Very simple so far - we just highlight every allocation and release
site.

which allows values to escape through unknown calls.

Assumes all calls but the malloc family are unknown.

Also, catch a use-after-free when a pointer is passed to a
function after a call to free (previously, you had to explicitly
dereference the pointer value).

optimistic.

TODO: actually implement the pessimistic version of the checker. Ex: it
needs to assume that any function that takes a pointer might free it.

The optimistic version relies on annotations to tell us which functions
can free the pointer.

post visit of CallExpr.

In general, we should avoid using evalCall as it leads to interference
with other checkers.

Revert my patches which removed Diagnostic.h includes by moving some operator overloads out of line.

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.

This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99.

that would break self-host right now. See PR11922.)

Fix all the transitive include users.

llvm-svn: 149783

Fix all the files that depended on transitive includes of Diagnostic.h.
With this patch in place changing a diagnostic no longer requires a full rebuild of the StaticAnalyzer.

[analyzer] Make sure Containers OutOfBounds checker does not crash on undefined arguments, when CF functions are called with wrong number of arguments.

different size):

void* x[] = { ptr1, ptr2, ptr3 };

Check if the triple OS is IOS instead of checking for arm/thumb architectures

StaticAnalyzer: Move ObjC- and CXX-specific methods out of line so checkers that don't care about the language don't have to pull in all the headers.

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.

Specifically, CFArrayCreate's input should be:
'A C array of the pointer-sized values to be in the new array.'

[analyzer] It's possible to have a non PointerType expression evaluate to a Loc value. When this happens, use the default type.

Also, slightly modify the diagnostic message in ArrayBound and DivZero (still use 'taint', which might not mean much to the user, but plan on changing it later).
