clang - 如何获取Clang支持的标准列表？

Question

我在MAN中找到了这个:

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

   -ansi
       Same as -std=c89.

但是在哪里可以找到我已安装的编译器支持的所有标准的列表？

clang -std=??? test.c

检查此文件: llvm.git/tools/clang/include/clang/Frontend/LangStandards.def
online version from github
编译器支持的标准正在不断变化，您可以检查此文件并自己尝试。
