Unfortunately the new G5 executable of Homer is 10% slower than the 32bit executable. :( (Numbers posted in the previous thread). For comparision, the speedup of 64bit crafty on a G5 is around 50%. (Please consider that on ppc the number and width of registers doesn't change between 32bit and 64bit mode). darwin: $(MAKE) target=DARWIN \ CC=gcc CXX=g++ \ CFLAGS='$(CFLAGS) -Wall -pipe -O2' \ CXFLAGS=$(CFLAGS) \ LDFLAGS=$(LDFLAGS) \ LIBS='-lstdc++' \ opt='$(opt) -DFUTILITY -DFAST' \ crafty-make darwinG5: $(MAKE) target=DARWIN \ CC=gcc CXX=g++ \ CFLAGS='$(CFLAGS) -Wall -pipe -D_REENTRANT -O2 -mcpu=G5 \ -mtune=G5' \ CXFLAGS=$(CFLAGS) \ LDFLAGS='$(LDFLAGS) -lpthread' \ LIBS='-lstdc++' \ opt='$(opt) -DFUTILITY -DSMP -DMUTEX -DPOSIX -DCPUS=4 \ -DPPC64 -DFAST' \ crafty-make Crafty v19.19 White(1): bench Running benchmark. . . ......
