llvm-svn: 142915
2011-10-25 08:42:34 +00:00
John McCall c4a2d3259f Introduce a placeholder type for "pseudo object"
expressions: expressions which refer to a logical rather
than a physical l-value, where the logical object is
actually accessed via custom getter/setter code.
A subsequent patch will generalize the AST for these
so that arbitrary "implementing" sub-expressions can
be provided.

Right now the only client is ObjC properties, but
this should be generalizable to similar language
features, e.g. Managed C++'s __property methods.

Richard Smith d4268d91e7 Don't forget the lvalue-to-rvalue conversion on the LHS when instantiating a

union. This path was missed by the fix in r142890.

Douglas Gregor 4a2a8f7fb8 Check for unexpanded parameter packs in the name that guards a
Microsoft __if_exists/__if_not_exists statement. Also note that we
weren't traversing DeclarationNameInfo *at all* within the
RecursiveASTVisitor, which would be rather fatal for variadic
templates.

llvm-svn: 142906
2011-10-25 03:44:56 +00:00
Douglas Gregor deb4a2be67 Implement support for dependent Microsoft __if_exists/__if_not_exists
statements. As noted in the documentation for the AST node, the
semantics of __if_exists/__if_not_exists are somewhat different from
the way Visual C++ implements them, because our parsed-template
representation can't accommodate VC++ semantics without serious
contortions. Hopefully this implementation is "good enough".

Richard Smith 841222ea75 Don't forget the lvalue-to-rvalue conversion on the LHS of an -> when rebuilding

2011-10-25 00:41:24 +00:00
Douglas Gregor 43edb32f1f Rework Microsoft __if_exists/__if_not_exists parsing and semantic
analysis to separate dependent names from non-dependent names. For
dependent names, we'll behave differently from Visual C++:

  - For __if_exists/__if_not_exists at class scope, we'll just warn
    and then ignore them.
  - For __if_exists/__if_not_exists in statements, we'll treat the
    inner statement as a compound statement, which we only instantiate
    in templates where the dependent name (after instantiation)
    exists. This behavior is different from VC++, but it's as close as
    we can get without encroaching ridiculousness.

The latter part (dependent statements) is not yet implemented.

llvm-svn: 142864
2011-10-24 22:31:10 +00:00
Douglas Gregor 89ab56d5fb When we perform a lookup for a dependent name that is a member of an
unknown specialization, treat this the same way as if the name were
not found in the current instantiation. No actual functionality
change, since apparently nothing depends on this.

Douglas Gregor ebcfbb5d22 When we determine that a function template specialization produced as
part of template argument deduction is ill-formed, we mark it as
invalid and treat it as a deduction failure. If we happen to find that
specialization again, treat it as a deduction failure rather than
silently building a call to the declaration.

Fixes PR11117, a marvelous bug where deduction failed after creating
an invalid specialization, causing overload resolution to pick a
different candidate. Then we performed a similar overload resolution
later, and happily picked the invalid specialization to
call... resulting in a silent link failure.

Richard Smith eb3c10c248 constexpr: semantic checking for constexpr functions and constructors. Based in
part on patches by Peter Collingbourne.

We diverge from the C++11 standard in a few areas, mostly related to checking
constexpr function declarations, and not just definitions. See WG21 paper
N3308=11-0078 for details.

Function invocation substitution is not available in this patch; constexpr
functions cannot yet be used from within constant expressions.

John McCall 32f5fe1467 Add explicit attributes to mark functions as having had their
CoreFoundation object-transfer properties audited, and add a #pragma
to cause them to be automatically applied to functions in a particular

John McCall f1e8b34f6c Add an ns_bridged attribute, used to specify that a
pointer to the annotated struct type can be used as an 
Objective-C object pointer.  If an argument is given, the
type is actually "toll-free bridged" to the specific type 
named there, rather than just to 'id'.

For now, we cannot rely on all types being so annotated,
and we'll always have to have exceptions for things like
CFTypeRef (aka const void*), but this is clearly a good
foundation for improving toolage in this area.
