Addresses a conflict with glibc's __nonnull macro by renaming the type
nullability qualifiers as follows:
__nonnull -> _Nonnull
__nullable -> _Nullable
__null_unspecified -> _Null_unspecified
This is the major part of rdar://problem/21530726, but does not yet
provide the Darwin-specific behavior for the old names.

Introduce context-sensitive, non-underscored nullability specifiers
(nonnull, nullable, null_unspecified) for Objective-C method return
types, method parameter types, and properties.
Introduce Objective-C-specific semantics, including computation of the
nullability of the result of a message send, merging of nullability
information from the @interface of a class into its @implementation,
etc .
This is the Objective-C part of rdar://problem/18868820.

Modules builds fundamentally have a non-linear macro history. In the interest
of better source fidelity, represent the macro definition information
faithfully: we have a linear macro directive history within each module, and at
any point we have a unique "latest" local macro directive and a collection of
visible imported directives. This also removes the attendent complexity of
attempting to create a correct MacroDirective history (which we got wrong
in the general case).
No functionality change intended.

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.

It should bring the bots back.
Original messagses:
r227448:
Remove unnecessary default.
r227438:
Fix Index/print-type.cpp test following r227432.
r227432:
libclang: Add three functions useful for dealing with anonymous fields:
clang_Cursor_getOffsetOfField
clang_Cursor_isAnonymous
clang_Type_visitFields
Python: Add corresponding methods for dealing with anonymous fields.

The code building the code completion string for overloads was providing
less detail compared to the one building completion strings for function
declarations. There was no information about optionals and no information
about what's a parameter and what's a function identifier, everything
besides ResultType, CurrentParameter and special characters was classified
as Text.
This makes code completion strings for overload candidates to follow a
pattern very similar, but not identical, to the one in use for function
declarations:
- return type chunk: ResultType
- function identifier chunk: Text
- parameter chunks: Placeholder
- optional parameter chunks: Optional
- current parameter chunk: CurrentParameter
llvm-svn: 227309
The improved completion in call context now works with:
- Functions.
- Member functions.
- Constructors.
- New expressions.
- Function call expressions.
- Template variants of the previous.
There are still rough edges to be fixed:
- Provide support for optional parameters. (fix known)
- Provide support for member initializers. (fix known)
- Provide support for variadic template functions. (fix unknown)
- Others?

prior visible declaration. Prefer to take template parameter names from the
first declaration.
Testcase from a patch by Francisco Lopes!

'class' and 'struct' can be used interchangebly for forward references.
Use the same encoding otherwise we may get into a weird situation where the USR for the same
declaration is different based on whether the definition of the tag reference is visible or not.
llvm-svn: 223632
report the 'init*' invocation as non-dynamic via clang_Cursor_isDynamicCall.
Of course it is dynamic at runtime, but for purposes of indexing we can treat as an invocation to ClassName's init*.

The size of the ID field in CommandInfo was narrow, leading to potential
wrap-around of command IDs, causing misinterpretation later on.
The patch does the following:
- It extends the ID bitfield from 8 to 20 bits.
- It provides a DRY definition of the number of bits for the field to
avoid using literal numbers in different files.
- It introduces a new assertion that checks for the wrap-around.
- It adds the testcase from PR21254.
llvm-svn: 219802
In code-completion, don't assume there is a MacroInfo for everything,
since we aren't serializing the def corresponding to a later #undef in
the same module. Also setup the HadMacro bit correctly for undefs to
avoid an assertion failure.

Predefined decls like 'Protocol' in objc are not loaded from AST files,
so we cannot rely on loading the canonical decl to complete the redecl
chain for redeclarations of these decls. The broken redecl chain was
non-circular, so looping over redecls() would hang.
