right, which is why gcc ports have options like -march=, -mcpu=, -mtune=, 
etc...  this way you only need 1 gcc to support all these different ISAs.

nds32le-linux-gcc -march=v0 -c ......
nds32le-linux-gcc -march=v1 -c ......
nds32le-linux-gcc -march=v1f -c ......

what i meant was that you don't have to configure gcc for a specific ISA.
