[cfe-dev] About the “unknown argumnet” Error in developping with clang

[redder_0210]

Dear All，
I'm trying to add a command lineoption to Clang/Clang++.
        What I have done is that I have modified the driver of Clang.. But the compilation instance(perhaps named clang cc1) of Clang cannot identify the new option. And the console prints the ERROR:" unknown argumnet".
       what's more,  when I have add the new command line argumnet to the "CC1Options.td", the console prints the "ast infomation"(in my opinion) of the source File. I have no idea about the reason.
       What operation should I do on the Clang now?
Thanks in advance.
       ------Redder.
