Johannes Altmanninger 1a2676924a [analyzer] Make StmtDataCollector customizable
Summary:
This moves the data collection macro calls for Stmt nodes
to lib/AST/StmtDataCollectors.inc

Users can subclass ConstStmtVisitor and include StmtDataCollectors.inc
to define visitor methods for each Stmt subclass. This makes it also
possible to customize the visit methods as exemplified in
lib/Analysis/CloneDetection.cpp.

Move helper methods for data collection to a new module,
AST/DataCollection.

Add data collection for DeclRefExpr, MemberExpr and some literals.

Saleem Abdulrasool 75cfabef35 Headers: give _Unwind_Control_Block double-word alignment
The C++ ABI requires that the exception object (which under AEABI is the
`_Unwind_Control_Block`) is double-word aligned.  The attribute was
applied to the `_Unwind_Exception` type, but not the
`_Unwind_Control_Block`.  This should fix the libunwind test for the
alignment of the exception type.

Nico Weber 699670e764 Implement CFG construction for __try / __except / __leave.
This makes -Wunreachable-code work for programs containing SEH (except for
__finally, which is still missing for now).

__try is modeled like try (but simpler since it can only have a single __except
or __finally), __except is fairly similar to catch (but simpler, since it can't
contain declarations). __leave is implemented similarly to break / continue.

Use the existing addTryDispatchBlock infrastructure (which
FindUnreachableCode() in ReachableCode.cpp uses via cfg->try_blocks_begin()) to
mark things in the __except blocks as reachable.

Re-use TryTerminatedBlock. This means we add EH edges from calls to the __try
block, but not from all other statements. While this is incomplete, it matches
LLVM's SEH codegen support. Also, in practice, BuildOpts.AddEHEdges is always
false in practice from what I can tell, so we never even insert the call EH
edges either.

Summary:
This patch makes the splits emitted for the beginning of comment lines during

non-whitespace content of the line, which messes up further TailOffset

Summary:
This is a patch for clang autocomplete feature.

It will collect values which -analyzer-checker takes, which is defined in
clang/StaticAnalyzer/Checkers/Checkers.inc, dynamically.
First, from ValuesCode class in Options.td, TableGen will generate C++
code in Options.inc. Options.inc will be included in DriverOptions.cpp, and
calls OptTable's addValues function. addValues function will add second
argument to Option's Values class. Values contains string like "foo,bar,.."
which is handed to Values class
in OptTable.

This is the same assertion as in https://reviews.llvm.org/D25206 that is
triggered when RecordLayoutBuilder tries to compute the size of a field
(for capture "typo_boo" in the test case) whose type hasn't been

The fix is to add CorrectDelayedTyposInExpr call to the cases when we
aren't disambiguating between an Obj-C message send and a lambda
expression.

Krasimir Georgiev fe268fc1c8 [clang-format] Break non-trailing block comments
Summary:
This patch is an alternative to https://reviews.llvm.org/D36614, by resolving a
non-idempotency issue by breaking non-trailing comments:

Consider formatting the following code with column limit at `V`:
```
                    V
const /* comment comment */ A = B;
```
The comment is not a trailing comment, breaking before it doesn't bring it under
the column limit. The formatter breaks after it, resulting in:

```
                    V
const /* comment comment */
    A = B;
```
For a next reformat, the formatter considers the comment as a trailing comment,
so it is free to break it further, resulting in:

```
                    V
const /* comment
         comment */
    A = B;
```
This patch improves the situation by directly producing the third case.

Alex Lorenz 34d070f3e5 [ObjC] Check written attributes only when synthesizing ambiguous property
This commit fixes a bug introduced in r307903. The attribute ambiguity checker
that was introduced in r307903 checked all property attributes, which caused
errors for source-compatible properties, like:

@property (nonatomic, readonly) NSObject *prop;
@property (nonatomic, readwrite) NSObject *prop;

because the readwrite property would get implicit 'strong' attribute. The
ambiguity checker should be concerned about explicitly specified attributes
only.

Stephan T. Lavavej 4c30b74390 [Driver] Recognize DevDiv internal builds of MSVC, with a different directory structure.
This is a reasonably non-intrusive change, which I've verified
works for both x86 and x64 DevDiv-internal builds.

The idea is to change `bool IsVS2017OrNewer` into a 3-state
`ToolsetLayout VSLayout`. Either a build is DevDiv-internal,
released VS 2017 or newer, or released VS 2015 or older. When looking at
the directory structure, if instead of `"VC"` we see `"x86ret"`, `"x86chk"`,
`"amd64ret"`, or `"amd64chk"`, we recognize this as a DevDiv-internal build.

After we get past the directory structure validation, we use this knowledge
to regenerate paths appropriately. `llvmArchToDevDivInternalArch()` knows how
we use `"i386"` subdirectories, and `MSVCToolChain::getSubDirectoryPath()`
uses that. It also knows that DevDiv-internal builds have an `"inc"`
subdirectory instead of `"include"`.

This may still not be the "right" fix in any sense, but I believe that it's
non-intrusive in the sense that if the special directory names aren't found,
no codepaths are affected. (`ToolsetLayout::OlderVS` and
`ToolsetLayout::VS2017OrNewer` correspond to `IsVS2017OrNewer` being `false`
or `true`, respectively.) I searched for all references to `IsVS2017OrNewer`,
which are places where Clang cares about VS's directory structure, and the
only one that isn't being patched is some logic to deal with
cross-compilation. I'm fine with that not working for DevDiv-internal builds
for the moment (we typically test the native compilers), so I added a comment.

Fixes D36860.
