Adopt let_else across the compiler This performs a substitution of code following the pattern: let <id> = if let <pat> = ... { identity } else { ... : ! }; To simplify it to: let <pat> = ... { identity } else { ... : ! }; By adopting the let_else feature. 2021-10-16 01:45:14 +00:00			`#![feature(let_else)]`

Stream the dep-graph to a file. 2021-03-02 21:38:49 +00:00			`use assert_dep_graph::assert_dep_graph;`
Change `WorkProduct::saved_files` to an `Option`. Because there is at most one file. 2020-05-12 05:56:02 +00:00			`pub use persist::copy_cgu_workproduct_to_incr_comp_cache_dir;`
Update naming in line with PR comments 2018-05-09 15:16:08 +00:00			`pub use persist::delete_workproduct_files;`
Implement copy-on-write scheme for managing the incremental compilation cache. 2016-08-11 23:02:39 +00:00			`pub use persist::finalize_session_directory;`
incr.comp.: Run cache directory garbage collection before loading dep-graph. 2018-02-13 12:37:32 +00:00			`pub use persist::garbage_collect_session_directories;`
Modify trans to skip generating `.o` files This checks the `previous_work_products` data from the dep-graph and tries to simply copy a `.o` file if possible. We also add new work-products into the dep-graph, and create edges to/from the dep-node for a work-product. 2016-07-21 16:49:59 +00:00			`pub use persist::in_incr_comp_dir;`
Persist ThinLTO import data in incr. comp. session directory. 2018-08-17 14:07:23 +00:00			`pub use persist::in_incr_comp_dir_sess;`

rustc: Remove `Session::dep_graph` This commit removes the `dep_graph` field from the `Session` type according to issue #44390. Most of the fallout here was relatively straightforward and the `prepare_session_directory` function was rejiggered a bit to reuse the results in the later-called `load_dep_graph` function. Closes #44390 2017-09-09 18:02:18 +00:00			`pub use persist::prepare_session_directory;`
