John McCall f8ff7b9fd1 Perform two more constructor/destructor code-size optimizations:
1) emit base destructors as aliases to their unique base class destructors
under some careful conditions.  This is enabled for the same targets that can
support complete-to-base aliases, i.e. not darwin.

2) Emit non-variadic complete constructors for classes with no virtual bases
as calls to the base constructor.  This is enabled on all targets and in
theory can trigger in situations that the alias optimization can't (mostly
involving virtual bases, mostly not yet supported).

These are bundled together because I didn't think it worthwhile to split them,
not because they really need to be.

Douglas Gregor 36c569fb33 Eliminate the default arguments to ASTContext::getFunctionType(),

Douglas Gregor 90d554ecb3 Implement support for parsing pseudo-destructor expression with a nested-name-specifier, e.g.,
typedef int Int;
  int *p;
  p->Int::~Int();

This weakens the invariant that the only types in nested-name-specifiers are tag types (restricted to class types in C++98/03). However, we weaken this invariant as little as possible, accepting arbitrary types in nested-name-specifiers only when we're in a member access expression that looks like a pseudo-destructor expression.

Chandler Carruth f50ef6ed9a Make Decl::isOutOfLine() virtual, and use that to determine when definitions
are for out of line declarations more easily. This simplifies the logic and
handles the case of out-of-line class definitions correctly. Fixes PR6107.

Ted Kremenek 445a603c78 Change InitListExpr to allocate the array for holding references
to initializer expressions in an array allocated using ASTContext.

This plugs a memory leak when ASTContext uses a BumpPtrAllocator to
allocate memory for AST nodes.

In my mind this isn't an ideal solution; it would be nice to have
a general "vector"-like class that allocates memory using ASTContext,
but whose guts could be separated from the methods of InitListExpr
itself.  I haven't gone and taken this approach yet because it isn't
clear yet if we'll eventually want an alternate solution for recylcing
memory using by InitListExprs as we are constructing the ASTs.

CXTranslationUnit.

2010-02-18 20:11:31 +00:00
Douglas Gregor 06dcf0375b Introduce CIndex API functions for displaying a diagnostic, with some
knobs to control formatting. Eventually, I'd like to merge the
implementation of this code with the TextDiagnosticPrinter, so that
it's easy for CIndex clients to produce beautiful diagnostics like the
clang compiler does.

Use this new function to display diagnostics within c-index-test.

llvm-svn: 96603
2010-02-18 19:08:21 +00:00
Douglas Gregor 33cdd81064 Rework how CIndex handles diagnostics. Rather than using a callback,
we attach diagnostics to translation units and code-completion
results, so they can be queried at any time.

To facilitate this, the new StoredDiagnostic class stores a diagnostic
in a serializable/deserializable form, and ASTUnit knows how to
capture diagnostics in this stored form. CIndex's CXDiagnostic is a
thin wrapper around StoredDiagnostic, providing a C interface to
stored or de-serialized diagnostics.

I've XFAIL'd one test case temporarily, because currently we end up
storing diagnostics in an ASTUnit that's never returned to the user
(because it contains errors). I'll introduce a temporary fix for this
soon; the real fix will be to allow us to return and query invalid ASTs.
