struct C : public A, public B {

(const_int 0 [0x0]))) 237 {*bstzhireg} (nil)

is transformed to
(insn 16 13 17 2 (set (pc)
(if_then_else (ne (cc0)
(const_int 0 [0x0]))

(pc))) 181 {branch_true} (nil)

(expr_list:REG_BR_PROB (const_int 5347 [0x14e3])
(nil)))
Note that the combiner puts a branch instruction one insn
before the last insn in the basic block.

Just for a reference, here is execute/20030128-1.c.
unsigned char x = 50;
volatile short y = -5;
int main ()
{
x /= y;
if (x != (unsigned char) -10)
abort ();
exit (0);
}
Now, with -O1, the load of y completely disappears.

Here is a reduced testcase.
volatile short y;

With -O1, this function magically turns into "return 0;" like so
foo:

@ frame_needed = 0, uses_anonymous_args = 0

[Bug bootstrap/27645] New: arm-none-eabi doesn't build
My mainline gcc (with svn revision number 113869) doesn't build
with --target=arm-none-eabi.
While building cc1-dummy, I get:
libbackend.a(options.o):(.rodata+0x4474): undefined reference to
`target_fpe_name'
libbackend.a(options.o):(.rodata+0x44b4): undefined reference to
`target_fpe_name'
A quick inspection of options.c in the build directory reveals that
target_fpe_name is guarded with GCC_DRIVER.
#ifdef GCC_DRIVER
/* Set by -mfp=.
*/
const char *target_fpe_name;
#endif /* GCC_DRIVER */
I am guessing that this bug may have something to do with
2006-05-16 H.J. Lu <[EMAIL PROTECTED]>

(gcc-options.o): New rule.

--- Comment #2 from kazu at gcc dot gnu dot org 2006-05-20 04:57 ---
The whole problem is reduced to the combiner doing wrong simplification
of XOR. Here are some details.
Consider:
extern void abort (void) __attribute__ ((noreturn));
extern void exit (int) __attribute__ ((noreturn));
static int __attribute__((noinline))
foo (int a, int b)
{
int c = a ^ b;
if (c == a)
abort ();
}
int
main (void)
{
foo (0, 1);
exit (0);
}
Note that
c == a <==> a ^ b == a
<==> b == 0
So foo aborts if and only if b == 0. In the above testcase, b gets 1,
so foo shouldn't abort, but it does.
The combiner tries to combine the following two insns. (I'm omitting
clobbers for brevity.)
(set (reg:SI 61)
(xor:SI (reg/v:SI 60 [ b ])
(reg/v:SI 59 [ a ])))
(set (reg:CCZ 17 flags)
(compare:CCZ (reg:SI 61)
(reg/v:SI 59 [ a ])))
The combiner produces
(set (reg:CCZ 17 flags)
(compare:CCZ (reg/v:SI 59 [ a ])
(const_int 0 [0x0])))
Note that this is wrong. What matters is whether b is 0 or not.
Once the problem is reduced to this level,
-march=pentium4 is no longer needed.
Is is just that with -march=pentium4, "k % 2" is expanded using XOR.

[Bug tree-optimization/39007] New: -ftree-loop-distribution ICEs
Consider:
void
foo (int *__restrict__ p, int *__restrict__ q, int count)
{
while (--count >= 0)
{
*p++ = 0;
*q++ = 0;
}
}
I get:
$ ./cc1 -quiet -O2 -ftree-loop-distribution min.c
min.c: In function 'foo':
min.c:2: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
This is as of Revision 143741, which is after the fix for PR
tree-optimization/38997 has gone in:
http://gcc.gnu.org/ml/gcc-cvs/2009-01/msg00752.html
FWIW, if I try:
void
foo (int *__restrict__ p, int *__restrict__ q, int count)
{
int i;
for (i = 0; i < count; i++)
{
*p++ = 0;
*q++ = 0;
}
}
I get:
*** glibc detected *** ./cc1: malloc(): memory corruption: 0xf7efd160 ***
I am guessing that depending on the exact memory allocation pattern,
different parts of memory get corrupted.
