Do not run jump-threading for GPUs GPU targets have convergent operations that must not be duplicated or moved in or out of control-flow. An example convergent operation is a barrier/syncthreads. The only MIR pass affected by this is jump-threading, it can duplicate calls. Disable jump-hreading for GPU targets to prevent generating incorrect code. This affects the amdgpu and nvptx targets. Fixes rust-lang/rust#137086, see this issue for details. Tracking issue: rust-lang/rust#135024 cc @RDambrosio016 @kjetilkjeka for nvptx cc @ZuseZ4
stdarch - Rust's standard library SIMD components
This repository contains the core_arch crate, which implements core::arch - Rust's core library architecture-specific intrinsics.
The std::simd component now lives in the
packed_simd_2 crate.
Synchronizing josh subtree with rustc
This repository is linked to rust-lang/rust as a josh subtree. You can use the rustc-josh-sync tool to perform synchronization.
You can find a guide on how to perform the synchronization here.
