How to select the target platform in clang?

Question

Currently, I am using the command:

clang++ -o hello.exe hello.cpp

Is there any way to set the target platform, for example if I wanted to build targeting x86 or ARM on my x64 computer. In visual studio, you can easily set this under configurations. I am using clang front end and LLVM back end.

According to clang --help:

--target=<value> Generate code for the given target

In order to check which targets are available with your distribution of clang:

clang -print-targets

So for example, you can do:

clang++ --target=arm64 -o hello.exe hello.cpp
