I don't want to rule out the possibility of linking to e.g. interesting
blog posts about uses of Clang, so avoid restricting the content to
"projects".

This breaks URL compatibility, but this document was committed less than

Edwin Vane 2c197e0939 Support in hasDeclaration for types with getDecl()
Using a new metafunction for detecting the presence of the member
'getDecl' in a type T, added support to hasDeclaration for any such type
T. This allows hasDecl() to be replaced and enables several other
subclasses of clang::Type to use hasDeclaration.

Updated unittests and LibASTMatchersReference.html.

John McCall b4a99d3194 Add support for -fvisibility-ms-compat.
We treat this as an alternative to -fvisibility=<?>
which changes the default value visibility to "hidden"
and the default type visibility to "default".

Expose a -cc1 option for changing the default type
visibility, repurposing -fvisibility as the default
value visibility option (also setting type visibility
from it in the absence of a specific option).

David Blaikie 6adc78e0df Replace TypeLoc llvm::cast support to be well-defined.
The TypeLoc hierarchy used the llvm::cast machinery to perform undefined
behavior by casting pointers/references to TypeLoc objects to derived types
and then using the derived copy constructors (or even returning pointers to
derived types that actually point to the original TypeLoc object).

Some context is in this thread:

Though it's spread over a few months which can be hard to read in the mail

Douglas Gregor 6168bd2323 Ensure that the identifier chains have the most recent declaration after module deserialization.
This commit introduces a set of related changes to ensure that the
declaration that shows up in the identifier chain after deserializing
declarations with a given identifier is, in fact, the most recent
declaration. The primary change involves waiting until after we
deserialize and wire up redeclaration chains before updating the
identifier chains. There is a minor optimization in here to avoid
recursively deserializing names as part of looking to see whether
top-level declarations for a given name exist.

A related change that became suddenly more urgent is to property
record a merged declaration when an entity first declared in the
current translation unit is later deserialized from a module (that had
not been loaded at the time of the original declaration). Since we key
off the canonical declaration (which is parsed, not from an AST file)
for emitted redeclarations, we simply record this as a merged
declaration during AST writing and let the readers merge them.

Re-fixes <rdar://problem/13189985>, presumably for good this time.

Daniel Jasper e53beb2647 Improve indentation of builder type calls.
In builder-type calls, it can be very confusing to just indent
parameters from the start of the line. Instead, indent 4 from the
correct function call.

Before:
aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->aaaaaaaaaaaaaaaaaaa( // break
    aaaaaaaaaaaaaa);
aaaaaaaaaaaaaaaaaaaaaaa *aaaaaaaaa = aaaaaa->aaaaaaaaaaaa()->aaaaaaaaaaaaaaaa(
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
    ->aaaaaaaaaaaaaaaaa();

After:
aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->aaaaaaaaaaaaaaaaaaa( // break
                                        aaaaaaaaaaaaaa);

Daniel Jasper 55d7ba6b66 Reformat lines if they were "moved around".
An unwrapped line can get moved around if there is no newline before
it and the previous line was formatted.

Example:

  template<typename T>  // Cursor is on this line when hitting "format"
  T *getFETokenInfo() const { return static_cast<T*>(FETokenInfo); }

"return .." is the second unwrapped line in this scenario. I does not
touch any reformatted region. Thus, the result of formatting is:

  template <typename T> T *getFETokenInfo() const { return static_cast<T *>(FETokenInfo); }

After second format (and arguably desired end-result):

  template <typename T> T *getFETokenInfo() const {
      return static_cast<T *>(FETokenInfo);
  }

This fixes: llvm.org/PR15060.

Saleem Abdulrasool 5f25bc30d1 [CodeGen] tighten objc ivar invariant.load attribution
An ivar ofset cannot be marked as invariant load in all cases.  The ivar offset
is a lazily initialised constant, which is dependent on an objc_msgSend
invocation to perform a fixup of the offset.  If the load is being performed on
a method implemented by the class then this load can safely be marked as an
inviarant because a message must have been passed to the class at some point,
forcing the ivar offset to be resolved.

An additional heuristic that can be used to identify an invariant load would be
if the ivar offset base is a parameter to an objc method.  However, without the
parameters available at hand, this is currently not possible.

John McCall df25c43599 Rework the visibility computation algorithm in preparation
for distinguishing type vs. value visibility.

The changes to the visibility of explicit specializations
are intentional.  The change to the "ugly" test case is
a consequence of a sensible implementation, and I am happy
to argue that this is better behavior.  Other changes may
or may not be intended;  it is quite difficult to divine
intent from some of the code I altered.

I've left behind a comment which I hope explains the
philosophy behind visibility computation.

Jordan Rose 5bc0dd79e1 [analyzer] Don't assert when mixing reinterpret_cast and derived-to-base casts.
This just adds a very simple check that if a DerivedToBase CastExpr is
operating on a value with known C++ object type, and that type is not the
base type specified in the AST, then the cast is invalid and we should
return UnknownVal.

In the future, perhaps we can have a checker that specifies that this is
illegal, but we still shouldn't assert even if the user turns that checker
off.

Jordan Rose 44d877a8c7 [analyzer] Use collectSubRegionKeys to make removeDeadBindings faster.
Previously, whenever we had a LazyCompoundVal, we crawled through the
entire store snapshot looking for bindings within the LCV's region. Now, we
just ask for the subregion bindings of the lazy region and only visit those.

This is an optimization (so no test case), but it may allow us to clean up
more dead bindings than we were previously.

Jordan Rose ba4a6d10e0 [analyzer] Try constant-evaluation for all variables, not just globals.
In C++, constants captured by lambdas (and blocks) are not actually stored
in the closure object, since they can be expanded at compile time. In this
case, they will have no binding when we go to look them up. Previously,
RegionStore thought they were uninitialized stack variables; now, it checks
to see if they are a constant we know how to evaluate, using the same logic
as r175026.

This particular code path is only for scalar variables. Constant arrays and
structs are still unfortunately unhandled; we'll need a stronger solution
for those.

This may have a small performance impact, but only for truly-undefined
local variables, captures in a non-inlined block, and non-constant globals.
Even then, in the non-constant case we're only doing a quick type check.

Daniel Jasper 2457010b1c Remove the trailing whitespace of formatted lines.
So far, clang-format has always assumed the whitespace belonging to the
subsequent token. This has the negative side-effect that when
clang-format formats a line, it does not remove its trailing whitespace,
as it belongs to the next token.

Thus, this patch fixes most of llvm.org/PR15062.

We are not zapping a file's trailing whitespace so far, as this does not
belong to any token we see during formatting. We need to fix this in a
subsequent patch.

Manuel Klimek 2ef908e4e2 An attempt to make the search algorithm easier to understand.
- clear ownership: the SpecificBumpPtrAllocator owns all StateNodes
- this allows us to simplify the memoization data structure into a
  std::set (FIXME: figure out whether we want to use a hash based
  data structure).
- introduces StateNode as recursive data structure, instead of using
  Edge and the Seen-map combined to drill through the graph
- using a count to stabilize the penalty instead of relying on the
  container
- pulled out a method to forward-apply states in the end

This leads to a ~40% runtime decrease on Nico's benchmark.

Main FiXME is that the parameter lists of some function get too long.
I'd vote for either pulling the Queue etc into the Formatter proper,
or creating an inner class just for the search algorithm.

Dmitri Gribenko d1c91f1763 Accept over-qualified constructor in MSVC emulation mode
MSVC accepts this:

  A::A();
};

Clang accepts regular member functions with extra qualification as an MS
extension, but not constructors.  This changes the parser to defer rejecting
qualified constructors so that the same Sema logic can apply to constructors as
regular member functions.  This also improves the error message when MS
extensions are disabled (in my opinion). Before it was:

This redoes how '*' and '&' are classified as pointer / reference markers when

Previously, determineStarAmpUsage() marked a single '*' and '&' followed by
')', '>', or ',' as pointer or reference marker. Now, all '*'s and '&'s
preceding ')', '>', or ',' are marked as pointer / reference markers. Fixes
PR14884.

Since only the last '*' in 'int ***' was marked as pointer before (the rest
were unary operators, which don't reach spaceRequiredBetween()),
spaceRequiredBetween() now had to be thought about handing multiple '*'s in
sequence.

Before:
  return sizeof(int * *);
  Type **A = static_cast<Type * *>(P);

Now:
  return sizeof(int**);
  Type **A = static_cast<Type **>(P);

Nick Lewycky a096b14d1d The meat of this patch is in BuildCXXMemberCalLExpr where we make it use

of callers to MarkFunctionReferenced and DiagnoseUseOfDecl also caused a few
other changes:
 * don't mark functions odr-used when considering them for an initialization
   sequence. Do mark them referenced though.

Lang Hames 5824a4f1b0 When generating IR for default copy-constructors, copy-assignment operators,
move-constructors and move-assignment operators, use memcpy to copy adjacent
POD members.

Previously, classes with one or more Non-POD members would fall back on
element-wise copies for all members, including POD members. This often
generated a lot of IR. Without padding metadata, it wasn't often possible
for the LLVM optimizers to turn the element-wise copies into a memcpy.

This code hasn't yet received any serious tuning. I didn't see any serious
regressions on a self-hosted clang build, or any of the nightly tests, but
I think it's important to get this out in the wild to get more testing.
Insights, feedback and comments welcome.

Douglas Gregor dcf2508791 [Modules] Cope better with top-level declarations loaded after being declared in the current translation unit <rdar://problem/13189985>.
These two related tweaks to keep the information associated with a
given identifier correct when the identifier has been given some
top-level information (say, a top-level declaration) and more
information is then loaded from a module. The first ensures that an
identifier that was "interesting" before being loaded from an AST is
considered to be different from its on-disk counterpart. Otherwise, we
lose such changes when writing the current translation unit as a
module.

Second, teach the code that injects AST-loaded names into the
identifier chain for name lookup to keep the most recent declaration,
so that we don't end up confusing our declaration chains by having a
different declaration in there.

Apple's kernel engineers have been expecting this behavior even though
we've never implemented it before, as far as I can tell. In recent months,
clang has gotten better at using vector instructions to optimize memcpy-like
operations, and that has exposed problems when vector/floating-point
instructions are used in kexts that don't support that. This behavior also
matches what Apple's GCC did for PowerPC targets.

Douglas Gregor 7dab26b87c Ensure that type definitions present in just-loaded modules are
visible.

The basic problem here is that a given translation unit can use
forward declarations to form pointers to a given type, say,

  class X;
  X *x;

and then import a module that includes a definition of X:

  import XDef;

We will then fail when attempting to access a member of X, e.g., 

  x->method()

because the AST reader did not know to look for a default of a class
named X within the new module.

This implementation is a bit of a C-centric hack, because the only
definitions that can have this property are enums, structs, unions,
Objective-C classes, and Objective-C protocols, and all of those are
either visible at the top-level or can't be defined later. Hence, we
can use the out-of-date-ness of the name and the identifier-update
mechanism to force the update.

In C++, we will not be so lucky, and will need a more advanced
solution, because the definitions could be in namespaces defined in
two different modules, e.g.,

  // module 1
  namespace N { struct X; }

  // module 2
  namespace N { struct X { /* ... */ }; }

One possible implementation here is for C++ to extend the information
associated with each identifier table to include the declaration IDs
of any definitions associated with that name, regardless of
context. We would have to eagerly load those definitions.

The missing definition check should be in the same category as the
missing ivar validation - in this case, the intent is to invalidate in
the given class, as described in the declaration, but the implementation
does not perform the invalidation. Whereas the MissingInvalidationMethod
checker checks the cases where the method intention is not to
invalidate. The second checker has potential to have a much higher false
positive rate.

The new annotation allows having methods that only partially invalidate

The checker is going to trust the programmer to call the partial
invalidation method before the invalidator.This is common in cases when
partial object tear down happens before the death of the object.

Tim Northover d3c543703d Improve filechecking of volatile test.
My previous attempt was extremely deficient, allowing more volatiles
to be introduced and not even checking all of the ones that are
present.

This attempt doesn't try to keep track of the values stored or offsets
within particular objects, just that the correct objects are accessed
in a correctly volatile manner throughout.

Jordan Rose 08bf4fd345 CMake: Include Clang unit tests in check-clang target in standalone builds.
Also, remove CLANG_BUILD_TESTS option. It won't have consistent behavior
between standalone and non-standalone builds, so I'm not going to bother
hooking it up for standalone builds. LLVM_BUILD_TESTS will continue to
control unit test inclusion in the "all" target in non-standalone builds.

Finally, fix the default value of CLANG_INCLUDE_TESTS, which was being set
to the boolean value of "LLVM_INCLUDE_TESTS", i.e. OFF, rather than actually
reading the variable ${LLVM_INCLUDE_TESTS}! If you picked up my earlier
commit, YOU WILL HAVE TO MANUALLY SET THIS OPTION BACK ON. My apologies!

Part two of r174691 (allow the unit tests to be built in standalone mode).

Nick Lewycky a245d3e1fc Fix test failure by making sure this file isn't identical to any other file
included in the same test. Clang gets confused about whether it's already built
a module for this file, when running on a content-addressible filesystem.

Jordan Rose dfbe77cdf5 CMake: Optionally allow running the Clang unit tests in standalone builds.
The reason this is not enabled by default is because there is no way for
Clang to guarantee that the LLVM unit testing infrastruture has been built.
However, if it /has/ been built, there's no reason why the standalone Clang
build can't use it!

This should have no effect on existing builds -- in a combined build the
value of the CLANG_INCLUDE_TESTS option defaults to the LLVM equivalent,
and in a standalone build it defaults to off.

Richard Smith 75fc3bf5fe Fix stack overflow and improve performance when a module contains many
overloads of a name by claiming that there are no lookup results for that name
in modules while loading the names from the module. Lookups in deserialization
really don't want to find names which they themselves are in the process of
introducing. This also has the pleasant side-effect of automatically caching
PCH lookups which found no names.

The runtime here is still quadratic in the number of overloads, but the
constant is lower.

Anna Zaks c89ad07d39 [analyzer] Report bugs when freeing memory with offset pointer
The malloc checker will now catch the case when a previously malloc'ed
region is freed, but the pointer passed to free does not point to the
start of the allocated memory. For example:

int *p1 = malloc(sizeof(int));
p1++;
free(p1); // warn

From the "memory.LeakPtrValChanged enhancement to unix.Malloc" entry
in the list of potential checkers.

Anna Zaks acdc13cb00 [analyzer] Add pointer escape type param to checkPointerEscape callback
The checkPointerEscape callback previously did not specify how a
pointer escaped. This change includes an enum which describes the
different ways a pointer may escape. This enum is passed to the
checkPointerEscape callback when a pointer escapes. If the escape
is due to a function call, the call is passed. This changes
previous behavior where the call is passed as NULL if the escape
was due to indirectly invalidating the region the pointer referenced.

Anna Zaks 7c1f408636 [analyzer] Don't reinitialize static globals more than once along a path
This patch makes sure that we do not reinitialize static globals when
the function is called more than once along a path. The motivation is
code with initialization patterns that rely on 2 static variables, where
one of them has an initializer while the other does not. Currently, we
reset the static variables with initializers on every visit to the
function along a path.

ContainerUSR is not really a CXString, but it should own the underlying memory
buffer.  Thus, it is better to change the type to std::string.  This will not
introduce extra copying overhead, since the workaround that is being removed
was already making a copy.
