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

[libc++] Add an option to disable wide character support in libc++ Some embedded platforms do not wish to support the C library functionality for handling wchar_t because they have no use for it. It makes sense for libc++ to work properly on those platforms, so this commit adds a carve-out of functionality for wchar_t. Unfortunately, unlike some other carve-outs (e.g. random device), this patch touches several parts of the library. However, despite the wide impact of this patch, I still think it is important to support this configuration since it makes it much simpler to port libc++ to some embedded platforms.

This change is orthogonal to the decision of what we're actually going to do with _LIBCPP_INLINE_VISIBILITY -- it just simplifies things by having one canonical way of doing things.

[libc++] Add an option to disable wide character support in libc++ Some embedded platforms do not wish to support the C library functionality for handling wchar_t because they have no use for it. It makes sense for libc++ to work properly on those platforms, so this commit adds a carve-out of functionality for wchar_t. Unfortunately, unlike some other carve-outs (e.g. random device), this patch touches several parts of the library. However, despite the wide impact of this patch, I still think it is important to support this configuration since it makes it much simpler to port libc++ to some embedded platforms.

[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

[libc++] Add an option to disable wide character support in libc++ Some embedded platforms do not wish to support the C library functionality for handling wchar_t because they have no use for it. It makes sense for libc++ to work properly on those platforms, so this commit adds a carve-out of functionality for wchar_t. Unfortunately, unlike some other carve-outs (e.g. random device), this patch touches several parts of the library. However, despite the wide impact of this patch, I still think it is important to support this configuration since it makes it much simpler to port libc++ to some embedded platforms.

[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
