Intrinsics in ARC GNU vs MWDT
If one is interested in ARC-specific GCC built-ins those might be found in upstream documentation here: https://gcc.gnu.org/onlinedocs/gcc/ARC-Built-in-Functions.html.
Note to use listed below intrinsics it’s required to include
arcle.h in your source file that way:
#include <arcle.h>
