Is it correct that -mipsX in contrast to -march=rXXXX has the difference of not only selecting a specific CPU instruction set but also an abi (o32 or n64)? If so wouldn't it be cleaner to remove -mipsX altogether and use -march=rXXXX and -mabi=o32, etc? The different meanings of these options in different toolchain versions confuse me a lot. What is the final intended usage of these options? -- Guido
