rustdoc: forward -Z options to rustc by tmiasko · Pull Request #65314 · rust-lang/rust

tmiasko · 2019-10-11T18:02:01Z

Currently rustdoc does not forward -Z options to rustc when building
test executables. This makes impossible to use rustdoc to run test
samples when crate under test is instrumented with one of sanitizers
-Zsanitizer=..., since the final linking step will not include
sanitizer runtime library.

Forward -Z options to rustc to solve the issue.

Helps with #43031.

Currently rustdoc does not forward `-Z` options to rustc when building test executables. This makes impossible to use rustdoc to run test samples when crate under test is instrumented with one of sanitizers `-Zsanitizer=...`, since the final linking step will not include sanitizer runtime library. Forward `-Z` options to rustc to solve the issue. Helps with rust-lang#43031.

I also ran into this issue, and this fix appears to help in my case of testing some unstable cargo/rustc interaction.
