2020-05-07Auto merge of #55617 - oli-obk:stacker, r=nagisa,oli-obkbors-0/+1
Prevent compiler stack overflow for deeply recursive code I was unable to write a test that 1. runs in under 1s 2. overflows on my machine without this patch The following reproduces the issue, but I don't think it's sensible to include a test that takes 30s to compile. We can now easily squash newly appearing overflows by the strategic insertion of calls to `ensure_sufficient_stack`. ```rust // compile-pass #![recursion_limit="1000000"] macro_rules! chain { (EE $e:expr) => {$e.sin()}; (RECURSE $i:ident $e:expr) => {chain!($i chain!($i chain!($i chain!($i $e))))}; (Z $e:expr) => {chain!(RECURSE EE $e)}; (Y $e:expr) => {chain!(RECURSE Z $e)}; (X $e:expr) => {chain!(RECURSE Y $e)}; (A $e:expr) => {chain!(RECURSE X $e)}; (B $e:expr) => {chain!(RECURSE A $e)}; (C $e:expr) => {chain!(RECURSE B $e)}; // causes overflow on x86_64 linux // less than 1 second until overflow on test machine // after overflow has been fixed, takes 30s to compile :/ (D $e:expr) => {chain!(RECURSE C $e)}; (E $e:expr) => {chain!(RECURSE D $e)}; (F $e:expr) => {chain!(RECURSE E $e)}; // more than 10 seconds (G $e:expr) => {chain!(RECURSE F $e)}; (H $e:expr) => {chain!(RECURSE G $e)}; (I $e:expr) => {chain!(RECURSE H $e)}; (J $e:expr) => {chain!(RECURSE I $e)}; (K $e:expr) => {chain!(RECURSE J $e)}; (L $e:expr) => {chain!(RECURSE L $e)}; } fn main() { let x = chain!(D 42.0_f32); } ``` fixes #55471 fixes #41884 fixes #40161 fixes #34844 fixes #32594 cc @alexcrichton @rust-lang/compiler I looked at all code that checks the recursion limit and inserted stack growth calls where appropriate.

2020-05-02Move ensure_sufficient_stack to data_structuresSimonas Kazlauskas-0/+1
We anticipate this to have uses in all sorts of crates and keeping it in `rustc_data_structures` enables access to it from more locations without necessarily pulling in the large `librustc` crate.

2019-11-12Move self-profile infrastructure to data structuresMark Rousskov-0/+2
The single dependency on queries (QueryName) can be fairly easily abstracted via a trait and this further decouples Session from librustc (the primary goal).

2019-07-07rustc: Remove `dylib` crate type from most rustc cratesAlex Crichton-2/+1
Now that procedural macros no longer link transitively to libsyntax, this shouldn't be needed any more! This commit is an experiment in removing all dynamic libraries from rustc except for librustc_driver itself. Let's see how far we can get with that!

The ena version has an improved interface. I suspect `librustc_data_structures` should start migrating out to crates.io in general.

2017-03-23Remove internal liblogAlex Crichton-1/+1
This commit deletes the internal liblog in favor of the implementation that lives on crates.io. Similarly it's also setting a convention for adding crates to the compiler. The main restriction right now is that we want compiler implementation details to be unreachable from normal Rust code (e.g. requires a feature), and by default everything in the sysroot is reachable via `extern crate`. The proposal here is to require that crates pulled in have these lines in their `src/lib.rs`: #![cfg_attr(rustbuild, feature(staged_api, rustc_private))] #![cfg_attr(rustbuild, unstable(feature = "rustc_private", issue = "27812"))] This'll mean that by default they're not using these attributes but when compiled as part of the compiler they do a few things: * Mark themselves as entirely unstable via the `staged_api` feature and the `#![unstable]` attribute. * Allow usage of other unstable crates via `feature(rustc_private)` which is required if the crate relies on any other crates to compile (other than std).
2017-02-03Bump version, upgrade bootstrapAlex Crichton-1/+0
This commit updates the version number to 1.17.0 as we're not on that version of the nightly compiler, and at the same time this updates src/stage0.txt to bootstrap from freshly minted beta compiler and beta Cargo.
