2017-11-24rustbuild: Update LLVM and enable ThinLTOAlex Crichton-0/+0
This commit updates LLVM to fix #45511 (https://reviews.llvm.org/D39981) and also reenables ThinLTO for libtest now that we shouldn't hit #45768. This also opportunistically enables ThinLTO for libstd which was previously blocked (#45661) on test failures related to debuginfo with a presumed cause of #45511. Closes #45511

2017-07-06rustc: Implement stack probes for x86Alex Crichton-0/+0
This commit implements stack probes on x86/x86_64 using the freshly landed support upstream in LLVM. The purpose of stack probes here are to guarantee a segfault on stack overflow rather than having a chance of running over the guard page already present on all threads by accident. At this time there's no support for any other architecture because LLVM itself does not have support for other architectures.
2017-07-05Switch to rust-lang-nursery/compiler-builtinsAlex Crichton-1163/+0
This commit migrates the in-tree `libcompiler_builtins` to the upstream version at https://github.com/rust-lang-nursery/compiler-builtins. The upstream version has a number of intrinsics written in Rust and serves as an in-progress rewrite of compiler-rt into Rust. Additionally it also contains all the existing intrinsics defined in `libcompiler_builtins` for 128-bit integers. It's been the intention since the beginning to make this transition but previously it just lacked the manpower to get done. As this PR likely shows it wasn't a trivial integration! Some highlight changes are: * The PR rust-lang-nursery/compiler-builtins#166 contains a number of fixes across platforms and also some refactorings to make the intrinsics easier to read. The additional testing added there also fixed a number of integration issues when pulling the repository into this tree. * LTO with the compiler-builtins crate was fixed to link in the entire crate after the LTO process as these intrinsics are excluded from LTO. * Treatment of hidden symbols was updated as previously the `#![compiler_builtins]` crate would mark all symbol *imports* as hidden whereas it was only intended to mark *exports* as hidden.

2017-04-24Auto merge of #40123 - TimNN:llvm40, r=alexcrichtonbors-0/+6
LLVM 4.0 Upgrade Since nobody has done this yet, I decided to get things started: **Todo:** * [x] push the relevant commits to `rust-lang/llvm` and `rust-lang/compiler-rt` * [x] cleanup `.gitmodules` * [x] Verify if there are any other commits from `rust-lang/llvm` which need backporting * [x] Investigate / fix debuginfo ("`<optimized out>`") failures * [x] Use correct emscripten version in docker image --- Closes #37609. --- **Test results:** Everything is green 🎉

Also update some 128 bit builtins to be panic-free without relying on the const evaluator.
2017-03-08Rollup merge of #40254 - nagisa:compiler-builtin-no-panic, r=alexcrichtonAriel Ben-Yehuda-4/+5
Fix personality_fn within the compiler_builtins compiler_builtins may not have any unwinding within it to link correctly. This is notoriously finicky, and this small piece of change removes yet another case where personality function happens to get introduced. Side note: I do remember solving the exact same thing before. I wonder why it has reappered... @cuviper, could you please try building beta with this patch applied? It should apply cleanly. If it works, I’ll nominate to land this into beta. Fixes(?) https://github.com/rust-lang/rust/issues/40251

Don't use "unadjusted" ABI on non windows platforms We introduced the unadjusted ABI to work around wrong (buggy) ABI expectations by LLVM on Windows [1]. Therefore, it should be solely used on Windows and not on other platforms, like right now is the case. [1]: see this comment for details https://github.com/rust-lang/rust/pull/38482#issuecomment-269074031

2017-02-03Bump version, upgrade bootstrapAlex Crichton-136/+57
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.

2017-01-16travis: Expand the `cross` linux imageAlex Crichton-1/+0
This expands the `cross` travis matrix entry with a few more targets that our nightlies are building: * x86_64-rumprun-netbsd * arm-unknown-linux-musleabi * arm-unknown-linux-musleabihf * armv7-unknown-linux-musleabihf * mips-unknown-linux-musl * mipsel-unknown-linux-musl This commit doesn't compile custom toolchains like our current cross-image does, but instead compiles musl manually and then compiles libunwind manually (like x86_64) for use for the ARM targets and just uses openwrt toolchains for the mips targets.

2016-12-31Auto merge of #38482 - est31:i128, r=eddybbors-1/+784
i128 and u128 support Brings i128 and u128 support to nightly rust, behind a feature flag. The goal of this PR is to do the bulk of the work for 128 bit integer support. Smaller but just as tricky features needed for stabilisation like 128 bit enum discriminants are left for future PRs. Rebased version of #37900, which in turn was a rebase + improvement of #35954 . Sadly I couldn't reopen #37900 due to github. There goes my premium position in the homu queue... [plugin-breaking-change] cc #35118 (tracking issue)
