.clif Test Case

No standalone .clif reproducer yet; this was observed in a real-world crate (sqlx with the tls-rustls-aws-lc-rs feature). I can try to reduce further with clif-util bugpoint if desired, but the Cargo project below reliably reproduces the issue.

Steps to Reproduce

• cargo new --bin repro-sqlx

• Replace Cargo.toml with:
  ```toml
  [package]
  name = "repro-sqlx"
  version = "0.1.0"
  edition = "2024"

  [dependencies]
  tokio = { version = "1.44", features = ["rt-multi-thread", "macros"] }
  sqlx = { version = "0.8.6", features = ["runtime-tokio", "tls-rustls-aws-lc-rs", "postgres", "macros"] }
  ```

• Replace src/main.rs with:
  ```rust
  use sqlx::Type;

  #[derive(Type, Debug)]
  #[sqlx(type_name = "INT4")]
  struct Dummy(i32);

  fn main() {
  println!("{:?}", Dummy(42));
  }
  ```

• Run cargo build (succeeds)

• cargo clean
• Run RUSTFLAGS='-Zcodegen-backend=cranelift' cargo build

Expected Results

The build succeeds just like it does with the default LLVM backend.

Actual Results

The sqlx_macros proc-macro dylib fails to load because the relocation keeps the \u0001 prefix from the #[link_name] attribute:

error: .../target/debug/deps/libsqlx_macros-*.so: undefined symbol: ␁aws_lc_0_32_2_CRYPTO_memcmp
  --> sqlx-0.8.6/src/lib.rs:72:1
   |
72 | pub extern crate sqlx_macros;
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Comparing the linked artifacts:

# LLVM backend
cargo clean
cargo build --offline
nm target/debug/deps/libsqlx_macros-*.so | cat -v | grep CRYPTO_memcmp
# -> 00000000008ea27e t aws_lc_0_32_2_CRYPTO_memcmp

# Cranelift backend
cargo clean
RUSTFLAGS='-Zcodegen-backend=cranelift' cargo build --offline
nm target/debug/deps/libsqlx_macros-*.so | cat -v | grep CRYPTO_memcmp
# ->                  U ^Aaws_lc_0_32_2_CRYPTO_memcmp   (^A = \u0001)

The static archive from aws-lc only defines aws_lc_0_32_2_CRYPTO_memcmp, so the loader cannot resolve \u0001aws_lc_0_32_2_CRYPTO_memcmp.

Thanks for filing an issue!

I think you will probably want to file this instead on the rust-lang/rustc_codegen_cranelift repository. To expand a bit: Cranelift proper, as hosted in this repository (e.g. the cranelift-codegen crate and a few auxiliary ones), is a core compiler backend, but is more a set of building blocks to put together a conventional compiler. The core crate doesn't even have a concept of symbols, only integer function indices (ish). rustc_codegen_cranelift, or cg_clif for short, embeds Cranelift as a library and builds a full rustc backend on top of it. The first place for triage on issues with "the Cranelift backend [for rustc]" should be that repo, and if they determine that the bug is in an underlying Cranelift component, they can redirect here again. @bjorn3 is the lead developer and maintainer of that project and might be able to help more.

I'll go ahead and close this here for now but best of luck!
