Ed Schouten fc79d2ca42 Enable the SafeStack sanitizer on CloudABI by default.
Over the last month we've been testing SafeStack extensively. As far as
we know, it works perfectly fine. That why I'd like to see us having
this enabled by default for CloudABI.

This change introduces a getDefaultSanitizers() function that toolchains
can use to specify which sanitizers are enabled by default. Once all
flags are processed, only flags that had no -fno-sanitize overrides are
enabled.

Extend the thests for CloudABI to test both the default case and the
case in which we want to explicitly disable SafeStack.

Change body autosynthesis to use the BodyFarm-synthesized body even when
an actual body exists. This enables the analyzer to use the simpler,
analyzer-provided body to model the behavior of the function rather than trying
to understand the actual body. Further, this makes the analyzer robust against
changes in headers that expose the implementations of those bodies.

Sean Callanan 8bca996651 Improvements to the ASTImporter to support LLDB top-level Clang expressions.
The testcase for this is in LLDB, adeed by r264662.

This patch adds support for a variety of new expression types to the AST
importer, mostly related to C++.  It also adds support for importing lambdas
correctly, and adds support for importing the attributes attached to any Decl.

Finally, the patch adds a new templated function to ASTNodeImporter that imports
arbitrary arrays of importable things into a bump-allocated array attached to
getToContext().  This is a pattern we see at many places in ASTNodeImporter;
rather than do it slightly differently at each point, this function does it one
way.

Richard Smith 8a3e39ab67 [modules] If both a module file and a module map for the same module are
explicitly provided, and the module map lists a header that does not exist,
unmark the module as 'unavailable' when loading its .pcm file. (Use of the
module might still fail if the relevant headers aren't embedded, but this
behavior is now consistent with how we behave if the module map is not
provided, and with the desired behavior for embedding headers in modules.)

Change the nullability checker to not warn along paths where null is returned from
a method with a non-null return type, even when the diagnostic for this return
has been suppressed. This prevents warning from methods with non-null return types
that inline methods that themselves return nil but that suppressed the diagnostic.

Also change the PreconditionViolated state component to be called "InvariantViolated"
because it is set when a post-condition is violated, as well.

Bob Wilson f43354f69c Check if a path is already absolute before trying to make it so.
The FileSystem::makeAbsolute function has been calculating the current
working directory unconditionally, even when it is not needed. This calls
down to llvm::sys::fs::current_path, which is relatively expensive
because it stats two directories, regardless of whether those paths are
already in the stat cache. The net effect is that when using the
VFS, every stat during header search turns into three stats. With this
change, we get back to a single stat for absolute directory paths.

Faisal Vali a734ab9808 [Cxx1z-constexpr-lambda-P0170R1] Support parsing of constexpr specifier (and its inference) on lambda expressions
Support the constexpr specifier on lambda expressions - and support its inference from the lambda call operator's body.

i.e.
  auto L = [] () constexpr { return 5; };
  static_assert(L() == 5); // OK
  auto Implicit = [] (auto a) { return a; };
  static_assert(Implicit(5) == 5); 

We do not support evaluation of lambda's within constant expressions just yet.

Implementation Strategy:
  - teach ParseLambdaExpressionAfterIntroducer to expect a constexpr specifier and mark the invented function call operator's declarator's decl-specifier with it; Have it emit fixits for multiple decl-specifiers (mutable or constexpr) in this location.
  - for cases where constexpr is not explicitly specified, have buildLambdaExpr check whether the invented function call operator satisfies the requirements of a constexpr function, by calling CheckConstexprFunctionDecl/Body.

Much obliged to Richard Smith for his patience and his care, in ensuring the code is clang-worthy.

Devin Coughlin b8076292ab [analyzer] Add CIFIlter modeling to DeallocChecker.
The -dealloc method in CIFilter is highly unusual in that it will release
instance variables belonging to its *subclasses* if the variable name
starts with "input" or backs a property whose name starts with "input".
Subclasses should not release these ivars in their own -dealloc method --
doing so could result in an over release.

Before this commit, the DeallocChecker would warn about missing releases for
such "input" properties -- which could cause users of the analyzer to add
over releases to silence the warning.

To avoid this, DeallocChecker now treats CIFilter "input-prefixed" ivars
as MustNotReleaseDirectly and so will not require a release. Further, it
will now warn when such an ivar is directly released in -dealloc.

Manman Ren 1c40052646 [ObjCXX] Warn undeclared identifiers.
Instantiation dependence were not being handled correctly for OpqaueValueExpr
AST nodes. As a result, if an undeclared identifier was used in a CXXNewExpr
that is assigned to a ObjC property, there would be no error during parsing, and
there would be a crash during code gen. This patch makes sure that an error
will be issued during parsing in this case.

Before the fix, if CXXNewExpr has a typo, its InstantiationDependent will be
set to true, but if it is wrapped in a OpaqueValueExpr, the OpaqueValueExpr will
not be instantiation dependent, causing the TypoExpr not be to resolved. The fix
propagates InstantiationDependent to OpaqueValueExpr from its SourceExpr. It
also propagates the other instantiation bits.

cleverness.

I left the constructor/destructor checks in CodeGen, because these

NVCC does not support, but which we do.

Since people are going to have to change compiler flags *anyway* in

can pass -D__NVCC__.

Also don't warn about unused flags for the `/Yuh2.h /FIh1.h /FIh2.h`.  The
common case is that the pch was built with `/Ych2.h /FIh1.h /FIh2.h`, so h1.h
is in the PCH, and we shouldn't warn about /FIh1.h not having an effect.
(If we wanted to get fancy, we could store the list of -include flags in the
pch and then check that it matches later on.)

Nico Weber 149d9522fb clang-cl: Include /FI headers in /showIncludes output.
-H in gcc mode doesn't print -include headers, but they are included in
depfiles written by MMD and friends. Since /showIncludes is what's used instead
of depfiles, printing /FI there seems important (and matches cl.exe).

Instead of giving HeaderIncludeGen more options, just switch on ShowAllHeaders
in clang-cl mode and let clang::InitializePreprocessor() not put -include flags
in the <command line> block. This changes the behavior of -E slightly, and it
removes the <command line> flag from the output triggered by setting the
obscure CC_PRINT_HEADERS=1 env var to true while running clang. Both of these
seem ok to change.

George Burgess IV 6da4c20f7d [Sema] Allow implicit conversions of &overloaded_fn in C.
Also includes a minor ``enable_if`` docs update.

Currently, our address-of overload machinery will only allow implicit
conversions of overloaded functions to void* in C. For example:

```
void f(int) __attribute__((overloadable));
void f(double) __attribute__((overloadable, enable_if(0, "")));

void *fp = f; // OK. This is C and the target is void*.
void (*fp2)(void) = f; // Error. This is C, but the target isn't void*.
```

This patch makes the assignment of `fp2` select the `f(int)` overload,
rather than emitting an error (N.B. you'll still get a warning about the
`fp2` assignment if you use -Wincompatible-pointer-types).

Faisal Vali dc6b596ebb [Cxx1z] Implement Lambda Capture of *this by Value as [=,*this] (P0018R3)
Implement lambda capture of *this by copy.
For e.g.:
struct A {

  int d = 10;
  auto foo() { return [*this] (auto a) mutable { d+=a; return d; }; }

};

auto L = A{}.foo(); // A{}'s lifetime is gone.

// Below is still ok, because *this was captured by value.
assert(L(10) == 20);
assert(L(100) == 120);

If the capture was implicit, or [this] (i.e. *this was captured by reference), this code would be otherwise undefined.

Implementation Strategy:
  - amend the parser to accept *this in the lambda introducer
  - add a new king of capture LCK_StarThis
  - teach Sema::CheckCXXThisCapture to handle by copy captures of the
    enclosing object (i.e. *this)
  - when CheckCXXThisCapture does capture by copy, the corresponding 
    initializer expression for the closure's data member 
    direct-initializes it thus making a copy of '*this'.
  - in codegen, when assigning to CXXThisValue, if *this was captured by 
    copy, make sure it points to the corresponding field member, and
    not, unlike when captured by reference, what the field member points
    to.
  - mark feature as implemented in svn

Bruno Cardoso Lopes d878e28e67 Reapply [2] [VFS] Add 'overlay-relative' field to YAML files
This reapplies r261552 and r263748. Fixed testcase to reapply.

The VFS overlay mapping between virtual paths and real paths is done through
the 'external-contents' entries in YAML files, which contains hardcoded paths
to the real files.

When a module compilation crashes, headers are dumped into <name>.cache/vfs
directory and are mapped via the <name>.cache/vfs/vfs.yaml. The script
generated for reproduction uses -ivfsoverlay pointing to file to gather the
mapping between virtual paths and files inside <name>.cache/vfs. Currently, we
are only capable of reproducing such crashes in the same machine as they
happen, because of the hardcoded paths in 'external-contents'.

To be able to reproduce a crash in another machine, this patch introduces a new
option in the VFS yaml file called 'overlay-relative'. When it's equal to
'true' it means that the provided path to the YAML file through the
-ivfsoverlay option should also be used to prefix the final path for every
'external-contents'.

Example, given the invocation snippet "... -ivfsoverlay
<name>.cache/vfs/vfs.yaml" and the following entry in the yaml file:

"overlay-relative": "true",
"roots": [
...
  "type": "directory",
  "name": "/usr/include",
  "contents": [
    {
      "type": "file",
      "name": "stdio.h",
      "external-contents": "/usr/include/stdio.h"
    },
...

Here, a file manager request for virtual "/usr/include/stdio.h", that will map
into real path "/<absolute_path_to>/<name>.cache/vfs/usr/include/stdio.h.

This is a useful feature for debugging module crashes in machines other than
the one where the error happened.

Carlo Bertolli b74bfc80a4 [OPENMP] Implementation of codegen for firstprivate clause of target directive
This patch implements the following aspects:

It extends sema to check that a variable is not reference in both a map clause and firstprivate or private. This is needed to ensure correct functioning at codegen level, apart from being useful for the user.
It implements firstprivate for target in codegen. The implementation applies to both host and nvptx devices.
It adds regression tests for codegen of firstprivate, host and device side when using the host as device, and nvptx side.
Please note that the regression test for nvptx codegen is missing VLAs. This is because VLAs currently require saving and restoring the stack which appears not to be a supported operation by nvptx backend.

It adds a check in sema regression tests for target map, firstprivate, and private clauses.

Steven Watanabe 9359b8fe5d Fix printing of anonymous struct typedefs.
clang -cc1 -ast-print put the struct
definition in the wrong place, like this:

  struct {} typedef S;

The reason that this happens is that the printing code
first prints the struct definition, and then tells the next
declaration to leave out the type. This behavior
is correct for simple variable declarations, but fails for
typedefs (or extern, mutable, etc).

The patch address this problem by skipping the struct
declaration when we first see it, and then telling the first
subsequent declaration that it needs to print out the full
struct definition.

Bruno Cardoso Lopes b76c027717 Reapply [2]: [VFS] Add support for handling path traversals
This was applied twice r261551 and 263617 and later reverted because:

(1) Windows bot failing on unittests. Change the current behavior to do
not handle path traversals on windows.

(2) Windows bot failed to include llvm/Config/config.h in order to use
HAVE_REALPATH. Use LLVM_ON_UNIX instead, as done in lib/Basic/FileManager.cpp.

Handle ".", ".." and "./" with trailing slashes while collecting files
to be dumped into the vfs overlay directory.

Include the support for symlinks into components. Given the path:

/install-dir/bin/../lib/clang/3.8.0/include/altivec.h, if "bin"
component is a symlink, it's not safe to use `path::remove_dots` here,
and `realpath` is used to get the right answer. Since `realpath`
is expensive, we only do it at collecting time (which only happens
during the crash reproducer) and cache the base directory for fast lookups.

Overall, this makes the input to the VFS YAML file to be canonicalized
to never contain traversal components.

Roman Levenstein 35aa5cecf2 Add attributes for preserve_mostcc/preserve_allcc calling conventions to the C/C++ front-end
Till now, preserve_mostcc/preserve_allcc calling convention attributes were only
available at the LLVM IR level. This patch adds attributes for
preserve_mostcc/preserve_allcc calling conventions to the C/C++ front-end.

The code was mostly written by Juergen Ributzka.
I just added support for the AArch64 target and tests.

Olivier Goffart b94ed61452 Fix destructor definition of invalid classes
The declaration of the destructor of an invalid class was not properly marked
as noexcept. As a result, the definition of the same destructor, which was
properly implicitly marked as noexcept, would not match the definition.
This would cause the definition CXXDestructorDecl to be matked as invalid
and omited from the AST.

Mike Spertus 01b14bf761 Add visualizers for more clang types. Create more C++-like visualizations for existing Clang types
Created visualizer for PointerType, LValueReferenceType, RValueReferenceType, and TemplateParmType.
In addition, cleaned up the display of existing types to be more C++-like. For example, instead of

  SubstTemplateTypeParmType: {Identifier (("T"))} => Record (25), {Identifier (("A"))}

it now displays more readably as 

  SubstTemplateTypeParmType: {typename T <= struct A}

The <expand> sections still can be used for all the gory details if necessary.

Vassil Vassilev 632eac3428 [modules] Fix adding a templated friend functions to a namespace from another module.
When clang adds argument dependent lookup candidates, it can perform template
instantiation. For example, it can instantiate a templated friend function and
register it in the enclosing namespace's lookup table.

Marina Yatsina d6d8b315d3 Avoid using LookupResult's implicit copy ctor and assignment operator to avoid warnings
The purpose of this patch is to keep the same functionality without using LookupResult's implicit copy ctor and assignment operator, because they cause warnings when -Wdeprecated is passed.
This patch is meant to help the following review: http://reviews.llvm.org/D18123.
The functionality is covered by the tests in my original commit (255890)
The test case in this patch was added to test a bug caught in the review of the first version of this fix.
