[PATCH] D55959: [TSan] Enable detection of lock-order-inversions for Objective-C @synchronized

[Julian Lettner via Phabricator via llvm-commits]

yln updated this revision to Diff 179192.
yln added a comment.

Added test for recursive @synchronized blocks, that is, nested @synchronized on the same object. This tests proves lock recursiveness.

Directly `#include <objc/objc-sync.h>`. Had to change parameter type from `void *obj` to `id obj` in the interceptors to avoid `error: conflicting types for 'objc_sync_enter'`.
