<pre>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.</pre>
