The intrinsic run-time-support library contains a number of assembly language routines that provide arithmetic and conversion capability for C/C++ operations that the 32-bit and 16-bit instruction sets do not provide. These routines include integer division, integer modulus, and floating-point operations.
There are two versions of each of the routines:
These routines do not follow the standard C/C++ calling conventions in that the naming and register conventions are not upheld. Refer to the ARM Information Center for information on the EABI naming conventions.
