#pragma import(__use_smaller_memcpy)

This pragma selects a smaller, but slower, version of memcpy() for use with the C micro-library (microlib). A byte-by-byte implementation of memcpy() using LDRB and STRB is used.


Microlib is an alternative library to the default C library. Only use this pragma if you are using microlib.


The default version of memcpy() used by microlib is a larger, but faster, word-by-word implementation using LDR and STR.
