The problem is alter_subreg is called during rest_of_handle_flow2 splitting
on (subreg:DI (mem:SI (reg:DI 12 %r12 [orig:46 D.1072 ] [46]) [0 S4 A32]) 0).
As flow2 is already past reload, I think this shouldn't be valid RTL, as per
documentation:
"The reload pass ensures that paradoxical references are only made to hard
registers."
The insn in question is
(insn 77 13 16 0 (set (reg:DI 1 %r1 [51])
(and:DI (subreg:DI (mem:SI (reg:DI 12 %r12 [orig:46 D.1072 ] [46]) [0 S4
A32]) 0)
(const_int 2147483647 [0x7fffffff]))) 98 {*llgt_didi} (nil)
