initializers, so that we are within the appropriate subobject after
we've processed a multi-designator designation. We're matching GCC and

Douglas Gregor e4a0bb7a20 Initial implementation of semantic analysis and ASTs for C99
designated initializers. This implementation should cover all of the
constraints in C99 6.7.8, including long, complex designations and
computing the size of incomplete array types initialized with a
designated initializer. Please see the new test-case and holler if you
find cases where this doesn't work.

There are still some wrinkles with GNU's anonymous structs and
anonymous unions (it isn't clear how these should work; we'll just
follow GCC's lead) and with designated initializers for the members of a
union. I'll tackle those very soon.

CodeGen is still nonexistent, and there's some leftover code in the
parser's representation of designators that I'll also need to clean up.

Ted Kremenek fe32cc0ba6 Get RegionStore to work with the retain/release checker and its test cases.

Ted Kremenek 52f73cad4a Fix: <rdar://problem/6510344> [pth] PTH slows down regular lexer considerably (when it has substantial work)
Changes to IdentifierTable:
- High-level summary: StringMap never owns IdentifierInfos.  It just
references them.
- The string map now has StringMapEntry<IdentifierInfo*> instead of
  StringMapEntry<IdentifierInfo>.  The IdentifierInfo object is
  allocated using the same bump pointer allocator as used by the
  StringMap.

Changes to IdentifierInfo:
- Added an extra pointer to point to the
  StringMapEntry<IdentifierInfo*> in the string map.  This pointer
  will be null if the IdentifierInfo* is *only* used by the PTHLexer
  (that is it isn't in the StringMap).

Algorithmic changes:
- Non-PTH case:
   IdentifierInfo::get() will always consult the StringMap first to
   see if we have an IdentifierInfo object.  If that StringMapEntry
   references a null pointer, we allocate a new one from the BumpPtrAllocator
   and update the reference in the StringMapEntry.
- PTH case:
   We do the same lookup as with the non-PTH case, but if we don't get
   a hit in the StringMap we do a secondary lookup in the PTHManager for
   the IdentifierInfo.  If we don't find an IdentifierInfo we create a
   new one as in the non-PTH case.  If we do find and IdentifierInfo
   in the PTHManager, we update the StringMapEntry to refer to it so
   that the IdentifierInfo will be found on the next StringMap lookup.
   This way we only do a binary search in the PTH file at most once
   for a given IdentifierInfo.  This greatly speeds things up for source
   files containing a non-trivial amount of code.

Performance impact:
   While these changes do add some extra indirection in
   IdentifierTable to access an IdentifierInfo*, I saw speedups even
   in the non-PTH case as well.

   Non-PTH: For -fsyntax-only on Cocoa.h, we see a 6% speedup.
   PTH (with Cocoa.h in token cache): 11% speedup.

   I also did an experiment where we did -fsyntax-only on a source file
   including a large header and Cocoa.h, but the token cache did not
   contain the larger header.  For this file, we were seeing a performance
   *regression* when using PTH of 3% over non-PTH.  Now we are seeing
   a performance improvement of 9%!

Tests:
   The serialization tests are now failing.  I looked at this extensively,
   and I my belief is that this change is unmasking a bug rather than
   introducing a new one.  I have disabled the serialization tests for now.

that every declaration lives inside a DeclContext.

Moved several things that don't have names but were ScopedDecls (and,
therefore, NamedDecls) to inherit from Decl rather than NamedDecl,
including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't
store empty DeclarationNames for these things, nor do we try to insert
them into DeclContext's lookup structure.

The serialization tests are temporarily disabled. We'll re-enable them
once we've sorted out the remaining ownership/serialiazation issues
between DeclContexts and TranslationUnion, DeclGroups, etc.

Douglas Gregor dee1be8e95 Teach DeclContext how to find the primary declaration for any TagDecl
even when we are still defining the TagDecl. This is required so that
qualified name lookup of a class name within its definition works (see
the new bits in test/SemaCXX/qualified-id-lookup.cpp).

As part of this, move the nested redefinition checking code into
ActOnTag. This gives us diagnostics earlier (when we try to perform
the nested redefinition, rather than when we try to complete the 2nd
definition) and removes some code duplication.

Douglas Gregor dd04d33e3a Part one of handling C++ functional casts. This handles semantic
analysis and AST-building for the cases where we have N != 1
arguments. For N == 1 arguments, we need to finish the C++
implementation of explicit type casts (C++ [expr.cast]).

This is according to my understanding reading the docs, I don't know if it
really agrees fully with what VC++ allows.

Chris Lattner 53e384f633 Change some terminology in SourceLocation: instead of referring to
the "physical" location of tokens, refer to the "spelling" location.
This is more concrete and useful, tokens aren't really physical objects!
