Can we port the extern prelude test to use this?
What about your existing tests for suggestions?
after some fiddling I've learned more about some implied things for @nikomatsakis is there a standard call for doing naming normalization (like the ones that make the output for a |

@alexcrichton is there a place on the compiler where I can get the official codepath that does this in a cross-platform way?

I think this can probably use std::env::consts::DLL_EXTENSION
perhaps? We typically don't need to factor in cross compilation here
I am very sad this hasn't landed yet. It would be very useful. |
Ping from triage @qmx, what is the status of this PR? |
closing this for now, will revisit it later |

this still doesn't have the definitive answer, but at least is a working start .

Ping from triage @qmx: It looks like this PR is failing on travis.
Thanks for the notice, sadly I don't have the time to work on the bot right now. |

Add options to --extern flag. This changes the `--extern` flag so that it can take a series of options that changes its behavior. The general syntax is `[opts ':'] name ['=' path]` where `opts` is a comma separated list of options. Two options are supported, `priv` which replaces `--extern-private` and `noprelude` which avoids adding the crate to the extern prelude. ```text --extern priv:mylib=/path/to/libmylib.rlib --extern noprelude:alloc=/path/to/liballoc.rlib ``` `noprelude` is to be used by Cargo's build-std feature in order to use `--extern` to reference standard library crates. This also includes a second commit which adds the `aux-crate` directive to compiletest. I can split this off into a separate PR if desired, but it helps with defining these kinds of tests. It is based on #54020, and can be used in the future to replace and simplify some of the Makefile tests.

When cargo exposes a crate to rustc, it uses
--extern
, with the potential for crate name aliasing. This PR adds this support to compiletest via aaux-crate:foo=baz.rs
header, where it exposes the cratebaz
under afoo
alias.This is specially useful for testing the new Rust 2018 edition module behaviors, since crates listed via
--extern
appear in the prelude.Additionally, this also adds some tests to the existing compiletest parsing code.
Fixes #53737
