2019-04-30Rollup merge of #60276 - matthewjasper:cleanup-mir-visitor, r=estebankMazdak Farrokhzad-120/+59
Cleanup the MIR visitor * Remove useless `BasicBlock` parameters on methods with `Location`s. * Prefer `visit_terminator_kind` to `visit_terminator`. * Remove `Region` from PlaceContexts. `visit_rvalue` should be used when the region is important. * Remove unused visitor methods.

2019-04-26Auto merge of #60167 - varkor:tidy-filelength, r=matthewjasperbors-0/+2
Add a tidy check for files with over 3,000 lines Files with a large number of lines can cause issues in GitHub (e.g. https://github.com/rust-lang/rust/issues/60015) and also tend to be indicative of opportunities to refactor into less monolithic structures. This adds a new check to tidy to warn against files that have more than 3,000 lines, as suggested in https://github.com/rust-lang/rust/issues/60015#issuecomment-483868594. (This number was chosen fairly arbitrarily as a reasonable indicator of size.) This check can be ignored with `// ignore-tidy-filelength`. Existing files with greater than 3,000 lines currently ignore the check, but this helps us spot when files are getting too large. (We might try to split up all files larger than this in the future, as in https://github.com/rust-lang/rust/issues/60015).

Miri: refactor new allocation tagging Tagging and initializing `AllocExtra` now go hand-in-hand so one cannot forget to do one when doing the other. In particular, `memory.allocate` is now much easier to use correctly (because it will already return a tagged pointer). r? @oli-obk

2019-04-14Auto merge of #59693 - nnethercote:64-bit-Spans, r=petrochenkovbors-1/+1
Increase `Span` from 4 bytes to 8 bytes. This increases the size of some important types, such as `ast::Expr` and `mir::Statement`. However, it drastically reduces how much the interner is used, and the fields are more natural sizes that don't require bit operations to extract. As a result, instruction counts drop across a range of workloads, by as much as 10% for `script-servo` incremental builds. Peak memory usage goes up a little for some cases, but down by more for some other cases -- as much as 18% for non-incremental builds of `packed-simd`. The commit also: - removes the `repr(packed)`, because it has negligible effect, but can cause undefined behaviour; - replaces explicit impls of common traits (`Copy`, `PartialEq`, etc.) with derived ones. r? @petrochenkov

2019-04-03Rollup merge of #59630 - nnethercote:shrink-mir-Statement, r=pnkfelixMazdak Farrokhzad-17/+26
Shrink `mir::Statement`. The `InlineAsm` variant is extremely rare, and `mir::Statement` often contributes significantly to peak memory usage.
2019-04-03Rollup merge of #59514 - tmandry:remove-adt-def-from-projection-elem, r=eddybMazdak Farrokhzad-111/+87
Remove adt_def from projections and downcasts in MIR As part of optimizing generator layouts in MIR, we'd like to allow downcasting generators to variants which do not have a corresponding `def_id`, since they are created by the compiler. This refactor hopes to allow that, without regressing perf. r? @eddyb
