George Koehler cfbc537959 In powerpc ncg, add a speed hack for sti 8. ... ncg is too slow with this many registers. A stack pattern "with GPR GPR GPR" or "with REG REG REG" takes too long to pick registers, causing ncg 8 to take about 2 seconds on each sti 8. I introduce REG_PAIR and there are only 4 such pairs. For programs that use sti 8 (including C programs that copy 8-byte structs), this speed hack improves the ncg run from several seconds to almost instantaneous. Also add a few COMMENT(...) lines in stacking rules.		2016-10-17 20:31:59 -04:00
