Subject: Pass ProgramStateRef by reference.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=443488eba94bf3504d2abee5cb5e8896f8cc212a;p=platform%2Fupstream%2Fllvm.git

Pass ProgramStateRef by reference.

Retain + Release on a ref counted pointer is cheap, but not free (it adds a function call in this case).
