rust/compiler/rustc_query_system/src/dep_graph/query.rs, branch 1.58.0

Address review.

2021-03-30T16:10:08+00:00

Fix tests.

2021-03-30T16:10:06+00:00

Avoid invoking queries inside `check_paths`, since we are holding a lock to the reconstructed graph.

Stream the dep-graph to a file.

Remove (lots of) dead code

2021-03-28T02:16:33+00:00

Found with https://github.com/est31/warnalyzer. Dubious changes: - Is anyone else using rustc_apfloat? I feel weird completely deleting x87 support. - Maybe some of the dead code in rustc_data_structures, in case someone wants to use it in the future? - Don't change rustc_serialize I plan to scrap most of the json module in the near future (see https://github.com/rust-lang/compiler-team/issues/418) and fixing the tests needed more work than I expected. TODO: check if any of the comments on the deleted code should be kept.

rustc_query_system: use more space-efficient edges representation

2020-12-22T22:12:57+00:00

Use single vector of edges rather than per-node vector. There is a small hit to instruction counts (< 0.5%), but the memory savings make up for it.

rustc_query_system: share previous graph data with current graph

2020-12-22T22:12:57+00:00

Reduce memory consumption by taking advantage of red/green algorithm properties to share the previous dependency graph's node data with the current graph instead of storing node data redundantly. Red nodes can share the `DepNode`, and green nodes can share the `DepNode` and `Fingerprint`. Edges will be shared when possible in a later change.

Remove unused code from rustc_query_system
