Argyrios Kyrtzidis 3eaa22af57 In C++ keep unavailable function calls in the AST, like in C/ObjC.
This allows the migrator to visit and fix them.

NAKAMURA Takumi 9a8f13961c Revert r142914 and r142915, due to possibly missing file.
r142914: "Introduce a placeholder type for "pseudo object""
r142915: "Pull the pseudo-object stuff into its own file."

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.

John McCall 50a2c2c19d Catch placeholder types in DefaultLvalueConversion
and DefaultFunctionArrayLvalueConversion.  To prevent
significant regression for should-this-be-a-call fixits,
and to repair some such regression from the introduction of
bound member placeholders, make those placeholder checks
try to build calls appropriately.  Harden the build-a-call
logic while we're at it.

Douglas Gregor b0e6c8a350 Don't allow an rvalue reference to bind to the result of a calling a

Sebastian Redl a72462cdf4 Add a special note for overload resolution when an initializer list argument
cannot be converted.
This is in preparation for overload resolution of initializer lists.
Currently, you will always get this message when you try to pass an init
list to an overloaded function.

Sebastian Redl b49c46c25c Give InitListChecker a verification-only mode, where it neither emits diagnostics nor
builds a semantic (structured) initializer list, just reports on whether it can match
the given list to the target type.
Use this mode for doing init list checking in the initial step of initialization, which
will eventually allow us to do overload resolution based on the outcome.

Francois Pichet 08d2fa0a78 In Microsoft mode(-fms-compatibility), prefer an integral conversion to a floating-to-integral conversion if the integral conversion is between types of the same size.
For example:
 void f(float);
 void f(int);
 int main {
    long a;
    f(a);
 }
Here, MSVC will call f(int) instead of generating a compile error as clang will do in standard mode.
This fixes a few errors when parsing MFC code with clang.

Francois Pichet 0706d203cf Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag.
Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag.

John McCall fec112d50e Contextually converting to 'id' is not a useful operation. Contextually
converting to an arbitrary Objective-C pointer type is.  Without
significantly re-implementing anything, change the API to reflect this,
and as a minor optimization, strip the pointer conversion off before
potentially building it.

Mostly, this removes a really bizarre-looking bit of code from
BuildInstanceMessage.

llvm-svn: 139354
2011-09-09 06:11:02 +00:00
John McCall 9320b87cff Give conversions of block pointers to ObjC pointers a different cast kind
than conversions of C pointers to ObjC pointers.  In order to ensure that
we've caught every case, add asserts to CastExpr that strictly determine
which cast kind is used for which kind of bit cast.

llvm-svn: 139352
2011-09-09 05:25:32 +00:00
Francois Pichet bcf6471010 In Microsoft mode, if we are inside a template class member function and we can't resolve a function call then create a type-dependent CallExpr even if the function has no type dependent arguments. The goal is to postpone name lookup to instantiation time to be able to search into type dependent base classes.
With this patch in, clang will generate only 37 errors (down from 212) when parsing a typical MFC source file.
