2019-12-02Rollup merge of #66834 - infinity0:master, r=Mark-SimulacrumRalf Jung-6/+8
rustbuild fixes When upgrading Debian's rustc to 1.38 I needed these patches: (1) In order to cross-compile rustc 1.38 and take it through the full rustbuild process including install, I needed the first patch. (2) In order to build rustc 1.38 using rustc 1.38 itself I need to set --cap-lints warn, otherwise I get this error: ~~~~ error: unnecessary `unsafe` block --> src/bootstrap/builder.rs:148:19 | 148 | name: unsafe { ::std::intrinsics::type_name::<S>() }, | ^^^^^^ unnecessary `unsafe` block | note: lint level defined here --> src/bootstrap/lib.rs:107:9 | 107 | #![deny(warnings, rust_2018_idioms, unused_lifetimes)] | ^^^^^^^^ = note: `#[deny(unused_unsafe)]` implied by `#[deny(warnings)]` error: aborting due to previous error error: could not compile `bootstrap`. ~~~~ In order to set --cap-lints warn however, I need bootstrap.py not to clobber RUSTFLAGS. (This worked previously, not sure if it was broken intentionally but we would like support for it.)
2019-12-02Rollup merge of #66827 - RalfJung:miri-missing-ret-place, r=oli-obkRalf Jung-15/+23
handle diverging functions forwarding their return place Fixes https://github.com/rust-lang/miri/issues/1075: the shim around diverging closures turned into function pointers actually "obtains" a return place inside a diverging function, but just uses it as the return place for a diverging callee. Handle this by using NULL places. This is kind of a hack as it breaks our invariant that all places are dereferencable, but we'd eventually let raw pointers break that anyway I assume so that seems fine. r? @oli-obk
2019-12-02Rollup merge of #66822 - RalfJung:miri-panic, r=oli-obkRalf Jung-59/+18
libunwind_panic: adjust miri panic hack We adjust the Miri hack in libpanic_unwind such that even with `cfg(miri)`, we build a version of libpanic_unwind that actually works. This is needed to resolve https://github.com/integer32llc/rust-playground/issues/548. r? @oli-obk @alexcrichton
2019-12-02Rollup merge of #66654 - ecstatic-morse:check-consts-ref, r=eddyb,matthewjasperRalf Jung-181/+145
Handle const-checks for `&mut` outside of `HasMutInterior` Addresses [this comment](https://github.com/rust-lang/rust/pull/64470#discussion_r328200508). Const-checking relied on `HasMutInterior` to forbid `&mut` in a const context. This was strange because all we needed to do was look for an `Rvalue::Ref` with a certain `BorrowKind`, whereas the `Qualif` traits are specifically meant to get the qualifs for a *value*. This PR removes that logic from `HasMutInterior` and moves it into `check_consts::Validator`. As a result, we can now properly handle qualifications for `static`s, which had to be ignored previously since you can e.g. borrow a static `Cell` from another `static`. We also remove the `derived_from_illegal_borrow` logic, since it is no longer necessary; we give good errors for subsequent reborrows/borrows of illegal borrows.
2019-12-02Rollup merge of #66245 - tmiasko:cfg-sanitize, r=oli-obkRalf Jung-0/+98
Conditional compilation for sanitizers Configure sanitize option when compiling with a sanitizer to make it possible to execute different code depending on whether given sanitizer is enabled or not.
2019-12-02Rollup merge of #66926 - RalfJung:miri-stop, r=oli-obkMazdak Farrokhzad-17/+13
add reusable MachineStop variant to Miri engine error enum Replace the Miri-tool-specific `Exit` error variant with something dynamically typed that all clients of the Miri engine can use. r? @oli-obk Cc https://github.com/rust-lang/rust/issues/66902
2019-12-02Rollup merge of #66918 - makotokato:aarch32-crc-crypto, r=petrochenkovMazdak Farrokhzad-0/+2
Add crc and crypto to target feature whitelist on arm aarch32 (ARMv8 32-bit) supports crc and crypto.
