+@node Cilk Plus Transformation
+@section Cilk Plus Transformation
+@cindex CILK_PLUS
+
+If Cilk Plus generation (flag @option{-fcilkplus}) is enabled, all the Cilk
+Plus code is transformed into equivalent C and C++ functions. In addition, all
+the necessary function calls to the Cilk runtime library
+(located in libcilkrts directory) are inserted (only used by Cilk keywords).
+Majority of this transformation occurs toward the end of the parsing and
+right before the gimplification pass.
+
+These are the major components to the Cilk Plus language extension:
+@itemize @bullet
+@item Array Notations:
+During parsing phase, all the array notation specific information is stored in
+@code{ARRAY_NOTATION_REF} tree using the function
+@code{c_parser_array_notation}. During the end of parsing, we check the entire
+function to see if there are any array notation specific code (using the
+function @code{contains_array_notation_expr}). If this function returns
+true, then we expand them using either @code{expand_array_notation_exprs} or
+@code{build_array_notation_expr}. For the cases where array notations are
+inside conditions, they are transformed using the function
+@code{fix_conditional_array_notations}. The C language-specific routines are
+located in @file{c/c-array-notation.c} and the equivalent C++ routines are in
+file @file{cp/cp-array-notation.c}. Common routines such as functions to
+initialize builtin functions are stored in @file{array-notation-common.c}.
+@end itemize
+
+Detailed information about Cilk Plus is provided in
+@w{@uref{http://www.cilk.com/}}. It is worth mentioning that the current
+implementation follows ABI and SPEC version 0.9.
