--- Comment #75 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I think I could add a simple pattern to handle this.
Basically this:
(set (reg/i:DI 0 x0)
(ior:DI (and:DI (reg:DI 107 [ a ])
(const_int -2031617 [0xffffffffffe0ffff]))
(const_int 458752 [0x70000])))
Should be able to expand back into:
(set (reg 109) (const_int 7 [0x7]))
(set (reg/i:DI 0 x0)
(ior:DI (and:DI (reg/v:DI 104 [ a ])
(const_int -2031617 [0xffffffffffe0ffff]))
(and:DI (ashift:DI (subreg:DI (reg:SI 109 [ t ]) 0)
(const_int 16 [0x10]))
(const_int 2031616 [0x1f0000]))))
