Justin Bogner 81c22c2fae CodeGen: Handle PGO counters for constructors and destructors

Justin Bogner 0960d091a9 test/CodeGenCXX: Give instr-profile exception tests their own file
This test requires asserts for now, and exception handling has an
awkward structure that leads to extra run lines. Because of this, the
test file's not a great place for other C++ PGO tests, but
instr-profile.cpp is obviously the better name for them.

Richard Smith 8c7bd6ac1a Don't forget about a builtin if we're about to redeclare it and we couldn't
create an implicit declaration of it (because some type it depends on is
unavailable). This had the effect of causing us to not implicitly give it the
right attributes. It turns out that glibc's __sigsetjmp is declared before
sigjmp_buf is declared, and this resulted in us not implicitly giving it
__attribute__((returns_twice)), which in turn resulted in miscompiles in any C
code calling glibc's sigsetjmp.

(See also the vaguely-related sourceware.org/PR4662.)

Aaron Ballman bc909618f2 If an attribute has a semantically meaningful spelling (such as ArgumentWithTypeTagAttr or MSInheritanceAttr), display the spelling used for the attribute as part of the AST dump. This should ease debugging the AST for these attributes. Attributes without semantically meaningful spelling variations are not affected.

Mark Seaborn 74020868ee Handle va_arg on struct types for the le32 target (PNaCl and Emscripten)
PNaCl and Emscripten can both handle va_arg IR instructions with
struct type.

Also add a test to cover generating a va_arg IR instruction from
va_arg in C on le32 (as already handled by VisitVAArgExpr() in
CGExprScalar.cpp), which was not covered by a test before.

(This fixes https://code.google.com/p/nativeclient/issues/detail?id=2381)

Chandler Carruth 902efc61be Teach Clang to look in its installation libdir for libraries (such as
libc++) when the installation is within the system root.

This doesn't really help cross compiles much, but we don't (currently)
have a great story around libc++, cross compiles, and who is responsible
for building and/or installing the libraries. However, it handles the
very common case of non-cross builds in a way entirely consistent with
GCC, so I'm hopeful this won't really hose anyone.

This is the second patch that I think should be backported to 3.4 to
give folks an easy to checkout and install working Clang+libc++
toolchain.

Chandler Carruth 5a3d898758 Make the Linux support for finding libc++ somewhat less braindead.
Now instead of just looking in the system root for it, we also look
relative to the clang binary's directory. This should "just work" in
almost all cases. I've added test cases accordingly.

This is probably *very* worthwhile to backport to the 3.4 branch so that
folks can check it out, build it, and use that as their host compiler
going forward.

Implement type trait primitives used in the latest edition of the Microsoft
standard C++ library type_traits header.

With this change we can parse much of the Visual Studio 2013 standard headers,

Fully implemented, available in all language modes:

 * __is_constructible()
 * __is_nothrow_constructible()
 * __is_nothrow_assignable()

Partially implemented, semantic analysis WIP, available as MS extensions:

 * __is_destructible()
 * __is_nothrow_destructible()

Alp Toker b4bca41491 Fix nothrow trait with multiple default constructors
Check all default ctors, not just the first one we see. This brings
__has_nothrow_constructor() in line with the other unary type traits.

A C++ class can have multiple default constructors but clang was only checking
the first one written, presumably due to ambiguity in the GNU specification.

MSVC has the same bug, while g++ has the correct implementation which we now
match.

This allows the following syntax:

This also extends to Objective-C methods.

The checking logic in Sema is not as clean as I would like.  Effectively
now we need to check both the FunctionDecl/ObjCMethodDecl and the parameters,
so the point of truth is spread in two places, but the logic isn't that
cumbersome.

several first-class attribute syntaxes we support, all of which are
more-or-less equally general.

As discussed on cfe-commits, we may want to revisit this if we start allowing
this syntax as an extension in C (or if C adopts the syntax), but hopefully
this diagnostic wording will be crystal clear to everyone in the mean time.

David Majnemer 37054dd4e7 MS ABI: Improve selection of an inheritance model
The MSVC ABI is rather finicky about the exact representation of it's
pointer-to-member representation.  The exact position of when and where
it will go with one representation versus another appears to be when it
desires the pointer-to-member to be complete.

To properly implement this in clang, do several things:
- Give up on tracking the polymorphic nature of the class.  It isn't
  useful to Sema and is only pertinent when choosing CodeGen-time
  details like whether the field-offset can be 0 instead of -1.
- Insist on locking-in the inheritance model when we ask our
  pointer-to-member type to be complete.  From there, grab the
  underlying CXXRecordDecl and try to make *that* complete.  Once we've
  done this, we can calculate it's inheritance model and apply it using

N.B. My first bullet point is a lie.  We will eventually care about the

David Majnemer f5b93794b7 Sema: Fix crash during member pointer conversion involving incomplete classes
We would attempt to determine the inheritance relationship between
classes 'A' and 'B' during static_cast if we tried to convert from 'int
A::*' to 'int B::*'.  However, the question "does A derive from B" is
not meaningful when 'A' isn't defined.

Handle this case by requiring that 'A' be defined.

Evgeniy Stepanov d04b861e69 [asan] Remove -fsanitize-address-zero-base-shadow command line
flag from clang, and disable zero-base shadow support on all platforms
where it is not the default behavior.

- It is completely unused, as far as we know.
- It is ABI-incompatible with non-zero-base shadow, which means all
objects in a process must be built with the same setting. Failing to
do so results in a segmentation fault at runtime.
- It introduces a backward dependency of compiler-rt on user code,
which is uncommon and complicates testing.

Chandler Carruth b653131345 Move a bunch of tests to directly use the CC1 layer. This at least saves
a subprocess invocation which is pretty significant on Windows. It also
likely saves a bunch of thrashing the host machine needlessly. Finally
it makes the tests much more predictable and less dependent on the host.
For example 'header_lookup1.c' was passing '-fno-ms-extensions' just to
thwart the host detection adding it into the compilation. By runnig CC1
directly we don't have to deal with such oddities.

Chandler Carruth f9814063c6 Switch this test from needlessly running the clang driver to directly
test the CC1 layer.

This actually uncovered that the test semes to no longer be passing for
the reasons intended. =[ The name of the test would lead me to believe
that it should be testing the semantics of noreturn in the static
analyzer.... but there are in fact no -verify assertions about noreturn
that i can find. And the noreturn checker is no longer in 'alpha.core'.
It is in 'core.builtins'. The test *does* have one assertion for a null
dereference warning. This *also* isn't in 'alpha.core', but the driver
inserts a pile of other checker packages, including 'core' which has
this warning.

So I have switch the RUN line to actually do the minimal thing that this
test currently exercises, but someone who works on the static analyzer
should probably look at this and either nuke it or move it to actually
check the noreturn behavior.

This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,

To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

Jordan Rose c9176072e6 [analyzer] Add a CFG node for the allocator call in a C++ 'new' expression.
In an expression like "new (a, b) Foo(x, y)", two things happen:
- Memory is allocated by calling a function named 'operator new'.
- The memory is initialized using the constructor for 'Foo'.

Currently the analyzer only models the second event, though it has special
cases for both the default and placement forms of operator new. This patch
is the first step towards properly modeling both events: it changes the CFG
so that the above expression now generates the following elements.

1. a
2. b
3. (CFGNewAllocator)
4. x
5. y
6. Foo::Foo

The analyzer currently ignores the CFGNewAllocator element, but the next
step is to treat that as a call like any other.

The CFGNewAllocator element is not added to the CFG for analysis-based
warnings, since none of them take advantage of it yet.

If we end up needing to define an implicit destructor, we don't skip

of generating the destructor definition, and aren't affected by which TU
the check is performed in.

...by synthesizing their body to be "return self->_prop;", with an extra
nudge to RetainCountChecker to still treat the value as +0 if we have no
other information.

This doesn't handle weak properties, but that's mostly correct anyway,
since they can go to nil at any time. This also doesn't apply to properties
whose implementations we can't see, since they may not be backed by an
ivar at all. And finally, this doesn't handle properties of C++ class type,
because we can't invoke the copy constructor. (Sema has actually done this
work already, but the AST it synthesizes is one the analyzer doesn't quite
handle -- it has an rvalue DeclRefExpr.)

Modeling setters is likely to be more difficult (since it requires
handling strong/copy), but not impossible.

Warren Hunt 640015cbc3 [ms-abi] Fixing CGRecordLayoutBuilder w.r.t. MS NonVirutalBase Layout
The MS abi lays out *all* non-virtual bases with leading vfptrs before 
laying out non-virutal bases without vfptrs.  This guarantees that the 
primary base is laid out first.  r198818 fixed RecordLayoutBuilder to 
produce compatiable layouts.  This patch fixes CGRecordLayoutBuilder to 
be able to consume those layouts and produce meaningful output without 
tripping any asserts about assumed incoming layout.

A test case is included that shows CGRecordLayoutBuilder in fact 
produces output in the compatiable order.

The only plugins available for use in testing are the examples, so plugin tests

(The examples should really be enabled by default, not just to aid testing but
also to prevent bitrot in some key user-facing code. I'll propose that
shortly.)

Reid Kleckner 5f08094106 [ms-cxxabi] Improve vbtable name mangling accuracy
Summary:
This makes us more compatible with MSVC 2012+ and fixes PR17748 where we
would give two tables the same name.

Rather than doing a fresh depth-first traversal of the inheritance graph
for every record's vbtables, now we memoize vbtable paths for each
record.  By doing memoization, we end up considering virtual bases of
subobjects that come later in the depth-first traversal.  Where
previously we would have ignored a virtual base that we'd already seen,
we now consider it for name mangling purposes without emitting a
duplicate vbtable for it.
