Reland "Use custom command and target to install libc++ headers" Using file(COPY FILE...) has several downsides. Since the file command is only executed at configuration time, any changes to headers made after the initial CMake execution are ignored. This can lead to subtle errors since the just built Clang will be using stale libc++ headers. Furthermore, since the headers are copied prior to executing the build system, this may hide missing dependencies on libc++ from other LLVM components. This changes replaces the use of file(COPY FILE...) command with a custom command and target which addresses all aforementioned issues and matches the implementation already used by other LLVM components that also install headers like Clang builtin headers.

[libc++] Rework the whole availability markup implementation Currently, vendor-specific availability markup is enabled by default. This means that even when building against trunk libc++, the headers will by default prevent you from using some features that were not released in the dylib on your target platform. This is a source of frustration since people building libc++ from sources are usually not trying to use some vendor's released dylib. For that reason, I've been thinking for a long time that availability annotations should be off by default, which is the primary change that this commit enables. In addition, it reworks the implementation to make it easier for new vendors to add availability annotations for their platform, and it refreshes the documentation to reflect the current state of the codebase. Finally, a CMake configuration option is added to control whether availability annotations should be turned on for the flavor of libc++ being created. The intent is for vendors like Apple to turn it on, and for the upstream libc++ to leave it off (the default). Differential Revision: https://reviews.llvm.org/D90843

[libc++] Include <__config_site> from <__config> Prior to this patch, we would generate a fancy <__config> header by concatenating <__config_site> and <__config>. This complexifies the build system and also increases the difference between what's tested and what's actually installed. This patch removes that complexity and instead simply installs <__config_site> alongside the libc++ headers. <__config_site> is then included by <__config>, which is much simpler. Doing this also opens the door to having different <__config_site> headers depending on the target, which was impossible before. It does change the workflow for testing header-only changes to libc++. Previously, we would run `lit` against the headers in libcxx/include. After this patch, we run it against a fake installation root of the headers (containing a proper <__config_site> header). This makes use closer to testing what we actually install, which is good, however it does mean that we have to update that root before testing header changes. Thus, we now need to run `ninja check-cxx-deps` before running `lit` by hand. Differential Revision: https://reviews.llvm.org/D97572

[libc++] Take 2: Integrate the PSTL into libc++ Summary: This commit allows specifying LIBCXX_ENABLE_PARALLEL_ALGORITHMS when configuring libc++ in CMake. When that option is enabled, libc++ will assume that the PSTL can be found somewhere on the CMake module path, and it will provide the C++17 parallel algorithms based on the PSTL (that is assumed to be available). The commit also adds support for running the PSTL tests as part of the libc++ test suite. The first attempt to commit this failed because it exposed a bug in the tests for modules. Now that this has been fixed, it should be safe to commit this.

[SystemZ][ZOS] Provide CLOCK_MONOTONIC alternative We need CLOCK_MONOTONIC equivalent implementation for z/OS within libc++. The default implementation is asserting. On z/OS the lack of 'clock_gettime()' and 'time_point()' force us to look for alternatives. The current proposal is to use `gettimeofday()` for CLOCK_MONOTONIC which is also used in CLOCK_REALTIME. This will allow us to skip the assertion with compromised CLOCK_MONOTONIC implementation which will not guarantee to never go back in time because it will use `gettimeofday()` but only when it's set. Is this a good compromise for platforms which does not support monotonic clock? Hopefully this will spark the discussion and agreement how to proceed in this situation.

[libc++] Include <__config_site> from <__config> Prior to this patch, we would generate a fancy <__config> header by concatenating <__config_site> and <__config>. This complexifies the build system and also increases the difference between what's tested and what's actually installed. This patch removes that complexity and instead simply installs <__config_site> alongside the libc++ headers. <__config_site> is then included by <__config>, which is much simpler. Doing this also opens the door to having different <__config_site> headers depending on the target, which was impossible before. It does change the workflow for testing header-only changes to libc++. Previously, we would run `lit` against the headers in libcxx/include. After this patch, we run it against a fake installation root of the headers (containing a proper <__config_site> header). This makes use closer to testing what we actually install, which is good, however it does mean that we have to update that root before testing header changes.

[libc++] Always generate a __config_site header Before this patch, the __config_site header was only generated when at least one __config_site macro needed to be defined. This lead to two different code paths in how libc++ is configured, depending on whether a __config_site header was generated or not. After this patch, the __config_site is always generated, but it can be empty in case there are no macros to define in it. More context on why this change is important -------------------------------------------- In addition to being confusing, this double-code-path situation lead to broken code being checked in undetected in 2405bd689815, which introduced the LIBCXX_HAS_MERGED_TYPEINFO_NAMES_DEFAULT CMake setting. Specifically, the _LIBCPP_HAS_MERGED_TYPEINFO_NAMES_DEFAULT <__config_site> macro was supposed NOT to be defined unless LIBCXX_HAS_MERGED_TYPEINFO_NAMES_DEFAULT was specified explicitly on the CMake command line. Instead, what happened is that it was defined to 0 if it wasn't specified explicitly and a <__config_site> header was generated. And defining that macro to 0 had the important effect of using the non-unique RTTI comparison implementation, which changes the ABI. This change in behavior wasn't noticed because the <__config_site> header is not generated by default. However, the Apple configuration does cause a <__config_site> header to be generated, which lead to the wrong RTTI implementation being used, and to https://llvm.org/PR45549. We came close to an ABI break in the dylib, but were saved due to a downstream-only change that overrode the decision of the <__config_site> for the purpose of RTTI comparisons in libc++abi. This is an incredible luck that we should not rely on ever again. While the problem itself was fixed with 2464d8135e2a by setting LIBCXX_HAS_MERGED_TYPEINFO_NAMES_DEFAULT explicitly in the Apple CMake cache and then in d0fcdcd28f95 by making the setting less brittle, the point still is that we should have had a single code path from the beginning. Unlike most normal libraries, the macros that configure libc++ are really complex, there's a lot of them and they control important properties of the C++ runtime. There must be a single code path for that, and it must be simple and robust. Differential Revision: https://reviews.llvm.org/D80927

Rather than copying libc++ headers into the build directory to be later overwritten by the final headers, use -isystem flag to access libc++ headers during CMake checks. This should address the occasional flake we've seen, especially on Windows builders where CMake fails to overwrite __config with the final version.

[CMake] Create a separate install target for libcxx headers This change doesn't impact the behavior of the install-libcxx target which installs whichever libcxx components you build, it just adds a separate target to just install the headers. llvm-svn: 268124

[libc++] Create install-stripped targets LLVM is gaining install-*-stripped targets to perform stripped installs, and in order for this to be useful for install-distribution, all potential distribution components should have stripped installation targets. LLVM has a function to create these install targets, but since we can't use LLVM CMake functions in libc++, let's do it manually.
