About a new porting of GlobalIsel for RISCV
...ble solution to continue the work,
the implementation of GlobalIsel from Mips is a good example, which
use target-specific "MipsCCState" and "MipsCallLowering::MipsHandler"
to handle Call/Arguments/Return lowering.
For RISCV, there's no "CCAssignFnForCall" or "CCAssignFnForReturn"
functions defined, just like the solution in Mips, a new
target-specific "ValueHandler" will be created to support
