2020-09-14[pstl] Support Threading Building Blocks 2020 (oneTBB) for "tbb" parallel ↵Dvorskiy, Mikhail1-79/+369
backend. After the changes the "tbb" parallel backend will work with old TBB versions(TBB_INTERFACE_VERSION <= 12000) and new ones (TBB 2020 and greater) More about oneTBB: https://github.com/oneapi-src/oneTBB Phabricator Review: https://reviews.llvm.org/D87380
2020-07-29[libc++][pstl] Remove c++98 from UNSUPPORTED annotationsLouis Dionne60-64/+64
c++98 isn't used by the test suite anymore, only c++03 is.
2020-07-22[CMake] Bump CMake minimum version to 3.13.4Louis Dionne1-1/+1
This upgrade should be friction-less because we've already been ensuring that CMake >= 3.13.4 is used. This is part of the effort discussed on llvm-dev here: http://lists.llvm.org/pipermail/llvm-dev/2020-April/140578.html Differential Revision: https://reviews.llvm.org/D78648

2020-07-08[pstl] Do not install the __config_site.in fileLouis Dionne1-1/+2
The generated version of the file is already installed -- we shouldn't install the pre-generation version of the file.
2020-07-08[pstl] Fix a few errors when running PSTL tests through the libc++ test suiteLouis Dionne3-23/+14
2020-05-18[pstl] A fix for move placement-new (and destroy) allocated objects from raw ↵Dvorskiy, Mikhail10-53/+507
memory. https://reviews.llvm.org/D74123 The fix affects follow algorithms: remove_if, unique, rotate, inplace_merge, partial_sort_copy, set_union, set_intersection, set_difference, set_symmetric_difference. For "is_trivial" types there are no problems with "creating objects/clean-up" For non-trivial types the algo results are also correct, but possible incorrect copying/moving "operator=" calls "by raw memory" within one of mentioned algo or incorrect destructor calls in the end of algo.
2020-04-15[pstl] Added missing double-underscore prefixes to some typesIsmail Pazarbasi1-7/+7
Summary: Some of the `move_` types were used with leading double-underscores, but they were declared without `__` prefix. This patch adds double-underscores to all `move_` types, and their uses.

2020-03-17[pstl] A hot fix for exclusive_scan (+ lost enable_if in declaration)Mikhail Dvorskiy3-6/+52
It fixes an ambiguity issue in case of a user has a custom policy and calls a version of exclusive_scan with binary operation. Differential Revision: https://reviews.llvm.org/D62719

2020-03-05[pstl] A cleanup fix for sort parallel algorithm.Dvorskiy, Mikhail1-114/+62
When one of sub-ranges has not been move constructed into a raw buffer, we should not call clean up for that sub-range. Instead of store detailed info about raw buffer history, the fix does the cleanup a sub-range after each moving the sub-range back. https://reviews.llvm.org/D73779
2020-02-24[arcconfig] Delete subproject arcconfigsShoaib Meenai1-4/+0
From https://secure.phabricator.com/book/phabricator/article/arcanist_new_project/: > An .arcconfig file is a JSON file which you check into your project's root. I've done some experimentation, and it looks like the subproject .arcconfigs just get ignored, as the documentation says. Given that we're fully on the monorepo now, it's safe to remove them.

2019-08-13[pstl] Allow customizing whether per-TU insulation is providedLouis Dionne22-0/+94
Like we do in libc++, PSTL needs the ability to constrain ABI-unstable symbols to each translation unit. This is OFF by default (like for libc++), because most people don't care about this and there is a cost associated to enabling the option (code bloat because templates are not deduped across TUs). I'm using '#pragma clang attribute push' to avoid marking each declaration with an attribute, which quickly becomes difficult to maintain. llvm-svn: 368684
2019-08-13[pstl] Rename PARALLELSTL_BACKEND to PSTL_PARALLEL_BACKENDLouis Dionne2-6/+6
It makes more sense to name configuration options as PSTL_XXX. Also, I'm naming it PSTL_PARALLEL_BACKEND because we might introduce the ability to customize the vectorization backend, in which case PSTL_BACKEND would become ambiguous. llvm-svn: 368672
2019-08-08[NFC][pstl] Run clang-formatLouis Dionne1-39/+38
We really need to do that consistently when applying patches. llvm-svn: 368312

llvm-svn: 368302
2019-08-08[pstl] Error out when the backend is left unspecifiedLouis Dionne1-3/+1
Instead of silently falling back to the serial backend, it's better if we fail loudly when the parallel backend is left unspecified. Since we have a __pstl_config_site header, a backend should always be specified. llvm-svn: 368285
2019-08-08[pstl] Add a __pstl_config_site header to record the CMake configurationLouis Dionne3-2/+28
This commit adds a __pstl_config_site header that contains the value of macros specified at CMake configuration time. It works similarly to libc++'s __config_site header, except we always include it as a separate file instead of concatenating it to the main configuration header. It is necessary to thread the includes for that header into libc++'s lit configuration, otherwise we'd be requiring an installation step prior to running the test suite. llvm-svn: 368284
2019-08-07[pstl] Make sure we install all of PSTL's include/ directoryLouis Dionne1-1/+1
We want to install files directly in include/, not only in include/pstl. llvm-svn: 368203
2019-08-06[pstl][libc++] Provide uglified header names for interface headersLouis Dionne4-0/+60
For the few (currently four) headers that make up the PSTL's interface to other Standard Libraries, provide a stable uglified header file that can be included by those Standard Libraries. We can then more easily change the internal organization of the PSTL without having to change the integration with Standard Libraries. llvm-svn: 368088

2019-08-05[libc++] Take 2: Integrate the PSTL into libc++Louis Dionne1-0/+2
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.

2019-07-31[pstl] Fully qualify pstl names.Eric Fiselier3-404/+401
Previously the code used "using namespace __pstl;" at block scope to introduce these names. This could cause conflicts with names defined by the standard library. So we should fully qualify them instead. llvm-svn: 367468

This is a stopgap measure to make it easier to integrate the PSTL into libc++. In the future, we should have a system similar to what libc++ does, where we specify settings at configuration time and generate a __config_site header that is part of the PSTL. llvm-svn: 363958

- unused parameter warnings - don't use single-letter template parameter names, like we do in libc++ - sign-comparison warnings - unused variables in the tests - unused local typedefs in the tests - the use of #include_next - field reordering in the tests - unused lambda captures Note that the rationale for why the static_casts to unsigned are OK is that last - first must always be non-negative, since [first, last) is a valid range. llvm-svn: 362148
