Fix spelling: Cannonical -> Canonical
2021-10-10Auto merge of #88952 - skrap:add-armv7-uclibc, r=nagisabors-2/+2
Add new tier-3 target: armv7-unknown-linux-uclibceabihf This change adds a new tier-3 target: armv7-unknown-linux-uclibceabihf This target is primarily used in embedded linux devices where system resources are slim and glibc is deemed too heavyweight. Cross compilation C toolchains are available [here](https://toolchains.bootlin.com/) or via [buildroot](https://buildroot.org). The change is based largely on a previous PR #79380 with a few minor modifications. The author of that PR was unable to push the PR forward, and graciously allowed me to take it over. Per the [target tier 3 policy](https://github.com/rust-lang/rfcs/blob/master/text/2803-target-tier-policy.md), I volunteer to be the "target maintainer". This is my first PR to Rust itself, so I apologize if I've missed things!

2021-10-09Auto merge of #89343 - Mark-Simulacrum:no-args-queries, r=cjgillotbors-36/+40
Refactor fingerprint reconstruction This PR replaces can_reconstruct_query_key with fingerprint_style, which returns the style of the fingerprint for that query. This allows us to avoid trying to extract a DefId (or equivalent) from keys which *are* reconstructible because they're () but not as DefIds. This is done with the goal of fixing -Zdump-dep-graph, which seems to have broken a while ago (I didn't try to bisect). Currently even on a `fn main() {}` file it'll ICE (you need to also pass -Zquery-dep-graph for it to work at all), and this patch indirectly fixes the cause of that ICE. This also adds a test for it continuing to work.

2021-10-08Auto merge of #89576 - tom7980:issue-89275-fix, r=estebankbors-4/+11
Prevent error reporting from outputting a recursion error if it finds an ambiguous trait impl during suggestions Closes #89275 This fixes the compiler reporting a recursion error during another already in progress error by trying to make a conversion method suggestion and encounters ambiguous trait implementations that can convert a the original type into a type that can then be recursively converted into itself via another method in the trait. Updated OverflowError struct to be an enum so I could differentiate between passes - it's no longer a ZST but I don't think that should be a problem as they only generate when there's an error in compiling code anyway
2021-10-08Auto merge of #89619 - michaelwoerister:incr-vtables, r=nagisabors-79/+70
Turn vtable_allocation() into a query This PR removes the untracked vtable-const-allocation cache from the `tcx` and turns the `vtable_allocation()` method into a query. The change is pretty straightforward and should be backportable without too much effort. Fixes https://github.com/rust-lang/rust/issues/89598.
2021-10-07Rollup merge of #89025 - ricobbe:raw-dylib-link-ordinal, r=michaelwoeristerJubilee-1/+1
Implement `#[link_ordinal(n)]` Allows the use of `#[link_ordinal(n)]` with `#[link(kind = "raw-dylib")]`, allowing Rust to link against DLLs that export symbols by ordinal rather than by name. As long as the ordinal matches, the name of the function in Rust is not required to match the name of the corresponding function in the exporting DLL. Part of #58713.

2021-10-07Auto merge of #89534 - camsteffen:diag-name, r=oli-obkbors-4/+9
Introduce `tcx.get_diagnostic_name` Introduces a "reverse lookup" for diagnostic items. This is mainly intended for `@rust-lang/clippy` which often does a long series of `is_diagnostic_item` calls for the same `DefId`. r? `@oli-obk`

2021-10-06Query the fingerprint style during key reconstructionMark Rousskov-36/+40
Keys can be reconstructed from fingerprints that are not DefPathHash, but then we cannot extract a DefId from them.

Move ICH to rustc_query_system Based on https://github.com/rust-lang/rust/pull/89183 The StableHashingContext does not need to be in rustc_middle. This PR moves it to rustc_query_system. This will avoid a dependency between rustc_ast_lowering and rustc_middle in https://github.com/rust-lang/rust/pull/89124.
2021-10-04Rollup merge of #89466 - Mark-Simulacrum:query-macros, r=oli-obkJubilee-5/+5
Fix bug with query modifier parsing The previous macro_rules! parsers failed when an additional modifier was added with ambiguity errors. The error is pretty unclear as to what exactly the cause here is, but this change simplifies the argument parsing code such that the error is avoided. Extracted from other work, and somewhat duplicates 0358edeb5 from #85830, but this approach seems a little simpler to me. Not technically currently necessary but seems like a good cleanup.

2021-10-03Rollup merge of #88481 - bjorn3:remove_feature_gates, r=cjgillotManish Goregaokar-9/+7
Remove some feature gates The first commit removes various feature gates that are unused. The second commit replaces some `Fn` implementations with `Iterator` implementations, which is much cleaner IMO. The third commit replaces an unboxed_closures feature gate with min_specialization. For some reason the unboxed_closures feature gate suppresses the min_specialization feature gate from triggering on an `TrustedStep` impl. The last comment just turns a regular comment into a doc comment as drive by cleanup. I can move it to a separate PR if preferred.

2021-10-02Auto merge of #89408 - Mark-Simulacrum:fix-query-nondet, r=petrochenkovbors-2/+23
Avoid nondeterminism in trimmed_def_paths Previously this query depended on the global interning order of Symbols, which meant that irrelevant changes could influence the query and cause recompilations. This commit ensures that the return set is stable and will not be affected by the global order by deterministically (in lexicographic order) choosing a name to use if there are multiple names for a single DefId. This should fix the cause of the [regressions] in #83343.

2021-10-01Rollup merge of #89441 - Nadrieril:fix-89393, r=tmandryManish Goregaokar-2/+2
Normalize after substituting via `field.ty()` Back in https://github.com/rust-lang/rust/issues/72476 I hadn't understood where the problem was coming from, and only worked around the issue. What happens is that calling `field.ty()` on a field of a generic struct substitutes the appropriate generics but doesn't normalize the resulting type. As a consumer of types I'm surprised that one would substitute without normalizing, feels like a footgun, so I added a comment. Fixes https://github.com/rust-lang/rust/issues/89393.

Rework HIR API to make invocations of the hir_crate query harder. `hir_crate` forces the recomputation of queries that depend on it. This PR aims at avoiding useless invocations of `hir_crate` by making dependent code go through `tcx.hir()`.
