如何查找llvm-*命令是否正在clang中使用
我已经在我的Debian系统上安装了clang和gcc。我想试试叮当声，然后给了她一个惊喜 下面的命令。从输出来看，似乎clang使用的gcc比 就在前端。如何确认clang实际使用的是llvm as、llvm ld和 编译此简单程序时使用其他llvm命令？我已经安装了大部分llvm-* 命令。谢谢你提供的任何信息如何查找llvm-*命令是否正在clang中使用,clang,Clang,我已经在我的Debian系统上安装了clang和gcc。我想试试叮当声，然后给了她一个惊喜 下面的命令。从输出来看，似乎clang使用的gcc比 就在前端。如何确认clang实际使用的是llvm as、llvm ld和 编译此简单程序时使用其他llvm命令？我已经安装了大部分llvm-* 命令。谢谢你提供的任何信息 clang -v c.c Debian clang version 3.0-6 (tags/RELEASE_30/final) (based on LLVM 3.0) Target:
