Objective-C type arguments can be provided in angle brackets following
an Objective-C interface type. Syntactically, this is the same
position as one would provide protocol qualifiers (e.g.,
id<NSCopying>), so parse both together and let Sema sort out the
ambiguous cases. This applies both when parsing types and when parsing
the superclass of an Objective-C class, which can now be a specialized
type (e.g., NSMutableArray<T> inherits from NSArray<T>).
Check Objective-C type arguments against the type parameters of the
corresponding class. Verify the length of the type argument list and
that each type argument satisfies the corresponding bound.
Specializations of parameterized Objective-C classes are represented
in the type system as distinct types. Both specialized types (e.g.,
NSArray<NSString *> *) and unspecialized types (NSArray *) are
represented, separately.

Produce type parameter declarations for Objective-C type parameters,
and attach lists of type parameters to Objective-C classes,
categories, forward declarations, and extensions as
appropriate. Perform semantic analysis of type bounds for type
parameters, both in isolation and across classes/categories/extensions
to ensure consistency.
Also handle (de-)serialization of Objective-C type parameter lists,
along with sundry other things one must do to add a new declaration to
Clang.
Note that Objective-C type parameters are typedef name declarations,
like typedefs and C++11 type aliases, in support of type erasure.

pointer types with the type of the first block pointer in the compile
unit.)

This reverts commit r241244, but restricts SEH support to Win64.
This way, Chromium builds will still fall back on TUs with SEH, and
Clang developers can work on this incrementally upstream while patching
this small predicate locally. It'll also make it easier to review small
fixes.

Describes the general syntax of how it's used with the unfortunate
usage of "subtarget features" and some examples from the x86 port
to help users.

The patch is the same except for the addition of a new test for the
issue that required reverting the dependent llvm commit.
--Original Commit Message--
Pass down the -flto option to the -cc1 job, and from there into the
CodeGenOptions and onto the PassManagerBuilder. This enables gating
the new EliminateAvailableExternally module pass on whether we are
preparing for LTO.
If we are preparing for LTO (e.g. a -flto -c compile), the new pass is not
included as we want to preserve available externally functions for possible
link time inlining.

__attribute__ was treated as the name of a function definition, with the
tokens in parentheses being the parameter list. This formats incorrectly
with AlwaysBreakAfterDefinitionReturnType. Fix it by treating
__attribute__ like decltype.
Patch by Strager Neds, thank you.

an existing using shadow declaration if they define entities of the same kind
in different namespaces.
We'd previously check this consistently if the using-declaration came after the
other declaration, but not if it came before.

CMake-2.8.12 is hardcoded to create symlinked clang.exe if the target property VERSION is present and the host is not Win32.
Then clang.exe-*.* is generated and clang.exe is symlinked to it.
lrwxrwxrwx. 1 bb bb 13 Jul 5 18:04 clang.exe -> clang.exe-3.7
-rwxr-x---. 1 bb bb 244763 Jul 5 18:04 clang++.exe
-rwxr-x---. 1 bb bb 244763 Jul 5 18:04 clang.exe-3.7
It made me unhappy when built binaries were copied to the Windows target.
FIXME: Could we just remove the target property VERSION in add_llvm_executable() ?

The MacroBlockBegin and MacroBlockEnd options make matching macro identifiers
behave like '{' and '}', respectively, in terms of indentation.
Mozilla code, for example, uses several macros that begin and end a scope.
Previously, Clang-Format removed the indentation resulting in:
MACRO_BEGIN(...)
MACRO_ENTRY(...)
MACRO_ENTRY(...)
MACRO_END
Now, using the options
MacroBlockBegin: "^[A-Z_]+_BEGIN$"
MacroBlockEnd: "^[A-Z_]+_END$"
will yield the expected result:
MACRO_BEGIN(...)
MACRO_ENTRY(...)
MACRO_ENTRY(...)
MACRO_END

not specified, causing regressions.

The Job base class was removed in r241310, so replace a couple of
references to it with Command. Also change another use of Job with
Action, since that's the term used in the source.

Test case trap-fnattr.cpp was failng on clang-ppc64-elf-linux2 because ppc64
sign-extends the i32 return value.
This is a follow-up to r241306.

We had a strange relationship here where we made a list of Jobs
inherit from a single Job, but there weren't actually any places where
this arbitrary nesting was used or needed.
Simplify all of this by removing Job entirely and updating all of the
users to either work with a JobList or a single Command.
