The original __gcsss intrinsic was implemented based on: https://github.com/ARM-software/acle/pull/260 with the signature: const void *__gcsss(const void *) Per the updated specification in: https://github.com/ARM-software/acle/pull/364 both const qualifiers have been removed. This commit updates the signature accordingly to: void *__gcsss(void *) This aligns the implementation with the latest ACLE definition.
