Problem

Wrong filename for the DWARF file inside the .dSYM bundle.

Steps

  1. cargo new testing
  2. Add split-debuginfo = "packed" in cargo.toml
  3. cargo build

  4. objdump -d target/debug/testing

    target/release/testing: file format mach-o arm64
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/objdump: error: 'target/release/testing.dSYM/Contents/Resources/DWARF/testing': No such file or directory
  5. ls target/release/testing.dSYM/Contents/Resources/DWARF 
    testing-297be036e0344749

This seems to be an issue after artifact uplifting in Cargo

If I understand correctly, objdump -d binary should just work if no binary.dSYM co-exists. The dSYM bundle under target/release/testing.dSYM is a symlink to the actual dSYM at target/release/deps/testing-297be036e0344749.dSYM. And should be sufficient to use it with lldb to debug.

I am not sure if the name mismatch affects things other than objdump -d.

Rename the file or remove the bundle both works. I assume that objdump takes dSYM file for priority.
