+\item[scalar renaming]{is the process of renaming scalar variables to

 \section{Loop transformations}
 
+\begin{description}
+
+\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, 
+  generally~1.}
