Alp Toker 73287bfe40 MSVC 2013 type trait support
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,
particularly anything that includes <type_traits>.

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 64197b9eb9 docs: clarify the role of compiler-builtin type trait primitives
Update the documentation to clarify the intent of clang's built-in type trait
facilities, their relation to user-facing C++ type traits and means to check
for availability.

Also explain that __has_feature() is not currently up to date and should not
generally be used in user code (there's a proposal to provide more consistent
checks via __has_builtin(), see cfe-dev).

Adrian Prantl a763447124 Implement a new -fstandalone-debug option. rdar://problem/15685848
It controls everything that -flimit-debug-info used to, plus the
vtable type optimization. The old -fno-limit-debug-info option is now an
alias to -fstandalone-debug and vice versa.

Standalone is the default on Darwin until dtrace is updated to work with
non-standalone debug info (rdar://problem/15758808).

Note: I kept the LimitedDebugInfo name in CodeGenOptions::DebugInfoKind
because NoStandaloneDebugInfo sounded even more confusing.

Add support for more filename extensions based on the list in the clang

Alexander Kornienko fdca83d487 Support GNU style rule to put a space before opening parenthesis.
Summary:
The rule from the GNU style states:
"We find it easier to read a program when it has spaces before the open-parentheses and after the commas."

http://www.gnu.org/prep/standards/standards.html#index-spaces-before-open_002dparen

This patch makes clang-format adds an option to put spaces before almost all open parentheses, except the cases, where different behavior is dictated by the style rules or language syntax:
  * preprocessor:
    ** function-like macro definitions can't have a space between the macro name and the parenthesis;
    ** `#if defined(...)` can have a space, but it seems, that it's more frequently used without a space in GCC, for example;
  * never add spaces after unary operators;
  * adding spaces between two opening parentheses is controlled with the `SpacesInParentheses` option;
  * never add spaces between `[` and `(` (there's no option yet).

Alp Toker 7874bdc6c1 Revert "Using an invalid -O falls back on -O3 instead of an error"
Trying to fix test failures since earlier today.

One of the tests added in this commit is outputting test/Driver/clang_f_opts.s
which the builders that build in-tree (eg. clang-native-arm-cortex-a9) are
trying to run as a test case, causing failures.

clang_f_opts.c:
  If -### doesn't emit the warning then this test probably shouldn't be in
  here in the first place. Frontend maybe?

invalid-o-level.c:
  Running %clang_cc1 in the Driver tests doesn't make sense because -cc1
  bypasses the driver. (I'm not reverting the commit that introduced this but
  please fix instead of keeping it this way.)

Reverting to fix the build failures and also so that the tests can be thought
out more thoroughly.

This reverts commit r194817.

Daniel Jasper ca9f73812c Add -fmodule-map-file option.
With this option, arbitrarily named module map files can be specified
to be loaded as required for headers in the respective (sub)directories.

This, together with the extern module declaration allows for specifying
module maps in a modular fashion without the need for files called
"module.map".

Among other things, this allows a directory to contain two modules that
are completely independent of one another.

Daniel Jasper ba7f2f7110 Module use declarations (II)
Review: http://llvm-reviews.chandlerc.com/D1546.

I have picked up this patch form Lawrence
(http://llvm-reviews.chandlerc.com/D1063) and did a few changes.

From the original change description (updated as appropriate):
This patch adds a check that ensures that modules only use modules they
have so declared. To this end, it adds a statement on intended module
use to the module.map grammar:

  use module-id

A module can then only use headers from other modules if it 'uses' them.
This enforcement is off by default, but may be turned on with the new
option -fmodules-decluse.

When enforcing the module semantics, we also need to consider a source
file part of a module. This is achieved with a compiler option

-fmodule-name=<module-id>.

The compiler at present only applies restrictions to the module directly
being built.

Hal Finkel c4d7c82c7f Add the intrinsic __builtin_convertvector
LLVM supports applying conversion instructions to vectors of the same number of
elements (fptrunc, fptosi, etc.) but there had been no way for a Clang user to
cause such instructions to be generated when using builtin vector types.

C-style casting on vectors is already defined in terms of bitcasts, and so
cannot be used for these conversions as well (without leading to a very
confusing set of semantics). As a result, this adds a __builtin_convertvector
intrinsic (patterned after the OpenCL __builtin_astype intrinsic). This is
intended to aid the creation of vector intrinsic headers that create generic IR
instead of target-dependent intrinsics (in other words, this is a generic
_mm_cvtepi32_ps). As noted in the documentation, the action of
__builtin_convertvector is defined in terms of the action of a C-style cast on
each vector element.

Ed Schouten 401aebab93 Make __has_extension(c_thread_local) work.
Unlike C++11's "thread_local" keyword, C11's "_Thread_local" is in the
reserved namespace, meaning we provide it unconditionally; it is marked
as KEYALL in TokenKinds.def.

This means that like all the other C11 keywords, we can expose its
presence through __has_extension().

Daniel Jasper 97292843d0 Support for modular module-map-files
This patch is the first step to make module-map-files modular (instead
of requiring a single "module.map"-file per include directory). This
step adds a new "extern module" declaration that enables
module-map-files to reference one another along with a very basic
implementation.

The next steps are:

* Combine this with the use-declaration (from
  http://llvm-reviews.chandlerc.com/D1546) in order to only load module
  map files required for a specific compilation.
* Add an additional flag to start with a specific module-map-file (instead
  of requiring there to be at least one "module.map").

Nico Rieck 7857d46c64 Add -fansi-escape-codes option
Some build systems use pipes for stdin/stderr. On nix-ish platforms colored
output can be forced by -fcolor-diagnostics. On Windows this option has
no effect in these cases because LLVM uses the console API (which only
operates on the console buffer) even if a console wrapper capable of
interpreting ANSI escape codes is used.

The -fansi-escape-codes option allows switching from the console API to
ANSI escape codes. It has no effect on other platforms.

Hans Wennborg 9f6581bb88 Allow _clang-format as alternative to .clang-format config filename
Dotfiles are impractical on Windows. This makes clang-format search
for the style configuration file as '_clang-format' in addition to
the usual '.clang-format'. This is similar to how VIM searches for
'_vimrc' on Windows.

   autolinking. Instead, convert the existing flag into -fno-autolink (which
   should cover other autolinking code generation paths like #pragmas if and
   when we support them).

Jordan Rose 2de3daa0a2 [analyzer] Enable destructor inlining by default (c++-inlining=destructors).
This turns on not only destructor inlining, but inlining of constructors
for types with non-trivial destructors. Per r178516, we will still not
inline the constructor or destructor of anything that looks like a
container unless the analyzer-config option 'c++-container-inlining' is
set to 'true'.

In addition to the more precise path-sensitive model, this allows us to
catch simple smart pointer issues:

  #include <memory>

  void test() {
    std::auto_ptr<int> releaser(new int[4]);
  } // memory allocated with 'new[]' should not be deleted with 'delete'

Revert "Don't compute a patched/semantic storage class."

Rafael Espindola adea16bd9e Don't compute a patched/semantic storage class.
For variables and functions clang used to store two storage classes. The one
"as written" in the code and a patched one, which, for example, propagates
static to the following decls.

This apparently is from the days clang lacked linkage computation. It is now
redundant and this patch removes it.

Douglas Gregor bf7fc9c542 <rdar://problem/13509689> Introduce -module-file-info option that provides information about a particular module file.
This option can be useful for end users who want to know why they
ended up with a ton of different variants of the "std" module in their
module cache. This problem should go away over time, as we reduce the
need for module variants, but it will never go away entirely.
