55fc873017f10f6f566b182b70f6fc22aefa3464 04-Dec-2012 Chandler Carruth <chandlerc@gmail.com> Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

This helper function (in the clang::ento::bugreporter namespace) may add more
than one visitor, but conceptually it's tracking a single use of a null or
undefined value and should do so as best it can.

Also, the BugReport parameter has been made a reference to underscore that
it is non-optional.

Because of this, we would previously emit NO path notes when a parameter
is constrained to null (because there are no stores). Now we show where we
made the assumption, which is much more useful.

Essentially, a bug centers around a story for various symbols and regions. We should only include
the path diagnostic events that relate to those symbols and regions.

The pruning is done by associating a set of interesting symbols and regions with a BugReporter, which
can be modified at BugReport creation or by BugReporterVisitors.

This patch reduces the diagnostics emitted in several of our test cases. I've vetted these as
having desired behavior. The only regression is a missing null check diagnostic for the return
value of realloc() in test/Analysis/malloc-plist.c. This will require some investigation to fix,
and I have added a FIXME to the test case.

This seems to negatively affect compile time onsome ObjC tests
(which use a lot of partial diagnostics I assume). I have to come
up with a way to keep them inline without including Diagnostic.h
everywhere. Now adding a new diagnostic requires a full rebuild
of e.g. the static analyzer which doesn't even use those diagnostics.

At this point this is largely cosmetic, but it opens the door to replace
ProgramStateRef with a smart pointer that more eagerly acts in the role
of reclaiming unused ProgramState objects.

5eca482fe895ea57bc82410222e6426c09e63284 06-Jan-2012 Ted Kremenek <kremenek@apple.com> [analyzer] Make the entries in 'Environment' context-sensitive by making entries map from
(Stmt*,LocationContext*) pairs to SVals instead of Stmt* to SVals.

This is needed to support basic IPA via inlining. Without this, we cannot tell
if a Stmt* binding is part of the current analysis scope (StackFrameContext) or
part of a parent context.

This change introduces an uglification of the use of getSVal(), and thus takes
two steps forward and one step back. There are also potential performance implications
of enlarging the Environment. Both can be addressed going forward by refactoring the
APIs and optimizing the internal representation of Environment. This patch
mainly introduces the functionality upon when we want to build upon (and clean up).

8d0ffc7f8c9e7515c54d47b5fd37f8a62850dffb 08-Nov-2011 Anna Zaks <ganna@apple.com> [analyzer] Remove redundant check from DivZeroChecker

Analysis by Ted:
"
if (stateZero && !stateNotZero) {

is checking to see if:

(A) "it is possible for the value to be zero" (stateZero)

AND

(B) "it is not possible for the value to be non-zero" (!stateNotZero)

That said, the only way for both B to be true AND A to be false is if the path is completely infeasible by the time we reach the divide-by-zero check. For the most part (all cases?), such cases should automatically get pruned out at branches (i.e., an infeasible path gets dropped), which is the case in our tests. So the question is whether or not such an infeasible path might not get dropped earlier? I can't envision any right now.

Indeed, the rest of the checker assumes that if the bug condition didn't fire then 'stateNotZero' is non-NULL:

C.addTransition(stateNotZero);
"

Remove dead members/parameters: ProgramState, respondsToCallback, autoTransition.
Remove addTransition method since it's the same as generateNode. Maybe we should
rename generateNode to genTransition (since a transition is always automatically
generated)?

50bbc165b063155cc23c360deb7b865502e068e2 20-Aug-2011 Anna Zaks <ganna@apple.com> Static Analyzer Diagnostics: Kill the addVisitorCreator(callbackTy, void*) API in favor of addVisitor(BugReporterVisitor*).

1) Create a header file to expose the predefined visitors. And move the parent(BugReporterVisitor) there as well.

2) Remove the registerXXXVisitor functions - the Visitor constructors/getters can be used now to create the object. One exception is registerVarDeclsLastStore(), which registers more then one visitor, so make it static member of FindLastStoreBRVisitor.

3) Modify all the checkers to use the new API.
