 // The live registers are:
 //   o r1: the JS function object being called (i.e., ourselves)
 //   o cp: our context
-//   o pp: our caller's constant pool pointer (if FLAG_enable_ool_constant_pool)
+//   o pp: our caller's constant pool pointer (if enabled)
 //   o fp: our caller's frame pointer
 //   o sp: stack pointer
 //   o lr: return address
 //
 // The function builds a JS frame.  Please see JavaScriptFrameConstants in
 // frames-arm.h for its layout.
