I also used -mips2 (an old style of -march=mips2) because -mips3 implied -mabi=64 and I didn't know -mabi=NN option. > What would be the right values for R10K? According to gcc(1) man page no ISA name for R10K is ready, so -march=mips4 -mabi=32 ? Anyway I guess there are few differences between mips3 and mips4, and probably -march=mips2 is enough for performance. (i.e. some pains for mips1 compatibility on mips3 cpus) --- Izumi Tsutsui
