Unable to build rustc_codegen_spirv with nightly 2023-09-30

Expected Behaviour

I expected it to build without issue on 2023-09-30

Example & Steps To Reproduce

rustc_codegen_spirv fails to build because I'm using nightly 2023-09-30 instead of 2023-05-27.
Reviewing the commit history I think I'm using correct nightly version.

  1. Clone this repo: https://codeberg.org/tmvkrpxl0/voxelray
  2. run cargo build
  3. it fails

System Info

  • Rust: rustc 1.74.0-nightly (8ce4540bd 2023-09-29) (I don't know why it says 09-29 but commit hash is indeed correct)
  • OS: KDE Neon 5.27
  • GPU: Radeon 4500U
  • SPIR-V: SPIRV-Tools v2022.2-dev unknown hash, 2022-02-16T16:37:15

Backtrace

  Make sure your `rust-toolchain.toml` file contains the following:
  -------------
  [toolchain]
  channel = "nightly-2023-05-27"
  components = ["rust-src", "rustc-dev", "llvm-tools-preview"]

FWIW following your steps rust-gpu seems to work but I get the following error:

error: `#[panic_handler]` function required, but not found

error: language item required, but not found: `eh_personality`
  |
  = note: this can occur when a binary crate with `#![no_std]` is compiled for a target where `eh_personality` is defined in the standard library
  = help: you may be able to compile for a target that doesn't need `eh_personality`, specify a target with `--target` or in `.cargo/config`

error: could not compile `shader` (lib) due to 2 previous errors

You also might want to check out #1109 if you want a newer nightly.

Turns out the doc was outdated and People in discord helped me out.
