[libc++] Use _EnableIf instead of std::enable_if in deduction guides for map and set

2019-07-19T17:13:39+00:00

llvm-svn: 366594

Add contains method to associative containers. This patch implements P0458R2, adding contains to map, multimap, unordered_map, unordered_multimap, set, multiset, unordered_set, and unordered_multiset.

[libc++] Take 2: Implement CTAD for map and multimap

2019-06-20T19:32:00+00:00

This is a re-application of r362986 (which was reverted in r363688) with fixes for the issue that caused it to be reverted. Thanks to Arthur O'Dwyer for the patch. Differential Revision: https://reviews.llvm.org/D58587 llvm-svn: 363968

[libc++] Revert the addition of map/multimap CTAD

2019-06-18T14:40:15+00:00

This was found to be broken on Clang trunk. This is a revert of the following commits (the subsequent commits added XFAILs to the tests that were missing from the original submission): r362986: Implement deduction guides for map/multimap. r363014: Add some XFAILs r363097: Add more XFAILs r363197: Add even more XFAILs llvm-svn: 363688

Implement deduction guides for map/multimap. Reviewed as https://reviews.llvm.org/D58587. Thanks to Quuxplusone for the submission.

[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.

[libc++] Avoid UB in the no-exceptions mode in a few places

2019-02-12T16:06:02+00:00

Summary: A few places in the library seem to behave unexpectedly when the library is compiled or used with exceptions disabled. For example, not throwing an exception when a pointer is NULL can lead us to dereference the pointer later on, which is UB. This patch fixes such occurences. It's hard to tell whether there are other places where the no-exceptions mode misbehaves like this, because the replacement for throwing an exception does not always seem to be abort()ing, but at least this patch will improve the situation somewhat.

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.
