This change allows parallelism of test runs to be specified by a command line flag names --test-threads in addition to the existing environment variable RUST_TEST_THREADS. Fixes rust-lang#25636.
…e more efficient tokenstream usages.
The previous implementation of this function was overly conservative with liberal usage of `Option` and `.unwrap()` which in theory never triggers. This commit essentially removes the `Option`s in favor of unsafe implementations, improving the code generation of the fast path for LLVM to see through what's happening more clearly. cc rust-lang#34727
Similar to the `as_slice` method on `core::slice::Iter` struct.
…akis [MIR] Add explicit SetDiscriminant StatementKind for deaggregating enums cc rust-lang#35186 To deaggregate enums, we need to be able to explicitly set the discriminant. This PR implements a new StatementKind that does that. I think some of the places that have `panics!` now could maybe do something smarter.
Implement From for Cell, RefCell and UnsafeCell Considering that `From` is implemented for `Box`, `Rc` and `Arc`, it seems [reasonable](https://internals.rust-lang.org/t/implementing-from-t-for-other-std-types/3744) to implement it for `Cell`, `RefCell` and `UnsafeCell`.
…=alexcrichton Add --test-threads option to test binaries This change allows parallelism of test runs to be specified by a command line flag names --test-threads in addition to the existing environment variable RUST_TEST_THREADS. Fixes rust-lang#25636.

…alexcrichton Introduce `as_slice`/`as_mut_slice` methods on `std::vec::IntoIter` struct. Similar to the `as_slice` method on `core::slice::Iter` struct.
…matsakis Correct span for pub_restricted field Fix rust-lang#35435.
Add regression test for rust-lang#22894. None
Kicking off libproc_macro This PR introduces `libproc_macro`, which is currently quite bare-bones (just a few macro construction tools and an initial `quote!` macro). This PR also introduces a few test cases for it, and an additional `shim` file (at `src/libsyntax/ext/proc_macro_shim.rs` to allow a facsimile usage of Macros 2.0 *today*!
Implemented a smarter TokenStream concatenation system The new algorithm performs 'aggressive compacting' during concatenation as follows: - If the nodes' combined total total length is less than 32, we copy both of them into a new vector and build a new leaf node. - If one node is an internal node and the other is a 'small' leaf (length<32), we recur down the internal node on the appropriate side. - Otherwise, we construct a new internal node that points to them as left and right. This should produce notably better behavior than the current concatenation implementation.
