[Bug middle-end/24950] [3.4/4.0/4.1/4.2 Regression] ICE in operand_subword_force
--- Comment #6 from amodra at bigpond dot net dot au 2005-11-21 07:08 --- Testing a fix. The reason gcc-3.3 doesn't fail on this testcase is that the first arg to store_bit_field there is a mem:BLK while gcc-3.4 and gcc-4 pass a mem:SI. Code after the following comment in store_bit_field fails badly, trying to insert a 64-bit field into an SImode reg. /* Get the mode to use for inserting into this field. If OP0 is BLKmode, get the smallest mode consistent with the alignment. If OP0 is a non-BLKmode object that is no wider than MAXMODE, use its mode. Otherwise, use the smallest mode containing the field. */ I think we just need to check that bestmode is at least as big as fieldmode. This will prevent trying to use insv, and fall thru to store_fixed_bit_field, which is what happens with a BLKmode MEM. -- amodra at bigpond dot net dot au changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |amodra at bigpond dot net |dot org |dot au Status|NEW |ASSIGNED Last reconfirmed|2005-11-21 01:53:20 |2005-11-21 07:08:37 date|| Target Milestone|4.0.3 |--- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24950

Removing the pthread_key_delete line eliminates one error. However,
we still are left with:
...

In file included from ../../gcc/gcc/gthr.h:103,

In HP-UX 10.20, we have:

I'll remove the __gthrw stuff for pthread_once_init as a test.

Not really. It's somewhat low priority as it's only a missed optimisation. Although it's listed as a target bug, the fix for this problem in 4.x was actually to the generic code. The root cause of this bug is the fact that the argument pointer can't be eliminated on this target. The copy in function.c prevents this optimisation. It would take some research to find the change which fixed the problem in 4.0. It's possible to get these tests to pass if we change the argument pointer register to a callee saves register. However, this requires creating a frame, saving the register used for the argument pointer and copying the incoming argument pointer to this new register. We could optimise this in cases where the argument pointer isn't needed. However, changes are needed to reload for this. Thus, I don't think a fix along these lines is appropriate for 3.3. The issue in this PR is related to the problem noted in PR 2493. We need to copy or save the argument pointer in order to be able to find saved arguments.

--- Comment #1 from pinskia at gcc dot gnu dot org 2005-11-21 00:40 ---
This comes down to the tree-combiner.
Take the following C functions:
double fabs(double);
double f(double a)
{
return fabs(a)*fabs(a);
}
double f1(double *a)
{
return fabs(*a)*fabs(*a);
}
double f2(double *a)
{
double t = fabs(*a);
return t*t;
}
Only f2 is not optimized.

Re: C++ bug with std::copy and std::pair
Hi, > I have attached a cpp file that (I believe) should compile (and does on > Borland c++). It is the copy at the end that causes a problem - the > while loop is simply doing the same as what the copy should do (just to > show I did the operator<< properly). Copy works for other cases (ints, > floats, etc) and even for my own structs too. I'm just not sure why it > complains about the operator<< function for a std::pair. The short answer is that the behavior implemented by GCC is correct, according to the ISO C++ Standard. Of course I agree that it's somewhat unexpected: you may want to have a look to this thread, for instance: http://tinyurl.com/dtxrx Paolo.

--- Comment #8 from nathan at gcc dot gnu dot org 2005-11-20 19:29 --- I've come to the conclusion that my 21166 patch was overzealous. What I now think is that packing a decl always changes its type except for one case described below. Even when the field's placment happens to work out right, the decl should remain packed (it's just an accident of placement, which is fragile). The exception should be were BITS_PER_UNIT == TYPE_ALIGN (TREE_TYPE (field)). Packing such a field is a no-op, so should not be reflected in the type system. We can place this check when we first attempt to set DECL_PACKED. I think this is sufficient to fix the original problem 21166 was trying to solve. -- nathan at gcc dot gnu dot org changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |nathan at gcc dot gnu dot |dot org |org Status|WAITING |ASSIGNED Last reconfirmed|2005-10-22 06:56:58 |2005-11-20 19:29:49 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23304

[Bug target/24961] New: No constraint letter for destination_operand
There is no way to specify a constraint for an operand of an asm statement that
may only be a destination operand (ie. the first operand of the st insn). If
you try to use the "m" constraint together with the %P operand modifier you can
get invalid asm code when %P expands to a register instead of a number. For
example, the Linux kernel uses this asm statement:
asm volatile ("\n[1:]\tst"#n" %1=%r2%P1\t// %0 gets overwritten by exception
handler\n"
"\t.xdata4 \"__ex_table\", 1b-., 1f-.\n"
"[1:]"
: "=r"(__pu_r8) : "m"(__m(addr)), "rO"(val), "0"(__pu_r8));
Occassionally you'll get an assembler error because the POST_MODIFY is expanded
into a register.

I also found the same problem with a friends fedora core 4 with gcc 4.
I have attached a cpp file that (I believe) should compile (and does on
Borland c++). It is the copy at the end that causes a problem - the
while loop is simply doing the same as what the copy should do (just to
show I did the operator<< properly). Copy works for other cases (ints,
floats, etc) and even for my own structs too. I'm just not sure why it
complains about the operator<< function for a std::pair.
