2019-01-07Revert "Auto merge of #57101 - o01eg:fix-57014, r=alexcrichton"Matthias Krüger-7/+0
This reverts commit 68614265d312fc2cbe8a696f7dabb9416eb6f221, reversing changes made to cae623c5ce12df8f237264d8f2c31fdaa664c382. Should fix tools on windows. Reopens #57014

2018-12-12Replace `FileSearch::for_each_lib_search_path` with `search_paths`.Nicholas Nethercote-23/+17
Returning an iterator leads to nicer code all around.
2018-12-12Avoid regenerating the `Vec<PathBuf>` in `FileSearch::search()`.Nicholas Nethercote-23/+11
`FileSearch::search()` traverses one or more directories. For each directory it generates a `Vec<PathBuf>` containing one element per file in that directory. In some benchmarks this occurs enough that the allocations done for the `PathBuf`s are significant, and in practice a small number of directories are being traversed over and over again. For example, when compiling the `tokio-webpush-simple` benchmark, two directories are traversed 58 times each. Each of these directories have more than 100 files. This commit changes things so that all the `Vec<PathBuf>`s that will be needed by a `Session` are precomputed when that `Session` is created; they are stored in `SearchPath`. `FileSearch` gets a reference to the necessary `SearchPath`s. This reduces instruction counts on several benchmarks by 1--5%. The commit also removes the barely-used `visited_dirs` hash in `for_each_lib_searchPath`. It only detects if `tlib_path` is the same as one of the previously seen paths, which is unlikely.
2018-12-12Introduce `SearchPath` and replace `SearchPaths` with `Vec<SearchPath>`.Nicholas Nethercote-16/+17
It's more idiomatic, makes the code shorter, and will help with the next commit.

The field init shorthand syntax was stabilized in 1.17.0 (aebd94f); we are now free to use it in the compiler.
