2022-05-03Rollup merge of #96587 - bjorn3:refactor_backend_write, r=michaelwoeristerYuki Okushi-11/+7
Refactor the WriteBackendMethods and ExtraBackendMethods traits The new interface is slightly less confusing and is easier to implement for non-LLVM backends.

2022-04-25Auto merge of #95604 - nbdd0121:used2, r=petrochenkovbors-56/+231
Generate synthetic object file to ensure all exported and used symbols participate in the linking Fix #50007 and #47384 This is the synthetic object file approach that I described in https://github.com/rust-lang/rust/pull/95363#issuecomment-1079932354, allowing all exported and used symbols to be linked while still allowing them to be GCed.

2022-04-18ssa: don't pack debuginfo on windows not only msvcDavid Wood-1/+1
Small fix that prevents `thorin` from running on platforms where it definitely shouldn't be running. Signed-off-by: David Wood <david.wood@huawei.com>

`CRATE_DEF_ID` and `CrateNum::as_def_id` are almost always what we want.
2022-04-13errors: lazily load fallback fluent bundleDavid Wood-1/+1
Loading the fallback bundle in compilation sessions that won't go on to emit any errors unnecessarily degrades compile time performance, so lazily create the Fluent bundle when it is first required. Signed-off-by: David Wood <david.wood@huawei.com>
2022-04-08check_doc_keyword: don't alloc string for emptiness checkklensy-2/+2
check_doc_alias_value: get argument as Symbol to prevent needless string convertions check_doc_attrs: don't alloc vec, iterate over slice. Vec introduced in #83149, but no perf run posted on merge replace as_str() check with symbol check get_single_str_from_tts: don't prealloc string trivial string to str replace LifetimeScopeForPath::NonElided use Vec<Symbol> instead of Vec<String> AssertModuleSource use BTreeSet<Symbol> instead of BTreeSet<String> CrateInfo.crate_name replace FxHashMap<CrateNum, String> with FxHashMap<CrateNum, Symbol>
2022-04-05errors: implement fallback diagnostic translationDavid Wood-5/+15
This commit updates the signatures of all diagnostic functions to accept types that can be converted into a `DiagnosticMessage`. This enables existing diagnostic calls to continue to work as before and Fluent identifiers to be provided. The `SessionDiagnostic` derive just generates normal diagnostic calls, so these APIs had to be modified to accept Fluent identifiers. In addition, loading of the "fallback" Fluent bundle, which contains the built-in English messages, has been implemented. Each diagnostic now has "arguments" which correspond to variables in the Fluent messages (necessary to render a Fluent message) but no API for adding arguments has been added yet. Therefore, diagnostics (that do not require interpolation) can be converted to use Fluent identifiers and will be output as before.
2022-04-05errors: introduce `DiagnosticMessage`David Wood-2/+2
Introduce a `DiagnosticMessage` type that will enable diagnostic messages to be simple strings or Fluent identifiers. `DiagnosticMessage` is now used in the implementation of the standard `DiagnosticBuilder` APIs. Signed-off-by: David Wood <david.wood@huawei.com>

2022-03-03Rollup merge of #94433 - Urgau:check-cfg-allowness, r=petrochenkovDylan DPC-1/+2
Improve allowness of the unexpected_cfgs lint This pull-request improve the allowness (`#[allow(...)]`) of the `unexpected_cfgs` lint. Before this PR only crate level `#![allow(unexpected_cfgs)]` worked, now with this PR it also work when put around `cfg!` or if it is in a upper level. Making it work ~for the attributes `cfg`, `cfg_attr`, ...~ for the same level is awkward as the current code is design to give "Some parent node that is close to this macro call" (cf. https://doc.rust-lang.org/nightly/nightly-rustc/rustc_expand/base/struct.ExpansionData.html) meaning that allow on the same line as an attribute won't work. I'm note even sure if this would be possible. Found while working on https://github.com/rust-lang/rust/pull/94298. r? ````````@petrochenkov````````
