Macros for Functions in generated code.

Hi All, I have a Simulink model that I migrated from 2008a to 2017a, the problem here is when I generate code from that Model the code is different and less efficient, I do think the new implementation takes more memory. Check the following example Version2008a Generate: rt_defines.h #define rt_MIN(ul,u2)( ((u1) <= (u2)) ? (ul) : (u2) ) model.c ParamA= rt_MIN(ParamB+1,ParamC) Version 2017a Generate: rt_defines.h only includes constant parameters(Pi, e, log10) and in the model.c has: if(ParamB+1 <= ParamC) ParamA=ParamB+1 else ParamA=ParamC

Since I am using a lot of these functions (min, max, saturate, etc) I am trying to find the configuration that enables the usage of the "function macros" in the rt_defines.h instead of using the algorithm itself in the code of the model every time that those functions appears. Hope you can understand my problem and help me with it. Thanks
