Yes, it has been optimized. Real Time Workshop supports virtually all of the data types you need, whether they are floating point, fixed point, or boolean. Many current controls companies (like the one I work for) put auto-generated code from Simulink into production controllers. My previous company first put it into production in 2004, with good results.

As a side note, for the first three years of autonomous (2003-2005) my teams used Simulink to do all of our autonomous control. We auto-generated the code using TargetLink (a third party product from dSPACE). The microcontroller we used wasn't particularly powerful so we did it all in 16-bit fixed point types (with a few 32-bit calculations where we needed the extra accuracy). We even had Stateflow going to do the big-picture sequencing. That's when I first got the basic robot simulator going to test and debug the autonomous code. It really helped finding out where we had precision problems in the fixed point calculations.
