================
Comment at: clang/docs/LanguageExtensions.rst:3135
+
+This predicates all the array references inside the loop to be aligned. The aligned access to them can increase fetch time and increase the performance. 
+
----------------
What does this actually mean, in the end?
Will it assume that whatever alignment is required
for whatever vectorization width chosen,
is the actual alignment?
