------- Comment #1 from pinskia at gcc dot gnu dot org 2006-12-12 21:56 -------
This is obvious an incorrect RTL instruction:
(insn 973 971 974 95 (set (reg:SI 546)
(subreg:DI (reg/v:TI 355 [ b ]) 8)) -1 (nil)
(nil))
We cannot set a SI from a DI :).

------- Comment #5 from pinskia at gcc dot gnu dot org 2006-12-13 06:40 -------
Reduced testcase:
typedef struct num {
char is_fixnum;
long long ivalue;
} num;
num num_intdiv(num a, num b)
{
num ret;
ret.ivalue = a.ivalue / b.ivalue;
return ret;
}
-----------
On the trunk we get a better ICE:
t.i: In function ‘num_intdiv’:
t.i:8: internal compiler error: in emit_move_insn, at expr.c:3276
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
This comes:
(define_expand "div<mode>3"
[(set (match_operand:GPR 0 "gpc_reg_operand" "")
(div:GPR (match_operand:GPR 1 "gpc_reg_operand" "")
(match_operand:GPR 2 "reg_or_cint_operand" "")))]
""
"
{
if (GET_CODE (operands[2]) == CONST_INT
&& INTVAL (operands[2]) > 0
&& exact_log2 (INTVAL (operands[2])) >= 0)
;
else if (TARGET_POWERPC)
{
operands[2] = force_reg (SImode, operands[2]); <--- this force_reg
but it is obvious we could have DImode here. operands[2] here is a subreg of a
TImode.
I commented out the defintion for MAX_FIXED_MODE_SIZE and it works.
