George Koehler 7e9348169c Add reglap to ncg. Add 4-byte reg_float to PowerPC ncg. ... The new feature "reglap" allows two sizes of floating-point register variables (reg_float), if each register overlaps a single register of the other size. PowerPC ncg uses reglap to define 4-byte instances of f14 to f31 that overlap the 8-byte instances. When ncgg sees the definition of fs14("f14")=f14, it removes the 8-byte f14 from its rvnumbers array, and adds the 4-byte fs14 in its place. Later, when ncg puts a variable in fs14, if it is an 8-byte variable, then ncg switches to the 8-byte f14. The code has /* reglap */ comments in util/ncgg or #ifdef REGLAP in mach/proto/ncg reglap became necessary because my commit a20b87c caused PowerPC ego to allocate reg_float in both 4-byte and 8-byte sizes.		2017-10-14 12:40:04 -04:00
