--- Comment #13 from Hal Finkel <hfinkel at anl.gov> ---
The ADDIS is coming from the regular add pattern:

ISEL: Starting pattern match on root node: 0x70b7480: i32 = add 0x70b4430,
0x70b2c70 [ORD=29] [ID=66]
  Morphed node: 0x70b7480: i32 = ADDIS 0x70b4430, 0x70b2170 [ORD=29]

which was:

              0x70b4430: i32 = PPCISD::GlobalBaseReg [ORD=29]

              0x70b2c70: i32 = PPCISD::Hi 0x70b2170, 0x70b4030 [ORD=29]

            0x70b7480: i32 = add 0x70b4430, 0x70b2c70 [ORD=29]

If we make sure to allocate the global base register from the non-r0 register
class, then this problem goes away ;) -- r203054.
