llvm: update llvm and friends to 13.0.0

Tested on NetBSD-current and 9.1/amd64.

Also update packages tightly coupled to llvm, if new versions are
available.

Mark creduce, include-what-you-use, and zig broken (waiting for a
new release).

Changes:

Non-comprehensive list of changes in this release

    Windows Control-flow Enforcement Technology: the -ehcontguard
    option now emits valid unwind entrypoints which are validated
    when the context is being set during exception handling.

    Flang is now included in the binary packages released by LLVM.

    The debuginfo-test project has been renamed cross-project-tests
    and is now intended for testing components from multiple
    projects, not just debug information. The new „ŗ◊ńross-project-tests„ŗ    name replaces „ŗ◊Ňebuginfo-test„ŗin LLVM_ENABLE_PROJECTS, and a
    new check-cross-project-tests target has been added for running
    all tests in the project. The pre-existing check-debuginfo-
    test target remains for running just the debug information
    tests. (D95339 and D96513)

Changes to the LLVM IR

    The inalloca attribute now has a mandatory type field, similar
    to byval and sret.

    The opaque pointer type ptr has been introduced. It is still
    in the process of being worked on and should not be used yet.

    Using the legacy pass manager for the optimization pipeline is
    deprecated and will be removed after LLVM 14. In the meantime,
    only minimal effort will be made to maintain the legacy pass
    manager for the optimization pipeline.

Changes to building LLVM

    The build system now supports building multiple distributions,
    so that you can e.g. have one distribution containing just
    tools and another for libraries (to enable development). See
    Multi-distribution configurations for details.

Changes to the AArch64 Backend

    Introduced assembly support for Armv9-A„ŗ—‘ Realm Management
    Extension (RME) and Scalable Matrix Extension (SME).

    Produce proper cross-section relative relocations on COFF

    Fixed the calling convention on Windows for variadic functions
    involving floats in the fixed arguments

Changes to the ARM Backend

    Produce proper cross-section relative relocations on COFF

Changes to the Hexagon Target

    The Hexagon target now supports V68/HVX ISA.

Changes to the C API

    The C API functions LLVMGetAlignment and LLVMSetAlignment now
    allow changing alignment on atomicrmw and cmpxchg instructions

    A new entry LLVMDIArgListMetadataKind was added to the
    LLVMMetadataKind enum, representing DIArgLists (D88175)

    Type attributes have been added to LLVM-C, introducing
    LLVMCreateTypeAttribute, LLVMGetTypeAttributeValue and
    LLVMIsTypeAttribute. (D977763„ŗ

    The LTO_API_VERSION was bumped to 28, introducing a new function
    lto_set_debug_options for parsing LTO debug options (D92611)

    LLVMJITTargetSymbolFlags was renamed to LLVMJITSymbolTargetFlags
    (rG8d718a0bff73af066675a6258c01307937c33cf9)

    The C API received support for creating custom ORCv2
    MaterializationUnits and APIs to retrieve an LLJIT instance„ŗ—‘
    linking layers. An ABI breaking change for LLVMOrcAbsoluteSymbols
    was introduced to make it consistent with
    LLVMOrcCreateCustomMaterializationUnit.
    (rGc8fc5e3ba942057d6c4cdcd1faeae69a28e7b671)

    The C API received support for adding ORCv2 object buffers
    directly to an object layer.
    (rG7b73cd684a8d5fb44d34064200f10e2723085c33)

    A breaking change to LLVMGetInlineAsm was introduced, adding
    a ninth argument LLVMBool CanThrow (D95745)

    The C API received support for calling into the new pass manager.
    (D102136)

    The C API function LLVMIntrinsicCopyOverloadedName has been
    deprecated. Please migrate to LLVMIntrinsicCopyOverloadedName2
    which takes an extra module argument and which also handles
    unnamed types. (D99173)

    The C API received support for dumping objects from ORCv2
    (rGcec8e69f01c3374cb38c6683058381b96fab8f89)

    A breaking change to LLVMOrcObjectTransformLayerTransformFunction
    was introduced, changing the order of the function pointer„ŗ—‘
    arguments. (rG8962c68ad007a525f9daa987c99eda57e0d0069a)

    The C API received support for accessing utilities from the
    LLJIT IRTransformLayer and ThreadSafeModule classes. (D103855)

    The C API received support for creating lazy-export
    MaterializationUnits (D104672)

    The C API function LLVMPassBuilderOptionsSetCoroutines was
    removed because couroutine passes have been enabled by default.
    (D105877)

    comdat noduplicates was renamed to comdat nodeduplicate and as
    a result, LLVMNoDuplicatesComdatSelectionKind was renamed to
    LLVMNoDeduplicateComdatSelectionKind. (D106319)

Changes to the FastISel infrastructure

    FastISel no longer tracks killed registers, and instead leaves
    this to the register allocator. This means that hasTrivialKill()
    is removed, as well as the OpNIsKill parameters to the fastEmit_*()
    family of functions.

Changes to the LLVM tools

    The options --build-id-link-{dir,input,output} have been deleted.
    (D96310)

    Support for in-order processors has been added to llvm-mca.
    (D94928)

    llvm-objdump supports -M {att,intel} now. --x86-asm-syntax is
    a deprecated internal option which will be removed in LLVM
    14.0.0. (D101695)

    The llvm-readobj short aliases -s (previously --sections) and
    -t (previously --syms) have been changed to --syms and
    --section-details respectively, to match llvm-readelf. (D105055)

    The llvm-nm short aliases -M (--print-armap), -U (--defined-only),
    and -W (--no-weak) are now deprecated. Use the long form versions
    instead. The alias --just-symbol-name is now deprecated in
    favor of --format=just-symbols and -j. (D105330)

    In lli the default JIT engine switched from MCJIT (-jit-kind=mcjit)
    to ORC (-jit-kind=orc). (D98931)

    llvm-rc got support for invoking Clang to preprocess its input.
    (D100755)

    llvm-rc got a GNU windres compatible frontend, llvm-windres.
    (D100756)

    llvm-ml has improved compatibility with MS ml.exe, managing to
    assemble more asm files.

Changes to LLDB

    LLDB executable is now included in pre-built LLVM binaries.

    LLDB now includes full featured support for AArch64 SVE register
    access.

    LLDB now supports AArch64 Pointer Authentication, allowing
    stack unwind with signed return address.

    LLDB now supports debugging programs on AArch64 Linux that use
    memory tagging (MTE).

    Added memory tag read and memory tag write commands.

    The memory region command will note when a region has memory
    tagging enabled.

    Synchronous and asynchronous tag faults are recognised.

    Synchronous tag faults have memory tag annotations in addition
    to the usual fault address.

clang: updated to 12.0.1

12.0.1:

Non-comprehensive list of changes in this release

The builtin intrinsics __builtin_bitreverse8, __builtin_bitreverse16, __builtin_bitreverse32 and __builtin_bitreverse64 may now be used within constant expressions.
The builtin intrinsics __builtin_rotateleft8, __builtin_rotateleft16, __builtin_rotateleft32 and __builtin_rotateleft64 may now be used within constant expressions.
The builtin intrinsics __builtin_rotateright8, __builtin_rotateright16, __builtin_rotateright32 and __builtin_rotateright64 may now be used within constant expressions.
New Compiler Flags

„ŗAArch64 options -moutline-atomics, -mno-outline-atomics to enable and disable calls to helper functions implementing atomic operations. These out-of-line helpers like Ōņ_aarch64_cas8_relax„ŗwill detect at runtime AArch64 Large System Extensions (LSE) availability and either use their atomic instructions, or falls back to LL/SC loop. These options do not apply if the compilation target supports LSE. Atomic instructions are used directly in that case. The option„ŗ—‘ behaviour mirrors GCC, the helpers are implemented both in compiler-rt and libgcc.
New option -fbinutils-version= specifies the targeted binutils version. For example, -fbinutils-version=2.35 means compatibility with GNU as/ld before 2.35 is not needed: new features can be used and there is no need to work around old GNU as/ld bugs.
Deprecated Compiler Flags

The following options are deprecated and ignored. They will be removed in future versions of Clang.

The clang-cl /fallback flag, which made clang-cl invoke Microsoft Visual C++ on files it couldn„ŗ—’ compile itself, has been deprecated. It will be removed in Clang 13.
„ŗModified Compiler Flags

On ELF, -gz now defaults to -gz=zlib with the integrated assembler. It produces SHF_COMPRESSED style compression of debug information. GNU binutils 2.26 or newer, or lld is required to link produced object files. Use -gz=zlib-gnu to get the old behavior.

Now that this pointers are tagged with nonnull and dereferenceable(N), -fno-delete-null-pointer-checks has gained the power to remove the nonnull attribute on this for configurations that need it to be nullable.

-gsplit-dwarf no longer implies -g2.

-fasynchronous-unwind-tables is now the default on Linux AArch64/PowerPC. This behavior matches newer GCC. (D91760) (D92054)

Support has been added for the following processors (command-line identifiers in parentheses):

Arm Cortex-A78C (cortex-a78c).
Arm Cortex-R82 (cortex-r82).
Arm Neoverse V1 (neoverse-v1).
Arm Neoverse N2 (neoverse-n2).
Fujitsu A64FX (a64fx).
For example, to select architecture support and tuning for Neoverse-V1 based systems, use -mcpu=neoverse-v1.
Removed Compiler Flags

The following options no longer exist.

clang-cl—‘ /Zd flag no longer exist. But -gline-tables-only still exists and does the same thing.
New Pragmas in Clang

„ŗModified Pragmas in Clang

The pragma clang loop vectorize_width„ŗhas been extended to support an optional „ŗŌ«ixed|scalable„ŗargument, which can be used to indicate that the compiler should use fixed-width or scalable vectorization. Fixed-width is assumed by default.

Scalable or vector length agnostic vectorization is an experimental feature for targets that support scalable vectors. For more information please refer to the Clang Language Extensions documentation.
Attribute Changes in Clang

Added support for the C++20 likelihood attributes [[likely]] and [[unlikely]]. As an extension they can be used in C++11 and newer. This extension is enabled by default.

clang: updated to 8.0.0

Clang 8.0.0:

Major New Features

* Clang supports use of a profile remapping file, which permits profile data captured for one version of a program to be applied when building another version where symbols have changed (for example, due to renaming a class or namespace). See the UsersManual for details.

* Clang has new options to initialize automatic variables with a pattern. The default is still that automatic variables are uninitialized. This isn„ŗ—’ meant to change the semantics of C and C++. Rather, it„ŗ—‘ meant to be a last resort when programmers inadvertently have some undefined behavior in their code. These options aim to make undefined behavior hurt less, which security-minded people will be very happy about.

* Improvements to Clang„ŗ—‘ diagnostics

Non-comprehensive list of changes in this release
* The experimental feature Pretokenized Headers (PTH) was removed in its entirely from Clang. The feature did not properly work with about 1/3 of the possible tokens available and was unmaintained.
* The internals of libc++ include directory detection on MacOS have changed. Instead of running a search based on the -resource-dir flag, the search is now based on the path of the compiler in the filesystem. The default behaviour should not change. However, if you override -resource-dir manually and rely on the old behaviour you will need to add appropriate compiler flags for finding the corresponding libc++ include directory.
* The integrated assembler is used now by default for all MIPS targets.
* Improved support for MIPS N32 ABI and MIPS R6 target triples.
* Clang now includes builtin functions for bitwise rotation of common value sizes, such as: __builtin_rotateleft32
* Improved optimization for the corresponding MSVC compatibility builtins such as _rotl().

llvm: updated to 7.0.0

LLVM 7.0.0 Release

The release contains the work on trunk up to SVN revision 338536 plus
work on the release branch. It is the result of the community's work
over the past six months, including: function multiversioning in Clang
with the 'target' attribute for ELF-based x86/x86_64 targets, improved
PCH support in clang-cl, preliminary DWARF v5 support, basic support
for OpenMP 4.5 offloading to NVPTX, OpenCL C++ support, MSan, X-Ray
and libFuzzer support for FreeBSD, early UBSan, X-Ray and libFuzzer
support for OpenBSD, UBSan checks for implicit conversions, many
long-tail compatibility issues fixed in lld which is now production
ready for ELF, COFF and MinGW, new tools llvm-exegesis, llvm-mca and
diagtool. And as usual, many optimizations, improved diagnostics, and
bug fixes.

clang: enable __float128 on netbsd/x86

While it is debatable whether we want to have this definition upstream,
this is very necessary in the package for the purpose of building
www/firefox once it is updated to 63.0.

This is because netbsd's base libstdc++ has some __float128 in headers
and otherwise we get fatal errors in clang builds, or in firefox's case,
when generating bindings for Rust via clang.

LLVM 4.0.0:
The minimum compiler version required for building LLVM has been raised to 4.8 for GCC and 2015 for Visual Studio.
The C API functions LLVMAddFunctionAttr, LLVMGetFunctionAttr, LLVMRemoveFunctionAttr, LLVMAddAttribute, LLVMRemoveAttribute, LLVMGetAttribute, LLVMAddInstrAttribute and LLVMRemoveInstrAttribute have been removed.
The C API enum LLVMAttribute has been deleted.
The definition and uses of LLVM_ATRIBUTE_UNUSED_RESULT in the LLVM source were replaced with LLVM_NODISCARD, which matches the C++17 [[nodiscard]] semantics rather than gcc„ŗ—‘ __attribute__((warn_unused_result)).
The Timer related APIs now expect a Name and Description. When upgrading code the previously used names should become descriptions and a short name in the style of a programming language identifier should be added.
LLVM now handles invariant.group across different basic blocks, which makes it possible to devirtualize virtual calls inside loops.
The aggressive dead code elimination phase („ŗ◊¬dce„ŗ now removes branches which do not effect program behavior. Loops are retained by default since they may be infinite but these can also be removed with LLVM option -adce-remove-loops when the loop body otherwise has no live operations.
The llvm-cov tool can now export coverage data as json. Its html output mode has also improved.

Update to clang-3.8.0. Split out llvm tools to lang/llvm.
Packaged in pkgsrc-wip by myself and Kamil.
Remove stale pkgsrc/SunOS bread crumbs that were difficult to merge
following the build framework switch. Needs to be redone. (Sorry!)

Summary of significant changes in LLVM:
- switch build framework from autoconf to CMake
- llvm-ar now supports thin archives.
- llvm doesn t produce .data.rel.ro.local or .data.rel sections anymore.
- opional support for linking clang and the LLVM tools with a single
  libLLVM shared library

  pkgsrc note: we have this library in lang/libLLVM, but we don't currently
  use it. We may do so in the future if/when the API matures.

- The optimization to move the prologue and epilogue of functions in colder
  code path (shrink-wrapping) is now enabled by default
- new target-independent gcc-compatible emulated Thread Local Storage mode
- various target specific optimizations

Summary of significant changes in Clang:

- new compiler flags for tuning what DWARF information is included
- better strict alignment handling
- better support for __builtin_object_size

Unbreak C++ on NetBSD, by popular demand.

Background:
LLVM 3.6 upstream added support for being a native toolchain on NetBSD.
This changed the default C++ runtime library from libstdc++ to libc++.
Patch this in pkgsrc's clang so we continue to use libstdc++ (for now)
Proper support for libc++ should be added later (perhaps w/ PKG_OPTIONs).
Thanks to Joerg for explaining the problem.

Changes 3.5.1:

Clang can now successfully self-host itself on Linux/Sparc64 and on FreeBSD/Sparc64.
LLVM now assumes the assembler supports .loc for generating debug line numbers. The old support for printing the debug line info directly was only used by llc and has been removed.
All inline assembly is parsed by the integrated assembler when it is enabled. Previously this was only the case for object-file output. It is now the case for assembly output as well. The integrated assembler can be disabled with the -no-integrated-as option.
llvm-ar now handles IR files like regular object files. In particular, a regular symbol table is created for symbols defined in IR files, including those in file scope inline assembly.
LLVM now always uses cfi directives for producing most stack unwinding information.
The prefix for loop vectorizer hint metadata has been changed from llvm.vectorizer to llvm.loop.vectorize. In addition, llvm.vectorizer.unroll metadata has been renamed llvm.loop.interleave.count.
Some backends previously implemented Atomic NAND(x,y) as x & ~y. Now all backends implement it as ~(x & y), matching the semantics of GCC 4.4 and later.

Update to 3.4

* Tested under NetBSD/amd64 6.99.28 and Debian GNU/Linux/amd64 7.3

Changelog:
From: http://llvm.org/svn/llvm-project/llvm/tags/RELEASE_34/final/docs/ReleaseNotes.rst
Non-comprehensive list of changes in this release
=================================================

* This is expected to be the last release of LLVM which compiles using a C++98
  toolchain. We expect to start using some C++11 features in LLVM and other
  sub-projects starting after this release. That said, we are committed to
  supporting a reasonable set of modern C++ toolchains as the host compiler on
  all of the platforms. This will at least include Visual Studio 2012 on
  Windows, and Clang 3.1 or GCC 4.7.x on Mac and Linux. The final set of
  compilers (and the C++11 features they support) is not set in stone, but we
  wanted users of LLVM to have a heads up that the next release will involve
  a substantial change in the host toolchain requirements.

* The regression tests now fail if any command in a pipe fails. To disable it in
  a directory, just add ``config.pipefail = False`` to its ``lit.local.cfg``.
  See :doc:`Lit <CommandGuide/lit>` for the details.

* Support for exception handling has been removed from the old JIT. Use MCJIT
  if you need EH support.

* The R600 backend is not marked experimental anymore and is built by default.

* ``APFloat::isNormal()`` was renamed to ``APFloat::isFiniteNonZero()`` and
  ``APFloat::isIEEENormal()`` was renamed to ``APFloat::isNormal()``. This
  ensures that ``APFloat::isNormal()`` conforms to IEEE-754R-2008.

* The library call simplification pass has been removed.  Its functionality
  has been integrated into the instruction combiner and function attribute
  marking passes.

* Support for building using Visual Studio 2008 has been dropped. Use VS 2010
  or later instead. For more information, see the `Getting Started using Visual
  Studio <GettingStartedVS.html>`_ page.

* The Loop Vectorizer that was previously enabled for ``-O3`` is now enabled
  for ``-Os`` and ``-O2``.

* The new SLP Vectorizer is now enabled by default.

* ``llvm-ar`` now uses the new Object library and produces archives and
  symbol tables in the gnu format.

* FileCheck now allows specifing ``-check-prefix`` multiple times. This
  helps reduce duplicate check lines when using multiple RUN lines.

* The bitcast instruction no longer allows casting between pointers
   with different address spaces. To achieve this, use the new addrspacecast
   instruction.

* Different sized pointers for different address spaces should now
  generally work. This is primarily useful for GPU targets.

* OCaml bindings have been significantly extended to cover almost all of the
  LLVM libraries.

Mips Target
-----------

Support for the MIPS SIMD Architecture (MSA) has been added. MSA is supported
through inline assembly, intrinsics with the prefix '``__builtin_msa``', and
normal code generation.

For more information on MSA (including documentation for the instruction set),
see the `MIPS SIMD page at Imagination Technologies
<http://imgtec.com/mips/mips-simd.asp>`_

PowerPC Target
--------------

Changes in the PowerPC backend include:

* fast-isel support (for faster ``-O0`` code generation)
* many improvements to the builtin assembler
* support for generating unaligned (Altivec) vector loads
* support for generating the fcpsgn instruction
* generate ``frin`` for ``round()`` (not ``nearbyint()`` and ``rint()``, which
  had been done only in fast-math mode)
* improved instruction scheduling for embedded cores (such as the A2)
* improved prologue/epilogue generation (especially in 32-bit mode)
* support for dynamic stack alignment (and dynamic stack allocations with large alignments)
* improved generation of counter-register-based loops
* bug fixes

SPARC Target
------------

The SPARC backend got many improvements, namely

* experimental SPARC V9 backend
* JIT support for SPARC
* fp128 support
* exception handling
* TLS support
* leaf functions optimization
* bug fixes

SystemZ/s390x Backend
---------------------

LLVM and clang can now optimize for zEnterprise z196 and zEnterprise EC12
targets.  In clang these targets are selected using ``-march=z196`` and
``-march=zEC12`` respectively.

From: http://llvm.org/svn/llvm-project/cfe/tags/RELEASE_34/final/docs/ReleaseNotes.rst
What's New in Clang 3.4?
========================

Some of the major new features and improvements to Clang are listed here.
Generic improvements to Clang as a whole or to its underlying infrastructure
are described first, followed by language-specific sections with improvements
to Clang's support for those languages.

Last release which will build as C++98
--------------------------------------

This is expected to be the last release of Clang which compiles using a C++98
toolchain. We expect to start using some C++11 features in Clang starting after
this release. That said, we are committed to supporting a reasonable set of
modern C++ toolchains as the host compiler on all of the platforms. This will
at least include Visual Studio 2012 on Windows, and Clang 3.1 or GCC 4.7.x on
Mac and Linux. The final set of compilers (and the C++11 features they support)
is not set in stone, but we wanted users of Clang to have a heads up that the
next release will involve a substantial change in the host toolchain
requirements.

Note that this change is part of a change for the entire LLVM project, not just
Clang.

Major New Features
------------------

Improvements to Clang's diagnostics
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Clang's diagnostics are constantly being improved to catch more issues, explain
them more clearly, and provide more accurate source information about them. The
improvements since the 3.3 release include:

- -Wheader-guard warns on mismatches between the #ifndef and #define lines
  in a header guard.

  .. code-block:: c

    #ifndef multiple
    #define multi
    #endif

  returns
  `warning: 'multiple' is used as a header guard here, followed by #define of a different macro [-Wheader-guard]`

- -Wlogical-not-parentheses warns when a logical not ('!') only applies to the
  left-hand side of a comparison.  This warning is part of -Wparentheses.

  .. code-block:: c++

    int i1 = 0, i2 = 1;
    bool ret;
    ret = !i1 == i2;

  returns
  `warning: logical not is only applied to the left hand side of this comparison [-Wlogical-not-parentheses]`


- Boolean increment, a deprecated feature, has own warning flag
  -Wdeprecated-increment-bool, and is still part of -Wdeprecated.
- Clang errors on builtin enum increments and decrements.

  .. code-block:: c++

    enum A { A1, A2 };
    void test() {
    	A a;
    	a++;
    }

  returns
  `error: must use 'enum' tag to refer to type 'A'`


- -Wloop-analysis now warns on for-loops which have the same increment or
  decrement in the loop header as the last statement in the loop.

  .. code-block:: c

    void foo(char *a, char *b, unsigned c) {
	  for (unsigned i = 0; i < c; ++i) {
		a[i] = b[i];
		++i;
	  }
    }

  returns
  `warning: variable 'i' is incremented both in the loop header and in the loop body [-Wloop-analysis]`

- -Wuninitialized now performs checking across field initializers to detect
  when one field in used uninitialized in another field initialization.

  .. code-block:: c++

    class A {
      int x;
      int y;
      A() : x(y) {}
    };

  returns
  `warning: field 'y' is uninitialized when used here [-Wuninitialized]`

- Clang can detect initializer list use inside a macro and suggest parentheses
  if possible to fix.
- Many improvements to Clang's typo correction facilities, such as:

  + Adding global namespace qualifiers so that corrections can refer to shadowed
    or otherwise ambiguous or unreachable namespaces.
  + Including accessible class members in the set of typo correction candidates,
    so that corrections requiring a class name in the name specifier are now
    possible.
  + Allowing typo corrections that involve removing a name specifier.
  + In some situations, correcting function names when a function was given the
    wrong number of arguments, including situations where the original function
    name was correct but was shadowed by a lexically closer function with the
    same name yet took a different number of arguments.
  + Offering typo suggestions for 'using' declarations.
  + Providing better diagnostics and fixit suggestions in more situations when
    a '->' was used instead of '.' or vice versa.
  + Providing more relevant suggestions for typos followed by '.' or '='.
  + Various performance improvements when searching for typo correction
    candidates.

- `LeakSanitizer <LeakSanitizer.html>`_ is an experimental memory leak detector
  which can be combined with AddressSanitizer.

New Compiler Flags
------------------

- Clang no longer special cases -O4 to enable lto. Explicitly pass -flto to
  enable it.
- Clang no longer fails on >= -O5. These flags are mapped to -O3 instead.
- Command line "clang -O3 -flto a.c -c" and "clang -emit-llvm a.c -c"
  are no longer equivalent.
- Clang now errors on unknown -m flags (``-munknown-to-clang``),
  unknown -f flags (``-funknown-to-clang``) and unknown
  options (``-what-is-this``).

C Language Changes in Clang
---------------------------

- Added new checked arithmetic builtins for security critical applications.

C++ Language Changes in Clang
-----------------------------

- Fixed an ABI regression, introduced in Clang 3.2, which affected
  member offsets for classes inheriting from certain classes with tail padding.
  See Bug16537.

- Clang 3.4 supports the 2013-08-28 draft of the ISO WG21 SG10 feature test
  macro recommendations. These aim to provide a portable method to determine
  whether a compiler supports a language feature, much like Clang's
  |has_feature macro|_.

.. |has_feature macro| replace:: ``__has_feature`` macro
.. _has_feature macro: LanguageExtensions.html#has-feature-and-has-extension

C++1y Feature Support
^^^^^^^^^^^^^^^^^^^^^

Clang 3.4 supports all the features in the current working draft of the
upcoming C++ standard, provisionally named C++1y. Support for the following
major new features has been added since Clang 3.3:

- Generic lambdas and initialized lambda captures.
- Deduced function return types (``auto f() { return 0; }``).
- Generalized ``constexpr`` support (variable mutation and loops).
- Variable templates and static data member templates.
- Use of ``'`` as a digit separator in numeric literals.
- Support for sized ``::operator delete`` functions.

In addition, ``[[deprecated]]`` is now accepted as a synonym for Clang's
existing ``deprecated`` attribute.

Use ``-std=c++1y`` to enable C++1y mode.

OpenCL C Language Changes in Clang
----------------------------------

- OpenCL C "long" now always has a size of 64 bit, and all OpenCL C
  types are aligned as specified in the OpenCL C standard. Also,
  "char" is now always signed.

Internal API Changes
--------------------

These are major API changes that have happened since the 3.3 release of
Clang. If upgrading an external codebase that uses Clang as a library,
this section should help get you past the largest hurdles of upgrading.

Wide Character Types
^^^^^^^^^^^^^^^^^^^^

The ASTContext class now keeps track of two different types for wide character
types: WCharTy and WideCharTy. WCharTy represents the built-in wchar_t type
available in C++. WideCharTy is the type used for wide character literals; in
C++ it is the same as WCharTy, but in C99, where wchar_t is a typedef, it is an
integer type.

Static Analyzer
---------------

The static analyzer has been greatly improved. This impacts the overall analyzer quality and reduces a number of false positives.
In particular, this release provides enhanced C++ support, reasoning about initializer lists, zeroing constructors, noreturn destructors and modeling of destructor calls on calls to delete.

Clang Format
------------

Clang now includes a new tool ``clang-format`` which can be used to
automatically format C, C++ and Objective-C source code. ``clang-format``
automatically chooses linebreaks and indentation and can be easily integrated
into editors, IDEs and version control systems. It supports several pre-defined
styles as well as precise style control using a multitude of formatting
options. ``clang-format`` itself is just a thin wrapper around a library which
can also be used directly from code refactoring and code translation tools.
More information can be found on `Clang Format's
site <http://clang.llvm.org/docs/ClangFormat.html>`_.

Changes 3.3:
The CellSPU port has been removed. It can still be found in older versions.
The IR-level extended linker APIs (for example, to link bitcode files out of archives) have been removed. Any existing clients of these features should move to using a linker with integrated LTO support.
LLVM and Clang„ŗ—‘ documentation has been migrated to the Sphinx documentation generation system which uses easy-to-write reStructuredText. See llvm/docs/README.txt for more information.
TargetTransformInfo (TTI) is a new interface that can be used by IR-level passes to obtain target-specific information, such as the costs of instructions. Only „ŗ◊≠owering„ŗpasses such as LSR and the vectorizer are allowed to use the TTI infrastructure.
We„ŗ—◊e improved the X86 and ARM cost model.
The Attributes classes have been completely rewritten and expanded. They now support not only enumerated attributes and alignments, but „ŗ◊‘tring„ŗattributes, which are useful for passing information to code generation. See How To Use Attributes for more details.
TableGen„ŗ—‘ syntax for instruction selection patterns has been simplified. Instead of specifying types indirectly with register classes, you should now specify types directly in the input patterns. See SparcInstrInfo.td for examples of the new syntax. The old syntax using register classes still works, but it will be removed in a future LLVM release.
MCJIT now supports exception handling. Support for it in the old jit will be removed in the 3.4 release.
Command line options can now be grouped into categories which are shown in the output of -help. See Grouping options into categories.
The appearance of command line options in -help that are inherited by linking with libraries that use the LLVM Command line support library can now be modified at runtime. See The cl::getRegisteredOptions function.

lang/clang: Fix binary generation on latest DragonFly

Clang was hardwired to search for crt* stuff and libstdc++ at
/usr/lib/gcc41.  This worked for most people even when DragonFly
moved to gcc 4.4 as the primary base compiler since gcc 4.1 was
usually also on the system.

With the release of DragonFly 3.2, gcc 4.7 replaced gcc 4.1 and
clang stopped compiling due to not being able to find libraries and
crt* objects.  The new patches make clang driver first look for
gcc 4.7 and failing to find that: gcc 4.4.

The other patches were "de-fuzzed".
Revision bump was necessary because clang did build, it just didn't
work.

lang/clang: USE_TOOLS+= pod2man pod2html, fix DragonFly

For some reason, LLVM is using autoconf files from 2003 which is before
DragonFly even existed.  I submitted a bug report #12944 at llvm.org's
bugzilla to request they use versions from 2012.

Also, installation fails at document generation without some extra tools.
No need to revbump, either built or it didn't without these packages.

Changes 3.1:
* Major New Features
  - AddressSanitizer, a fast memory error detector.
  - MachineInstr Bundles, Support to model instruction bundling / packing.
  - ARM Integrated Assembler, A full featured assembler and direct-to-object
    support for ARM.
  - Basic Block Placement Probability driven basic block placement.
* LLVM IR and Core Improvements
  - A new type representing 16 bit half floating point values has been added.
  - IR now supports vectors of pointers, including vector GEPs.
  - Module flags have been introduced. They convey information about the module
    as a whole to LLVM subsystems. This is currently used to encode Objective C
    ABI information.
  - Loads can now have range metadata attached to them to describe the possible
    values being loaded.
  - The llvm.ctlz and llvm.cttz intrinsics now have an additional argument which
    indicates whether the behavior of the intrinsic is undefined on a zero
    input. This can be used to generate more efficient code on platforms that
    only have instructions which don't return the type size when counting bits
    in 0.
* Optimizer Improvements
  - The loop unroll pass now is able to unroll loops with run-time trip counts.
    This feature is turned off by default, and is enabled with the
    -unroll-runtime flag.
  - A new basic-block autovectorization pass is available. Pass -vectorize to
    run this pass along with some associated post-vectorization cleanup passes.
    For more information, see the EuroLLVM 2012 slides: Autovectorization with
    LLVM.
  - Inline cost heuristics have been completely overhauled and now closely model
    constant propagation through call sites, disregard trivially dead code
    costs, and can model C++ STL iterator patterns.

LLVM 3.0 includes several major changes and big features:
* llvm-gcc is no longer supported, and not included in the release. We recommend
  switching to Clang or DragonEgg.
* The linear scan register allocator has been replaced with a new "greedy"
  register allocator, enabling live range splitting and many other optimizations  that lead to better code quality. Please see its blog post or its talk at the
  Developer Meeting for more information.
* LLVM IR now includes full support for atomics memory operations intended to
  support the C++'11 and C'1x memory models. This includes atomic load and
  store, compare and exchange, and read/modify/write instructions as well as
  a full set of memory ordering constraints. Please see the Atomics Guide for
  more information.
* The LLVM IR exception handling representation has been redesigned and
  reimplemented, making it more elegant, fixing a huge number of bugs, and
  enabling inlining and other optimizations. Please see its blog post and the
  Exception Handling documentation for more information.
* The LLVM IR Type system has been redesigned and reimplemented, making it
  faster and solving some long-standing problems. Please see its blog post for
  more information.
* The MIPS backend has made major leaps in this release, going from an
  experimental target to being virtually production quality and supporting
  a wide variety of MIPS subtargets. See the MIPS section below for more
  information.
* The optimizer and code generator now supports gprof and gcov-style coverage
  and profiling information, and includes a new llvm-cov tool (but also works
  with gcov). Clang exposes coverage and profiling through GCC-compatible
  command line options.

LLVM 2.9 includes several major new capabilities:
* Type Based Alias Analysis (TBAA) is now implemented and turned on by default
  in Clang. This allows substantially better load/store optimization in some
  cases. TBAA can be disabled by passing -fno-strict-aliasing.
* This release has seen a continued focus on quality of debug information. LLVM
  now generates much higher fidelity debug information, particularly when
  debugging optimized code.
* Inline assembly now supports multiple alternative constraints.
* A new backend for the NVIDIA PTX virtual ISA (used to target its GPUs) is
  under rapid development. It is not generally useful in 2.9, but is making
  rapid progress.

Changes 2.8:
* libc++ and LLDB are major new additions to the LLVM collective.
* LLVM 2.8 now has pretty decent support for debugging optimized code.
  You should be able to reliably get debug info for function arguments,
  assuming that the value is actually available where you have stopped.
* A new 'llvm-diff' tool is available that does a semantic diff of .ll files.
* The MC subproject has made major progress in this release. Direct .o file
  writing support for darwin/x86[-64] is now reliable and support for other
  targets and object file formats are in progress.
* The memcpy, memmove, and memset intrinsics now take address space qualified
  pointers and a bit to indicate whether the transfer is "volatile" or not.
* Per-instruction debug info metadata is much faster and uses less memory by
  using the new DebugLoc class.
* LLVM IR now has a more formalized concept of "trap values", which allow the
 optimizer to optimize more aggressively in the presence of undefined behavior,
 while still producing predictable results.
* LLVM IR now supports two new linkage types (linker_private_weak and
 linker_private_weak_def_auto) which map onto some obscure MachO concepts.
* The optimizer now has support for updating debug information as it goes.
  A key aspect of this is the new llvm.dbg.value intrinsic. This intrinsic
  represents debug info for variables that are promoted to SSA values
  (typically by mem2reg or the -scalarrepl passes).
* The JumpThreading pass is now much more aggressive about implied value
  relations, allowing it to thread conditions like "a == 4" when a is known to
  be 13 in one of the predecessors of a block. It does this in conjunction with
  the new LazyValueInfo analysis pass.
* The new RegionInfo analysis pass identifies single-entry single-exit regions
  in the CFG. You can play with it with the "opt -regions analyze" or "opt
  -view-regions" commands.
* The loop optimizer has significantly improved strength reduction and analysis
  capabilities. Notably it is able to build on the trap value and signed
  integer overflow information to optimize <= and >= loops.
* The CallGraphSCCPassManager now has some basic support for iterating within
  an SCC when a optimizer devirtualizes a function call. This allows inlining
  through indirect call sites that are devirtualized by store-load forwarding
  and other optimizations.
* The new -loweratomic pass is available to lower atomic instructions into
  their non-atomic form. This can be useful to optimize generic code that
  expects to run in a single-threaded environment.
