Performance improvement. Also, the allocator was using CompactSizeClassMap for
no good reason, so I switched it to DefaultSizeClassMap.

to what is needed for constant islands. The prescan method for Mips16 constant
islands will eventually go away. It is only temporary and should be done
earlier when the instructions are first created or from the DAG. If we keep
it here we need to handle better the situation where constant islands
is called multiple times since don't want to prescan more than once.

I had to move some code and I moved a declaration forward past it's first use
in the function but by nutty coincidence there was another variable of the same
name and type and with completely unrelated function that was declared globally
in the class so no compilation error ensued.
It required some unusual conditions for it to even matter. Caused test
case casts.c in test-suite to fail during compilation with a duplicate
symbol error. I would have noticed it during final code review for this port.

This change is to address the removal of the Python framework
from the Mac OS X 10.9 (Mavericks) SDK, and is the recommended
workaround via https://developer.apple.com/library/mac/technotes/tn2328/_index.html

Clang knows how to use the gnu assembler directly from doing so on linux and
hurd. The existing support worked out of the box on cygwin and mingw and I was
able to bootstrap clang with it in both systems (with pending patches for the
new mingw abi, but that is independent of the assembler).

The following patch enables the non-fragile ABI for the ObjFW runtime.
However, I noticed that it is not possible anymore to disable it with
-fno-objc-nonfragile-abi like it was before. I think this functionality should
be restored, but I guess this is not in scope for 3.4 anymore.

Add a severe penalty for not using column layout for braced lists. If
there are solutions with column layout, these are generally preferable
over bin-packed solutions.
Before:
std::vector<MyValues> aaaaaaaaaaaaaaaaaaa{ aaaaaaa, aaaaaaaaaa, aaaaa,
aaaaaaaaaaaaaaa, aaa, aaaaaaaaaa, a,
aaaaaaaaaaaaaaaaaaaaa, aaaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaa +
aaaaaaaaaaaaaaaaaaa,
aaaaaaa, a };
After:
std::vector<MyValues> aaaaaaaaaaaaaaaaaaa{
aaaaaaa, aaaaaaaaaa,
aaaaa, aaaaaaaaaaaaaaa,
aaa, aaaaaaaaaa,
a, aaaaaaaaaaaaaaaaaaaaa,
aaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaa + aaaaaaaaaaaaaaaaaaa,
aaaaaaa, a
};

SmallPtrSet.cpp use different methods if SmallPtrSet.h is included
in C++11 mode. Building llvm in C++03 mode and lldb in C++11 mode
resulted in a link-time failure with the C++11-mode-specific method
not being found in the llvm build.

module. Use the marker to diagnose cases where we try to transition between
submodules when not at the top level (most likely because a closing brace was
missing at the end of a header file, but is also possible if submodule headers
attempt to do something fundamentally non-modular, like our .def files).

Improved the detection of a valid GDB server where we actually can connect to a socket, but then it doesn't read or write anything (which happens with some USB mux software).
Host::MakeDirectory() now can make as many intermediate directories as needed.
The testsuite now has very initial support for remote test suite running. When running on a remote platform, the setUp function for the test will make a new directory and select it as the working directory on the remote host.
Added a common function that can be used to create the short option string for getopt_long calls.

proxy. This lets a function pass query a module analysis manager.
However, the interface is const to indicate that only cached results can
be safely queried.
With this, I think the new pass manager is largely functionally complete
for modules and analyses. Still lots to test, and need to generalize to
SCCs and Loops, and need to build an adaptor layer to support the use of
existing Pass objects in the new managers.

This avoids the need for an extra list of SkeletonCUs and associated
cleanup while staging things to be cleaner for further type unit
improvements.
Also hopefully fixes a memory leak introduced in r195166.

We are going to drop debug info without a version number or with a different
version number, to make sure we don't crash when we see bitcode files with
different debug info metadata format.
Make tests more robust by removing hard-coded metadata numbers in CHECK lines.

This is still an experimental attribute, but I wanted it in tree
for review. It may still get yanked.
This attribute can only be applied to a class @interface, not
a class extension or category. It does not change the type
system rules for Objective-C, but rather the implementation checking
for Objective-C classes that explicitly conform to a protocol.
During protocol conformance checking, clang recursively searches
up the class hierarchy for the set of methods that compose
a protocol. This attribute will cause the compiler to not consider
the methods contributed by a super class, its categories, and those
from its ancestor classes. Thus this attribute is used to force
subclasses to redeclare (and hopefully re-implement) methods if
they decide to explicitly conform to a protocol where some of those
methods may be provided by a super class.
This attribute intentionally leaves out properties, which are associated
with state. This attribute only considers methods (at least right now)
that are non-property accessors. These represent methods that "do something"
as dictated by the protocol. This may be further refined, and this
should be considered a WIP until documentation gets written or this
gets removed.
llvm-svn: 195533
This enables a micro-optimization in protocol conformance checking
to not examine the class hierarchy twice per method.
As part of this change, remove the default arguments from lookupInstanceMethod()
and lookupClassMethod(). It was becoming very redundant. For clients
needing the default arguments, have them use the full API instead of
these convenience methods.

Patch by Kim Gräsman!
Laszlo Nagy and me both ran into the same issue with SpecIterator from DeclTemplate.h causing an error:
tools/clang/include/clang/AST/DeclTemplate.h:560:22: error:
no matching constructor for initialization of 'SetIteratorType' (aka
'FoldingSetVectorIterator<clang::FunctionTemplateSpecializationInfo,
typename SmallVector<FunctionTemplateSpecializationInfo *, 8>::iterator>')
SpecIterator() : SetIter() {}
(see e.g. http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-November/033642.html)
The problem is the SpecIterator default constructor which needs a non-existent SetIter default constructor. SpecIterator's default constructor is evidently dead code as any call to it would fail with the above error.
This patch removes it.

This is the last piece of infrastructure needed to effectively support
querying *up* the analysis layers. The next step will be to introduce
a proxy which provides access to those layers with appropriate use of
const to direct queries to the safe interface.

attribute on method declaration and implementation
match. This makes no sense. Most annotations are
meant for declarations only and one is for implementation.
This has been constant source of regresions and hackery to
get around special cases. I am removing this check.
Such checks must be done on a case by case basis and
when it makes sense. For example, it makes sense
for availability/deprecated and I will file a radar
for that. // rdar://15531984
