-// Random notes for the static analysis module.
-//===----------------------------------------------------------------------===//
-
-Currently the analyzer with basic store will report false alarm for such code:
-
-p[0] = "/bin/sh";
-p[1] = NULL;
-
-execv(p[0], argv);
-
-This is because BasicStore "collapses" all elements of an array into their base
-region. BasicStore should return UnknownVal() when getLValueElement. But that
-way will break current test in null-deref-ps.c.
-
-//===----------------------------------------------------------------------===//
-
-Investigate what classes of exprs are passed silently in GRExprEngine::Visit().
-
-One is PredefinedExpr.
-
-//===----------------------------------------------------------------------===//
-
-Remove PersistentSValPairs and PersistentSVals?
-
-//===----------------------------------------------------------------------===//
-
-If the pointer is symbolic, we should expand it to a full region with symbolic
-values. This can eliminate the following false warning.
-
-struct file {
-  int lineno;
-};
-
-struct file *fileinfo;
-
-void f10() {
-  int i;
-  int *p = 0;
-  
-  if (fileinfo->lineno)
-    p = &i;
-  
-  if (fileinfo->lineno)
-    *p = 3; // false warning
-}
-
-Now we return a symbolic region for fileinfo->lineno in RegionStore. Loading
-from it returns an UnknownVal. Therefore the path condition is not recorded.
-
-Where should we call this ExpandSymbolicPointer method? Perhaps in
-GRExprEngine::VisitMemberExpr().
-
-Problem: The base expr of MemberExpr can be in various form. How do we get the 
-pointer varregion(or other kind of region) to be changed?
