Argyrios Kyrtzidis 898fdbf82d In Sema::CheckShadow, get the DeclContext from the variable that we are checking
instead from the Scope; Inner scopes in bodies don't have DeclContexts associated with them.

Douglas Gregor a57a66e8d0 Sema::MaybeBindToTemporary() shouldn't treat any expression returning
a glvalue as a temporary. Previously, we were enumerating all of the
cases that coul return glvalues and might be called with
Sema::MaybeBindToTemporary(), but that was gross and we missed the
Objective-C property reference case.

John McCall 93be3f75cc When copy-capturing values for a nested capture, use a BlockDeclRefExpr.

2011-02-07 18:37:40 +00:00
John McCall 351762cda2 A few more tweaks to the blocks AST representation:
- BlockDeclRefExprs always store VarDecls
  - BDREs no longer store copy expressions
  - BlockDecls now store a list of captured variables, information about
    how they're captured, and a copy expression if necessary
    
With that in hand, change IR generation to use the captures data in       
blocks instead of walking the block independently.        

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

Douglas Gregor 606c4ac325 Improve our uniquing of file entries when files are re-saved or are
overridden via remapping. Thus, when we create a "virtual" file in the
file manager, we still stat() the real file that lives behind it so
that we can provide proper uniquing based on inodes. This helps keep
the file manager much more consistent.

To take advantage of this when reparsing files in libclang, we disable
the use of the stat() cache when reparsing or performing code
completion, since the stat() cache is very likely to be out of date in
this use case.

Argyrios Kyrtzidis dd03d8ddaa [analyzer] Fix a false positive of the 'self' initialization checker.
A common pattern in classes with multiple initializers is to put the
subclass's common initialization bits into a static function that receives
the value of 'self', e.g:

   if (!(self = [super init]))
     return nil;
   if (!(self = _commonInit(self)))
     return nil;

It was reported that 'self' was not set to the result of [super init].
Until we can use inter-procedural analysis, in such a call, transfer the
ObjCSelfInitChecker flags associated with 'self' to the result of the call.

Douglas Gregor a522693f66 Improve our handling of the current instantiation for qualified
id-expression, e.g., 

  CurrentClass<T>::member

Previously, if CurrentClass<T> was dependent and not complete, we
would treat it as a dependent-scoped declaration reference expression,
even if CurrentClass<T> referred to the current instantiation.

Douglas Gregor 8b481d8ac2 When a function template's template parameter has a default argument,
it's okay for the following template parameters to not have default

in function templates to an extension warning, since this is a
harmless C++0x extension.

Argyrios Kyrtzidis 7272d9cf36 Implement -Woverloaded-virtual.
The difference with gcc is that it warns if you overload virtual methods only if
the method doesn't also override any method. This is to cut down on the number of warnings
and make it more useful like reported here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20423.
If we want to warn that not all overloads are overriden we can have an additional
warning like -Wpartial-override.

-Woverloaded-virtual, unlike gcc, is added to -Wmost. Addresses rdar://8757630.

Douglas Gregor e664276bcf Teach SourceManager::getLocation() how to cope with a source file
whose inode has changed since the file was first created and that is
being seen through a different path name (e.g., due to symlinks or
relative path elements), such that its FileEntry pointer doesn't match
a known FileEntry pointer. Since this requires a system call (to
stat()), we only perform this deeper checking if we can't find the
file by comparing FileEntry pointers.

Also, add a micro-optimization where we don't bother to compute line
numbers when given the location (1, 1). This improves the
efficiency of clang_getLocationForOffset().

John McCall f3a8860ee1 More capturing of 'this': implicit member expressions. Getting that
right for anonymous struct/union members led to me discovering some
seemingly broken code in that area of Sema, which I fixed, partly by  
changing the representation of member pointer constants so that    
IndirectFieldDecls aren't expanded.  This led to assorted cleanups with   
member pointers in CodeGen, and while I was doing that I saw some random
other things to clean up.
