[libc++] Rework compressed pair constructors.

2019-12-16T23:38:58+00:00

This patch de-duplicates most compressed pair constructors to use the same code in C++11 and C++03. Part of doing that is deleting the "__second_tag()" and replacing it with a "__value_init_tag()" which has the same effect, but allows for the removal of the special "one-arg" first element constructor. This patch is intended to have no semantic change.

[libc++] Cleanup and enable multiple warnings.

2019-12-13T02:09:08+00:00

Too many warnings are being disabled too quickly. Warnings are important to keeping libc++ correct. This patch re-enables two warnings: -Wconstant-evaluated and -Wdeprecated-copy. In future, all warnings disabled for the test suite should require an attached bug. The bug should state the plan for re-enabling that warning, or a strong case why it should remain disabled.

Rename __is_foo_iterator traits to reflect their Cpp17 nature.

2019-11-18T06:49:32+00:00

With the upcoming introduction of iterator concepts in ranges, the meaning of "__is_contiguous_iterator" changes drastically. Currently we intend it to mean "does it have this iterator category", but it could now also mean "does it meet the requirements of this concept", and these can be different.

Fix memory leak in set and map.

2019-07-11T23:13:38+00:00

When assigning an initializer list into set/map, libc++ would leak memory if the initializer list contained equivalent keys because we failed to check if the insertion was successful. llvm-svn: 365840

[libc++] Make sure we don't eagerly diagnose non-const comparators for containers of incomplete types

2019-04-11T16:14:56+00:00

Summary: In r348529, I improved the library-defined diagnostic for using containers with a non-const comparator/hasher. However, the check is now performed too early, which leads to the diagnostic being emitted in cases where it shouldn't. See PR41360 for details. This patch moves the diagnostic to the destructor of the containers, which means that the diagnostic will only be emitted when the container is instantiated at a point where the comparator and the key/value are required to be complete. We still retain better diagnostics than before r348529, because the diagnostics are performed in the containers themselves instead of __tree and __hash_table. As a drive-by fix, I improved the diagnostic to mention that we can't find a _viable_ const call operator, as suggested by EricWF in PR41360.

Update more file headers across all of the LLVM projects in the monorepo

2019-01-19T10:56:40+00:00

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++] Improve diagnostics for non-const comparators and hashers in associative containers

2018-12-06T21:46:17+00:00

Summary: When providing a non-const-callable comparator in a map or set, the warning diagnostic does not include the point of instantiation of the container that triggered the warning, which makes it difficult to track down the problem. This commit improves the diagnostic by placing it directly in the body of the associative container. The same change is applied to unordered associative containers, which had a similar problem. Finally, this commit cleans up the forward declarations of several map and unordered_map helpers, which are not needed anymore.

Second half of C++17's splicing maps and sets

2018-10-31T17:31:35+00:00

This commit adds a merge member function to all the map and set containers, which splices nodes from the source container. This completes support for P0083r3. Differential revision: https://reviews.llvm.org/D48896 llvm-svn: 345744
