Project mention: Intel discontinues Nios II IP | /r/FPGA | 2023-06-14

My team has a solution in place already, which was to write all of our floating point code to call macros rather than putting arithmetic in the code. This allowed us to port easily to an RV32IM CPU (a fork of this one) then memory map an FPU onto it, the macros were then changed to atomically access the FPU registers for any floating point arithmetic. In Intel chips we are using the Nios II floating point hardware 2 (which can be instantiated separately), in other vendors we use a combination of operators from the Opencores FPU and this one, depending upon what operators are selected via generics, the maths library will pick up what configuration is used and choose the available operators.
