incr compilation struct_defs.rs
I am prematurely openeing this as I need mentoring help from @michaelwoerister (also pinged @nikomatsakis)
First, is this the right approach for these changes?
Second, I'm a bit confused by the results so far.
- Changing `TupleStructFieldType(i32)` -> `...(u32)` changes only Hir and HirBody, not TypeOfItem
- Chaning `TupleStructAddField(i32)` -> `...(i32, u32)` *does* change TypeOfItem
This seems wrong. I feel like it should change TypeOfItem in both cases. Is this a bug in incr compilation or is it expected?
Initial support for `..=` syntax
#28237
This PR adds `..=` as a synonym for `...` in patterns and expressions.
Since `...` in expressions was never stable, we now issue a warning.

Add ..= to the parser
Add ..= to libproc_macro
Add ..= to ICH
Highlight ..= in rustdoc
Update impl Debug for RangeInclusive to ..=
Replace `...` to `..=` in range docs
Make the dotdoteq warning point to the ...
Add warning for ... in expressions
Updated more tests to the ..= syntax
Updated even more tests to the ..= syntax
Updated the inclusive_range entry in unstable book
- Don't hash traits in scope as part of HIR hashing any more.
- Some queries returned DefIndexes from other crates.
- Provide a generic way of stably hashing maps (not used everywhere yet).
incr.comp.: Don't include span information in the ICH of type definitions
This should improve some of the `regex` tests on perf.rlo. Not including spans into the ICH is harmless until we also cache warnings. To really solve the problem, we need to do more refactoring (see #43088).
r? @nikomatsakis
Instead of collecting all potential inputs to some metadata entry and
hashing those, we directly hash the values we are storing in metadata.
This is more accurate and doesn't suffer from quadratic blow-up when
many entries have the same dependencies.
Stabilize static lifetime in statics
Stabilize the "static_in_const" feature. Blockers before this PR can be merged:
* [x] The [FCP with inclination to stabilize](https://github.com/rust-lang/rust/issues/35897#issuecomment-270441437) needs to be over. FCP lasts roughly three weeks, so will be over at Jan 25, aka this thursday.
* [x] Documentation needs to be added (#37928)
Closes#35897.
incr.comp.: Make cross-crate tracking for incr. comp. opt-in.
The current implementation of cross-crate dependency tracking can cause quite long compile times and high memory usage for some crates (see #39208 for example). This PR therefore makes that part of dependency tracking optional. Incremental compilation still works, it will only have very coarse dep-tracking for upstream crates.
