------- Comment #1 from reichelt at gcc dot gnu dot org 2009-02-01 11:03 -------
A slightly more complex testcase crashes in a different place:
============================================================
double foo()
{
double x, y;
asm("" : "=r,r"(x), "=r,r"(y) : "%0,0"(x), "r,r"(0));
return x;
}
============================================================
bug.c: In function 'foo':
bug.c:6: error: Failure trying to reload:
(nil)
bug.c:6: internal compiler error: in gen_reload, at reload1.c:8327
Please submit a full bug report, [etc.]
Again, no ICE without optimization or with float instead of double.

------- Comment #2 from jakub at gcc dot gnu dot org 2009-02-02 10:06 -------
I think the bug is in check_asm_operands/asm_operand_ok.
The latter has:
case '0': case '1': case '2': case '3': case '4':
case '5': case '6': case '7': case '8': case '9':
/* For best results, our caller should have given us the
proper matching constraint, but we can't actually fail
the check if they didn't. Indicate that results are
inconclusive. */
but the former only handles the simple case:
if (c[0] == '%')
c++;
if (ISDIGIT ((unsigned char) c[0]) && c[1] == '\0')
c = constraints[c[0] - '0'];
Together this allows combine to combine something that definitely shouldn't be
combined.
