empty CFGBlocks that only contained a terminator.
Added improved diagnostics for break and continue statements and default branches in switch statements.
This fixes <rdar://problem/5889244>.
llvm-svn: 50286
Implemented support for better localized leaks in the CF reference count checker.
Now leaks should be flagged close to where they occur.
This should implement the desired functionality in <rdar://problem/5879592>, although the diagnostics still need to be improved.
llvm-svn: 50241
them to not be stack-allocated.
HTMLDiagnostics now batches PathDiagnostics before emitting HTML in its dtor.
This is a workaround for a problem when we trampled the Preprocessor state
when highlighting macros (sometimes resulting in an assertion failure).

can decide the policy on how to cache related bugs. This allows us to
properly to handle warning about multiple leaks in the same location in the
ref count checker (not yet done).
llvm-svn: 49918
Shuffled around code in CFRefCount to better pair classes with implementation,
and started adding subclasses of RangedBugReport to handle better diagnostics
for reference count bugs.
llvm-svn: 49889
EmitPathWarning into one method. We now properly handle emitting warnings
without a PathDiagnosticClient when the warning does not involve a particular
statement.

Bugs are now reported using a combination of "BugType" (previously
BugDescription) and Bug "BugReport" objects, which are fed to BugReporter (which
generates PathDiagnostics). This provides a far more modular way of registering
bug types and plugging in diagnostics.
GRExprEngine now owns its copy of GRCoreEngine, and is not owned by the
ExplodedGraph.
ExplodedGraph is no longer templated on the "checker", but instead on the state
contained in the nodes.
llvm-svn: 49453
"BugReporter" and "BugDescription". BugDescription is used to describe
a bug and provide pieces of the PathDiagnostic, and BugReporter creates
the actual PathDiagnostic by crawling through the ExplodedGraph.
Migrated checks done by GRSimpleVals to be reported using the new BugReporter
mechanism.
