This is one of the advantages many compilers see in the use of the "old-fashioned" block COMMON. In the usual case lft==1 all arrays in COMMON are aligned, with the size declarations given here. So it is undesirable to split the loop to handle alignment. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32380
