number + context) to the point where we initially start defining the
lambda, so that the linkage won't change when that information is made
available. Fixes the assertion in <rdar://problem/11182962>.
Plus, actually mangle the context of lambdas properly.

This was caused by the code deciding the number of fields in the byref structure using a different test to the part of the code creating the GEPs into said structure.

Provides an API to run clang tools (FrontendActions) as standalone tools,
or repeatedly in-memory in a process. This is useful for unit-testing,
map-reduce style applications, source transformation daemons or command line
tools.
The ability to run over multiple translation units with different command
line arguments enables building up refactoring tools that need to apply
transformations across translation unit boundaries.
See tools/clang-check/ClangCheck.cpp for an example.

a type specifier and can be combined with unsigned. This allows libstdc++4.7 to
be used with clang in c++98 mode.
Several other changes are still required for libstdc++4.7 to work with clang in
c++11 mode.

be sure to perform the argument type adjustments in
[temp.deduct.call]p2, e.g., array decay.
And, when performing these deductions in the context of 'auto', make
sure that we're deducing the P' in std::initializer_list<P'> rather
than the whole initializer list.
Together, this makes code like
for( auto s : {"Deferred", "New", "Open", "Review"}) { }
work properly.

for converting an empty list to a scalar, be sure to initialize
the source and destination types so that comparison of conversion
sequences will work in case there are multiple viable candidates.

a view over the contents of a DeclContext without exposing the implementation
details of the StoredDeclsMap. Use this in LookupVisibleDecls to find the
visible declarations. Fixes PR12339!

Infinite recursion was happening when DiagnoseInvalidRedeclaration
called ActOnFunctionDeclarator to check if a typo correction works when
the correction was just to the nested-name-specifier because the wrong
DeclContext was being passed in. Unlike a number of functions
surrounding typo correction, the DeclContext passed in for a function is
the context of the function name after applying any nested name
specifiers, not the lexical DeclContext where the
function+nested-name-specifier appears.
llvm-svn: 153962
If we are pre-expanding a macro argument don't actually "activate"
the pragma at that point, activate the pragma whenever we encounter
it again in the token stream.
This ensures that we will activate it in the correct location
or that we will ignore it if it never enters the token stream, e.g:
\#define EMPTY(x)
\#define INACTIVE(x) EMPTY(x)
INACTIVE(_Pragma("clang diagnostic ignored \"-Wconversion\""))
This also fixes the crash in rdar://11168596.

Store this info inside the function summary generated for all analyzed
functions. This is useful for coverage stats and can be helpful for
analyzer state space search strategies.

property file/line rather than the @synthesize file/line. Avoids
some nasty confusing-ness with conflating the file from the scope
and the line from the original declaration. Use the current scope
location as a separate parameter so that we can match it up
better in the line table with the beginning of the scope.
Update a couple of testcases accordingly since I had to change
that we actually use the passed in location in EmitFunctionStart
and for the new metadata parameter and add a new testcase to
make sure we've got the right line numbers for synthesized
properties.

properly reason about such accesses, but we shouldn't emit bogus "uninitialized value" warnings
either. Fixes <rdar://problem/11127008>.

The diagnostic message correctly informs the user that they have omitted the
'class' keyword, but neither suggests this insertion as a fixit, nor attempts
to recover as if they had provided the keyword.
This fixes the recovery, adds the fixit, and adds a separate diagnostic and
corresponding replacement fixit for cases where the user wrote 'struct' or
'typename' instead of 'class' (suggested by Richard Smith as a possible common
mistake).
I'm not sure the diagnostic message for either the original or new cases feel
very Clang-esque, so I'm open to suggestions there. The fixit hints make it
fairly easy to see what's required, though.

move constructor/move assignment operator are not declared, rather than being
defined as deleted, so move operations on the derived class fall back to
copying rather than moving.
If a move operation on the derived class is explicitly defaulted, the
unmovable subobject will be copied instead of being moved.

When indexing a property with a getter/setter with attributes, the allocated memory

It retrieves a source range for a piece that forms the cursors spelling name.
Most of the times there is only one range for the complete spelling but for
objc methods and objc message expressions, there are multiple pieces for each
selector identifier.

These patches cause us to miscompile and/or reject code with static
function-local variables in an extern-C context. Previously, we were
papering over this as long as the variables are within the same
translation unit, and had not seen any failures in the wild. We still
need a proper fix, which involves mangling static locals inside of an
extern-C block (as GCC already does), but this patch causes pretty
widespread regressions. Firefox, and many other applications no longer
build.
Lots of test cases have been posted to the list in response to this
commit, so there should be no problem reproducing the issues.

the nested-name-specifier (e.g., because it is dependent), do not
error even though we can't represent it in the AST at this point.
This is a horrible, horrible hack. The actual feature we still need to
implement (for C++98!) is covered by PR12292. However, we used to
silently accept this code, so when we recently started rejecting it we
caused some regressions (e.g., <rdar://problem/11147355>). This hack
brings us back to the passable-but-not-good state we had previously.
