New Revision: 327136
URL: http://llvm.org/viewvc/llvm-project?rev=327136&view=rev
Log:
[OPENMP] Fix the address of the original variable in task reductions.
If initialization of the task reductions requires pointer to original
variable, which is stored in the threadprivate storage, we used the
address of this pointer instead.
