DeLesley Hutchins e2a3f75a12 Thread safety analysis: expand set of expressions that can be used to denote locks. 
llvm-svn: 151956
 2012-03-02 23:36:05 +00:00

DeLesley Hutchins bc8ffdb68c Thread-Safety: added support for 'this' as a lock expression.

Richard Smith 922866783b Thread safety analysis: 
* When we detect that a CFG block has inconsistent lock sets, point the
   diagnostic at the location where we found the inconsistency, and point a note
   at somewhere the inconsistently-locked mutex was locked.
 * Fix the wording of the normal (non-loop, non-end-of-function) case of this
   diagnostic to not suggest that the mutex is going out of scope.
 * Fix the diagnostic emission code to keep a warning and its note together when
   sorting the diagnostics into source location order.

Richard Smith 815b29d7c9 Thread safety analysis: at a CFG join point between a block terminating in a 
'continue' and another block, prefer the lockset from the other block, and
diagnose the 'continue' block as being the end of a loop.
