That's the (unofficial?) name for "like o32 but with 64 bit registers". In other words, argument passing as with o32, but registers are 64 bits and long long data goes in one register rather than in a register pair. mips3 opcodes for 64-bit operations are used. This is an important case for embedded systems, which often need the performance benefits of 64 bit operations. N32 would be a good answer except that it hasn't been available in the past, while o64 has been. paul
