David Majnemer 4deaac780c MS ABI: Empty pack expansions had their mangling changed in 2013->2015
We used to support the 2013 mangling and changed it to the more
reasonable 2015 mangling.  Let's make the mangling conditional on what
version of MSVC is targeted.

This fixes PR21888.

Richard Smith 7f330cdb31 Make module files passed to a module build via -fmodule-file= available to
consumers of that module.

Previously, such a file would only be available if the module happened to
actually import something from that module.

David Majnemer 5f0dd6162c MS ABI: Emit HandlerMap entries for C++ catch
The HandlerMap describes, to the runtime, what sort of catches surround
the try.  In principle, this structure has to be emitted by the backend
because only it knows the layout of the stack (the runtime needs to know
where on the stack the destination of a copy lives, etc.) but there is
some C++ specific information that the backend can't reason about.

Stick this information in special LLVM globals with the relevant
"const", "volatile", "reference" info mangled into the name.

Reid Kleckner bba3cb95cc MS ABI: Delay default constructor closure checking until the outermost class scope ends
Previously, we would error out on this code because the default argument
wasn't parsed until the end of Outer:

  struct __declspec(dllexport) Outer {
    struct __declspec(dllexport) Inner {
      Inner(void *p = 0);
    };
  };

Now we do the checking on the closing brace of Outer instead of Inner.

really a way to inspect the gcov options from clang to test it here as
well.

Benjamin Kramer 15b9717873 Implement PreprocessingRecord's and LazyVector's iterators on top of iterator_adaptor_base
This basically creates a wrapper around an 'int' that poses as an iterator.
While that looks a bit counter-intuitive it works just fine because iterator
operations and basic integer arithmetic works in exactly the same way.

Remove the manual integer wrapping code and reduce the reliance on iterator
internals in the implementation. No functionality change intended.

Chandler Carruth 0d745bcf66 [modules] Teach the AST reader to handle the case of importing a module
with a subset of the existing target CPU features or mismatched CPU
names.

While we can't check that the CPU name used to build the module will end
up being able to codegen correctly for the translation unit, we actually
check that the imported features are a subset of the existing features.

While here, rewrite the code to use std::set_difference and have it
diagnose all of the differences found.

Test case added which walks the set relationships and ensures we
diagnose all the right cases and accept the others.

No functional change for implicit modules here, just better diagnostics.

Peter Collingbourne d2926c91d5 Implement bad cast checks using control flow integrity information.
This scheme checks that pointer and lvalue casts are made to an object of
the correct dynamic type; that is, the dynamic type of the object must be
a derived class of the pointee type of the cast. The checks are currently
only introduced where the class being casted to is a polymorphic class.

Sanjay Patel 0a6da5de55 [X86, AVX2] Replace inserti128 and extracti128 intrinsics with generic shuffles
This is nearly identical to the v*f128_si256 parts of r231792 and r232052.

AVX2 introduced proper integer variants of the hacked integer insert/extract
C intrinsics that were created for this same functionality with AVX1.

This should complete the front end fixes for insert/extract128 intrinsics.

David Majnemer dfa6d2067c MS ABI: Implement copy-ctor closures, finish implementing throw
This adds support for copy-constructor closures.  These are generated
when the C++ runtime has to call a copy-constructor with a particular
calling convention or with default arguments substituted in to the call.

Because the runtime has no mechanism to call the function with a
different calling convention or know-how to evaluate the default
arguments at run-time, we create a thunk which will do all the
appropriate work and package it in a way the runtime can use.

Using declarations which are aliases to struct types have their name

mangling number to disambiguate it from other anonymous structs in the
same context.

This is a recommit of r231150, reverted in r231409. Turns out
that -fsanitize=shift-base check implementation only works if the

check the base. Make sure that we actually report invalid values
of base or exponent if -fsanitize=shift-base or
-fsanitize=shift-exponent is specified, respectively.

Nico Weber d64657f298 Warn when jumping out of a __finally block via continue, break, return, __leave.
Since continue, break, return are much more common than __finally, this tries
to keep the work for continue, break, return O(1).  Sema keeps a stack of active
__finally scopes (to do this, ActOnSEHFinally() is split into
ActOnStartSEHFinally() and ActOnFinishSEHFinally()), and the various jump
statements then check if the current __finally scope (if present) is deeper
than then destination scope of the jump.

The same warning for goto statements is still missing.
