* Update more file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | | 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++] Account for Microsoft CRT const overloadsShoaib Meenai2017-09-151-0/+4
| | | | | | | | | | Microsoft's CRT already provides the const overloads, and it defines the `_CRT_CONST_CORRECT_OVERLOADS` macro to indicate their presence. Check for this macro before attempting to define our own const-correct overloads, to avoid compiler warnings about casts dropping const qualifiers. llvm-svn: 313377

* [libc++] Refactor Windows support headers.Eric Fiselier2017-05-101-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch refactors and tries to remove as much of the Windows support headers as possible. This is needed because they currently introduce super weird include cycles and dependencies between STL and libc headers. The changes in this patch are: * remove `support/win32/support.h` completely. The required parts have either been moved into `support/win32/msvc_support.h` (for `MSVC` only helpers not needed by Clang), or directly into their respective `foo.h` headers. * Combine `locale_win32.h` and `locale_mgmt_win32.h` into a single headers, this header should only be included within `__locale` or `locale` to avoid include cycles. * Remove the unneeded parts of `limits_win32.h` and re-name it to `limits_msvc_win32.h` since it's only needed by Clang. I've tested this patch using Clang on Windows, but I suspect it might technically regress our non-existent support for MSVC. Is somebody able to double check? This refactor is needed to support upcoming fixes to `<locale>` on Windows.

* Fix overload sets of strchr, strpbrk, strrchr, memchr and strstr fromRichard Smith2016-02-101-1/+40
| | | | | | | | | | | | | | | | | <string.h> and wcschr, wcspbrk, wcsrchr, wmemchr, and wcsstr from <wchar.h> to provide a const-correct overload set even when the underlying C library does not. This change adds a new macro, _LIBCPP_PREFERRED_OVERLOAD, which (if defined) specifies that a given overload is a better match than an otherwise equally good function declaration without the overload. This is implemented in modern versions of Clang via __attribute__((enable_if)), and not elsewhere. We use this new macro to define overloads in the global namespace for these functions that displace the overloads provided by the C library, unless we believe the C library is already providing the correct signatures. llvm-svn: 260337
