NDS32

    +
  • The variadic function ABI implementation is now compatible to the past + Andes toolchains where caller uses registers to pass arguments and callee + is in charge of pushing them into stack.
    • +
  • The options -mforce-fp-as-gp, -mforbid-fp-as-gp, + and -mex9 have been removed since they are not available yet in + the nds32 port of binutils package.
    • +
  • New option -mcmodel=small/medium/large is provided to + support varied code model on code generation. The -mgp-direct + option now becomes meaningless and can be discarded.
    • +

  • The compiler will now pass the appropriate --isa= option
