Patch by Emerson Murhpy-Hill.

llvm-svn: 50452

This removes the failure in null-deref-ps.c (test suite).

llvm-svn: 50449

EvalStore/EvalLoad to handle all loads/stores from symbolic memory, allowing us
to do checks for null dereferences, etc., at any arbitrary load/store (these
were missed checks before). This also resulted in some major cleanups, some
conceptual, and others just in the structure of the code.

This temporarily introduces a regression in the test suite (null-deref-ps.c)
before I add a new LVal type for structure fields.

The transfer functions for the checker don't do anything special yet in GC mode.

llvm-svn: 50388

Add corresponding enum in LangOptions.

llvm-svn: 50387

std::pair<CFGBlock*, CFGBlock*> that have an 8-byte alignment for use with
ProgramPoint. This fixes a bug reported by Argiris where using std::set<> on
Windows would result in a 4-byte alignment, not an 8-byte alignment.

Fixes: <rdar://problem/5892265>

This is the same for functions and it's preferable to have the namespace as DeclContext during ActOnPopScope.

-NamespaceDecl for the AST
-Checks for name clashes between namespaces and tag/normal declarations.

This commit doesn't implement proper name lookup for namespaces.

Make assertions for all addresses passed to ProgramPoint that they have at least an 8-byte alignment.

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

llvm-svn: 50283

reimplemented in Sema someday.  This is tracked in PR2236.  Until then
disabling it removes some bogus diagnostics (see 2236).

Don't emit empty strings for path diagnostics when taking the default branch of a switch statement that has no label.

llvm-svn: 50242

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.
