@kennytm I have restricted the scope of this PR to only adding runtool functionality to rustdoc, along with Cargo in the other PR. |

Yes ignore is still a part of this PR, since being able to ignore on a per-target basis is relevant to using the crosscompilation feature. |

🤔 It's better to delegate the review to @rust-lang/rustdoc then, as it is changing the behavior of |

Sorry, how would that behavior change? |

@Goirad yeah that's what the "insta-stable" comment in #60387 (comment) is about. |

Just to be sure: shouldn't it be done over #63827 considering they'll make doctests run outside of rustdoc? |
|
This PR has been open for months, if @ollie27 is not available for review, can the docs team appoint a different reviewer? |
|
Sorry for the delay. As far as I'm concerned this feature and code looks good so r=me with a rebase. This could do with some tests like We also need tracking issues for the new features. |

Allow cross-compiling doctests This PR allows doctest to receive a --runtool argument, as well as possibly many --runtool-arg arguments, which are then used to run cross compiled doctests. Also, functionality has been added to rustdoc to allow it to skip testing doctests on a per-target basis, in the same way that compiletest does it. For example, tagging the doctest with "ignore-sgx" disables testing on any targets that contain "sgx". A plain "ignore" still skips testing on all targets. See [here](rust-lang/cargo#6892) for the companion PR in the cargo project that extends functionality in Cargo so that it passes the appropriate parameters to rustdoc when cross compiling and testing doctests.

Added ability to crosscompile doctests This commit adds the ability to cross-compile and run doctests. Like before cargo checks if target == host, the difference is that if there is a runtool defined in config.toml, it passes the information forward to rustdoc so that it can run the doctests with that tool. If no tool is defined and the target != host, cargo instead displays a message that doctests will not be compiled because of the missing runtool. See [here](rust-lang/rust#60387) for the companion PR in the rust project that modifies rustdoc to accept the relevant options as well as allow ignoring doctests on a per target level. Partially resolves [#6460](#6460) See [here](#7040) for the tracking issue.
