CGDebugInfo and DIBuilder were lax in their handling of temporary
MDNodes. All temporary nodes need to be deleted, which means they need
to be RAUW'd with a permanent node. This was not happening.
To ensure this, leverage DIBuilder's new ability to create both
permanent and temporary declarations. Ensure all temporary declarations
are RAUW'd, even with itself. (DIDescriptor::RAUW handles the case where
it is replaced with itself and creates a new, duplicate permanent node
to replace itself with)
This means that all temporary declarations must be added to the
ReplacementMap even if they're never upgraded to definitions - so move
the point of insertion into the map to the point of creation of the
declarations.
llvm-svn: 208055
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.

Items were being redundantly added to the replacement map (both when the
declaration was created, and then again when its definition was
constructed) which caused extra handling to be required when walking the
map (as elements may've already been replaced due to prior entries). By
avoiding adding the duplicates, the checks in the replacement handling
can be replaced with assertions.

Currently, users get error messages about RTTI descriptor mangling with
no useful source location. This addresses that.
Another approach would be to disable C++ exceptions by default in the
driver when using the Microsoft C++ ABI. However, this makes it
impossible to parse system headers that use exception handling
constructs. By delaying the error to IRgen, we can figure out if we
actually need to emit code for this construct. Additionally, users who
are only interested in building refactoring tools on Windows still get a
correct AST without having to add flags. Finally, this is consistent
with what we do for SEH.

destructor conditions to not run through this logic, in which case we can remove
this (marked as FIXME); this currently fixes a crash.
2. Simplify ResolveCondition; while documenting the function, I noticed that it
always returns the last statement - either that statement is the condition
itself (in which case the condition was returned anyway), or the rightmost
leaf is returned; for correctness, the rightmost leaf must be evaluated anyway
(which the CFG does in the last statement), thus we can just return the last
statement in that case, too. Added an assert to verify the invariant.

This patch checks whether the diagnostic options that could lead to
errors (principally -Werror) are consistent between when a module was
built and when it is loaded. If there are new -Werror flags, then the
module is rebuilt. In order to canonicalize the options we do this
check at the level of the constructed DiagnosticsEngine, which contains
the final set of diag to diagnostic level mappings. Currently we only
rebuild with the new diagnostic options, but we intend to refine this in
the future to include the union of the new and old flags, since we know
the old ones did not cause errors. System modules are only rebuilt when
-Wsystem-headers is enabled.
One oddity is that unlike checking language options, we don’t perform
this diagnostic option checking when loading from a precompiled header.
The reason for this is that the compiler cannot rebuild the PCH, so
anything that requires it to be rebuilt effectively leaks into the build
system. And in this case, that would mean the build system
understanding the complex relationship between diagnostic options and
the underlying diagnostic mappings, which is unreasonable. Skipping the
check is safe, because these options do not affect the generated AST.
You simply won’t get new build errors due to changed -Werror options
automatically, which is also true for non-module cases.

Attribute filtering is currently based on a blacklist, which right now includes
all event handler attributes (they contain JavaScipt code). It should be
switched to a whitelist, but going over all of the HTML5 spec requires a
significant amount of time.

definition below all of the header #include lines, clang edition.
If you want more details about this, you can see some of the commits to
Debug.h in LLVM recently. This is just the clang section of a cleanup
I've done for all uses of DEBUG_TYPE in LLVM.

-Wc++11-compat-deprecated-writable-strings. It's neither a C++11 compatibility
warning nor a deprecated feature, it's just ill-formed.
In passing, add that warning to -Wdeprecated, where it belongs.

Summary:
This allows callers of Diags.Report() to append a value to the name of
the flag associated with the diagnostic. This is useful in cases like
the -Rpass flag, where we want the diagnostic to show the name of the
pass that matched the pattern. Instead of showing "... [-Rpass]", this
allows us to show "... [-Rpass=passname]".

parts of Clang. I don't really have any opinion about whether using that
macro is good or bad, but its odd that this is the only one, and Eric
seemed happy with just nuking it for now.

Unlike the standard AAPCS64 ABI, variadic arguments are always passed on the
stack with the Darwin ABI, and this was not being considered when deciding
whether to expand HFA/HVA arguments in a call. An HFA argument with a "float"
base type was being expanded into separate "float" arguments, each of which
was then extended to a double, resulting in a serious mismatch from what is
expected by the va_arg implementation. <rdar://problem/15777067>

Implement Diagnostic::category_name() using clang_getDiagnosticCategoryText()
instead of the deprected clang_getDiagnosticCategoryName().
Preserves existing behaviour and API covered by existing tests.

This test didn't work as intended and was ultimately disabled some years ago in
r169458.
Indeed it's not clear if the '\n' was ever passed through to the driver
correctly given that lit would insert '&& {' at the newline.
Test rewritten to use printf/xargs to insert '\n' in a more reliable manner and
to use FileCheck for verification.

This tests for broad compatibility with platform SDK headers using the clang
driver and so belongs alongside the other header ingtegration tests.

If a module doesn't meet a requirement, neither do its submodules. If we
don't propogate that, we might think it's an error to be missing a
header in one of those submodules.

Unless they are in submodules that aren't available anyway, due to
requirements not being met. Also, mark children as unavailable when the
parent is.

Update clang to use the InstrProfReader from LLVM to read
instrumentation based profile data. This also switches us from the
naive text format to the binary format, since that's what's
implemented in the reader.

This paves the way to making OnDiskHashTable work with hashes that are
not 32 bits wide and to making OnDiskHashTable work very large hash
tables. The LLVM change to use these types is upcoming.
