I still have another concern: we need a mips64r6 default triples to support= . Currently, in my previous patch, I add a "*" between mips and 64, aka mips*64*el-linux-gnu(abi64). If you have concern about some cases, maybe we can define it only for mips*32*-linux-gnu mips*64*-linux-gnuabin32 mips*64*-linux-gnuabi64 Andreas K.
