Summary:
Partial fix for PR26619.
Prior to this change, a DIGlobalVariable corresponding to a static
const was marked with an expression corresponding to its constant
value only if it is of integral type. With this change, we now do the
same if it is of __fp16, float, or double type (that is,
floating-point types that do not exceed 64 bits in size, and hence are
supported easily by the existing LLVM machinery for creating constant
expressions in debug info).

Some functions and templates are treated as __host__ __device__ even
when they don't have explicitly specified target attributes.
What's worse, this treatment may change depending on command line
options (-fno-cuda-host-device-constexpr) or
#pragma clang force_cuda_host_device.
Combined with strict checking for matching function target that comes
with D25809(r288962), it makes it hard to write code which would
explicitly instantiate or specialize some functions regardless of
pragmas or command line options in effect.
This patch changes the way we match target attributes of base template
vs attributes used in explicit instantiation or specialization so that
only explicitly specified attributes are considered. This makes base
template selection behave consistently regardless of pragma of command
line options that may affect CUDA target.

We continue to support dynamic exception specifications in C++1z as an
extension, but produce an error-by-default warning when we encounter one. This
allows users to opt back into the feature with a warning flag, and implicitly
opts system headers back into the feature should they happen to use it.
There is one semantic change implied by P0003R5 but not implemented here:
violating a throw() exception specification should now call std::terminate
directly instead of calling std::unexpected(), but since P0003R5 also removes
std::unexpected() and std::set_unexpected, and the default unexpected handler
calls std::terminate(), a conforming C++1z program cannot tell that we are
still calling it. The upside of this strategy is perfect backwards
compatibility; the downside is that we don't get the more efficient 'noexcept'
codegen for 'throw()'.

llvm-svn: 289005
Summary:
The MSVC toolchain and Clang driver combination currently uses a fairly complex
sequence of steps to determine the MS compatibility version to pass to cc1.
There is some oddness in this sequence currently, with some code which inspects
flags in the toolchain, and some code which inspects the triple and local
environment in the driver code.
This change is an attempt to consolidate most of this logic so that
Win32-specific code lives in MSVCToolChain.cpp. I'm not 100% happy with the
split, so any suggestions are welcome.
There are a few things you might want to watch for for specifically:
- On all platforms, if MSVC compatibility flags are provided (and valid), use
those.
- The fallback sequence should be the same as before, but is now consolidated
into MSVCToolChain::getMSVCVersion:
- Otherwise, try to use the Triple.
- Otherwise, on Windows, check the executable.
- Otherwise, on Windows or with --fms-extensions, default to 18.
- Otherwise, we can't determine the version.
- MSVCToolChain::ComputeEffectiveTriple no longer calls the base
ToolChain::ComputeEffectiveClangTriple. The only thing it would change for
Windows the architecture, which we don't care about for the compatibility
version.
- I'm not sure whether this is philosophically correct (but it should
be easy to add back to MSVCToolChain::getMSVCVersionFromTriple if not).
- Previously, Tools.cpp just called getTriple() anyhow, so it doesn't look
like the effective triple was always being used previously anyhow.

The problem only happen on window ( A MS-ABI issuer )
The nature of the problem is virtual base dtor called more than it is needed after exception throw in inheriting base class(with virtual bases) ctor.
The root problem is when throw happen, not all virtual base classes have been contructed, so not all virtual base dtors are need to call for ehcleanup.
clang has code to handle vbase initialization: basically add check for "complete object flag" before call to v-base ctor.
But that part is missing for cleanup code.
To fix this add similar code as v-base init to cleanup code, same algorithm.
1> Add new routine:
EmitDtorCompleteObjectHandler
With corresponding to EmitCtorCompleteObjectHandler
2> In the EmitDestructorCal
Call EmitDtorCompleteObjectHandler when generate ehcleanup inside ctor.
Just add check for "complete object flag" before call to v-base dtor.

When integrating compilation database output into existing build
systems, two approaches dominate so far. Ad-hoc implementation of the
JSON output rules or using compiler wrappers. This patch adds a new
option "-MJ foo.json" which gives a slightly cleaned up compilation
record. The output is a fragment, i.e. you still need to add the array
markers, but it allows multiple files to be easy merged.
This way the only change in a build system is adding the option with
potentially a per-target output file and merging the files with
something like
(echo '['; cat *.o.json; echo ']' > compilation_database.json
or some additional filtering to remove the trailing comma for strict
JSON compliance.

On a method call, the ObjCGenerics checker uses the type tracked by
DynamicTypePropagation for the receiver to to infer substituted parmeter types
for the called methods and warns when the argument type does not match the
parameter.
Unfortunately, using the tracked type can result in false positives when the
receiver has a non-invariant type parameter and has been intentionally upcast.
For example, becaue NSArray's type parameter is covaraint, the following code
is perfectly safe:
NSArray<NSString *> *allStrings = ...
NSDate *date = ...;
NSArray<NSObject *> *allObjects = allStrings;
NSArray<NSObject *> *moreObjects = [allObjects arrayByAddingObject:date];
but the checker currently warns that the date parameter is not an NSString *.
To avoid this kind of false positive, the checker will now only warn when
the class defining the called method has only invariant type parameters.

latter case, a temporary array object is materialized, and can be

This caused IR generation to stop treating file-scope array compound literals

by modeling such a compound literal as an lvalue. This also improves clang's

This reverts commit r288449.
I believe that this is currently faulty wrt. modules being imported

Makes it break with

However, I believe it should fail with
error: redundant #include of module 'M' appears within namespace 'n'
I have tracked this down to us now inserting a tok::annot_module_begin
instead of a tok::annot_module_include in
Preprocessor::HandleIncludeDirective() and then later in
Parser::parseMisplacedModuleImport(), we hit the code path for
tok::annot_module_begin, which doesn't set FromInclude of

An explicit template specialization can cause the implicit template

chain. Only after having done so do we reference the delayed template
specializations. This allows any implicit specializations which inherit dll

This fixes a bug that was introduced in rL287285. The bug made it
illegal to pass -fsanitize=address during CUDA compilation because the
CudaToolChain class was switched from deriving from the Linux toolchain
class to deriving directly from the ToolChain toolchain class. When
CudaToolChain derived from Linux, it used Linux's getSupportedSanitizers
method, and that method allowed ASAN, but when it switched to deriving
directly from ToolChain, it inherited a getSupportedSanitizers method
that didn't allow for ASAN.
This patch fixes that bug by creating a getSupportedSanitizers method
for CudaToolChain that supports ASAN.
This patch also fixes the test that checks that -fsanitize=address is
passed correctly for CUDA builds. That test didn't used to notice if an
error message was emitted, and that's why it didn't catch this bug when
it was first introduced. With the fix from this patch, that test will
now catch any similar bug in the future.
