They are defined by the ARM compiler which has them documented here:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0491c/BABJFCGC.html
With either -funroll-loops or -O3 (which enables sometimes full unrolling), the
compiler is able to figure out the argument j is a constant as it duplicates it
4 times.
