@opindex fdump-tree-vrp
Dump each function after Value Range Propagation (VRP). The file name
level that @option{-fdump-tree-vect-stats} uses.
Higher verbosity levels mean either more information dumped for each
reported loop, or same amount of information reported for more loops:
-If @var{n}=3, alignment related information is added to the reports.
-If @var{n}=4, data-references related information (e.g.@: memory dependences,
+if @var{n}=3, vectorizer cost model information is reported.
+If @var{n}=4, alignment related information is added to the reports.
+If @var{n}=5, data-references related information (e.g.@: memory dependences,
memory access-patterns) is added to the reports.
-If @var{n}=5, the vectorizer reports also non-vectorized inner-most loops
+If @var{n}=6, the vectorizer reports also non-vectorized inner-most loops
that did not pass the first analysis phase (i.e., may not be countable, or
may have complicated control-flow).

+For @var{n}=9, all the information the vectorizer generates during its
analysis and transformation is reported. This is the same verbosity level
