piece can always be generated.
The default end of diagnostic path piece was failing to generate on a
BlockEdge that was outgoing from a basic block without a terminator,
resulting in a very simple diagnostic being rendered (ex: no path
highlighting or custom visitors). Reuse another function, which is
essentially doing the same thing and correct it not to fail when a block
has no terminator.

to the underlying consumer implementation. This allows us to unique reports across analyses to multiple functions (which
shows up with inlining).

- Get rid of PathDiagnosticLocation(SourceRange r,..) constructor by providing a bunch of create methods.
- The PathDiagnosticLocation(SourceLocation L,..), which is used by crate methods, will eventually become private.
- Test difference is in the case when the report starts at the beginning of the function. We used to represent that point as a range of the very first token in the first statement. Now, it's just a single location representing the first character of the first statement.
llvm-svn: 139932
- The closing brace is always a single location, not a range.
- The test case previously had a location key 57:1 followed by a range [57:1 - 57:1].
llvm-svn: 139832
- Fix a fixme and move the logic of creating a PathDiagnosticLocation corresponding to a ProgramPoint into a PathDiagnosticLocation constructor.
- Rename PathDiagnosticLocation::create to differentiate from the added constructor.
llvm-svn: 139825
- Modify all PathDiagnosticLocation constructors that take Stmt to also requre LocationContext.
- Add a constructor which should be used in case there is no valid statement/location (it will grab the location of the enclosing function).
llvm-svn: 139763
- It adds LocationContext to the PathDiagnosticLocation object and uses it to lookup the enclosing statement with a valid location.
- So far, the LocationContext is only available when the object is constructed from the ExplodedNode.
- Already found some subtle bugs(in plist-output-alternate.m) where the intermediate diagnostic steps were not previously shown.

class and to bind the shared value using OpaqueValueExpr. This fixes an
unnoticed problem with deserialization of these expressions where the
deserialized form would lose the vital pointer-equality trait; or rather,
it fixes it because this patch also does the right thing for deserializing
OVEs.
Change OVEs to not be a "temporary object" in the sense that copy elision is
permitted.
This new representation is not totally unawkward to work with, but I think
that's really part and parcel with the semantics we're modelling here. In
particular, it's much easier to fix things like the copy elision bug and to
make the CFG look right.
I've tried to update the analyzer to deal with this in at least some
obvious cases, and I think we get a much better CFG out, but the printing
of OpaqueValueExprs probably needs some work.

Eventually there will also be a lib/StaticAnalyzer/Frontend that will handle initialization and checker registration.
Yet another library to avoid cyclic dependencies between Core and Checkers.
