Confirmed. Yet another SRA to bitfield magic issue.
Workaround: -fno-tree-sra.
struct A {
short A1 ;
short A2 ;
int A3 ;
};
static struct A __attribute__((noinline))
foo(int b)
{
struct A result;
result.A1 = (short)0;
result.A2 = (short)0;
/* result.A3 is intentionally not initialized */
if (b) {
result.A1 = (short)1;
result.A2 = (short)2;
result.A3 = 3;
return result;
}
return result;
}
extern void abort (void);
int main()
{
struct A myA = foo(0);
if (myA.A1 != 0)
abort ();
return 0;
}

------- Comment #2 from rguenth at gcc dot gnu dot org 2010-04-02 11:47 -------
SRA introduces a use of the uninitialized value when re-constructing the
unsigned long representation. That boils down to later CCP recognizing
the result as undefined and thus:
Visiting statement:
SR.16_25 = (unsigned int) result$A3_24(D);
which is likely UNDEFINED
Visiting statement:
SR.17_26 = (long unsigned int) SR.16_25;
which is likely UNDEFINED
Visiting statement:
SR.18_27 = SR.17_26 << 32;
which is likely UNDEFINED
Visiting statement:
SR.3_34 = SR.18_27 & 0x0ffffffff00000000;
which is likely UNDEFINED
Visiting PHI node: SR.3_2 = PHI <12885032961(2), SR.3_34(3)>
Argument #0 (2 -> 4 executable)
12885032961 Value: CONSTANT 12885032961
Argument #1 (3 -> 4 executable)
SR.3_34 Value: UNDEFINED
PHI node value: CONSTANT 12885032961
Lattice value changed to CONSTANT 12885032961.
and we completely ignore the taken path.
One issue is that
Visiting statement:
SR.3_34 = SR.18_27 & 0x0ffffffff00000000;
which is likely UNDEFINED
is not 100% true - the value is only partially undefined (only the defined
pieces will be used later). But of course that's splitting hairs somewhat
(but it might be the easiest fix for this bug).
tree-ssa-ccp.c:likely_value needs to look at regular rhs operands for
literal constants (see trunk version) but also make sure to re-set
all_undefined_operands if it encounters such.

What about using -O1 -fno-tree-ccp as a workaround rather than -O1
-fno-tree-rsa ?
Isn't it more efficient and more related to the root cause ?
Thanks for your help.
FYI: I was unable to check out the trunk due to firewall restriction (even on
http). I will try it from another connection.

Disabling constant propagation is going to affect code quality a lot
more (and might uncover latent bugs). Anyway, I have a patch for
trunk already.

For 4.4 the test cases (both the original struct-using one and the later
integer-only one) are fixed by backporting r145184 (PR38180 fix) and then
r157944. Either of them alone fixes neither test case. Bootstrapped and
regression tested on x86_64-linux so far.

It only needs the likely_value changes backported (for 4.3 they need to
be adjusted to match the pre-tuples world). I will do the backports once
4.5.0 is out of the door.

Yes, once I find the time to do so - it's slightly non-trivial.
