In
some
cases
,
the
strength
reduction
optimization
pass
can
produce
better
code
if
this
is
defined
.
This
macro
controls
the
order
that
induction
variables
are
combined
.
This
macro
is
particularly
useful
if
the
target
has
limited
addressing
modes
.
For
instance
,
the
SH
target
has
only
positive
offsets
in
addresses
.
Thus
sorting
to
put
the
smallest
address
first
allows
the
most
combinations
to
be
found
.
