Still I need to select sparc_cpu and leon.md too. I could then add -mtune=leon at compiletime to switch sparc_cpu, but the I have to give -mtune=leon every time. I would like to be able to make it the default. With just [ --with-cpu=v7/v8 | --with-float=soft/hard | --disable-multilib ] to configure you cant. So then my suggestion would be to use tripple [ --with-cpu=sparcleonv7/sparcleonv8 | --with-float=soft/hard | --disable-multilib ] to configure. And add the 2 cpu types sparcleonv7,sparcleonv8 that would replace v7/v8. Does this sound good? -- Greetings Konrad
