如何在Clang中获取支持的标准列表?
我在男人身上发现了这一点:如何在Clang中获取支持的标准列表?,clang,Clang,我在男人身上发现了这一点: -std=language Specify the language standard to compile for. -ansi Same as -std=c89. 但是在哪里可以找到我安装的编译器支持的所有标准的列表呢 clang -std=??? test.c 检查此文件:llvm.git/tools/clang/include/clang/Frontend/LangStandards.def 编译器支持的标准不断
-std=language
Specify the language standard to compile for.
-ansi
Same as -std=c89.
但是在哪里可以找到我安装的编译器支持的所有标准的列表呢
clang -std=??? test.c
检查此文件:llvm.git/tools/clang/include/clang/Frontend/LangStandards.def
编译器支持的标准不断变化,您可以检查此文件并自己尝试

如果用户没有为-std选项提供有效的标准名称,
将报告可用值(简短描述)
只需指定任何BS标准,clang将打印可接受的标准,如下所示:
c:\LLVM\bin>clang++.exe -std=blabla main.cpp
error: invalid value 'blabla' in '-std=blabla'
note: use 'c++98' or 'c++03' for 'ISO C++ 1998 with amendments' standard
note: use 'gnu++98' or 'gnu++03' for 'ISO C++ 1998 with amendments and GNU extensions' standard
note: use 'c++11' for 'ISO C++ 2011 with amendments' standard
note: use 'gnu++11' for 'ISO C++ 2011 with amendments and GNU extensions' standard
note: use 'c++14' for 'ISO C++ 2014 with amendments' standard
note: use 'gnu++14' for 'ISO C++ 2014 with amendments and GNU extensions' standard
note: use 'c++17' for 'ISO C++ 2017 with amendments' standard
note: use 'gnu++17' for 'ISO C++ 2017 with amendments and GNU extensions' standard
note: use 'c++2a' for 'Working draft for ISO C++ 2020' standard
note: use 'gnu++2a' for 'Working draft for ISO C++ 2020 with GNU extensions' standard
