如何獲取Clang中支持的標準列表？

Question

我發現這個在MAN：

-std=language 
     Specify the language standard to compile for. 

    -ansi 
     Same as -std=c89. 

但到哪裏去找我的編譯安裝所有支持的標準列表？

clang -std=??? test.c

檢查這個文件： llvm.git /工具/鐺/包括/鐺/前端/ LangStandards.def
online version from github
由編譯器所支持的不斷變化，你可以檢查這個文件的標準和親自嘗試一下。
