Comparison 4 numbers without using if action in simulink

I designed a model simulink to find an index of maximum number among 4 numbers, using if action can help me, but the problem is I need to transfer the model into the VHDL code using hdl coder which is not support if action. can someone help me to find a way without using if action, please?

In case you are using Simulink and have access to DSP System Toolbox, max block from the library also provides an optional second output that computes the index where maximum is found.

Use a MATLAB Function Block and call max and examine the second output.
