Alexey Samsonov 9b87309a91 [CFI] Diagnose when we CFI in diagnostic mode is unavailable on a toolchain.
Summary:
Namely, we must have proper C++ABI support in UBSan runtime. We don't
have a good way to check for that, so just assume that C++ABI support is
there whenever -fsanitize=vptr is supported (i.e. only on handful of
platforms).

Exact diagnostic is also tricky. It's not "cfi" that is unsupported,
just the diagnostic mode. So, I suggest to report that
"-fno-sanitize-trap=cfi-foobar" is incompatible with a given target
toolchain.

Diego Novillo 5aecacb275 Display profile file name when emitting a file not found diagnostic.
When a profile file cannot be opened, we used to display just the error
message but not the name of the profile the compiler was trying to open.
This will become useful in the next set of patches that introduce
GCC-compatible flags to specify profiles.

Meador Inge f0af05c4a5 [Parse] Allow 'constexpr' in condition declarations
This patch implements the functionality specified by DR948.
The changes are two fold.  First, the parser was modified
to allow 'constexpr's to appear in condition declarations
(which was a hard error before).  Second, Sema was modified
to cleanup maybe odr-used declarations by way of a call to
'ActOnFinishFullExpr'.  As 'constexpr's were not allowed in
condition declarations before the cleanup wasn't necessary
(such declarations were always odr-used).

This fixes PR22491.

Bob Wilson 63c931443d Move the special-case check from r240462 into ARM-specific code.
This fixes a serious bug in r240462: checking the BuiltinID for
ARM::BI_MoveToCoprocessor* in EmitBuiltinExpr() ignores the fact that
each target has an overlapping range of the BuiltinID values. That check
can trigger for builtins from other targets, leading to very bad
behavior.

Part of the reason I did not implement r240462 this way to begin with is
the special handling of the last argument for Neon builtins. In this
change, I have factored out the check to see which builtins have that
extra argument into a new HasExtraNeonArgument() function. There is still
some awkwardness in having to check for those builtins in two separate
places, i.e., once to see if the extra argument is present and once to
generate the appropriate IR, but this seems much cleaner than my previous
patch.

but the corresponding mcr and mcr2 LLVM intrinsics expect that value
to be the third argument. Handle this as a special case, while still
leaving those intrinsics as generic MSBuiltins. I considered the
alternative of handling these in EmitARMBuiltinExpr, but that does
not work well for the follow-up change that I'm going to make to improve
the error handling for PR22560 -- we need the GetBuiltinType() checks
for ICEArguments, and the ARM version of that code is only used for
Neon intrinsics where the last argument is special and not
checked in the normal way.

wherein the constructor call "Compile(args...)" could be misconstrued

Likewise various other methods were not harmonious with their effect,
in that "BuildLinker()" returned a "new namespace::Link(...)"
instead of a "new namespace::Linker(...)" which it now does.

Exceptions: Clang and ClangAs are un-renamed. Those are their rightful names.

David Majnemer c1709d387e [MS ABI] Rework member pointer conversion
Member pointers in the MS ABI are made complicated due to the following:
- Virtual methods in the most derived class (MDC) might live in a
  vftable in a virtual base.
- There are four different representations of member pointer: single
  inheritance, multiple inheritance, virtual inheritance and the "most
  general" representation.
- Bases might have a *more* general representation than classes which
  derived from them, a most surprising result.

We believed that we could treat all member pointers as-if they were a
degenerate case of the multiple inheritance model.  This fell apart once
we realized that implementing standard member pointers using this ABI
requires referencing members with a non-zero vbindex.

On a bright note, all but the virtual inheritance model operate rather
similarly.  The virtual inheritance member pointer representation
awkwardly requires a virtual base adjustment in order to refer to
entities in the MDC.

However, the first virtual base might be quite far from the start of the
virtual base.  This means that we must add a negative non-virtual
displacement.

However, things get even more complicated.  The most general
representation interprets vbindex zero differently from the virtual
inheritance model: it doesn't reference the vbtable at all.

It turns out that this complexity can increase for quite some time:
consider a derived to base conversion from the most general model to the
multiple inheritance model...

To manage this complexity we introduce a concept of "normalized" member
pointer which allows us to treat all three models as the most general
model.  Then we try to figure out how to map this generalized member
pointer onto the destination member pointer model.  I've done my best to
furnish the code with comments explaining why each adjustment is
performed.

This fixes PR23878.

our conversion logical to convert it to the target type.

This allows us to simplify how we think about member pointers because we
don't need to consider non-zero nv adjustments before we even generate
the member pointer.  Furthermore, it gives our adjustment logic more
exposure by utilizing it in a common path.

Alexey Samsonov 7f2a0d2c04 [Sanitizers] Provide better diagnostic for sanitizers unsupported for target triple.
Introduce ToolChain::getSupportedSanitizers() that would return the set
of sanitizers available on given toolchain. By default, these are
sanitizers which don't necessarily require runtime support and are
not toolchain- or architecture-dependent.

Sanitizers (ASan, DFSan, TSan, MSan etc.) which cannot function
without runtime library are marked as supported only on platforms
for which we actually build these runtimes.

This would allow more fine-grained checks in the future: for instance,
we have to restrict availability of -fsanitize=vptr to Mac OS 10.9+
(PR23539).

Update test cases accrodingly: add tests for certain unsupported
configurations, remove test cases for -fsanitize=vptr + PS4
integration, as we don't build the runtime for PS4 at the moment.

This change was first submitted as r239953 and reverted in r239958.
The problem was and still is in Darwin toolchains, which get the
knowledge about target platform too late after initializaition, while
now we require this information when ToolChain::getSanitizerArgs() is
called. r240170 works around this issue.

Summary:
This is unfortunate, but would let us land http://reviews.llvm.org/D10467,
that makes ToolChains responsible for computing the set of sanitizers
they support.

Unfortunately, Darwin ToolChains doesn't know about actual OS they
target until ToolChain::TranslateArgs() is called. In particular, it
means we won't be able to construct SanitizerArgs for these ToolChains
before that.

This change removes SanitizerArgs::needsLTO() method, so that now
ToolChain::IsUsingLTO(), which is called very early, doesn't need
SanitizerArgs to implement this method.

Docs and test cases are updated accordingly. See
https://llvm.org/bugs/show_bug.cgi?id=23539, which describes why we
start all these.

Note that, for performance reasons, this warning will underrepresent

Douglas Gregor b4866e85e5 Diagnose unsafe uses of nil and __nonnull pointers.
This generalizes the checking of null arguments to also work with
values of pointer-to-function, reference-to-function, and block
pointer type, using the nullability information within the underling
function prototype to extend non-null checking, and diagnoses returns
of 'nil' within a function with a __nonnull return type.

Note that we don't warn about nil returns from Objective-C methods,
because it's common for Objective-C methods to mimic the nil-swallowing
behavior of the receiver by checking ostensibly non-null parameters
and returning nil from otherwise non-null methods in that
case.

It also diagnoses (via a separate flag) conversions from nullable to
nonnull pointers. It's a separate flag because this warning can be noisy.

Douglas Gregor 261a89b0f7 Introduce type nullability specifiers for C/C++.
Introduces the type specifiers __nonnull, __nullable, and
__null_unspecified that describe the nullability of the pointer type
to which the specifier appertains. Nullability type specifiers improve
on the existing nonnull attributes in a few ways:
  - They apply to types, so one can represent a pointer to a non-null
    pointer, use them in function pointer types, etc.
  - As type specifiers, they are syntactically more lightweight than
    __attribute__s or [[attribute]]s.
  - They can express both the notion of 'should never be null' and
  also 'it makes sense for this to be null', and therefore can more
  easily catch errors of omission where one forgot to annotate the
  nullability of a particular pointer (this will come in a subsequent
  patch).

Nullability type specifiers are maintained as type sugar, and
therefore have no effect on mangling, encoding, overloading,
etc. Nonetheless, they will be used for warnings about, e.g., passing
'null' to a method that does not accept it.

This is the C/C++ part of rdar://problem/18868820.

Peter Collingbourne d954601f63 CFI: Implement bitset emission for the Microsoft ABI.
Clang's control flow integrity implementation works by conceptually attaching
"tags" (in the form of bitset entries) to each virtual table, identifying
the names of the classes that the virtual table is compatible with. Under
the Itanium ABI, it is simple to assign tags to virtual tables; they are
simply the address points, which are available via VTableLayout. Because any
overridden methods receive an entry in the derived class's virtual table,
a check for an overridden method call can always be done by checking the
tag of whichever derived class overrode the method call.

The Microsoft ABI is a little different, as it does not directly use address
points, and overrides in a derived class do not cause new virtual table entries
to be added to the derived class; instead, the slot in the base class is
reused, and the compiler needs to adjust the this pointer at the call site
to (generally) the base class that initially defined the method. After the
this pointer has been adjusted, we cannot check for the derived class's tag,
as the virtual table may not be compatible with the derived class. So we
need to determine which base class we have been adjusted to.

Specifically, at each call site, we use ASTRecordLayout to identify the most
derived class whose virtual table is laid out at the "this" pointer offset
we are using to make the call, and check the virtual table for that tag.

Because address point information is unavailable, we "reconstruct" it as
follows: any virtual tables we create for a non-derived class receive a tag
for that class, and virtual tables for a base class inside a derived class
receive a tag for the base class, together with tags for any derived classes
which are laid out at the same position as the derived class (and therefore
have compatible virtual tables).

Peter Collingbourne 6708c4a176 Implement diagnostic mode for -fsanitize=cfi*, -fsanitize=cfi-diag.
This causes programs compiled with this flag to print a diagnostic when
a control flow integrity check fails instead of aborting. Diagnostics are
printed using UBSan's runtime library.

The main motivation of this feature over -fsanitize=vptr is fidelity with
the -fsanitize=cfi implementation: the diagnostics are printed under exactly
the same conditions as those which would cause -fsanitize=cfi to abort the
program. This means that the same restrictions apply regarding compiling
all translation units with -fsanitize=cfi, cross-DSO virtual calls are
forbidden, etc.

Peter Collingbourne 9881b78b53 Introduce -fsanitize-trap= flag.
This flag controls whether a given sanitizer traps upon detecting
an error. It currently only supports UBSan. The existing flag
-fsanitize-undefined-trap-on-error has been made an alias of
-fsanitize-trap=undefined.

This change also cleans up some awkward behavior around the combination
of -fsanitize-trap=undefined and -fsanitize=undefined. Previously we
would reject command lines containing the combination of these two flags,
as -fsanitize=vptr is not compatible with trapping. This required the
creation of -fsanitize=undefined-trap, which excluded -fsanitize=vptr
(and -fsanitize=function, but this seems like an oversight).

Now, -fsanitize=undefined is an alias for -fsanitize=undefined-trap,
and if -fsanitize-trap=undefined is specified, we treat -fsanitize=vptr
as an "unsupported" flag, which means that we error out if the flag is
specified explicitly, but implicitly disable it if the flag was implied
by -fsanitize=undefined.

The most general model has fields for the vbptr offset and the vbindex.

Getting this wrong can make member pointer equality fail.

Daniel Jasper ed3f395773 clang-format: [JS] Add a special case for indenting function literals.
Before:
  var func =
      function() {
        doSomething();
      };

After:
  var func =
      function() {
    doSomething();
  };

This is a very narrow special case which fixes most of the discrepency
with what our users do. In the long run, we should try to come up with
a more generic fix for indenting these.
