 +\item[loop unrolling]{
 +  is a loop transformation. 
 +  Unrolling a loop by a factor of $n$ consists in the substitution of a loop
 +  body by itself, replicated $n$ times. A prelude and/or postlude are
 +  added to preserve the number of iteration.}
 +
 +\item[loop fusion]{
 +  is a loop transformation that replaces two loops by a single loops whose
 +  body is the concatenation of the bodies of the two initial loops.}
 +
 +\item[loop tiling]{
 +  is a loop nest transformation that changes the loop execution order
 +  through a partitions of the iteration space into
 +  chunks, so that the iteration is performed over each chunk and in the
 +  chunks.}
 +
 +\item[loop interchange]{is a loop transformation that permutes two
 +  loops from a loop nest.}
 +
 +\item[loop unswitching]{is a loop transformation that replaces a
 +  loop containing a test independent from the loop execution by a test
 +  containing the loop without the test in both true and false branch.}
 +
 +\item[loop normalization]{is a loop transformation that changes
 +  the loop initial increment value or the loop range to enforce certain values,
