Major rewrite/refactoring of static analysis engine. We now use
...
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

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

TranslationUnit now owns IdentifierTable, TargetInfo, and Selectors objects
...
when it is constructed via deserialization. This is done by recording a flag
indicating that this is the case, and it deletes these objects by getting
the references stored in the ASTContext object. This fixes some memory
leaks that occurs when we deserialize translation units from bitcode files.
The rationale between having TranslationUnit sometimes own these objects and
sometimes not is that a TranslationUnit object can be constructed from
state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus
in these cases won't own the IdentifierTable or Selectors, etc. During
deserialization, there is no Preprocessor, so somebody needs to own these
objects in order for them to be properly reclaimed.

PathDiagnosticClients now retain ownership of passed PathDiagnostics, requiring
...
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).

Added initial support into the flow-sensitive dataflow solver to visit the Block-level expression
...
in a block's terminator. This expression is visited within a block, but it is accessed by the
terminator. This is important to observe because for live-variables analysis the block-level
expression is live between the terminator and where the expression occurs in the block. So far
this hasn't been an issue to not observe this because the block-level expression used in the
terminator is always the last one in the block, and we have never queried the liveness information
about this point (but before the terminator).

Change the RewriteRope::Chunks data structure from an std::list into
...
a nice shiny B+ Tree variant. This fixes the last of the known algorithmic
issues with the rewriter, allowing a significant speedup. For example,
-emit-html on Ted's 500K .i file speeds up from 26.8s -> 0.64s in a
debug build (41x!) and 5.475s -> 0.132s (41x!) in an optimized build.
This code is functional but needs to be cleaned up, ifdefs removed, better
commented, and moved to a .cpp file. I plan to do this tomorrow.

This patch adds very basic support for parsing and type-checking class

inheritance in C++. It'll parse the base-specifier list, e.g.,
class D : public B1, virtual public B2 { };
and do some of the simpler semantic checks (B1 and B2 are classes;
they aren't unions or incomplete types, etc).

allows the parsing of "class" in addition to "struct" and "union" to

class C { };
class C c1;

C c2;

Do an initial hack at replacing one of the incredibly inefficient
...
(but simple!) datastructures in the rewriter with a more complex but
more efficient one.
This replaces the Deltas vector with a specialized BTree that makes
delta lookups much more efficient. This speeds up -emit-html on a 500K
.i file from 157.154 to 27.127 seconds on my machine (5.8x).
While this code is functional, it isn't very pretty, I have much
refactoring planned for it, and will remove the USE_VECTOR ifdef.
Stay tuned.

refactor Parser::ParseStructDeclaration to return a vector of uninterpreted
...
declarators. This allows the clients (C structs, objc classes, objc
properties, [future] C++ classes) etc, to do custom processing before invoking
an action.
This has two benefits in the short term:
1) objc ivar processing should be split out of ActOnField into its own ActOn method.
2) the new objc ivar action can take visibility info directly, eliminating
AllVisibilities in ParseObjCClassInstanceVariables.
3) objc properties can pass their own special sauce down to sema as well.

Major refactoring/cleanup of GRExprEngine, ExplodedGraph, and BugReporter.
...
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.

Introduce ContextDecl, patch by Argiris Kirtzidis!
...
-Added ContextDecl (no TranslationUnitDecl)
-ScopedDecl class has a ContextDecl member
-FieldDecl class has a ContextDecl member, so that a Field or a ObjCIvar can be traced back to their RecordDecl/ObjCInterfaceDecl easily
-FunctionDecl, ObjCMethodDecl, TagDecl, ObjCInterfaceDecl inherit from ContextDecl. With TagDecl as ContextDecl, enum constants have a EnumDecl as their context.
-Moved Decl class to a "DeclBase.h" along with ContextDecl class
-CurContext is handled by Sema

Change ObjCInterfaceDecl to inherit from NamedDecl (not TypeDecl). While ObjCInterfaceDecl is arguably a TypeDecl, it isn't a ScopedDecl. Since TypeDecl's are scoped, it makes sense to simply treat them as NamedDecl's. I could have fiddled a bit more with the hierarchy (in terms of creating a non-scoped TypeDecl), however this probably isn't worth the effort.
...
I also finished unifying access to scope decl change by converting Sema::getObjCInterfaceDecl() to use Sema::LookupDecl(). This is much cleaner now:-)

Two changes to Sema::LookupDecl() interface.
...
(1) Remove IdLoc (it's never used).
(2) Add a bool to enable/disable lazy builtin creaation (defaults to true).
This enables us to use LookupDecl() in Sema::isTypeName(), which is also part of this commit.
To make this work, I changed isTypeName() to be a non-const member function. I'm not happy with this, however I fiddled with making LookupDecl() and friends const and it got ugly pretty quickly. We can certainly add it back if/when someone has time to fiddle with it. For now, I thought this simplification was more important than retaining the const-ness.

Fix several bugs in array -> pointer decomposition.
...
First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.
Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.
Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").
This adds an ASTContext::getArrayDecayedType member that handles the
non-trivial logic for this seemingly simple operation.

Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl).

- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.

- Some minor indentation changes.

Hack ReadFileFast() to raise the threshold of memory mapped files (from 4->12 pages).

This is a temporary solution to avoid running out of file descriptors (which defaults to 256).

Fix objc ivar lookup. Ivar lookup should occur between lookup
of method-local values and lookup of globals. Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.
Two todo's left:
1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
in the AST. This is a hack.
2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
not correctly handle typedefs and enum constants yet.

some cleanups on top of David's patch. There are still two
...
remaining open issues I've communicated to him:
1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
all parent class ivars) and flattens classes. If A derives from B,
and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.
David, please review.

More cleanups to HTML rewriter API: remove the InsertTag method; was too complicated

Make a major restructuring of the clang tree: introduce a top-level
...
lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
