Davide Italiano da8a3b903b [Sema] main can't be declared as global variable, in C++.
So, we now reject that. We also warn for any external-linkage global
variable named main in C, because it results in undefined behavior.

Alexey Bataev b08f89ffc1 [OPENMP] Fix for http://llvm.org/PR24371: Assert failure compiling blender 2.75.
blender uses statements expression in condition of the loop under control of the '#pragma omp parallel for'. This condition is used several times in different expressions required for codegen of the loop directive. If there are some variables defined in statement expression, it fires an assert during codegen because of redefinition of the same variables.
We have to rebuild several expression to be sure that all variables are unique.

Manuel Klimek 54042e743c Add structed way to express command line options in the compilation database.
Currently, arguments are passed via the string attribute 'command',
assuming a shell-escaped / quoted command line to extract the original
arguments. This works well enough on Unix systems, but turns out to be
problematic for Windows tools to generate.

This CL adds a new attribute 'arguments', an array of strings, which
specifies the exact command line arguments. If 'arguments' is available
in the compilation database, it is preferred to 'commands'.

Currently there is no plan to retire 'commands': there are enough
different use cases where users want to create their own mechanism for
creating compilation databases, that it doesn't make sense to force them
all to implement shell command line parsing.

Patch by Daniel Dilts.

Richard Smith fb1e7f7d1a [modules] Add an experimental -cc1 feature to embed the contents of an input
file in the .pcm files. This allows a smaller set of files to be sent to a
remote build worker when building with explicit modules (for instance, module
map files need not be sent along with the corresponding precompiled modules).

This doesn't actually make the embedded files visible to header search, so
it's not useful as a packaging format for public header files.

David Blaikie 86d8cf3502 unique_ptrify ConsumedBlockInfo analysis to make it move assignable
ConsumedBlockInfo objects were move assigned, but only in a state where
the dtor was a no-op anyway. Subtle and easily could've happened in ways
that wouldn't've been safe - so this change makes it safe no matter what

David Majnemer 2dcef9e0a4 Avoid iteration invalidation issues around MaterializedTemporaryExpr
We risk iterator invalidation issues if we use a DenseMap to hold the
backing storage for an APValue.  Instead, BumpPtrAllocate them and
use APValue * as our DenseMap value.

Also, don't assume that MaterializedGlobalTemporaryMap won't regrow
between when we initially perform a lookup and later on when we actually
try to insert into it.

This fixes PR24289.

Partly addressed by r244843, but the explicit dtor in LambdaScopeInfo

function from LambdaScopeInfo unfortunately, but it seems neater than
having to explicitly default any special members LambdaScopeInfo needs.

Richard Smith 216a3bd70d [modules] Change the way we deal with .d output for explicitly-specified module
files: include the .pcm file itself in the .d output, rather than including its
own input files. Other forms of module file continue to be transparent for .d
output.

Arguably, the input files for the .pcm file are still inputs to the
compilation, but that's unnecessary for make-like build systems (where the
mtime of the .pcm file is sufficient) and harmful for smarter build systems
that know about module files and want to track only the local dependencies.

Ben Langmuir 7ff29148ac [Modules] Add Darwin-specific compatibility module map parsing hacks
This preserves backwards compatibility for two hacks in the Darwin
system module map files:

1. The use of 'requires excluded' to make headers non-modular, which
should really be mapped to 'textual' now that we have this feature.

2. Silently removes a bogus cplusplus requirement from IOKit.avc.

Once we start diagnosing missing requirements and headers on

SDKs.

Summary:
Clang sanitizers, such as AddressSanitizer, ThreadSanitizer, MemorySanitizer,
Control Flow Integrity and others, use blacklists to specify which types / functions
should not be instrumented to avoid false positives or suppress known failures.

This change adds the blacklist filenames to the list of dependencies of the rules,

Mark Heffernan 397a98d86d Add new llvm.loop.unroll.enable metadata for use with "#pragma unroll".
This change adds the new unroll metadata "llvm.loop.unroll.enable" which directs
the optimizer to unroll a loop fully if the trip count is known at compile time, and
unroll partially if the trip count is not known at compile time. This differs from
"llvm.loop.unroll.full" which explicitly does not unroll a loop if the trip count is not
known at compile time

With this change "#pragma unroll" generates "llvm.loop.unroll.enable" rather than
"llvm.loop.unroll.full" metadata. This changes the semantics of "#pragma unroll" slightly
to mean "unroll aggressively (fully or partially)" rather than "unroll fully or not at all".

The motivating example for this change was some internal code with a loop marked
with "#pragma unroll" which only sometimes had a compile-time trip count depending
on template magic. When the trip count was a compile-time constant, everything works
as expected and the loop is fully unrolled. However, when the trip count was not a
compile-time constant the "#pragma unroll" explicitly disabled unrolling of the loop(!).
Removing "#pragma unroll" caused the loop to be unrolled partially which was desirable
from a performance perspective.

would just derive ASTContext from llvm::AllocatorBase, but that does
not work because ASTContext's allocator is mutable and we allocate using

Ulrich Weigand 3c5038a535 Add support for System z vector language extensions
The z13 vector facility has an associated language extension,
closely modeled on AltiVec/VSX.  The main differences are:

- vector long, vector float and vector pixel are not supported

- vector long long and vector double are supported (like VSX)

- comparison operators return a vector rather than a scalar integer

- shift operators behave like the OpenCL shift operators

- vector bool is only supported as argument to certain operators;
  some operators allow mixing a bool with a non-bool vector 

This patch adds clang support for the extension.  It is closely modelled
on the AltiVec support.  Similarly to the -faltivec option, there's a
new -fzvector option to enable the extensions (as well as an -mzvector
alias for compatibility with GCC).  There's also a separate LangOpt.

The extension as implemented here is intended to be compatible with
the -mzvector extension recently implemented by GCC.

Based on a patch by Richard Sandiford.

Nico Weber cee4d85faf Split -Wmicrosoft into many specific warnings.
Also move "pragma comment" warning from -Wmicrosoft to -Wignored-pragmas.

-Wmicrosoft currently covers many different areas, some more useful than
others.  Split it into many targeted flags, so that projects can choose to
enable only a subset of these warnings.  This is also useful for incrementally
fixing and turning on these warnings.

-Wno-microsoft still disables all these warnings, and -Wmicrosoft still enables
them all.  After this change, it's possible to pass `-Wno-microsoft
-Wmicrosoft-unqualified-friend` to only enable -Wmicrosoft-unqualified-friend,
and `-Wmicrosoft -Wno-microsoft-unqualified-friend` to enable all other
Microsoft warnings.

I put all the template-related warnings behind -Wmicrosoft-template; if that
turns out to be too coarse we can make that finer later on. (In practice, I
haven't seen the template-related warnings fire frequently.)

David Majnemer 51fd8a020b [MS Compat] Allow _Atomic(Type) and 'struct _Atomic' to coexist
MSVC 2013 ships, as part of its STL implementation, a class named
'_Atomic'.  This is unfortunate because this keyword is in conflict with
the C11 keyword with the same name.  Our solution was to disable this
keyword when targeting MSVC 2013 and reenable it for 2015.

However, this makes it impossible for clang's headers to make use of
_Atomic.  This is problematic in the case of libc++ as it makes heavy
use of this keyword.

Let the keywordness of _Atomic float under certain circumstances:
the body of a class named _Atomic, or a class with a base specifier
named _Atomic, will not have the keyword variant of _Atomic for the
duration of the class body.  This is sufficient to allow us to correctly
handle _Atomic in the STL while permitting us to use _Atomic as a
keyword everywhere else.

Bob Wilson 7c73083bd3 Ignore the "novtable" declspec when not using the Microsoft C++ ABI.
Clang used to silently ignore __declspec(novtable). It is implemented
now, but leaving the vtable uninitialized does not work when using the
Itanium ABI, where the class layout for complex class hierarchies is
stored in the vtable. It might be possible to honor the novtable
attribute in some simple cases and either report an error or ignore
it in more complex situations, but it’s not clear if that would be
worthwhile. There is also value in having a simple and predictable
behavior, so this changes clang to simply ignore novtable when not using
the Microsoft C++ ABI.

Benjamin Kramer 5733e3512b [AST] Remove StmtRange in favor of an iterator_range.
StmtRange was just a convenient wrapper for two StmtIterators before
we had real range support. This removes some of the implicit conversions
StmtRange had leading to slightly more verbose code but also should make
more obvious what's going on. No functional change intended.

- Clean up users of magic dereferencing. The iterator should behave like an Expr **.

Steven Wu 546a19628b Fix -save-temp when using objc-arc, sanitizer and profiling
Currently, -save-temp will cause ObjCARC optimization to be dropped,
sanitizer pass to run early in the pipeline, and profiling
instrumentation to run twice.
Fix the issue by properly disable all passes in the optimization
pipeline when generating bitcode output and parse some of the Language
Options even when the input is bitcode so the passes can be setup
correctly.

James Y Knight 53c7616e2e Fix alignment issues in Clang.
Some const-correctness changes snuck in here too, since they were in the
area of code I was modifying.

This seems to make Clang actually work without Bus Error on
32bit-sparc.

Follow-up patches will factor out a trailing-object helper class, to
make classes using the idiom of appending objects to other objects
easier to understand, and to ensure (with static_assert) that required
alignment guarantees continue to hold.

NOTE: reverts r242077 to reinstate r242058, r242065, 242067

  - Added a test for cuda pipeline creation in clang driver.

  New clang options:
  --cuda-host-only   - Do host-side compilation only.
  --cuda-device-only - Do device-side compilation only.

  --cuda-gpu-arch=<ARCH> - specify GPU architecture for device-side
    compilation. E.g. sm_35, sm_30. Default is sm_20. May be used more
    than once in which case one device-compilation will be done per

Diego Novillo 578caf5da7 Add GCC-compatible flags -fprofile-generate and -fprofile-use.
This patch adds support for specifying where the profile is emitted in a
way similar to GCC. These flags are used to specify directories instead
of filenames. When -fprofile-generate=DIR is used, the compiler will
generate code to write to <DIR>/default.profraw.

The patch also adds a couple of extensions: LLVM_PROFILE_FILE can still be
used to override the directory and file name to use and -fprofile-use
accepts both directories and filenames.

To simplify the set of flags used in the backend, all the flags get
canonicalized to -fprofile-instr-{generate,use} when passed to the
backend. The decision to use a default name for the profile is done
in the driver.

Yaron Keren 45a5bfef44 Add clang_free to libclang to free memory allocated in libclang.
One of the problems libclang tests has running under Windows is memory
allocated in libclang.dll but being freed in the test executable, possibly
by a different memory manager. This patch exposes a new export function,
clang_free(), used to free any allocated memory with the same libclang.dll
memory manager that allocated the memory.

Douglas Gregor ab7f0b342f The AST importer had a bug where it would enter into an infinite recursion
when importing type parameter lists.  The reason is that type parameters
have their DeclContexts set to the interface that is parameterized with those
types, and the importer would follow that loop and blow the stack out.

I've changed the way this works so that the type parameters are only imported
after the interface that contains them has been registered via the Imported()
function.

This is tested by LLDB.

Foundation collections.

Douglas Gregor 10dc9d80cb Warn when an intended Objective-C specialization was actually a useless protocol qualification.
Warn in cases where one has provided redundant protocol qualification
that might be a typo for a specialization, e.g., NSArray<NSObject>,
which is pointless (NSArray declares that it conforms to NSObject) and
is likely to be a typo for NSArray<NSObject *>, i.e., an array of
NSObject pointers. This warning is very narrow, only applying when the
base type being qualified is parameterized, has the same number of
parameters as their are protocols listed, all of the names can also
refer to types (including Objective-C class types, of course), and at
least one of those types is an Objective-C class (making this a typo
for a missing '*'). The limitations are partly for performance reasons
(we don't want to do redundant name lookup unless we really need to),
and because we want the warning to apply in very limited cases to
limit false positives.

protocol qualifiers from the declaration specifiers, which never
really made sense: instead, provide Sema entry points to make them
part of the type annotation token. Among other things, this properly
diagnoses bogus types such as "<NSCopying> id" which should have been
written as "id <NSCopying>".

Douglas Gregor e83b95641f Substitute type arguments into uses of Objective-C interface members.
When messaging a method that was defined in an Objective-C class (or
category or extension thereof) that has type parameters, substitute
the type arguments for those type parameters. Similarly, substitute
into property accesses, instance variables, and other references.

This includes general infrastructure for substituting the type
arguments associated with an ObjCObject(Pointer)Type into a type
referenced within a particular context, handling all of the
substitutions required to deal with (e.g.) inheritance involving
parameterized classes. In cases where no type arguments are available
(e.g., because we're messaging via some unspecialized type, id, etc.),
we substitute in the type bounds for the type parameters instead.

Example:

  @interface NSSet<T : id<NSCopying>> : NSObject <NSCopying>
  - (T)firstObject;
  @end

  void f(NSSet<NSString *> *stringSet, NSSet *anySet) {
    [stringSet firstObject]; // produces NSString*
    [anySet firstObject]; // produces id<NSCopying> (the bound)
  }

When substituting for the type parameters given an unspecialized
context (i.e., no specific type arguments were given), substituting
the type bounds unconditionally produces type signatures that are too
strong compared to the pre-generics signatures. Instead, use the
following rule:

  - In covariant positions, such as method return types, replace type
    parameters with “id” or “Class” (the latter only when the type
    parameter bound is “Class” or qualified class, e.g,
    “Class<NSCopying>”)
  - In other positions (e.g., parameter types), replace type
    parameters with their type bounds.
  - When a specialized Objective-C object or object pointer type
    contains a type parameter in its type arguments (e.g.,
    NSArray<T>*, but not NSArray<NSString *> *), replace the entire
    object/object pointer type with its unspecialized version (e.g.,
    NSArray *).

Douglas Gregor e9d95f1ecc Handle Objective-C type arguments.
Objective-C type arguments can be provided in angle brackets following
an Objective-C interface type. Syntactically, this is the same
position as one would provide protocol qualifiers (e.g.,
id<NSCopying>), so parse both together and let Sema sort out the
ambiguous cases. This applies both when parsing types and when parsing
the superclass of an Objective-C class, which can now be a specialized
type (e.g., NSMutableArray<T> inherits from NSArray<T>).

Check Objective-C type arguments against the type parameters of the
corresponding class. Verify the length of the type argument list and
that each type argument satisfies the corresponding bound.

Specializations of parameterized Objective-C classes are represented
in the type system as distinct types. Both specialized types (e.g.,
NSArray<NSString *> *) and unspecialized types (NSArray *) are
represented, separately.

appropriate. Perform semantic analysis of type bounds for type
parameters, both in isolation and across classes/categories/extensions
to ensure consistency.

Also handle (de-)serialization of Objective-C type parameter lists,
along with sundry other things one must do to add a new declaration to
Clang.

Note that Objective-C type parameters are typedef name declarations,
like typedefs and C++11 type aliases, in support of type erasure.

We use findModuleForHeader() in several places, but in header search we

Now we will find the module unconditionally for frameworks.  For regular
frameworks, we use the spelling of the module name from the module map
file, and for inferred ones we use the canonical directory name.

In the future we might want to lock down framework modules sufficiently
that these name mismatches cannot happen.

Ted Kremenek 7a1ef0ddca Change OptionalFlag::setPosition() to set the flag as well.
This change reduces some unnecessary boilerplate
since all calls to 'setPosition' are currently paired
with setting the flag of OptionalFlag.

No functionality change.

Yaron Keren 1c0070c65d Support mingw-w64 and mingw.org toolchains at any install location.
No more hardcoded paths: clang will use -sysroot as gcc root location if
provided. Otherwise, it will search for gcc on the path. If not found it
will use the driver installed location.

Peter Collingbourne 581f438f4c Driver: add support for linking the UBSan runtime library on Windows.
On Windows the user may invoke the linker directly, so we might not have an
opportunity to add runtime library flags to the linker command line. Instead,
instruct the code generator to embed linker directive in the object file
that cause the required runtime libraries to be linked.

We might also want to do something similar for ASan, but it seems to have
its own special complexities which may make this infeasible.

Reid Kleckner d0d9a1f63f [SEH] Add 32-bit lowering for SEH __try
This re-lands r236052 and adds support for __exception_code().

In 32-bit SEH, the exception code is not available in eax. It is only
available in the filter function, and now we arrange to load it and
store it into an escaped variable in the parent frame.

As a consequence, we have to disable the "catch i8* null" optimization
on 32-bit and always generate a filter function. We can re-enable the
optimization if we detect an __except block that doesn't use the
exception code, but this probably isn't worth optimizing.

Richard Smith 2aedca340c [modules] Before checking whether the controlling macro of a header is defined,
update the identifier in case we've imported a definition of the macro (and
thus the contents of the header) from a module.

Also fold ExternalIdentifierLookup into ExternalPreprocessorSource; it no longer
makes sense to keep these separate now that the only user of the former also
needs the latter.

Richard Smith 035f6dc9d1 [modules] Make the include guard optimization fire a bit more when considering
re-entering a modular header.

When we do the include guard check, we're in the visibility state for the file
with the #include; the include guard may not be visible there, but we don't
actually need it to be: if we've already parsed the submodule we're considering
entering, it's always safe to skip it.
