d714b9790b incr.comp.: Don't use Ident in DefPath because that's unstable across compilation sessions. 2017-06-13 13:47:13 +02:00

8b36d3308e Allocate DefIndices for global crate metadata. 
This allows for treating global crate metadata the same as regular metadata with regard to incr. comp.

c47cdc0d93 Introduce HashStable trait and base ICH implementations on it. 
This initial commit provides implementations for HIR, MIR, and
everything that also needs to be supported for those two.

090767b5ef Allocate numerical values of DefIndexes from two seperate ranges. 
This way we can have all item-likes occupy a dense range of
DefIndexes, which is good for making fast, array-based
dictionaries.

bc259ee844 Introduce HirId, a replacement for NodeId after lowering to HIR. 
HirId has a more stable representation than NodeId, meaning that
modifications to one item don't influence (part of) the IDs within
other items. The other part is a DefIndex for which there already
is a way of stable hashing and persistence.

This commit introduces the HirId type and generates a HirId for
every NodeId during HIR lowering, but the resulting values are
not yet used anywhere, except in consistency checks.

e1d4b8fc8c Use StableHasher everywhere 
The standard implementations of Hasher have architecture-dependent
results when hashing integers. This causes problems when the hashes are
stored within metadata - metadata written by one host architecture can't
be read by another.

To fix that, implement an architecture-independent StableHasher and use
it in all places an architecture-independent hasher is needed.

Fixes #38177.

10c3134da0 std: Stabilize and deprecate APIs for 1.13 
This commit is intended to be backported to the 1.13 branch, and works with the
following APIs:

Stabilized

* `i32::checked_abs`
* `i32::wrapping_abs`
* `i32::overflowing_abs`
* `RefCell::try_borrow`
* `RefCell::try_borrow_mut`
* `DefaultHasher`
* `DefaultHasher::new`
* `DefaultHasher::default`

Deprecated

* `BinaryHeap::push_pop`
* `BinaryHeap::replace`
* `SipHash13`
* `SipHash24`
* `SipHasher` - use `DefaultHasher` instead in the `std::collections::hash_map`
  module

Closes #28147
Closes #34767
Closes #35057
Closes #35070

2e7df80098 make metadata hashes determinstic 
When we hash the inputs to a MetaData node, we have to hash them in a
consistent order. We achieve this by sorting the stringfied `DefPath`
entries. Also, micro-optimie by cache more results across the saving
process.

b01919a144 allow retracing paths across crates 
For external crates, we must build up a map that goes from
the DefKey to the DefIndex. We do this by iterating over each
index that is found in the metadata and loading the associated
DefKey.
