Confirmed, a regression from 4.0.0.
I think this is a target bug as you had:
(set (mem:DF (plus:SI (reg/f:SI 7 sp)
(const_int 8 [0x8])) [0 S8 A32])
(const_double:DF -858993460 [0xcccccccc]
2.00000000000000011102230246251565404236316680908e-1 [0x0.ccccccccccccdp-2]))
before loop-invariant but after, you have:
(insn 21 16 17 0 (set (reg:DF 64)
+ (const_double:DF -858993460 [0xcccccccc]
2.00000000000000011102230246251565404236316680908e-1 [0x0.ccccccccccccdp-2]))
-1 (nil)
+ (nil))
Unless -fmove-loop-invariants is not calling emit_move_insn which might be the
issue.
