[PATCH] D27409: [analyzer] RetainCountChecker: Improve support for libdispatch APIs.

[Artem Dergachev via Phabricator via cfe-commits]

NoQ retitled this revision from "[analyzer] RetainCountChecker: The callback in dispatch_data_create() doesn't free the return symbol." to "[analyzer] RetainCountChecker: Improve support for libdispatch APIs.".
NoQ updated the summary for this revision.
NoQ updated this revision to Diff 80432.
NoQ added a comment.

Add more tests.

Not sure we need to stay merged with `retain-release-arc.m`, as we're not really reusing many declarations across these files.

As well, handle the case when `dispatch_retain` and `dispatch_release` are regular functions.
