Update more file headers across all of the LLVM projects in the monorepo to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648

_LIBCPP_BEGIN_NAMESPACE_STD
template <class _CharT, class _Traits>
[NFC] Rename _LIBCPP_TYPE_VIS_ONLY to _LIBCPP_TEMPLATE_VIS The name _LIBCPP_TYPE_VIS_ONLY is no longer accurate because both _LIBCPP_TYPE_VIS and _LIBCPP_TYPE_VIS_ONLY expand to __attribute__((__type_visibility__)) with Clang. The only remaining difference is that _LIBCPP_TYPE_VIS_ONLY can be applied to templates whereas _LIBCPP_TYPE_VIS cannot (due to dllimport/dllexport not being allowed on templates). This patch renames _LIBCPP_TYPE_VIS_ONLY to _LIBCPP_TEMPLATE_VIS. llvm-svn: 291035

[libcxx] Remove _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY That macro has been defined to _LIBCPP_HIDE_FROM_ABI_AFTER_V1 for many weeks now, so we're actually replacing uses of it for uses of _LIBCPP_HIDE_FROM_ABI_AFTER_V1 directly.

inline _LIBCPP_HIDE_FROM_ABI_AFTER_V1
[libc++] Add _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY to support GCC ABI compatibility Summary: GCC and Clang handle visibility attributes on the out-of-line definition of externally instantiated templates differently. For example in the reproducer below Clang will emit both 'foo' and 'bar' with default visibility while GCC only emits a non-hidden 'foo'. ``` // RUN: g++ -std=c++11 -shared -O3 test.cpp && sym_extract.py a.out // RUN: clang++ -std=c++11 -shared -O3 test.cpp && sym_extract.py a.out #define INLINE_VISIBILITY __attribute__((visibility("hidden"), always_inline)) template <class T> struct Foo { void foo(); void bar(); }; template <class T> void Foo<T>::foo() {} template <class T> inline INLINE_VISIBILITY void Foo<T>::bar() {} template struct Foo<int>; ``` This difference creates ABI incompatibilities between Clang and GCC built dylibs. Specifically GCC built dylibs lack definitions for various member functions of `basic_string`, `basic_istream`, `basic_ostream`, `basic_iostream`, and `basic_streambuf` (All of these types are externally instantiated). Surprisingly these missing symbols don't cause many problems because the functions are marked `always_inline` therefore the dylib definition is rarely needed. However when an out-of-line definition is required then GCC built dylibs will fail to link. For example [GCC built dylibs cannot build Clang](http://stackoverflow.com/questions/39454262/clang-build-errors). This patch works around this issue by adding `_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY` which is used to mark externally instantiated member functions as always inline. When building the library `_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY` sets the symbol's visibility to "default" instead of "hidden", otherwise it acts exactly the same as `_LIBCPP_INLINE_VISIBILITY`.

[libc++] Add _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY to support GCC ABI compatibility Summary: GCC and Clang handle visibility attributes on the out-of-line definition of externally instantiated templates differently. For example in the reproducer below Clang will emit both 'foo' and 'bar' with default visibility while GCC only emits a non-hidden 'foo'. ``` // RUN: g++ -std=c++11 -shared -O3 test.cpp && sym_extract.py a.out // RUN: clang++ -std=c++11 -shared -O3 test.cpp && sym_extract.py a.out #define INLINE_VISIBILITY __attribute__((visibility("hidden"), always_inline)) template <class T> struct Foo { void foo(); void bar(); }; template <class T> void Foo<T>::foo() {} template <class T> inline INLINE_VISIBILITY void Foo<T>::bar() {} template struct Foo<int>; ``` This difference creates ABI incompatibilities between Clang and GCC built dylibs. Specifically GCC built dylibs lack definitions for various member functions of `basic_string`, `basic_istream`, `basic_ostream`, `basic_iostream`, and `basic_streambuf` (All of these types are externally instantiated). Surprisingly these missing symbols don't cause many problems because the functions are marked `always_inline` therefore the dylib definition is rarely needed. However when an out-of-line definition is required then GCC built dylibs will fail to link. For example [GCC built dylibs cannot build Clang](http://stackoverflow.com/questions/39454262/clang-build-errors). This patch works around this issue by adding `_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY` which is used to mark externally instantiated member functions as always inline. When building the library `_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY` sets the symbol's visibility to "default" instead of "hidden", otherwise it acts exactly the same as `_LIBCPP_INLINE_VISIBILITY`.

[libcxx] Remove _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY That macro has been defined to _LIBCPP_HIDE_FROM_ABI_AFTER_V1 for many weeks now, so we're actually replacing uses of it for uses of _LIBCPP_HIDE_FROM_ABI_AFTER_V1 directly. This should not change or break anything since the two macros are 100% equivalent, unless somebody is (incorrectly!) relying on _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY being defined. llvm-svn: 344641

inline _LIBCPP_HIDE_FROM_ABI_AFTER_V1
[libc++] Add _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY to support GCC ABI compatibility Summary: GCC and Clang handle visibility attributes on the out-of-line definition of externally instantiated templates differently. For example in the reproducer below Clang will emit both 'foo' and 'bar' with default visibility while GCC only emits a non-hidden 'foo'. ``` // RUN: g++ -std=c++11 -shared -O3 test.cpp && sym_extract.py a.out // RUN: clang++ -std=c++11 -shared -O3 test.cpp && sym_extract.py a.out #define INLINE_VISIBILITY __attribute__((visibility("hidden"), always_inline)) template <class T> struct Foo { void foo(); void bar(); }; template <class T> void Foo<T>::foo() {} template <class T> inline INLINE_VISIBILITY void Foo<T>::bar() {} template struct Foo<int>; ``` This difference creates ABI incompatibilities between Clang and GCC built dylibs. Specifically GCC built dylibs lack definitions for various member functions of `basic_string`, `basic_istream`, `basic_ostream`, `basic_iostream`, and `basic_streambuf` (All of these types are externally instantiated). Surprisingly these missing symbols don't cause many problems because the functions are marked `always_inline` therefore the dylib definition is rarely needed. However when an out-of-line definition is required then GCC built dylibs will fail to link. For example [GCC built dylibs cannot build Clang](http://stackoverflow.com/questions/39454262/clang-build-errors). This patch works around this issue by adding `_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY` which is used to mark externally instantiated member functions as always inline. When building the library `_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY` sets the symbol's visibility to "default" instead of "hidden", otherwise it acts exactly the same as `_LIBCPP_INLINE_VISIBILITY`.

[libcxx] Remove _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY That macro has been defined to _LIBCPP_HIDE_FROM_ABI_AFTER_V1 for many weeks now, so we're actually replacing uses of it for uses of _LIBCPP_HIDE_FROM_ABI_AFTER_V1 directly.

inline _LIBCPP_HIDE_FROM_ABI_AFTER_V1
[libc++] Add _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY to support GCC ABI compatibility Summary: GCC and Clang handle visibility attributes on the out-of-line definition of externally instantiated templates differently. For example in the reproducer below Clang will emit both 'foo' and 'bar' with default visibility while GCC only emits a non-hidden 'foo'. ``` // RUN: g++ -std=c++11 -shared -O3 test.cpp && sym_extract.py a.out // RUN: clang++ -std=c++11 -shared -O3 test.cpp && sym_extract.py a.out #define INLINE_VISIBILITY __attribute__((visibility("hidden"), always_inline)) template <class T> struct Foo { void foo(); void bar(); }; template <class T> void Foo<T>::foo() {} template <class T> inline INLINE_VISIBILITY void Foo<T>::bar() {} template struct Foo<int>; ``` This difference creates ABI incompatibilities between Clang and GCC built dylibs. Specifically GCC built dylibs lack definitions for various member functions of `basic_string`, `basic_istream`, `basic_ostream`, `basic_iostream`, and `basic_streambuf` (All of these types are externally instantiated). Surprisingly these missing symbols don't cause many problems because the functions are marked `always_inline` therefore the dylib definition is rarely needed. However when an out-of-line definition is required then GCC built dylibs will fail to link. For example [GCC built dylibs cannot build Clang](http://stackoverflow.com/questions/39454262/clang-build-errors). This patch works around this issue by adding `_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY` which is used to mark externally instantiated member functions as always inline. When building the library `_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY` sets the symbol's visibility to "default" instead of "hidden", otherwise it acts exactly the same as `_LIBCPP_INLINE_VISIBILITY`. After applying this patch GCC dylibs now contain: * `_ZNSt3__115basic_streambufIcNS_11char_traitsIcEEE7sungetcEv` * `_ZNSt3__115basic_streambufIwNS_11char_traitsIwEEE5gbumpEi` *

The only remaining difference is that _LIBCPP_TYPE_VIS_ONLY can be applied to templates whereas _LIBCPP_TYPE_VIS cannot (due to dllimport/dllexport not being allowed on templates).

[libcxx] Don't depend on availability markup to provide the streams in the dylib Whether an explicit instantiation declaration should be provided is not a matter of availability markup. This problem is exemplified by the fact that some tests were incorrectly marked as XFAIL when they should instead have been using the definition of streams from the headers, and hence passing, and that, regardless of whether visibility annotations are enabled. llvm-svn: 348436

#ifndef _LIBCPP_DO_NOT_ASSUME_STREAMS_EXPLICIT_INSTANTIATION_IN_DYLIB
[libc++] Fix and document visibility attributes for Clang, GCC and Windows. Summary: This patch fixes a number of problems with the visibility macros across GCC (on Unix) and Windows (DLL import/export semantics). All of the visibility macros are now documented under `DesignDocs/VisibilityMacros.rst`. Now I'll no longer forget the subtleties of each! This patch adds two new visibility macros: * `_LIBCPP_ENUM_VIS` for controlling the typeinfo of enum types. Only Clang supports this. * `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` for redefining visibility on explicit instantiation declarations. Clang and Windows require this. After applying this patch GCC only emits one -Wattribute warning opposed to 30+.

Add markup for libc++ dylib availability Libc++ is used as a system library on macOS and iOS (amongst others). In order for users to be able to compile a binary that is intended to be deployed to an older version of the platform, clang provides the availability attribute <https://clang.llvm.org/docs/AttributeReference.html#availability>_ that can be placed on declarations to describe the lifecycle of a symbol in the library. See docs/DesignDocs/AvailabilityMarkup.rst for more information. Differential Revision: https://reviews.llvm.org/D31739 llvm-svn: 302172
