(1) libAnalysis is a generic analysis library that can be used by
Sema. It defines the CFG, basic dataflow analysis primitives, and
inexpensive flow-sensitive analyses (e.g. LiveVariables).
(2) libChecker contains the guts of the static analyzer, incuding the
path-sensitive analysis engine and domain-specific checks.
Now any clients that want to use the frontend to build their own tools
don't need to link in the entire static analyzer.
This change exposes various obvious cleanups that can be made to the
layout of files and headers in libChecker. More changes pending. :)
This change also exposed a layering violation between AnalysisContext
and MemRegion. BlockInvocationContext shouldn't explicitly know about
BlockDataRegions. For now I've removed the BlockDataRegion* from
BlockInvocationContext (removing context-sensitivity; although this
wasn't used yet). We need to have a better way to extend
BlockInvocationContext (and any LocationContext) to add
context-sensitivty.

migrate work in the destructors of PathDiagnosticClients from their
destructors to FlushReports(). The destructors now currently call
FlushReports(); this will be fixed in a subsequent patch.

object that it can use to forward PathDiagnostics for further processing. Along
with this feature, the PlistDiagnostics object logs which files are created by
the forwarding of the PathDiagnostics.
(2) Create a new PathDiagnosticClientFactory object for HTMLDiagnostics,
allowing other PathDiagnosticClients to forward PathDiagnostics through an
opaque interface.
(3) Create a "plist-html" diagnostics option in AnalysisConsumer to allow the
logging of HTML files created in a hybrid Plist+HTML diagnostic client.

- Add an (optional) short description for BugReports for clients that want
to distinguish between long and short descriptions for bugs
- Make the bug report for VLA less obscene for Plist diagnostics by using
the short description

This allows it to accurately measure tokens, so that we get:
t.cpp:8:13: error: unknown type name 'X'
static foo::X P;
~~~~~^
instead of the woefully inferior:
t.cpp:8:13: error: unknown type name 'X'
static foo::X P;
~~~~ ^
Most of this is just plumbing to push the reference around.

can use a PathLocation after any reference Stmts are reclaimed,
flattenLocation() converts those references to statements to source ranges.

instead of a FullSourceLoc. This resulted in a bunch of small edits in various
clients.
- Updated BugReporter to include an alternate PathDiagnostic generation
algorithm for PathDiagnosticClients desiring more control-flow pieces.
llvm-svn: 68193
- Added an internal helper class 'PathDiagnosticBuilder' which now bundles the
'ExecutionContinues' methods.
- Added preliminary diagnostics for short-circuit '&&' and '||'
llvm-svn: 67822
- PathDiagnosticControlFlowPiece now consists of a "start" and "end" location
to indicating the branch location and where the branch goes.
BugReporter:
- Updated BugReporter to construct PathDiagnosticControlFlowPiece objects with
"end" locations.
PlistDiagnostics:
- Plists now contain the bug "type" (not just bug "category")
- Plists now encode control-flow pieces differently than events; now the
"start" and "end" locations are recorded
