When building with clang/LLVM in MSVC mode, the msvcrt libraries contain these functions.

When building in a mingw environment, we need to provide them somehow, e.g. via compiler-rt.

The aeabi divmod functions work in the same way as the corresponding __rt_*div* functions for windows, but their parameters are swapped. The functions for converting float to integer and vice versa are the same as their aeabi equivalents, only with different function names.
