Avoids a call to `traits::overlapping_impls`, which is expensive. 2020-02-06T20:58:01+00:00 Niko Matsakis niko@alum.mit.edu 2020-01-24T20:57:01+00:00 urn:sha1:363fabaf1fbd0f38a7ddde4a64866d8cd2cd49f2 2020-02-05T11:41:02+00:00 Camille GILLOT gillot.camille@gmail.com 2020-01-22T12:44:59+00:00 urn:sha1:c851db94951643c2b200b13bf6d8ab6d5fdb541e 2020-01-20T05:44:48+00:00 Dylan DPC dylan.dpc@gmail.com 2020-01-20T05:44:48+00:00 urn:sha1:fb86b820bbde7772477a95e36a70f06578313de2 Remove `rustc_error_codes` deps except in `rustc_driver` Remove dependencies on `rustc_error_codes` in all crates except for `rustc_driver`. This has some benefits: 1. Adding a new error code when hacking on the compiler only requires rebuilding at most `rustc_error_codes`, `rustc_driver`, and the reflexive & transitive closure of the crate where the new error code is being added and its reverse dependencies. This improves time-to-UI-tests (TTUT). 2. Adding an error description to an error code only requires rebuilding `rustc_error_codes` and `rustc_driver`. This should substantially improve TTUT. r? @petrochenkov cc @rust-lang/wg-diagnostics 2020-01-20T00:10:48+00:00 bors bors@rust-lang.org 2020-01-20T00:10:48+00:00 urn:sha1:29b854fb741809c29764e33fc17c32ba9c6523ba Don't discard marker trait impls when inference variables are present Fixes #61651 Previously, we would unconditionally discard impl candidates for marker traits during trait selection. However, if the predicate had inference variables, this could have the effect of constrainting inference variables (due to a successful trait selection) when we would have otherwise failed due to mutliple applicable impls, This commit prevents marker trait impls from being discarded while the obligation predicate has any inference variables, ensuring that discarding impls will never cause us to incorrectly constraint inference variables.
