Subject: Added `./x.py test --no-doc` option.
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=1733f5e1c0a69c853adebf718fc7b4f81a1d257b;p=rust.git

Added `./x.py test --no-doc` option.

This enables `./x.py test --stage 0 src/libstd --no-doc` and ensures the
stage2-rustc and rustdoc need to be built.
