Zero Overhead Loop Setup
LOOP loop_name LC0 = Preg >> 1 LOOP_BEGIN loop_name LOOP_END loop_name ... is mapped
to... LSETUP ( pcrel5m2, pcrel11m2 ) LC0 = Preg >> 1 ... where the address of LOOP_BEGIN
determines pcrel5m2, and the address of LOOP_END determines pcrel11m2.
Zero Overhead Loop Setup
LOOP loop_name LC1 LOOP_BEGIN loop_name LOOP_END loop_name ... is mapped to... LSETUP
