Subject: Pass ProgramStateRef by reference.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1831bd29572b6a7243da73d9606209190c0217de;p=clang

Pass ProgramStateRef by reference.

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