Extended Description
After roughly Build #16606:16607:MODIFIED, we get the following code in
AWLF:
v = [scalar];
zero = [0];
s2 = sel( zero, v);
_sub_SxS_( s2, scalar);
This is with:
sac2c prdAKD.sac -v1 -nowlf -doawlf -extrema -b11:ebt >crud
in sac/testsuite/optimizations/awlf
This, in turn, cripples AWLFI.
SCCF should replace s2 by scalar, but it's not doing it.
