 
up with -v. 

There may be an easier way for maintainers to patch this, using 
auto-configuration; but I've never 
run that.  There are workarounds, such as embedding configuration information 
into directory names, 
but this approach seems simpler.
A patched checking=yes build passed make check.

Thanks, --with-comment seems to work, but it doesn't seem to be documented.  
Grepping both the 
documentation and source folder didn't find it; Googling for it turned it up in 
the context of MySQL, but 
not GCC.  So I'm re-titling and reopening the bug.  I think the option should 
be listed in --help, but it 
certainly needs to be documented somewhere.

[Bug c++/23472] New: attribute((constructor)) called twice with -funit-at-a-time

2005-08-18 Thread flash at pobox dot com

The constructor in the code for bug 16717 (below) gets called twice when 
compiled by 3.3.4 with -
funit-at-a-time, but only once when called without -funit-at-a-time.  This 
sounds like the opposite of 
bug 16717, which was marked as a 3.4 regression, and supposedly not a problem 
in 3.3.4.

[Bug c/26774] New: Out of memory compiling 9-line Delta-reduced Linux kernel driver msp3400.c

2006-03-20 Thread flash at pobox dot com

The attached 9-line file causes a checking=all build of GCC 4.1.0 to exhaust
memory, on both Ubuntu Linux 5.04/2.6.10-6-386 and Mac OSX 10.4.5.  It's a
Delta-reduced version of a preprocessed version of the Linux Kernel file
drivers/media/video/msp3400.c, which exhibited the same behavior.  The original
compilation was being done by a test script outside the kernel tree, so the
compilation encountered errors; the preprocessed file is invalid C, as is the
Delta-reduced version.
My checking=all builds of GCC 4.0.1 (patched) and 4.02 each give a
segmentation fault.  GCC 3.3.5 (Debian 1:3.3.5-8ubuntu2) gives up cleanly:
"confused by earlier errors, bailing out".
On the non-reduced preprocessed file, with my patched checking build of
4.0.1, I instead get the following, which seems like PR22028, which is
presumably fixed: 
internal compiler error: tree check: expected class type, have
exceptional (error_mark) in 
gimplify_type_sizes, at gimplify.c:4368

Here's the session; I'll attached the preprocessed file and the
Delta-reduction.  I used ulimit on Ubuntu to save time; fully exhausting memory
on OSX (where ulimit doesn't seem to work) with the unreduced file took half an
hour, but memory use gets above 50MB fairly quickly.

[Bug c/26818] New: tree check: expected class ï¿½typeï¿½, have ï¿½exceptionalï¿½ (error_mark) in finish_struct, at c-decl.c:5350 (time.c)

2006-03-22 Thread flash at pobox dot com

The file below causes "internal compiler error: tree check: expected class
'type', have 'exceptional' (error_mark) in finish_struct, at c-decl.c:5350"
with a checking=all build of GCC 4.1.0 on both Ubuntu Linux 5.04 and Mac OSX
10.4.5.  This is a Delta-reduced preprocessed version of the Linux kernel file
arch/x86_64/kernel/time.c; it was originally compiled by a test script outside
of the kernel tree, so it was presumably invalid C.

struct acpi_table_rsdt {
struct acpi_table_header header;
} __attribute__ ((packed));


A checking=all build of GCC 4.0.2 correctly reports an error with no
problem:
/opt/gcc402-chk-all/bin/gcc 
../cpp/bugfiles/GCC_bugfiles/error/122582_time_min.i
../cpp/bugfiles/GCC_bugfiles/error/122582_time_min.i:2: error: field ÂheaderÂ
has incomplete type
This sounds somewhat like PR 22028, but that's marked as fixed in 4.1.0,
and its testcase doesn't cause a problem on my builds of 4.1.0.


Here's the session; I'll upload the file, though its complete contents are
above.

[Bug target/21613] New: -fpic only: internal compiler error: in extract_insn, at recog.c:2083 (20010107-1.c:6)

2005-05-16 Thread flash at pobox dot com

The following gives "internal compiler error: in extract_insn, at 
recog.c:2083", only with -fpic: 

arm-softfloat-linux-gnu-g++ -fpic   ../c/noerror/GPL/20010107-1.c

20010107-1.c is a C Torture file, containing only the following:

unsigned long x[4];
void foo(void)
{
  ((void (*)())(x+2))();
}


This sounds similar to 19960 (darwin/m6811-elf) and 19770 (hppa64/hppa64).
I'll attach the preprocessed file (though it's hardly necessary, since there 
are no #includes), and the -v 
-savetemps output.

Here's the full error message:

../c/noerror/GPL/20010107-1.c: In function `void foo()':

[Bug c/21659] New: "weak declaration must precede definition" error missing at >= O2

2005-05-18 Thread flash at pobox dot com

Compiling the C Torture file "weak-6.c" (below) gives an error at O0 and O1, as 
seemed to be expected 
by the author.  At O2, there's no error or warning.

214> gcc -O2 -c ../c/noerror/GPL/3.3.2/nowarn/bulk/gcc.dg/weak/weak-6.c


215> gcc -O1 -c ../c/noerror/GPL/3.3.2/nowarn/bulk/gcc.dg/weak/weak-6.c
../c/noerror/GPL/3.3.2/nowarn/bulk/gcc.dg/weak/weak-6.c:4: error: weak 
declaration of `foo' must 
precede definition


weak-6.c:
/* { dg-do compile } */

extern void * foo (void);
void * foo (void) { return (void *)foo; } /* { dg-error "precede" } */

#pragma weak foo

Also occurs with arm-softfloat-linux-gnu-g++ 3.4.1.
With Apple gcc version 3.3, I don't get the error at any optimization level.

[Bug c/16031] New: 5.1093e+35 (as a variable) cast to long long => -1

2004-06-16 Thread flash at pobox dot com

The following prints -1; this is undefined behavior per C99 spec §6.3.1.4, but it's 
odd nonetheless, and 
inconsistent with two similar cases, below:

volatile const register float arg2_float_195 = FLT_MAX/666.0;
printf(  " \t %s %lld \n " , "" , ( long long )arg2_float_195  );

(The blank string and parentheses are testing artifacts.)

As an unsigned long, we get 18446744073709551615:
printf(  " \t %s %llu \n " , "" , ( unsigned long long )arg2_float_195  );

As a literal constant, we get 9223372036854775807:
printf(  " \t %s ( long long )5.1093e+35 :\t %lld \n " , "" , ( long long )
5.1093e+35  );



Here's the session; preprocessed file to follow.  Originally found with C99 option on,
