Richard Smith 034185c2f9 The 'constexpr implies const' rule for non-static member functions is gone in
C++1y, so stop adding the 'const' there. Provide a compatibility warning for
code relying on this in C++11, with a fix-it hint. Update our lazily-written
tests to add the const, except for those ones which were testing our
implementation of this rule.

Argyrios Kyrtzidis c36633c47a [Parser] Don't code-complete twice.
When we are consuming the current token just to enter a new token stream, we push
the current token in the back of the stream so that we get it again.

Unfortunately this had the effect where if the current token is a code-completion one,
we would code-complete once during consuming it and another time after the stream ended.

Fix this by making sure that, in this case, ConsumeAnyToken() will consume a code-completion
token without invoking code-completion.

Richard Smith ad1bbb93d1 PR15290: 'this' is not permitted in the declaration of a friend function,

'this'. Patch by Ismail Pazarbasi!

llvm-svn: 177134
2013-03-15 00:41:52 +00:00
John McCall e68672fed2 Flag that friend function definitions are "late parsed" so that
template instantiation will still consider them to be definitions
if we instantiate the containing class before we get around
to parsing the friend.

This seems like a legitimate use of "late template parsed" to me,
but I'd appreciate it if someone responsible for the MS feature
would look over this.

This file already appears to access AST nodes directly, which
is arguably not kosher in the parser, but the performance of this
path matters enough that perpetuating the sin is justifiable.
Probably we ought to reconsider this policy for very simple
manipulations like this.

The reason this entire thing is necessary is that
function template instantiation plays some very gross games
in order to not associate an instantiated function template
with the class it came from unless it's a definition, and
the reason *that's* necessary is that the AST currently
cannot represent the instantiation history of individual
function template declarations, but instead tracks it in
common for the entire function template.  That probably
prevents us from correctly reporting ill-formed calls to
ambiguously instantiated friend function templates.

Dmitri Gribenko d1c91f1763 Accept over-qualified constructor in MSVC emulation mode
MSVC accepts this:

class A {
  A::A();
};

Clang accepts regular member functions with extra qualification as an MS
extension, but not constructors.  This changes the parser to defer rejecting
qualified constructors so that the same Sema logic can apply to constructors as
regular member functions.  This also improves the error message when MS
extensions are disabled (in my opinion). Before it was:

/Users/jason/Desktop/test.cpp:2:8: error: expected member name or ';' after declaration specifiers
  A::A();
  ~~~~ ^
1 error generated.

After:

/Users/jason/Desktop/test.cpp:2:6: error: extra qualification on member 'A'

If the member has an initializer, assume it was probably intended to be static

If the member doesn't have an initializer, assume it was probably intended to
be const instead of constexpr and suggest that.

(if the attempt to apply these changes fails, don't make any suggestion &
produce the same diagnostic experience as before. The only case where this can
come up that I know of is with a mutable constexpr with an initializer, since
mutable is incompatible with static (but it's already incompatible with
const anyway))

Michael Han 309af291ef Add fixit hints for misplaced C++11 attributes around class specifiers.
Following r168626, in class declaration or definition, there are a combination of syntactic locations 
where C++11 attributes could appear, and among those the only valid location permitted by standard is
between class-key and class-name. So for those attributes appear at wrong locations, fixit is used to 
move them to expected location and we recover by applying them to the class specifier.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module

script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Michael Han 9407e50b04 Improve diagnostic on C++11 attribute specifiers that appear at wrong syntactic locations around class specifiers.
This change list implemented logic that explicitly detects several combinations of locations where C++11 attribute
specifiers might be incorrectly placed within a class specifier. Previously we emit generic diagnostics like 
"expected identifier" for such cases; now we emit specific diagnostic against the misplaced attributes, this also 
fixed a bug in old code where attributes appear at legitimate locations were incorrectly rejected.

Thanks to Richard Smith for reviewing!

John McCall ea0a39e7ad Accept and pass arguments to __unknown_anytype in argument
positions of Objective-C methods.

It is possible to recover a lot of type information about
Objective-C methods from the reflective metadata for their
implementations.  This information is not rich when it
comes to struct types, however, and it is not possible to
produce a type in the debugger's round-tripped AST which
will really do anything useful during type-checking.
Therefore we allow __unknown_anytype in these positions,
which essentially disables type-checking for that argument.
We infer the parameter type to be the unqualified type of
the argument expression unless that expression is an
explicit cast, in which case it becomes the type-as-written
of that cast.
