2017-11-08std: Remove `rand` crate and moduleAlex Crichton-3/+5
This commit removes the `rand` crate from the standard library facade as well as the `__rand` module in the standard library. Neither of these were used in any meaningful way in the standard library itself. The only need for randomness in libstd is to initialize the thread-local keys of a `HashMap`, and that unconditionally used `OsRng` defined in the standard library anyway. The cruft of the `rand` crate and the extra `rand` support in the standard library makes libstd slightly more difficult to port to new platforms, namely WebAssembly which doesn't have any randomness at all (without interfacing with JS). The purpose of this commit is to clarify and streamline randomness in libstd, focusing on how it's only required in one location, hashmap seeds. Note that the `rand` crate out of tree has almost always been a drop-in replacement for the `rand` crate in-tree, so any usage (accidental or purposeful) of the crate in-tree should switch to the `rand` crate on crates.io. This then also has the further benefit of avoiding duplication (mostly) between the two crates!

2017-11-01Auto merge of #45472 - michaelwoerister:incr-comp-caching-base, r=nikomatsakisbors-2/+37
incr.comp.: Implement compiler diagnostic persistence. This PR implements storing and loading diagnostics that the compiler generates and thus allows for emitting warnings during incremental compilation without actually re-evaluating the thing the warning originally came from. It also lays some groundwork for storing and loading type information and MIR in the incr. comp. cache. ~~It is still work in progress:~~ - ~~There's still some documentation to be added.~~ - ~~The way anonymous queries are handled might lead to duplicated emissions of warnings. Not sure if there is a better way or how frequent such duplication would be in practice.~~ Diagnostic message duplication is addressed separately in #45519. r? @nikomatsakis

2017-10-21rustc: Move bytecode compression into codegenAlex Crichton-5/+9
This commit moves compression of the bytecode from the `link` module to the `write` module, namely allowing it to be (a) cached by incremental compilation and (b) produced in parallel. The parallelization may show up as some nice wins during normal compilation and the caching in incremental mode should be beneficial for incremental compiles! (no more need to recompress the entire crate's bitcode on all builds)

Incremental compilation auto assert (with except) cc @michaelwoerister bors merged part 1, so this is a WIP of part 2 of #45009 -- auto asserting DepNodes depending on the type of node rustc_clean/dirty is attached to Framework: - [x] finish auto-detection for specified DepNodes - [x] finish auto-detection for remaining DepNodes Test Refactors: - [x] consts.rs - [x] enum_constructors.rs - [x] extern_mods.rs - [x] inherent_impls.rs - [x] statics.rs - [x] struct_constructors.rs - ~~**BLOCKED** trait_defs.rs, see FIXME~~ - ~~**BLOCKED** trait_impls.rs~~ - [x] type_defs.rs - [x] enum_defs.rs

r=nikomatsakis incr.comp.: Bring back output of -Zincremental-info. This got kind lost during the transition to red/green. I also switched back from `eprintln!()` to `println!()` since the former never actually produced any output. I suspect this has to do with `libterm` somehow monopolizing `stderr`. r? @nikomatsakis
2017-10-12incr comp: rustc_clean/dirty auto assertGarrett Berg-28/+394
This adds auto-assertion to `rustc_clean/dirty` and also implements more comprehensive testing for - src/test/incremental/hashes/enum_constructors.rs - src/test/incremental/hashes/enum_defs.rs - src/test/incremental/hashes/extern_mods.rs - src/test/incremental/hashes/inherent_impls.rs - src/test/incremental/hashes/statics.rs - src/test/incremental/hashes/struct_constructors.rs - src/test/incremental/hashes/type_defs.rs trait_defs.rs and trait_impl.rs are blocked on a hard to triage compiler ICE (at least hard for a newbie like me) having to do with some DepNodes not getting computed for traits. A FIXME has been added in the source to reflect this continued work.
2017-10-08Auto merge of #44983 - vitiral:dirty_clean_groups, r=michaelwoeristerbors-12/+45
groundwork for rustc_clean/dirty improvements This is a WIP PR that needs mentoring from @michaelwoerister. There are several TODOs but no outstanding questions (except for the main one -- **is this the right approach?**) This is the plumbing for supporing groups in `rustc_clean(labels="...")`, as well as supporting an `except="..."` which will remove the excepted labels in the "clean" check and then assert that they are dirty (this is still TODO). See the code TODO's and example comments for a rough design. I'd like to know if this is the design you would like to do, and then I can go about actually filling out the groups and implementing the remaining logic.

2017-09-14rustc: Remove `Session::dep_graph`Alex Crichton-53/+50
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

2017-07-22rustc: Add some build scripts for librustc cratesAlex Crichton-0/+14
This commit adds some "boilerplate" build scripts to librustc/libsyntax crates to declare dependencies on various environment variables that are configured throughout the build. Cargo recently gained the ability to depend on environment variables in build scripts which can help trigger recompilation of a crate. This should fix weird bugs where after you make a commit or a few days later you'll get weird "not built with the same compiler" errors hopefully.
