Will not be fixed in 4.1.1; adjust target milestone to 4.1.2.

Tom, this hasn't been reconfirmed in a while. Does this bug still exist in
gcj?

------- Comment #13 from rguenth at gcc dot gnu dot org 2009-03-20 22:44 -------
It at least still happens with 4.3 and I have no belief that it is fixed with
4.4 if comment #3 applies. Code generated is also absymal (-O2):
_ZN1t18__U3c_clinit__U3e_EJvv:
.LFB2:
pushl %ebp
.LCFI0:
movl %esp, %ebp
.LCFI1:
subl $8, %esp
.LCFI2:
movl $4, 4(%esp)
movl $_Jv_intClass, (%esp)
call _Jv_NewPrimArray
movl 4(%eax), %edx
testl %edx, %edx
je .L8
cmpl $1, %edx
movl $5, 8(%eax)
jbe .L9
cmpl $2, %edx
movl $7, 12(%eax)
jbe .L10
cmpl $3, %edx
movl $9, 16(%eax)
jbe .L11
movl $11, 20(%eax)
movl %eax, _ZN1t1xE
leave
ret
.L8:
movl $0, (%esp)
call _Jv_ThrowBadArrayIndex
.L9:
movl $1, (%esp)
call _Jv_ThrowBadArrayIndex
.L10:
movl $2, (%esp)
call _Jv_ThrowBadArrayIndex
.L11:
movl $3, (%esp)
call _Jv_ThrowBadArrayIndex
(4.3 again), we do not seem to be able to CSE the load of the array length
on the tree level and we have no way (still) of commoning the calls to
_Jv_ThrowBadArrayIndex either:
<bb 2>:
D.241 = _Jv_NewPrimArray (&_Jv_intClass, 4);
D.249 = D.241->length;
if (D.249 != 0)
goto <bb 4>;
else
goto <bb 3>;
<bb 3>:
_Jv_ThrowBadArrayIndex (0);
<bb 4>:
D.241->data[0] = 5;
D.263 = D.241->length;
if ((unsigned int) D.263 > 1)
goto <bb 6>;
else
goto <bb 5>;
<bb 5>:
_Jv_ThrowBadArrayIndex (1);
<bb 6>:
D.241->data[1] = 7;
D.277 = D.241->length;
if ((unsigned int) D.277 > 2)
goto <bb 8>;
else
goto <bb 7>;
<bb 7>:
_Jv_ThrowBadArrayIndex (2);
<bb 8>:
D.241->data[2] = 9;
D.291 = D.241->length;
if ((unsigned int) D.291 > 3)
goto <bb 10>;
else
goto <bb 9>;
<bb 9>:
_Jv_ThrowBadArrayIndex (3);
<bb 10>:
D.241->data[3] = 11;
x = D.241;
return;
