I am using TM4C1290NCPDT customized board & IAR compiler.
I am looking for the API's absolute - abs(), rotate left - LSL_C(), _prior(), mul32(),div32()
I could find some API's Abs(), LSL_C() ,FPMul() https://developer.arm.com/documentation/ddi0403/latest/ .
To use these API's required any specific include file or #pragma.I am getting errors if I use it directly.
Floating point FPMul() will support integer mul32 as well?.
Arm defines a number of intrinsic functions that can be used with C code to generate explicit instructions. These are supported by the Arm Compiler.
However if using the IAR compiler, you should contact them to find out what is supported.
