[Bug c/18671] New: Structure with bit-field offset is wrong.

[nitins2 at kpitcummins dot com]

Hi,
I am using tool chain built with gcc-3.4-20040813 snapshot.
The structure offset byte is wrong for the following C-source code with "-
mrenesas" option.
Without "-mrenesas" option it gives correct offset that is 4.

The data "b2" of structure "bbb" offset is comming 8 which is wrong, it should 
be 4.

**test.c***
struct aaa{
int a1;
}*zzz;

struct bbb {
 int b1:1;
 int b2;
};

test(){
((struct bbb*)zzz)->b2 = 0x12345678;
}

Command line **
sh-elf-gcc -mrenesas  -S test.c

***test.s**
_test:
mov.l   r14,@-r15
mov r15,r14
mov.l   .L2,r1
mov.l   @r1,r2
mov.l   .L3,r1
mov.l   r1,@(8,r2)  <-WRONG OFFSET 
mov r14,r15
mov.l   @r15+,r14
rts
nop
***

Kindly suggest how to solve this bug.

Thanks in advance.

You *do* realize that the current problem has absolutely nothing to do with
the original report, don't you?  You *do* realize that rewriting a PR like
this is pointless, and you should file a *new* PR to cover the new problem,
don't you?

I'll look at it.

[Bug c++/18670] New: g++ is allowing defaulted parameters in function definition in a weird way

[imran at esscc dot uq dot edu dot au]

First of all let me mention the fact that I do NOT have a copy of the standards
document with me. There, now that its out of the way; here goes...

My understanding is that the trailing N parameters can be defaulted. the
following code shows how some trailing params are defaulted in the function
declaration; but more of them are defaulted in the definition!

// start program
//#include 

void f( int i, int j=0 );
void blah( void );

int main( void )
{
f( 4, 5 ); // if this is f() the program won't compile
blah();
return 0;
}

void f( int i=0, int j )
{
// std::cout << "i -> " << i << " j -> " << j << std::endl;
}

void blah( void )
{
f();
}

// end program

The above simple program illustrates what I have mentioned earlier. The code
compiles fine with this cmdline:

g++ func.cpp -o func

Some people have reported that it compiles and runs fine with gcc 3.4.x as well.
 Although rare, it is possible to observe such code huge projects. If its within
the standards, please ignore.

ps: where do i attach the stuff generated by 'gcc -v -save-temps
all-your-options source-file' as mentioned in the 'how to post bugs in gcc'

(In reply to comment #3)
>> So the actual question is:
>>What has set LIMITS_H_TEST to "true" before, and why isn't it set true
>> anymore?

I believe to have found the cause (testing is still in progress).

LIMITS_H_TEST is being set true in config/t-rtems, but a typo in my patch has
prevented config/t-rtems from being picked up (cf. below).

> Is fixproto being set to yes somehow in
> config.gcc for avr-rtems?
Yes, there is a second, bogus use_fixproto for avr-*-* in config.gcc.

I'll propose it to be removed, soon.

>  Do you have a special stanza
> in your config.gcc for that target that is not checked in?
No, the versions I was comparing actually were my local version before having
commited the patch and the version after I commited the patch.

However, this hint was the key to the cause: A typo had crept into the patch I
had checked in (tmake_files= instead of tmake_file=), probably having crept in
when having transferred the patch from my testing cvs-tree (with further patche
s applied) to my submission cvs-tree.

Oops, I wasn't aware that the locks code was using finalizers.
We had to make special consideration in the reference code for
String.intern; we can do something similar for locks.
This is pretty important, I am going to add it to our 4.0

[Bug libgcj/18266] SIGSEGV in GC_register_finalizer_inner ()

[Hans dot Boehm at hp dot com]

--- Additional Comments From Hans dot Boehm at hp dot com  2004-11-25 01:50 
---
After finally finding time to look at the code, it appears that my earlier 
guesses were correct.

::java::lang::ref::Reference::create in natReference.cc calls 
_Jv_RegisterFinalizer(referent ...), where referent is an arbitrary object, 
which may already have a finalizer.  This is bad news, since the original 
finalizer will be dropped.

The original finalizer may be a Java finalizer, or it may be one that was 
registered by the hash synchronization code to clean up a heavy lock entry for 
the object.  In either case we lose.  (The hash synchronization code is careful 
to not lose the original finalizer.)  In both cases I think, we are likely to 
mostly introduce leaks, and crash only occasionally.  So this may explain some 
other misbehavior.

The fix may require some thought.  At a minimum, we need to export more GC 
functionality, so that the Reference implementation can retrieve the old 
finalizer.  (The hash synchronization code currently cheats and goes directly 
to the GC interface, which should also be fixed.)

I think that so long as Reference gets the ordering right, and doesn't assume 
that all finalizers are Java finalizers, the hash synchronization code should 
work.  It needs to drop the heavy lock before the object is deallocated, and 
while the lock is not held.  I don't think the timing otherwise matters.  If 
the object is resurrected 17 times, we can drop the heavy lock at any of those 
points, recreating it if necessary.

This really needs to be fixed to make any use of References reliable.

[Bug driver/18549] -save-temps option ends with corrupt object file

[h dot rind at mondial dot co dot at]

--- Additional Comments From h dot rind at mondial dot co dot at  
2004-11-25 01:46 ---
the following might be a similar problem:

if h8300-hms-gcc 3.3.1 is called with the -save-temps option on h8300-hms it 
produces
a wrong output architecture.
a call to the linker results in the following error message:
h8300-hms-ld: skipping incompatible main.o when searching for main.o
h8300-hms-ld: cannot find main.o

used call:
h8300-hms-gcc -mh -c -Wall -W -Wcast-qual -Wwrite-strings -Wno-unused -save-
temps main.cpp

i figured out that gcc creates h8300-architecture instead of h8300h, which is 
why
the linker fails. this can be checked with "h8300-hms-objdump.exe -f main.o".

omitting -save-temps resolves the problem.
OS: Win2000 (tested, behaviour can be reproduced)

[Bug target/18668] New: use prescott's fisttp

[commie1 at gmx dot net]

When compiling code that converts a float to an int using -march=prescott gcc
will often use cvtts[sd]2si, but sometimes it will use the old method of:

fnstcw  -2(%ebp) # store the control word
movzwl  -2(%ebp), %eax
orw $3072, %ax   # change it to truncate
movw%ax, -4(%ebp)
fldcw   -4(%ebp) # load that new value
fistpll -16(%ebp)# perform the conversion
fldcw   -2(%ebp) # and load the previous value

which prescott (and beyond, presumably) can reduce to: fisttpll -16(%ebp)

The code in this case was:

unsigned int oof(double d)
{
  unsigned int i;
  i = d;
  return i;
}

I've found hardly any mention of this instruction in the mailinglists, the code
or bugzilla (PR12308). Perhaps the cvtts[sd]2si should be used with unsigned as
well, perhaps there are other reasons not to have fisttp, I'd like to know.

There are at least three DRs affirming that the type is unsigned:1, i.e. a 
type with precision 1.

There are a number of ways we can attack this.  I don't know if any are
appropriate for 4.0 though.

One approach is to go with the phi optimization rewrite which allows it
to work with > 2 predecessors to the PHI block.

Another would be to look at Kazu's work which (IIRC) tried to identify
typecasts which were fed by PHIs with all constant arguments.  It then
removed the typecast and original PHI and installed a new PHI with a
result of the proper type.

A third would be to revamp the jump threading selection code.   In the
early days of the jump threading code we couldn't handle SSA graph
updates if we threaded through a block with side effects.  The new
SSA graph update code handles that case, so the selection code shouldn't
need to be so conservative anymore.

I think ultimately we'll want to do all three.  The question in my mind
is which (if any) are suitable for gcc 4.0.

[Bug middle-end/18071] [3.4/4.0 Regression] -Winline does not respect -fno-default-inline

[giovannibajo at libero dot it]

--- Additional Comments From giovannibajo at libero dot it  2004-11-25 
00:20 ---
The problem appears to be the other way round. The C frontend mark the 
declaration as DECL_DECLARED_INLINE but not as DECL_INLINE because the body is 
not available. The relevant portion of code is this:


else if (declspecs->inline_p)
  {
/* Record that the function is declared `inline'.  */
DECL_DECLARED_INLINE_P (decl) = 1;

/* Do not mark bare declarations as DECL_INLINE.  Doing so
   in the presence of multiple declarations can result in
   the abstract origin pointing between the declarations,
   which will confuse dwarf2out.  */
if (initialized)
  {
DECL_INLINE (decl) = 1;
if (storage_class == csc_extern)
  current_extern_inline = 1;
  }


The C++ frontend instead does not have this issue: by default, all declarations 
marked by DECL_DECLARED_INLINE are also marked with DECL_INLINE. In fact, the 
testcase works even after my patch when compiled with cc1plus.

The code has been there since this patch: http://gcc.gnu.org/ml/gcc-cvs/2001-
12/msg00833.html. It fixed PR 5163. I tried removing the if(initialized) and 
always set DECL_INLINE even for functions with no bodies, and the testcase for 
the bug still succeeds. Maybe the weirdness in dwarf2out has been fixed since 
then.

RTH, do you think it makes sense to remove that check and set DECL_INLINE even 
for functions with no bodies in the C frontend? The C++ FE does that.

[Bug c++/18652] [4.0 regression] ICE on invalid redeclaration

[reichelt at gcc dot gnu dot org]

--- Additional Comments From reichelt at gcc dot gnu dot org  2004-11-24 
23:18 ---
IMHO duplicate_decls and/or its callers are broken.
The comment on top of duplicate_decls reads:

  /* If NEWDECL is a redeclaration of OLDDECL, merge the declarations.
 If the redeclaration is invalid, a diagnostic is issued, and the
 error_mark_node is returned.  Otherwise, OLDDECL is returned.

 If NEWDECL is not a redeclaration of OLDDECL, NULL_TREE is
 returned.  */

  tree
  duplicate_decls (tree newdecl, tree olddecl)

But in many situations we return a NULL_TREE, if an error occurred. In fact
we only return an error_mark_node twice. In the first case this leads to
the ICE:

  error ("%q#D redeclared as different kind of symbol", newdecl);
  if (TREE_CODE (olddecl) == TREE_LIST)
olddecl = TREE_VALUE (olddecl);
  cp_error_at ("previous declaration of %q#D", olddecl);

  return error_mark_node;

Changing the error_mark_node into NULL_TREE in fact makes the ICE go away.
However, that causes a minor regression in the testsuite:

  FAIL: g++.dg/other/error8.C duplicate error messages (test for bogus messages,
line 8)
  FAIL: g++.dg/other/error8.C duplicate error messages (test for bogus messages,
line 9)

Looks like the right fix is to make duplicate_decls behave like the comment
says and teach the callers how to handle error_mark_node.
Maybe this even fixes the triple error message in PR18625.

This set of changes seems to have caused the regression:

Or more specifically

If I re-enable walking all of the candidates (as opposed to just the "important"
ones" I get back the optimizations that were present before and this test case
will pass again.

[Bug target/18665] New: -ftrapv borks up simple integer arithmetic

[skunk at iskunk dot org]

A large program was failing mysteriously on our new Opteron box. Went through it
with a fine-toothed debugger, until I came to the line

k -= i;  /*  and  are ints */

Before this line: k == 2, i == 1
 After this line: k == -14, i == 1

Compiling without -ftrapv makes this weirdness go away.

I will attach a tarball containing two .c files and a makefile, basically the
aforementioned big program with all irrelevant code ripped out---just enough to
reproduce the problem.

This bug first came up with 3.4.2, as shipped with Fedora Core 3 (x86-64). I
built 3.4.3 with the below configuration to confirm that the bug is still 
present.

Output from "gcc -v"

[Bug c++/18639] poor out-of-memory handling

[igodard at pacbell dot net]

--- Additional Comments From igodard at pacbell dot net  2004-11-24 22:12

Thank you for the excellent explanation, but your explanation was redundant; I 
do (and did) understand why the nature of the problem is opaque. I'm not filing 
this bug because I don't understand; I'm filing a QOI report because the 
initial 
message wouldn't leave the average user with an understanding.

The actual compiler message in such a case would be much better if it contained 
a brief explanation of the situation like the one you've given here, including 
what the possibilities are, why you don't know, and what to do to narrow down 
the problem on a generic operating system. I am *not* saying you have to fix 
the 
OS; I do feel that you *should* tell the user everything that you know, 
including that you don't know.

This is a situation where message terseness is not a virtue. The existing 
message is confusing and unhelpful, even to will understand the problem and 
what 
to do. I suggested an alternative phrasing; but anything would be better so 
long 
as it explains:

1) was terminated by the OS
2) could have been out of a resource, killed by user request, did a nasty (i.e. 
segv), or something else OS dependent.
3) a generic suggestion for how to find out what was the actual cause
4) how to file a report is nothing else works.

gcc has a generic problem with its messages: they assume the user is 
intimiately 
familiar with the host, the language, and how the compiler works. This makes 
lousy messages for your actual user community.  This is another case of poor 
message QOI.

May I suggest that you circulate this report and its discussion among your 
collegues and see what they think about the general message philosophy and this 
message in particular. I'm giving up here and won't re-open this again, but the 
QOI issue won't go away just because I do.

Ivan

This might be fixed by:
http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02030.html

But since I have not tried it yet and it looks like the build is broken, I 
don't know.

Then mark the static function as used.  Again the problem is related to that 
gcc does not look into the 
string of alias period, except for when writting out the asm.
extern __typeof (foo_internal) work __attribute__ ((alias ("foo_internal")));

[Bug middle-end/15700] [4.0 Regression] [unit-at-a-time] Inlining problem leads to miscompilation of glibc

[hjl at lucon dot org]

--- Additional Comments From hjl at lucon dot org  2004-11-24 21:31 ---
I am not sure why it shouldn't work. Given

static void
foo_internal ()
{
}

extern void (*foo) ();
void
xxx ()
{
  foo = &foo_internal;
}

void
bar ()
{
  foo_internal ();
}

Gcc 4.0 has no problems inlining foo_internal and emitting its body at the
same time. The only difference here is the address of foo_internal vs. an
external alias of foo_internal. In fact, gcc 4.0 does the right thing for

static void
foo_internal ()
{
}

extern void (*foo) ();
void
xxx ()
{
  foo = &foo_internal;
}

extern __typeof (foo_internal) work __attribute__ ((alias ("foo_internal")));

void
bar ()
{
  foo_internal ();
}

Gcc 4.0 has to do inlining and emitting body of a static functon anyway. How
to make it to work with external alias?

Works for me when I change a bity the code as follows:

declare
Message : String (1..5);
begin
String'Read (Channel, Message);
Ada.Text_IO.Put_Line (Message);
end;

I believe the behaviour of the original code is not very well defined
per stream and socket semantics.
