Subject: Remove useless parameter "WantFile" from Driver::GetProgramPath().
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b16488c9fbc5b1a846757c679de1761ff1486265;p=platform%2Fupstream%2Fllvm.git

Remove useless parameter "WantFile" from Driver::GetProgramPath().
This parameter is useless because nowhere used explicitly and always
gets its default value - "false".

The patch reviewed by Rafael Espindola.
