Douglas Gregor acf4fd3039 Stop back-patching 'readonly' Objective-C properties with 'readwrite' ones.
A 'readonly' Objective-C property declared in the primary class can
effectively be shadowed by a 'readwrite' property declared within an
extension of that class, so long as the types and attributes of the
two property declarations are compatible.

Previously, this functionality was implemented by back-patching the
original 'readonly' property to make it 'readwrite', destroying source
information and causing some hideously redundant, incorrect
code. Simplify the implementation to express how this should actually
be modeled: as a separate property declaration in the extension that
shadows (via the name lookup rules) the declaration in the primary
class. While here, correct some broken Fix-Its, eliminate a pile of
redundant code, clean up the ARC migrator's handling of properties
declared in extensions, and fix debug info's naming of methods that
come from categories.

A wonderous side effect of doing this write is that it eliminates the
"AddedObjCPropertyInClassExtension" method from the AST mutation
listener, which in turn eliminates the last place where we rewrite
entire declarations in a chained PCH file or a module file. This
change (which fixes rdar://problem/18475765) will allow us to
eliminate the rewritten-decls logic from the serialization library,
and fixes a crash (rdar://problem/23247794) illustrated by the
test/PCH/chain-categories.m example.

Adrian Prantl 8bf7af3de8 Wrap clang module files in a Mach-O, ELF, or COFF container.
This is a necessary prerequisite for debugging with modules.
The .pcm files become containers that hold the serialized AST which allows
us to store debug information in the module file that can be shared by all
object files that were built importing the module.

This reapplies r230044 with a fixed configure+make build and updated
dependencies and testcase requirements. Over the last iteration this
version adds
- missing target requirements for testcases that specify an x86 triple,
- a missing clangCodeGen.a dependency to libClang.a in the make build.

Nico Weber b6a5d05a8a Remove ASTConsumer::HandleVTable()'s bool parameter.
Sema calls HandleVTable() with a bool parameter which is then threaded through
three layers.  The only effect of this bool is an early return at the last
layer.

Instead, remove this parameter and call HandleVTable() only if the bool is
true.  No intended behavior change.

Alexey Bataev 9772000a22 [OPENMP] Codegen for threadprivate variables
For all threadprivate variables which have constructor/destructor emit call to void __kmpc_threadprivate_register(ident_t * <Current Location>, void *<Original Global Addr>, kmpc_ctor <Constructor>, kmpc_cctor NULL, kmpc_dtor <Destructor>); 
In expressions all references to such variables are replaced by calls to void *__kmpc_threadprivate_cached(ident_t *<Current Location>, kmp_int32 <Current Thread Id>, void *<Original Global Addr>, size_t <Size of Data>, void ***<Pointer to autogenerated cache – array of private copies of threadprivate variable>);
Test test/OpenMP/threadprivate_codegen.cpp checks that codegen is correct. Also it checks that codegen is correct after serialization/deserialization and one of passes verifies debug info.

David Blaikie a51666a4d6 unique_ptr-ify ownership of ASTConsumers
(after fixing a bug in MultiplexConsumer I noticed the ownership of the

ownership up through there too)

David Blaikie 1326975496 DebugInfo: Forward HandleTagDeclRequiredDefinition through MultiplexConsumer to fix debug info emission in the presence of plugins.
When plugins are used the Multiplex(AST)Consumer is employed to dispatch
to both the plugin ASTConsumers and the IRGen ASTConsumer. It wasn't
dispatching a critical call for debug info, resulting in plugin users
having a negative debugging experience.

While I'm here, forward a bunch of other missing calls through the
consumer that seem like they should be there.

To test this, use the example plugin (requires plugins and examples) and
split the test case up so that the plugin testing can be done under that
requirement while the non-plugin testing will execute even in builds
that don't include plugin support or examples.

Hans Wennborg a926d84c4b Emit used/dllexport inline method definitions in nested classes (PR19743, PR11170)
The previous code that was supposed to handle this didn't work
since parsing of inline method definitions is delayed to the end
of the outer class definition. Thus, when HandleTagDeclDefinition()
got called for the inner class, the inline functions in that class
had not been parsed yet.

Richard suggested that the way to do this is by handling inline
method definitions through a new ASTConsumer callback.

I really wanted to call ASTContext::DeclMustBeEmitted() instead of
checking for attributes, but doing that causes us to compute linkage,
and then we fail with "error: unsupported: typedef changes linkage
of anonymous type, but linkage was already computed" on tests like
this: (from SemaCXX/undefined-internal.cpp) :-/

  namespace test7 {
    typedef struct {
      void bar();
      void foo() { bar(); }
    } A;

Eli Friedman 276dd188c4 Note when a decl is used in AST files.
When an AST file is built based on another AST file, it can use a decl from
the fist file, and therefore mark the "isUsed" bit.  We need to note this in
the AST file so that the bit is set correctly when the second AST file is
loaded.

This patch introduces the distinction between setIsUsed() and markUsed() so
that we don't call into the ASTMutationListener callback when it wouldn't
be appropriate.

Fixes PR16635.

This required manually correcting all of the incorrect main-module

I also manually added quite a few missing headers that were uncovered by

Rafael Espindola 189fa748ec Fix a small difference in sema and codegen views of what needs to be output.
In the included testcase, soma thinks that we already have a definition after we
see the out of line decl. Codegen puts it in a deferred list, to be output if
a use is seen. This would break when we saw an explicit template instantiation
definition, since codegen would not be notified.

This patch adds a method to the consumer interface so that soma can notify
codegen that this decl is now required.
