Akira Hatanaka ad51539597 [Sema][ObjC] Check whether a variable has a definition, rather than
checking its storage class, when determining whether casting a C pointer
to an ObjC pointer is allowed.

This change allows casting variables whose declarations are directly
contained in a linkage specification to an ObjC pointer type. Those
variables are treated as if they contain the extern specifier for the
purpose of determining whether they are definitions or not.

Richard Trieu fd1acbb9bb [ODRHash] Improve handling of hash values
Calculating the hash in Sema::ActOnTagFinishDefinition could happen before
all sub-Decls were parsed or processed, which would produce the wrong hash
value.  Change to calculating the hash on the first use and storing the value
instead.  Also, avoid using the macros that were only for Boolean fields and
use an explicit checker during the DefintionData merge.  No functional change,
but was this blocking other ODRHash patches.

Anna Thomas 00dc1b74b7 [LV] Avoid vectorizing first order recurrence when phi uses are outside loop
In the vectorization of first order recurrence, we vectorize such
that the last element in the vector will be the one extracted to pass into the
scalar remainder loop. However, this is not true when there is a phi (other
than the primary induction variable) is used outside the loop.
In such a case, we need the value from the second last iteration (i.e.
the phi value), not the last iteration (which would be the phi update).
I've added a test case for this. Also see PR32396.

A follow up patch would generate the correct code gen for such cases,
and turn this vectorization on.

David Blaikie e6b7c28d17 Modular Codegen: Add/use a bit in serialized function definitions to track whether they are the subject of modular codegen
Some decls are created not where they are written, but in other module
files/users (implicit special members and function template implicit
specializations). To correctly identify them, use a bit next to the definition
to track the modular codegen property.

Discussed whether the module file bit could be omitted in favor of
reconstituting from the modular codegen decls list - best guess today is that
the efficiency improvement of not having to deserialize the whole list whenever
any function is queried by a module user is worth it for the small size
increase of this redundant (list + bit-on-def) representation.

Francis Ricci 84f17f32ad Don't delete lsan thread-local data until it's no longer required
Summary:
The routines for thread destruction in the thread registry require
the lsan thread index, which is stored in pthread tls on OS X.
This means that we need to make sure that the lsan tls isn't destroyed
until after the thread registry tls. This change ensures that we
don't delete the lsan tls until we've finished destroying the thread
in the registry, ensuring that the destructor for the lsan tls runs
after the destructor for the thread registry tls.

This patch also adds a check to ensure that the thread ID is valid before
returning it in GetThreadID(), to ensure that the above behavior
is working correctly.

Sean Callanan b7160ca466 [clang-import-test] Lookup inside contexts
clang-import-test has until now been only able to report top-level Decls.
This is clearly insufficient; we should be able to look inside structs 
and namespaces also.  This patch adds new test cases for a variety of 
lookups inside existing ASTContexts, and adds the functionality necessar
to make most of these testcases work.  (One testcase is known to fail 
because of ASTImporter limitations when importing templates; I'll look 
into that separately.)

This patch also separates the core functionality out into 
ExternalASTMerger, an interface that allows clients like LLDB to make 
use of it.  clang-import-test now only has the machinery necessary to
set up the tests.

Evandro Menezes 203eef0ed5 [AArch64] Simplify MacroFusion
This patch assumes that the dependents to be scanned for the ExitSU are its
predecessors; otherwise, the successors of the instr are scanned.

Furthermore, sometimes the ExitSU was being fused twice, since it may be
fused once when scanning the successors from the beginning of the BB and
then again when scanning the predecessors of ExitSU.  Thus, when scanning
the successors of an instr, skip the ExitSU.

Andrea Di Biagio 8e26936bfd [AddDiscriminators] Assign discriminators to MemIntrinsic calls.
Before this patch, pass AddDiscriminators always avoided to assign
discriminators to intrinsic calls. This was done mainly for two reasons:
 1) We wanted to minimize the number of based discriminators used.
 2) We wanted to avoid non-deterministic discriminator assignment for
    different debug levels.

Unfortunately, that approach was problematic for MemIntrinsic calls.
MemIntrinsic calls can be split by SROA into loads and stores, and each new
load/store instruction would obtain the debug location from the original
intrinsic call.
If we don't assign a discriminator to MemIntrinsic calls, then we cannot
correctly set the discriminator for the newly created loads and stores.
This may have a negative impact on the basic block weight computation
performed by the SampleLoader.

This patch fixes the issue by letting MemIntrinsic calls have a discriminator.

Move LTO::run() to a "run" subcommand so that we can introduce new subcommands
for testing different parts of the LTO implementation.

This doesn't use llvm::cl subcommands because it doesn't appear to be currently
possible to pass an argument not associated with a subcommand to a subcommand
(e.g. -lto-use-new-pm, -mcpu=yonah).

Yaxun Liu b34ec829be [OpenCL] Map default address space to alloca address space
For OpenCL, the private address space qualifier is 0 in AST. Before this change, 0 address space qualifier
is always mapped to target address space 0. As now target private address space is specified by
alloca address space in data layout, address space qualifier 0 needs to be mapped to alloca addr space specified by the data layout.

This change has no impact on targets whose alloca addr space is 0.
