--- Comment #9 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Confirmed.
Looks like the bad instructions are generated somewhere during reload (lra).
Changing pseudo 18915 in operand 0 of insn 198 on equiv
[const(`*.LANCHOR0'+0x80
00)]
Creating newreg=102333, assigning class CORE_REGS to addr r102333
Change to class GENERAL_REGS for r102333

Choosing alt 4 in insn 198: (0) &r (1) r (2) Dd {*arm_adddi3}
Creating newreg=102334, assigning class GENERAL_REGS to r102334
198: {r102334:DI=r18916:DI+0x1;clobber cc:CC;}
REG_DEAD r18916:DI
REG_EQUIV [r88543:SI]
Inserting insn reload before:
125176: r102333:SI=high(const(`*.LANCHOR0'+0x8000))
125177: r102333:SI=r102333:SI+low(const(`*.LANCHOR0'+0x8000))
Oops, those reload insns aren't valid!
