2021-09-04Auto merge of #88550 - dpaoliello:dpaoliello/allocdebuginfo, r=estebankbors-41/+66
Include debug info for the allocator shim Issue Details: In some cases it is necessary to generate an "allocator shim" to forward various Rust allocation functions (e.g., `__rust_alloc`) to an underlying function (e.g., `malloc`). However, since this allocator shim is a manually created LLVM module it is not processed via the normal module processing code and so no debug info is generated for it (if debugging info is enabled). Fix Details: * Modify the `debuginfo` code to allow creating debug info for a module without a `CodegenCx` (since it is difficult, and expensive, to create one just to emit some debug info). * After creating the allocator shim add in basic debug info.

2021-09-04Auto merge of #88538 - bjorn3:no_session_in_crate_loader, r=petrochenkovbors-94/+77
CrateLocator refactorings This makes the `CrateLocator` a lot cleaner IMHO and much more self-contained. The last commit removes `extra_filename` from the crate metadata. This is an **insta-stable** change as it allows a crate like `libfoo-abc.rlib` to be used as dependency and then be renamed as `libfoo-bcd.rlib` while still being found as indirect dependency. This may reduce performance when there are a lot of versions of the same crate available as the extra filename won't be used to do an early rejection of crates before trying to load metadata, but it makes the logic to find the right filename a lot cleaner.

2021-09-03Auto merge of #88572 - matthewjasper:if-let-scoping-fix, r=oli-obkbors-115/+195
Fix drop handling for `if let` expressions MIR lowering for `if let` expressions is now more complicated now that `if let` exists in HIR. This PR adds a scope for the variables bound in an `if let` expression and then uses an approach similar to how we handle loops to ensure that we reliably drop the correct variables.

2021-09-03Auto merge of #88428 - petrochenkov:stmtid, r=Aaron1011bors-55/+83
expand: Treat more macro calls as statement macro calls This PR implements the suggestion from https://github.com/rust-lang/rust/pull/87981#issuecomment-906641052 and treats fn-like macro calls inside `StmtKind::Item` and `StmtKind::Semi` as statement macro calls, which is consistent with treatment of attribute invocations in the same positions and with token-based macro expansion model in general. This also allows to remove a special case in `NodeId` assignment (previously tried in #87779), and to use statement `NodeId`s for linting (`assign_id!`). r? `@Aaron1011`

Point at unclosed delimiters as part of the primary MultiSpan Both the place where the parser encounters a needed closed delimiter and the unclosed opening delimiter are important, so they should get the same level of highlighting in the output. _Context: https://twitter.com/mwk4/status/1430631546432675840_
2021-09-03Auto merge of #88363 - michaelwoerister:remapped-diagnostics, r=estebankbors-36/+63
Path remapping: Make behavior of diagnostics output dependent on presence of --remap-path-prefix. This PR fixes a regression (#87745) with `--remap-path-prefix` where the flag stopped causing diagnostic messages to be remapped as well. The regression was introduced in https://github.com/rust-lang/rust/pull/83813 where we erroneously assumed that remapping of diagnostic messages was not desired anymore (because #70642 partially undid that functionality with nobody objecting). The issue is fixed by making `--remap-path-prefix` remap diagnostic messages again, including for paths that have been remapped in upstream crates (e.g. the standard library). This means that "sysroot-localization" (implemented in #70642) is also disabled if `rustc` is invoked with `--remap-path-prefix`. The assumption is that once someone starts explicitly remapping paths they also don't want paths to their local Rust installation in their build output. In the future we might want to give more fine-grained control over this behavior via compiler flags (see https://github.com/rust-lang/rfcs/pull/3127 for a related RFC). For now this PR is intended as a regression fix. This PR is an alternative to https://github.com/rust-lang/rust/pull/88191, which makes diagnostic messages be remapped unconditionally. That approach, however, would effectively revert #70642. Fixes https://github.com/rust-lang/rust/issues/87745. cc `@cbeuw` r? `@ghost`
2021-09-02Auto merge of #85868 - Aaron1011:projection-cache, r=jackh726bors-50/+29
Preserve most sub-obligations in the projection cache Fixes https://github.com/rust-lang/rust/issues/85360 When we evaluate a projection predicate, we may produce sub-obligations. During trait evaluation, evaluating these sub-obligations might cause us to produce `EvaluatedToOkModuloRegions`. When we cache the result of projection in our projection cache, we try to throw away some of the sub-obligations, so that we don't need to re-evaluate/process them the next time we need to perform this particular projection. However, we may end up throwing away predicates that will (recursively) evaluate to `EvaluatedToOkModuloRegions`. If we do, then the result of evaluating a predicate will depend on the state of the predicate cache - this is global untracked state, which interacts badly with incremental compilation. To fix this, we now only discard global predicates that evaluate to `EvaluatedToOk`. This ensures that any predicates that (may) evaluate to `EvaluatedToOkModuloRegions` are kept in the cache, and influence the results of any queries which perform this projection.

2021-09-02Rollup merge of #88567 - camelid:query-job-info, r=cjgillotMara Bos-11/+8
Remove redundant `Span` in `QueryJobInfo` Previously, `QueryJobInfo` was composed of two parts: a `QueryInfo` and a `QueryJob`. However, both `QueryInfo` and `QueryJob` have a `span` field, which seem to be the same. So, the `span` was recorded twice. Now, `QueryJobInfo` is composed of a `QueryStackFrame` (the other field of `QueryInfo`) and a `QueryJob`. So, now, the `span` is only recorded once.
