In addition to covering the case where we would have previously updated `if_let_suggestions`, this might also prevent redundant errors in other cases as well. 2021-08-25T13:48:51+00:00 Léo Lanteri Thauvin leseulartichaut@gmail.com 2021-08-25T13:48:51+00:00 urn:sha1:f2cbbb93a2e0008f2907894ecd9fd9de3b39595b Remove `Session.trait_methods_not_found` Instead, avoid registering the problematic well-formed obligation to begin with. This removes global untracked mutable state, and avoids potential issues with incremental compilation. 2021-08-22T01:45:11+00:00 Aaron Hill aa1ronham@gmail.com 2021-08-21T23:45:56+00:00 urn:sha1:41f9f38d6e19c669a14432b9ec56f26425c6c9e2 Instead, avoid registering the problematic well-formed obligation to begin with.

As a side effect, we are to emit more detailed warning messages (instead of just a generic "unused" message). `Session.check_name` is removed, since its only purpose was to mark the attribute as used. All of the callers are modified to use `Attribute.has_name` Additionally, `AttributeType::AssumedUsed` is removed - an 'assumed used' attribute is implemented by simply not performing any checks in `CheckAttrVisitor` for a particular attribute. We no longer emit unused attribute warnings for the `#[rustc_dummy]` attribute - it's an internal attribute used for tests, so it doesn't mark sense to treat it as 'unused'. With this commit, a large source of global untracked state is removed. 2021-08-15T20:17:37+00:00 Aaron Hill aa1ronham@gmail.com 2021-08-12T20:30:40+00:00 urn:sha1:a895069c5023a82e9316d21854a81172c69d1418 Fixes #85019 A `SourceFile` created during compilation may have a relative path (e.g. if rustc itself is invoked with a relative path). When we write out crate metadata, we convert all relative paths to absolute paths using the current working direction. However, the working directory is not included in the crate hash. This means that the crate metadata can change while the crate hash remains the same. Among other problems, this can cause a fingerprint mismatch ICE, since incremental compilation uses the crate metadata hash to determine if a foreign query is green. This commit moves the field holding the working directory from `Session` to `Options`, including it as part of the crate hash. 2021-08-10T12:20:48+00:00 bjorn3 bjorn3@users.noreply.github.com 2021-05-14T13:37:53+00:00 urn:sha1:a501308ec1601c2b1d50230a061fb2700940727d 2021-08-06T16:46:32+00:00 Yuki Okushi jtitor@2k36.org 2021-08-06T16:46:32+00:00 urn:sha1:3b0e797ee6678175d1df9a01e944312b348d05b0 Fix overflow in rustc happening if the `err_count()` is reduced in a stage. This can happen if stashed diagnostics are removed or replaced with fewer errors. The semantics stay the same if built without overflow checks. Fixes #84219. Background: I came across this independently by running `RUSTFLAGS="-C overflow-checks=on" ./x.py test`. Fixing this will allow us to move on and find further overflow errors with testing or fuzzing.
