Needed to change rename.m to set the right include path so we don't
import a broken module due to recursive module checking.

Refine 'objc_protocol_requires_explicit_implementation' attribute to better handle indirect protocols.

This removes an extra "note:", which wasn't really all that more useful
and overall reduces the diagnostic spew for this case.

This reverts commit r197184.

Richard Smith brings up some good points, a proper implementation will
require us to mangle unnameable entities compatibly with MSVC.

Enhance "auto synthesis will not synthesize property in protocol" to include property and protocol name.

This refactor addresses bugzilla bug 18167 and simplifies the code at 
the same time.  Also I add a test case for the bug.  Also I make a 
non-functional change to the basic layout lit tests to make them more 
reliable (using CHECK-NEXT instead of CHECK).

GCC 4.7 changed the MingW ABI. On the clang side this means that methods now
have the thiscall calling convention by default.

getARMCPU and getLLVMArchSuffixForARM existed as very similar functions
in both ToolChain.cpp and Tools.cpp. Create a single implementation of
each in Tools.cpp, eliminate the duplicate and share via Tools.h.

Creates an 'arm' namespace in Tools.h to be used by any ARM-targetting tools.

Passing -mthumb with no explicit CPU on the command line
resulted in target CPU changing from the architecture
default to arm7tdmi. Now it does not.

Thanks to Jonathan Sauer for providing initial test cases.

This refactors some of the Darwin toolchain classification to give a more solid
distinction between the three primary Darwin platforms (OS X, IOS and IOS
simulator) so that a 4th choice can be added temporarily: embedded MachO
targets.

Longer term, this support will be factored out into a separate class and no
longer classified as "darwin-eabi", but the refactoring should still be useful.

This seems to have broken Linux builds, which were failing with the following:

llvm-svn: 197094

Previously, a line like

  // expected-error-re {{foo}}

treats the entirety of foo as a regex. This is inconvenient when matching type
names containing regex characters. For example, to match
"void *(class test8::A::*)(void)" inside such a regex, one would have to type
"void \*\(class test8::A::\*\)\(void\)".

This patch changes the semantics of expected-error-re to only treat the parts
of the directive wrapped in double curly braces as regexes. This avoids the
escaping problem and leads to nicer patterns for those cases; see e.g. the
change to test/Sema/format-strings-scanf.c.

(The balanced search for closing }} of a directive also makes us handle the
full directive in test\SemaCXX\constexpr-printing.cpp:41 and :53.)

No longer accepting attribute spellings with prefix and suffix underscores except for GNU attributes, or C++11-style attributes in the GNU namespace. This prevents attributes such as __declspec(__dllexport__) or [[__noreturn__]] from being treated as known attributes.

[objcmt] When emitting a remap file, use a json format with the edit entries, instead of applying the changes
to a temp file directly.

This allows to combine the edits when they can be different based on whether you saw
the implementation or not, e.g. with the designated initializer migration.

the ObjC implementation declarations, just don't change implementations for
classes that are not in the whitelisted headers.

For example, if we change a method to return 'instancetype' we should also
update the method definition in the implementation.

We were mistakengly giving linkonce_odr linkage instead of internal
linkage to the deleting and complete destructor thunks for classes in
anonymous namespaces.

Fixes PR17273.

llvm-svn: 197060

Methods are thiscall by default in the MS ABI, and also in MinGW targetting GCC 4.7 or later.

This changes the diagnostic from the technically correct but hard to understand:

  virtual function 'foo' has different calling convention attributes ('void ()') than the function it overrides (which has calling convention 'void () __attribute__((thiscall))')

to the more intuitive and also correct:

  'static' member function 'foo' overrides a virtual function

We already have a test for this. Let's just run it in both ABI modes.

Includes might always pull in arbitrary header or data files outside of

This is an experimental feature, where -integrated-as will be
on by default on ARM/Thumb. We aim to detect the missing features
so that the next release is stable.

Updating the ReleaseNotes, too.

Also moving the AArch64 into the same place.

Specifically, we want to warn only for direct layering violations for
the modules we are calling clang on.

This temporarily unblocks

Once that is in, we'll also want to investigate whether to check the
layering in the build step of modules that we build transitively.
