[cfe-dev] implemented a new switch, having trouble testing

[Daniel DeCovnick]

There's been a lot of discussion lately on the Apple objc-language list about how it'd be nice if there was a compiler switch to specify what class should be used for numeric, array, and dictionary literals, similar to -fconstant-string-class. So I went ahead and implemented -fobjc-numeric-literal-class (with -fobjc-array-literal-class and -fobjc-dictionary-literal-class to come)

The diff: http://pastie.org/3663039

Or at least I think I did. I'm not sure, because I haven't been able to test it properly. I tried to write a test case in SemaObjC based on the objc-literal-nsnumber test: 

http://pastie.org/3663058

but the test always fails, with this error: 
"error: 'error' diagnostics seen but not expected: 
 (frontend): unknown argument: '-fobjc-numeric-literal-class=MYNumber'" 

I also wrote a test program which seems to work correctly: http://pastie.org/3663088 (and gives the expected warning if I do @123.45 instead of @123.45f, as -numberWithDouble: isn't implemented on MYNumber)

Can someone help me get the test working, and then what's the process for getting a patch like this sent upstream (once I've got the array and dictionary literals done)?
