--- Comment #1 from rguenth at gcc dot gnu dot org 2008-06-13 08:14 ---
Confirmed. We do not create a EH region in the first place even though
fprintf and fputs could throw. When CCP folds fputs to fputc it hits
the propagator assert
if (tree_could_throw_p (new_stmt))
{
eh_region = lookup_stmt_eh_region (stmt);
/* We couldn't possibly turn a nothrow into a throw statement. */
gcc_assert (eh_region >= 0);
where /* We couldn't possibly turn a nothrow into a throw statement. */ is
obviously only true if we'd have created a EH region in the first place.
So either that we didn't is a bug or the assert should be
gcc_assert (eh_region >= 0 || tree_could_throw_p (stmt));

If this effects so many platforms this sounds like an important issue to me.
Maybe someone should increase the priority and severity of the issue in this
case?
Andrew, do you plan to fix this issue?

When I compile IdentifierTable.cpp from clang using gcc 4.3.1 I get a crash, compiling with gcc 4.2.4 doesn't crash. If I preprocess it first, and then compile it doesn't crash. If I move the the llvm-svn/llvm/include files to a different folder it doesn't crash. So I am not even able to provide an archive of .cpp and .h files to reproduce since it depends on folder names.

[Bug target/36525] New: prologue code may give invalid stack back chain
The SPU ABI states: "The first word of the stack frame must always point to the previously allocated stack frame (toward higher addresses), except for the first stack frame, which must have a back chain pointer of 0 (NULL)." SPU doesn't have a single instruction that can both write the back chain and adjust the stack pointer, so keeping the above invariant in the presence of interrupts is a little tricky. For frames smaller than 2000 bytes, spu_expand_prologue first writes the back chain word, then adjusts the stack. This is fine since we have a 2000 byte red zone. For frames larger than 2000 bytes, the stack is decremented first, then the back chain word is written. This opens a small window where an interrupt can occur with an uninitialized back chain. If the interrupt handler walks stack frames for some reason, it will see a broken frame. Tools like oprofile are known to have such handlers. A possible solution is to ensure that the back chain write and the stack adjust insns are always in the same dispatch pair. -- Summary: prologue code may give invalid stack back chain Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: amodra at bigpond dot net dot au GCC target triplet: spu-elf http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36525

Hi, I discovered a problem with gfortran 4.3.1 when compiling code with pure function with pointer argument. Inside the pure function, the argument is passed further to an other function.

[Bug target/36527] New: gcc 4.2.x generates wrong code for ARM target
We have encountered what seems to be a gcc bug in the attempt to upgrade our toolchain (using buildroot, embedded ARM no-MMU CPU) from 3.4.6 to 4.2.x. The bug has been seen on both 4.2.3 and 4.2.4. We have not yet been able to build a toolchain based on gcc 4.3.1. Most of our +5 MB system runs fine, but some strange problems we had boiled down to the attached test programs which essentially deals with passing some int parms and a struct through two function calls. The test code fails when executed on the ARM target. It works on x86 using gcc 4.2.3 and also on a MIPS platform using gcc 4.2.1. The test code only fails with -O2.

--- Comment #2 from burnus at gcc dot gnu dot org 2008-06-13 13:30 --- Daniel, as you have implemented the constructor with type spec, maybe you have an idea how to fix this best. The error message is generated in decl.c's gfc_set_constant_character_len. The problem is that for -std=f2003 the same error is generated as if no type-spec were present; gfc_set_constant_character_len is called at three places (with argument array=true). I believe we forgot to test character string when implementing it - and characters are always special due to the LENGTH type parameter. (The length-type parameter of derived types will also be fun, but it will probably not be implemented soon.) -- burnus at gcc dot gnu dot org changed: What|Removed |Added CC||d at domob dot eu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36517

Hi Andrew,
I want to make clear that the 68K backend used to be able to do this
optimization in the GCC 2.9 times. Later with 3.4 or 4.x this optmization did
not work anymore and the code became worth.
Does this make sense in your opinion?
Cheers

I have built with --enable-checking=yes (instead of all), because all was
taking too long.
It looks like a value of a pointer is invalid.
See the gdb session below.
What should I do next to help debug the problem?

[Bug fortran/36528] Cray pointer to function mishandled
--- Comment #1 from burnus at gcc dot gnu dot org 2008-06-13 16:54 --- For gfortran documentation, see: http://gcc.gnu.org/onlinedocs/gfortran/Cray-pointers.html#Cray-pointers a) If used directly, the tree is wrong (see dump), but it works nonetheless (I somehow have not to realize this) b) If used as actual argument, it is completely mishandled. Without explicit interface, it should be: myfunc( (void)(*)(void) pointee) (i.e. "build_pointer_type (build_function_type (void_type_node, NULL_TREE))") and with an explicit interface, it should convert pointee to the tree TYPE of the dummy argument.) c) TODO: Check whether using the pointee as non-procedure actual argument works (incl. VALUE attribute and similar things; it probably works.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36528

[Bug fortran/36526] pointer in pure function
--- Comment #1 from burnus at gcc dot gnu dot org 2008-06-13 17:52 --- CONFIRM. Works with other compilers. The constraint checked for is: "C1272 In a pure subprogram any designator with a base object that is in common or accessed by host or use association, is a dummy argument of a pure function, is a dummy argument with INTENT (IN) of a pure subroutine, or an object that is storage associated with any such variable, shall not be used in the following contexts: [...] (5) As an actual argument associated with a dummy argument with INTENT (OUT) or INTENT (INOUT) or with the POINTER attribute." (From F2003.) At a glance, it seems as if this applies, but as the non-normative note indicates, C1272 does not apply in this case: "NOTE 12.45 Pure subroutines are included to allow subroutine calls from pure procedures in a safe way [...] The constraints for pure subroutines are based on the same principles as for pure functions, except that side effects to INTENT (OUT), INTENT (INOUT), and pointer dummy arguments are permitted." However, I failed to find this in the normative part; I will try a bit more to figure out why C1272 does not apply. -- burnus at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Keywords||rejects-valid Last reconfirmed|-00-00 00:00:00 |2008-06-13 17:52:34 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36526

[Bug fortran/36492] incorrect error when compiling
--- Comment #5 from burnus at gcc dot gnu dot org 2008-06-13 20:25 ---
> First program, causes an ICE.
Valgrind shows that it fails in decl.c's build_struct:
if (c->ts.type == BT_CHARACTER && !c->pointer && c->initializer)
{
int len = mpz_get_si (c->ts.cl->length->value.integer);
As c->ts.cl->length->value is probably a NULL pointer.
Thus for some reason there is no check whether the length is a specification
expression - or actually in this case it needs to be even an initialization
expression.
Possible starting point for investigations: char_len_param_value

since the PR28690 backport. The c[i].s14 read is done using

rather than
movw (%ecx), %di
which is wrong in this case, as %ecx is provably not 32-bit aligned (%ecx - 6
is
known to be 32-bit aligned). Shouldn't be hard to transform this into an
executable testcase (put the array of S14 at the end of mmaped page such that
the last c[i].s14 is right before end of page).
This is a regression since 4.3.0.

aligned_operand looks wrong:
/* Look for some component that isn't known to be aligned. */
if (parts.index)
{
if (REGNO_POINTER_ALIGN (REGNO (parts.index)) * parts.scale < 32)
return 0;
}
if (parts.base)
{
if (REGNO_POINTER_ALIGN (REGNO (parts.base)) < 32)
return 0;
}
We are using the hard registers here so we can have the wrong alignment as they
are shared.
Why are we looking into register pointer's alignment anyways? The MEM_ALIGN
check about should give the correct information anyways.

mentioned we maybe shouldn't be calling set_reg_attrs_from_value() with a hard
