Various cleanups around pre-TyCtxt queries and functions part of #105462 based on https://github.com/rust-lang/rust/pull/106776 (everything starting at [0e2b39f](https://github.com/rust-lang/rust/pull/106810/commits/0e2b39fd1ffde51b50d45ccbe41de52b85136b8b) is new in this PR) r? `@petrochenkov` I think this should be most of the uncontroversial part of #105462.

2022-08-22Show absolute line numbers if span is outside relative spanNilstrieb-1/+1
In the MIR pretty printing, it can sometimes happen that the span of the statement is outside the span of the body (for example through inlining). In this case, don't display a relative span but an absolute span. This will make the mir-opt-tests a little more prone to diffs again, but the impact should be small.
2022-08-19Auto merge of #100209 - cjgillot:source-file-index, r=estebankbors-3/+2
Lazily decode SourceFile from metadata Currently, source files from foreign crates are decoded up-front from metadata. Spans from those crates were matched with the corresponding source using binary search among those files. This PR changes the strategy by matching spans to files during encoding. This allows to decode source files on-demand, instead of up-front. The on-disk format for spans becomes: `<tag> <position from start of file> <length> <file index> <crate (if foreign file)>`.

2022-06-01Lazify `SourceFile::lines`.Nicholas Nethercote-3/+10
`SourceFile::lines` is a big part of metadata. It's stored in a compressed form (a difference list) to save disk space. Decoding it is a big fraction of compile time for very small crates/programs. This commit introduces a new type `SourceFileLines` which has a `Lines` form and a `Diffs` form. The latter is used when the metadata is first read, and it is only decoded into the `Lines` form when line data is actually needed. This avoids the decoding cost for many files, especially in `std`. It's a performance win of up to 15% for tiny crates/programs where metadata decoding is a high part of compilation costs. A `Lock` is needed because the methods that access lines data (which can trigger decoding) take `&self` rather than `&mut self`. To allow for this, `SourceFile::lines` now takes a `FnMut` that operates on the lines slice rather than returning the lines slice.
2022-05-26Avoid adjusting file positions twice.Nicholas Nethercote-7/+14
`imported_source_files` adjusts lots of file positions, and then calls `new_imported_source_file`, which then adjust them all again. This commit combines the two adjustments into one, for a small perf win.

2021-09-03Auto merge of #88363 - michaelwoerister:remapped-diagnostics, r=estebankbors-6/+17
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`
2021-08-27Don't use `guess_head_span` in `predicates_of` for foreign spanAaron Hill-0/+11
Previously, the result of `predicates_of` for a foreign trait would depend on the *current* state of the corresponding source file in the foreign crate. This could lead to ICEs during incremental compilation, since the on-disk contents of the upstream source file could potentially change without the upstream crate being recompiled. Additionally, this ensure that that the metadata we produce for a crate only depends on its *compiled* upstream dependencies (e.g an rlib or rmeta file), *not* the current on-disk state of the upstream crate source files.
