Subject: No longer allow the -std options to entirely override the -x language option. This... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0d936db44e95b1b5b825ee3517a3fa3a9e2f5a3f;p=clang

No longer allow the -std options to entirely override the -x language option. This allows -x cuda -std=c++11, for instance.
