Fixed, sorry this too so long to fix, there were other failures that were
blocking me to commit this patch.

[Bug target/37050] gcc-4.3.1 bootstrap failure on sparc Solaris 10

[Jay dot St dot Pierre at Colorado dot EDU]

I was able to build gcc-4.2.4 using the Sun Studio 12 compiler.  However, I was
unable to compile gcc-4.3.1 with gcc-4.2.4, albeit with different errors than
when I tried to use Sun's gcc.  This time I got a bunch of errors like:

ld: fatal: relocation error: R_SPARC_64: file

Yes, this patch causes all of the tests to pass for the AVR.

Thanks for working to find a solution for the AVR target.

[Bug c++/37070] bogus unreachable warning on throw statement

[sebor at roguewave dot com]

--- Comment #2 from sebor at roguewave dot com  2008-08-09 22:51 ---
I'm not sure what you're trying to say but it sure looks like a bug to me.
How else is one supposed to throw an exception without triggering this
warning?

Btw., the argument of a throw expression can throw, and when it does, it
becomes the thrown object:

$ cat t.C && g++ -O2 -Wunreachable-code t.C && ./a.out; echo $?
struct S { S () { throw 0; } };
void bar () { throw S (); }

int main ()
{
try { bar (); }
catch (int) { return 0; }
return 1;
}
t.C: In constructor ‘S::S()’:
t.C:1: warning: will never be executed
t.C: In function ‘void bar()’:
t.C:2: warning: will never be executed
0

[Bug c++/37070] bogus unreachable warning on throw statement

[pinskia at gcc dot gnu dot org]

--- Comment #1 from pinskia at gcc dot gnu dot org  2008-08-09 22:31 ---
I don't think this is really bogus as the expression inside a throw cannot
throw so GCC is able to optimize away the catch inside that throw.
  [t.cc : 3] try
{
  [t.cc : 3] D.2413 = (int *) D.2410;
  [t.cc : 3] *D.2413 = 0;
}
  catch
{
  [t.cc : 3] <<>>
{

[t.cc : 3] terminate ();

}
}

That catch is not reachable.

So is there any possibility to flag a variable to be expected to overflow and
"wrap around"? I think there is a lot of code in the wild assuming the loop to
run 10 times and d_phase to overflow all the time, becoming negative.

2046 7ff0
2047 8000
That is an overflow.

So is:
4094 fff0
4095 0

As I said - it works for me (i686, gcc (Debian 4.3.1-8) 4.3.1).  Still the
overflow invokes undefined behavior and thus _can_ affect the loop.

--- Comment #10 from manu at gcc dot gnu dot org  2008-08-09 20:38 ---
Yeah, silly me, it obviously fails because there is no "next" pr36901.h to
include.

Since we include limits.h, we are at the mercy of the contents of the limits.h
that is found. This isn't very reliable. We just need to a pedantic warning in
the header. This works in x86_64, could you test on your side?

[Bug c/37067] gcc creating wrong code with -O2

[stefan dot bruens at rwth-aachen dot de]

The expected output is quite clear - 69f0 6a00 - but output is 69f0
0.
The loop should run 10 times, as i does not overflow.
d_phase does overflow after 2048 steps, but this should not influence the loop.

with -O2, gcc seems to do the following:
- d_phase is the same as i*0x10
- the block should run 0x186a0 times
- (0x186a0 * 0x10) & 0x = 0x6a00
- break when d_phase reaches 0x6a00 (1696 increment steps)

with -O3 and -O1, d_phase and i get their own variables
there should be at least a warning

limits.h that the AVR toolchain uses is installed by gcc.

[Bug tree-optimization/36881] [4.4 Regression] Creating runtime relocations for code which does not need it

[rguenth at gcc dot gnu dot org]

--- Comment #3 from rguenth at gcc dot gnu dot org  2008-08-09 18:06 ---
Well, the switch conversion pass should create a locally binding (and hidden)
object to store the values.  If it does not then this certainly is a bug.
Though in this case it looks like it needs to build a table of addresses
of non-locally binding objects?  This it shouldn't do by default either I
guess.

--- Comment #1 from rguenth at gcc dot gnu dot org  2008-08-09 18:01 ---
This works for me as far as I can see (you didn't specify the expected
output, and certainly if the loop doesn't run as often as you want you
may print uninitialized memory).  Anyway, if it doesn't work then it is
because d_phase overflows and so invokes undefined behavior.

I don't have AVR so I cannot know what exactly is going on or test a fix.
However, I guess that the limits.h used by AVR do not use #include_next. So you
could try by adding #include_next in pr36901-system.h, that is:

- #include "pr36901.h"
+ #include_next "pr36901.h"

Could you test that?

Note: configuring with the gnu clocale certainly is a bad idea on darwin,
*cannot* work. The only remaining mystery is why we were protected from this
misconfiguration until some time ago... Anyway, please remove that from your
config and report back, I'm sure the build will be ok (before, do an SVN
update, to be sure, in the meanwhile I fixed an unrelated small issue in the
darwin config, a missing include).

Please investigate why you are compiling the generic ctype_members.cc instead
of the darwin-specific one. In the library nothing changed in this area
recently, for sure.

To confirm that something is going wrong when forcing this different config, at
line 137 of the darwin-specific ctype_members.cc there is *no* do_is function!
For some reason, the generic locale model (thus the generic, instead of the
darwin-specific, ctype_members.cc) is wrongly selected.

[Bug c/37067] New: gcc creating wrong code with -O2

[stefan dot bruens at rwth-aachen dot de]

The following code is producing false results with -O2 optimization (-O1 and O3
are correct):
---
#include 
#define BLOCK_SIZE 10

int main()
{
  int i;
  float block_f[BLOCK_SIZE];
  int d_phase = 0;
  int d_phase_inc = 0x10;

  for (i = 0; i < BLOCK_SIZE; i++){
  block_f[i] = (float)(d_phase);
  d_phase += d_phase_inc;
}

  printf ("%x %x\n", (int)block_f[1695], (int)block_f[1696]);
  return 0;
}
-
With -O2, the loop is run only 0x6a0 times, instead of 0x186a0 times.

gcc is from openSUSE 11.0 (4.3.1 20080507 (prerelease) [gcc-4_3-branch revision
135036] (SUSE Linux)), but fc9 is most probably affected as well.

Failing code is a very simplified test case from gnuradio

[Bug c++/37066] New: partial specialization of function depends on the order

[marc dot glisse at normalesup dot org]

In the following code, adapted from gmpxx, the output is HELLO2. If however I
change the order of the two partial specializations, the output becomes HELLO1.
At least one other compiler I tried outputs HELLO1 in both cases. I know that I
can remove the "template<>" and overload the function instead of partially
specializing it, but I would like to understand why the current code is
failing.


#include 

struct mpz_t{};

template 
class __gmp_expr{};

template 
void __gmp_set_expr(const __gmp_expr &);

typedef __gmp_expr mpz_class;

template <>
void __gmp_set_expr(const __gmp_expr &expr)
{
std::cerr << "HELLO1\n";
}

template 
void __gmp_set_expr(const __gmp_expr &expr)
{
std::cerr << "HELLO2\n";
}

mpz_class a;

--- Comment #11 from schilds at sun dot ac dot za  2008-08-09 07:27 ---
Jeez! After reading what all of you have said ... I see this code does actually
do something as crazy (and simple) as set the logical unit number for a file to
6, in a subroutine (when I had thought they had only done writes). 

Yes, this is a known Fortran issue from way back. I apologise profusely for
wasting your time in the manner I have. Again, I apologise.
