--- Comment #2 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Successfully matched this instruction:
(set (reg/i:DI 0 x0)
(ior:DI (and:DI (reg/v:DI 92 [ b ])
(const_int 4294967295 [0xffffffff]))
(ashift:DI (subreg:DI (reg:SI 100) 0)
(const_int 32 [0x20]))))
rejecting combination of insns 10 and 15
original costs 4 + 4 = 8
replacement cost 12
But this is just BFI, so it's a costing issue.
