[Bug target/20928] [4.0/4.1 regression] ICE: unrecognizable insns


------- Additional Comments From steven at gcc dot gnu dot org  2005-04-10 16:08 -------
Double *sigh*. 
The old loop optimizer introduces the offending insn.  From the .loop dump: 
 
Insn 26: regno 70 (life 1), move-insn forces 25 savings 1  moved to 56 
Hoisted regno 74 r/o from (mem/u/c:DI (const:DI (unspec:DI [ 
                (symbol_ref:DI ("symbol_tab_data") [flags 0x40] <var_decl 
0x2a95a36270 symbol_tab_data>) 
            ] 2)) [0 S8 A8]) 
... 
(insn 56 55 51 0 (set (reg/f:DI 70) 
        (plus:DI (reg:DI 73) 
            (const_int 1125899906842624 [0x4000000000000]))) -1 (nil) 
    (expr_list:REG_EQUAL (const:DI (plus:DI (symbol_ref:DI ("symbol_tab_data") 
[flags 0x40] <var_decl 0x2a95a36270 symbol_tab_data>) 
                (const_int 1125899906842624 [0x4000000000000]))) 
        (nil)))
