Hello
C_4i_CF_FPU_Runtime.a contains run time code for Coldfire CPU.
This runtime code is not included in the MSL library, so you need to add both library files to your project.
Run time library includes startup code plus some additional functions for long and long long arithmetic, setjump and others.
This library is already required at link time.
Note that as the linker is performing dead stripping, if the library is not needed, there will be no superfluous code linked to the application. So my recommendation is to always add both libraries to a project.
