Subject: Allow "source_filename" to be an optional argument (the client can provide NULL)... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4633d1b26949346b6c0e707f76b899c79948b592;p=clang

Allow "source_filename" to be an optional argument (the client can provide NULL).  This allows the client to put the source_filename in the command_line_args without fear of the file being named twice.
