Build distribution artifacts
You might want to build and package up the compiler for distribution. You’ll want to run this command to do it:
./x.py dist
Install distribution artifacts
If you’ve built a distribution artifact you might want to install it and test that it works on your target system. You’ll want to run this command:
./x.py install
Note: If you are testing out a modification to a compiler, you might want to use it to compile some project. Usually, you do not want to use ./x.py install for testing. Rather, you should create a toolchain as discussed in here.
For example, if the toolchain you created is called foo, you
would then invoke it with rustc +foo ...
(where ... represents
the rest of the arguments).
