aapcs on armv7-ios when the actual ABI is apcs.
Should be no user visible change without -cc1.

Now that TailRecursionElimination has been fixed with r222354, the
threshold on size for lifetime marker insertion can be removed. This
only affects named temporary though, as the patch for unnamed temporaries
is still in progress.

When emitting nested block definitions, the insert-at-point variant of
DIBuilder::insertDeclare() could be called with the insertion point set
to the end-of-BasicBlock sentinel, causing the parent pointer of the
CallInst to be set to the intentionally bogus value of the sentinel.
Fixed by conditionally invoking the correct version of insertDeclare().

Mangling for blocks defined within blocks in an ObjectiveC context were also
broken by SVN r219393. Because the code in mangleName assumed that the code was
either C or C++, we would trigger assertions when trying to mangle the inner
blocks in an ObjectiveC context.
Add a test and use the ObjectiveC specific mangling when dealing with an
ObjectiveC method declaration.

Boostrapping LLVM+Clang+LLDB without threshold on object size for
lifetime markers insertion has shown there was no significant change
in compile time, so let the stack slot colorizer do its optimization
for all slots.

This broke the following gdb tests:
gdb.base__annota1.exp
gdb.base__consecutive.exp
gdb.python__py-symtab.exp
gdb.reverse__consecutive-precsave.exp
gdb.reverse__consecutive-reverse.exp
I will look into this.
This reverts commit 214162.

This allows us to give more precise diagnostics.
Diego kindly tested the impact on debug info size: "The increase on average
debug sizes is 0.1%. The total file size increase is ~0%."

Because references must be initialized using some evaluated expression, they
must point to something, and a callee can assume the reference parameter is
dereferenceable. Taking advantage of a new attribute just added to LLVM, mark
them as such.
Because dereferenceability in addrspace(0) implies nonnull in the backend, we
don't need both attributes. However, we need to know the size of the object to
use the dereferenceable attribute, so for incomplete types we still emit only
nonnull.

for Objective-C metadata to use the new name in various places
where class and protocol names are needed.

This looks like the right way for this check to work, but there is
another semi-obvious bug, I would think: why is CurLoc not zero'd out
between functions? The possibility for it to bleed between them seems
problematic. (& indeed I caused tests to fail when I fixed this a
different way, by setting CurLoc to SourceLocation() and the end of
EmitFunctionEnd... )
The changes to debug-info-blocks.m are due to a mismatch between the
source manager's file naming and CGDebugInfo's default handling when no
-main-file-name is specified. This actually reveals somewhat of a bug in
the debug info when using source files from standard in, too. See the
comment in CGDebugInfo::CreateCompileUnit for more details.
llvm-svn: 208742
This takes a different approach than the
completedType/requiresCompleteType work which relies on AST callbacks to
upgrade the type declaration to a definition. Instead, just defer
constructing the definition to the end of the translation unit.
This works because the definition is never needed by other debug info
(so far as I know), whereas the definition of a struct may be needed by
other debug info before the end of the translation unit (such as
emitting the definition of a member function which must refer to that
member function's declaration).
If we had a callback for whenever an IVar was added to an ObjC interface
we could use that, and remove the need for the ObjCInterfaceCache, which
might be nice. (also would need a callback for when it was more than
just a declaration so we could get properties, etc).
A side benefit is that we also don't need the CompletedTypeCache
anymore. Just rely on the declaration-ness of a type to decide whether
its definition is yet to be emitted.
There's still the PR19562 memory leak, but this should hopefully make
that a bit easier to approach.

and no return expr at the end of the function.
The "function has only simple returns" check in FinishFunction tests
whether the number of simple return exprs equals the number of return
exprs, but so far a fallthrough at the end of a function was not counted
as a return, which would result in cleanup code being associated with the
wrong source line.

This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.
As with the LLVM commit though, we think it'll be more useful for
merging with AArch64 from within the tree.

These tests are logically related, but they're spread about several
different CodeGen directories. Consolidate them in one place to make
them easier to manage.
