Alexey Samsonov ac4afe49e7 [Sanitizer] Remove brittle cache variable and slightly simplify blacklisting code.
Now CodeGenFunction is responsible for looking at sanitizer blacklist
(in CodeGenFunction::StartFunction) and turning off instrumentation,
if necessary.

No functionality change.

Alexey Samsonov e7a8ccfaad [Sanitizer] Reduce the usage of sanitizer blacklist in CodeGenModule
Get rid of cached CodeGenModule::SanOpts, which was used to turn off
sanitizer codegen options if current LLVM Module is blacklisted, and use
plain LangOpts.Sanitize instead.

1) Some codegen decisions (turning TBAA or writable strings on/off)
   shouldn't depend on the contents of blacklist.

2) llvm.asan.globals should *always* be created, even if the module
   is blacklisted - soon Clang's CodeGen where we read sanitizer
   blacklist files, so we should properly report which globals are
   blacklisted to the backend.

David Majnemer 611cdb9a63 CodeGen: Cleanup MS ABI RTTI LLVM IR
The MS ABI RTTI emission code would choose names for IR types like
%"MSRTTITypeDescriptor\02".  This name is undesirable because it
requires escaping; the underlying reason for this is that the name is
unprintable.  Fix this by naming it %rtti.TypeDescriptor2.

While here, stop trying to do lookups in the LLVM Module's type table.
Instead, store the IR types in MicrosoftCXXABI.  Lookups by name aren't
particularly fast.

David Majnemer e2cb8d198f CodeGen: Refactor RTTI emission
Let's not expose ABI specific minutia inside of CodeGenModule and Type.
Instead, let's abstract it through CXXABI.

This gets rid of:
CodeGenModule::getCompleteObjectLocator,
CodeGenModule::EmitFundamentalTypeDescriptor{s,},
CodeGenModule::getMSTypeDescriptor,
CodeGenModule::getMSCompleteObjectLocator,
CGCXXABI::shouldRTTIBeUnique,
CGCXXABI::classifyRTTIUniqueness.

CGRTTI was *almost* entirely centered around providing Itanium-style
RTTI information.  Instead of providing interfaces that only it
consumes, move it to the ItaniumCXXABI implementation file.  This allows
it to have access to Itanium-specific implementation details without
providing useless expansion points for the Microsoft ABI side.

Saleem Abdulrasool e700cab4e9 CodeGen: add support for a few MSVC ARM intrinsics

Saleem Abdulrasool 96bfda8dbc CodeGen: add support for MSBuiltin aliases
This completes the infrastructure for the new MSBuiltin aliases in the
instruction definitions.  These behave similar to the GCCBuiltin in that they
can be implicitly constructed without special handling unless needed.

With this change it is possible to annotate an LLVM intrinsic in the backend
instruction definitions and indicate it as a builtin in the Builtin*.def files
in clang via LANGBUILTIN.  That will automatically pass through the instruction
much as a GCCBuiltin.

Note that there is no need for the special handling for ensuring that the
compatibility flag is enabled since the filtering on the LANGBUILTIN will
automatically prevent the intrinsic from bleeding into non-MS compatible
compiler invocations.

David Majnemer 93de4b1608 MS ABI: Get linkage of RTTI data correct
The Itanium rules are not appropriate for the MS ABI.  RTTI data is
_never_ imported and thus is never available_externally.  It is either
internal (if the type's linkage is internal) or linkonce_odr.

This also means that classes which inherit from dllimport'd bases force
their translation unit to duplicate the entirety of the RTTI data of
that base.

Interestingly, the complete object locator can never be referenced by
translation units which import the class.

This fixes PR20106.

Alexey Samsonov 4f319cca42 [ASan] Print exact source location of global variables in error reports.
See https://code.google.com/p/address-sanitizer/issues/detail?id=299 for the
original feature request.

Introduce llvm.asan.globals metadata, which Clang (or any other frontend)
may use to report extra information about global variables to ASan
instrumentation pass in the backend. This metadata replaces
llvm.asan.dynamically_initialized_globals that was used to detect init-order
bugs. llvm.asan.globals contains the following data for each global:
  1) source location (file/line/column info);
  2) whether it is dynamically initialized;
  3) whether it is blacklisted (shouldn't be instrumented).

Source location data is then emitted in the binary and can be picked up
by ASan runtime in case it needs to print error report involving some global.
For example:

  0x... is located 4 bytes to the right of global variable 'C::array' defined in '/path/to/file:17:8' (0x...) of size 40

These source locations are printed even if the binary doesn't have any
debug info.

This is an ABI-breaking change. ASan initialization is renamed to
__asan_init_v4(). Pre-built libraries compiled with older Clang will not work
with the fresh runtime.

David Majnemer f607234fde Driver: Handle /GR- in a compatible way with MSVC
There are slight differences between /GR- and -fno-rtti which made
mapping one to the other inappropriate.

-fno-rtti disables dynamic_cast, typeid, and does not emit RTTI related
information for the v-table.

/GR- does not generate complete object locators and thus will not
reference them in vftables.  However, constructs like dynamic_cast and
typeid are permitted.

This should bring our implementation of RTTI up to semantic parity with
MSVC modulo bugs.

David Majnemer d905da4a5f MS ABI: Reference MSVC RTTI from the VFTable
The pointer for a class's RTTI data comes right before the VFTable but
has no name.  To be properly compatible with this, we do the following:
* Create a single GlobalVariable which holds the contents of the VFTable
  _and_ the pointer to the RTTI data.
* Create a GlobalAlias, with appropriate linkage/visibility, that points
  just after the RTTI data pointer.  This ensures that the VFTable
  symbol will always refer to VFTable data.
* Create a Comdat with a "Largest" SelectionKind and stick the private
  GlobalVariable in it.  By transitivity, the GlobalAlias will be a
  member of the Comdat group.  Using "Largest" ensures that foreign
  definitions without an RTTI data pointer will _not_ be chosen in the
  final linked image.

Whether or not we emit RTTI data depends on several things:
* The -fno-rtti flag implies that we should never not emit a pointer to
  RTTI data before the VFTable.
* __declspec(dllimport) brings in the VFTable from a remote DLL. Use an
  available_externally GlobalVariable to provide a local definition of
  the VFTable.  This means that we won't have any available_externally
  definitions of things like complete object locators.  This is
  acceptable because they are never directly referenced.

To my knowledge, this completes the implementation of MSVC RTTI code
generation.

Further semantic work should be done to properly support /GR-.

Logan Chien e9c8ccbf8f Remove CleanupHackLevel from CGException.
This patch removes the dead code, and refines the
getEHResumeBlock() slightly.

The CleanupHackLevel was a hack to the old exception
handling intrinsics, which have several issues with function
inliner.

Since LLVM 3.0, the new landingpad and resume instructions
are added to LLVM IR.  With the new exception handling
mechanism, most of the issues are fixed now.  We should
always use these instructions to implement the exception
handling code nowadays, and we don't need the hack any more.

Besides, the `CleanupHackLevel` is a compile-time constant,
thus other cases have been considered as dead code for a while.

This removes a const_cast added in r211884 that occurred due to an
inconsistency in how MemoryBuffers are handled between some parts of
clang and LLVM.

MemoryBuffers are immutable and the general convention in the LLVM
project is to omit const from immutable types as it's simply
redundant/verbose (see llvm::Type, for example). While this change
doesn't remove "const" from /every/ MemoryBuffer, it at least makes this

an exception is thrown.  The upshot is that cl.exe /EHs- will compile
try, throw, and catch statements with a warning, but clang-cl will
reject such constructs with a hard error.  We can't compile such EH
constructs anyway, but this may matter to consumers of the AST.

Oliver Stannard 3f32b9be7f [ARM] Fix AAPCS non-compliance caused by very large structs
This is a fix to the code in clang which inserts padding arguments to
ensure that the ARM backend can emit AAPCS-VFP compliant code. This code
needs to track the number of registers which have been allocated in order
to do this. When passing a very large struct (>64 bytes) by value, clang
emits IR which takes a pointer to the struct, but the backend converts this
back to passing the struct in registers and on the stack. The bug was that
this was being considered by clang to only use one register, meaning that
there were situations in which padding arguments were incorrectly emitted
by clang.

Saleem Abdulrasool 4b68a05f3d Driver: use GNU::Link for the Generic_GCC toolchain
This changes the behaviour of the driver for linking to match that of the
Generic_GCC::Assemble.    The default link should use "ld" rather than "gcc" for
the linker as gcc does.  This avoids the unnecessary round-tripping through gcc.
It also is much more reasonable behaviour from the user's perspective.  This
should have been updated with SVN r195554 which changed the behaviour of
Generic_GCC::Assemble.

The gcc_forward test needs to be updated to mark the fact that -march is a flag
for GCC not ld.  This was updated as a typo fix, but added a check for a flag
that is not a link flag.

The bindings test covers the change for testing, and thus no new test was added.

This silences false positives (leaks, use of uninitialized value) in simple
code that uses containers such as std::vector and std::list. The analyzer
cannot reason about the internal invariances of those data structures which

problem, let's just not inline the methods of the containers and allow objects
to escape whenever such methods are called.

This just extends an already existing flag "c++-container-inlining" and applies
the heuristic not only to constructors and destructors of the containers, but
to all of their methods.

Hans Wennborg 9bea9cc73b MS ABI: Propagate class-level DLL attributes to class template specialization bases (PR11170)
Consider the following code:

  template <typename T> class Base {};
  class __declspec(dllexport) class Derived : public Base<int> {}

When the base of an exported or imported class is a class template
specialization, MSVC will propagate the dll attribute to the base.
In the example code, Base<int> becomes a dllexported class.

This commit makes Clang do the proopagation when the base hasn't been
instantiated yet, and warns about it being unsupported otherwise.
This is different from MSVC, which allows changing a specialization
back and forth between dllimport and dllexport and seems to let the
last one win. Changing the dll attribute after instantiation would be
hard for us, and doesn't seem to come up in practice, so I think this
is a reasonable limitation to have.

MinGW doesn't do this kind of propagation.

unconditional jump. This is done by clearing the IRBuilder's
"CurrentDebugLocation"*. If this is not set to some non-empty value
before the cleanup block is emitted, the cleanups don't get a location
either. If a call without a location is emitted in a function with debug
info, and that call is then inlined - bad things happen. (without a
location for the call site, the inliner would just leave the inlined
DebugLocs as they were - pointing to roots in the original function, not
inlined into the current function)

Follow up commit to LLVM will ensure that breaking the invariants of the
DebugLoc chains by having chains that don't lead to the current function
will fail assertions, so we shouldn't accidentally slip any of these
cases in anymore. Those assertions may reveal further cases that need to
be fixed in clang, though I've tried to test heavily to avoid that.

* See r128471, r128513 for the code that clears the
  CurrentDebugLocation. Simply removing this code or moving the code
  into IRBuilder to apply to all unconditional branches would regress
  desired behavior, unfortunately.

Serge Pavlov a826147eef Fix treatment of types defined in function prototype
Types defined in function prototype are diagnosed earlier in C++ compilation.
They are put into declaration context where the prototype is introduced. Later on,
when FunctionDecl object is created, these types are moved into the function context.

This patch fixes PR19018 and PR18963.

Saleem Abdulrasool 702eefed9a Headers: be a bit more careful about inline asm
Conditionally include x86intrin.h if we are building for x86 or x86_64.
Conditionalise definition of inline assembly routines which use x86 or x86_64
inline assembly. This is needed as clang can target Windows on ARM where these
definitions may be included into user code.

Eli Bendersky b198b4e864 Rename loop unrolling and loop vectorizer metadata to have a common prefix.
[Clang part]

These patches rename the loop unrolling and loop vectorizer metadata
such that they have a common 'llvm.loop.' prefix.  Metadata name
changes:

llvm.vectorizer.* => llvm.loop.vectorizer.*
llvm.loopunroll.* => llvm.loop.unroll.*

This was a suggestion from an earlier review
(http://reviews.llvm.org/D4090) which added the loop unrolling
metadata. 

Patch by Mark Heffernan.

David Majnemer 0c43d8077e AST: Initialization with dllimport functions in C
The C++ language requires that the address of a function be the same
across all translation units.  To make __declspec(dllimport) useful,
this means that a dllimported function must also obey this rule.  MSVC
implements this by dynamically querying the import address table located
in the linked executable.  This means that the address of such a
function in C++ is not constant (which violates other rules).

However, the C language has no notion of ODR nor does it permit dynamic
initialization whatsoever.  This requires implementations to _not_
dynamically query the import address table and instead utilize a wrapper
function that will be synthesized by the linker which will eventually
query the import address table.  The effect this has is, to say the
least, perplexing.

Consider the following C program:
__declspec(dllimport) void f(void);

typedef void (*fp)(void);

static const fp var = &f;

const fp fun() { return &f; }

int main() { return fun() == var; }

MSVC will statically initialize "var" with the address of the wrapper
function and "fun" returns the address of the actual imported function.
This means that "main" will return false!

Note that LLVM's optimizers are strong enough to figure out that "main"
should return true.  However, this result is dependent on having
optimizations enabled!

N.B.  This change also permits the usage of dllimport declarators inside
of template arguments; they are sufficiently constant for such a
purpose.  Add tests to make sure we don't regress here.

Zachary Turner 87422d9457 Don't go through the TypeSourceInfo when getting the SourceRange.
VarDecl provides a method getSourceRange(), which provides a more
robust way of getting the SourceRange since the TypeSourceInfo can
be null in certain cases.
