It adds a `const_loop` feature gate, which allows `while` and `loop` expressions through both HIR and MIR const-checkers if enabled. `for` expressions remain forbidden by the HIR const-checker, since they desugar to a call to `IntoIterator::into_iter`, which will be rejected anyways. `while` loops also require [`#![feature(const_if_match)]`](https://github.com/rust-lang/rust/pull/66507), since they have a conditional built into them. The diagnostics from the HIR const checker will suggest this to the user. r? @oli-obk cc @rust-lang/wg-const-eval 2019-12-14T14:01:09+00:00 Niko Matsakis niko@alum.mit.edu 2019-12-11T14:55:29+00:00 urn:sha1:d286113024ce50ada7a34f00041f4ff41f3217e6 This reverts commit 15c30ddd69d6cc3fffe6d304c6dc968a5ed046f1. 2019-12-13T18:39:14+00:00 Dylan MacKenzie ecstaticmorse@gmail.com 2019-12-11T18:09:10+00:00 urn:sha1:a2a077460b3365a95c475ce3b33fe7987c4bfa23 Conditionals and loops now have unstable features, and `feature_err` has its own error code. I think that `feature_err` should take an error code as a parameter, but don't have the energy to make this change throughout the codebase. Also, the error code system may be torn out entirely. 2019-12-09T11:17:38+00:00 Dylan DPC dylan.dpc@gmail.com 2019-12-09T11:17:38+00:00 urn:sha1:2183a949a8293eb328259374653e76199494b0ea 2019-12-09T02:09:36+00:00 ryan ryanswilson@protonmail.com 2019-12-09T02:09:36+00:00 urn:sha1:f430fca73a94dfcfff146dac8ea8833615fc537e 2019-12-06T22:26:54+00:00 Mazdak Farrokhzad twingoow@gmail.com 2019-12-06T22:26:54+00:00 urn:sha1:2bd35c065cb097d1ea6480c372ab9b5eea358cee Add feature gate for mut refs in const fn r? @oli-obk 2019-12-06T06:37:08+00:00 Yuki Okushi huyuumi.dev@gmail.com 2019-12-06T06:37:08+00:00 urn:sha1:662a225f1d251cd9f07e9c06a24094659a8c7242 cleanup long error explanations r? @Dylan-DPC 2019-12-06T06:37:06+00:00 Yuki Okushi huyuumi.dev@gmail.com 2019-12-06T06:37:06+00:00 urn:sha1:6c0165fa78c19a879b14f95b92b83d368ba6797c Add long error for E0631 and update ui tests. This PR adds a long error for `E0631`, which covers errors where closure argument types are mismatched. It also updates UI tests where this error is applicable.
