George Koehler e3672bd66e Allow sp and fp on the fake stack. ... This simplifies parts of the PowerPC table and causes ncg to better decide whether to push sp or fp to the real stack, or coerce it to REG3, or coerce it to REG-REG3, or move it to a regvar. These better decisions remove extra _mr_ instructions. The idea comes from mach/powerpc/arm/table, where SP has a property STACKPOINTER and LB has LOCALBASE. I don't need two properties, so I make one property SPFP for both registers.		2018-01-23 18:18:40 -05:00
