linux split-dwarf fails with `-Clinker-plugin-lto` #103932

vlovich · 2022-11-03T16:54:48Z

When I add split-debuginfo = "unpacked" to my profile.release in Cargo.toml (on Linux), my build fails with:

error: failed to build archive: No such file or directory

error: could not compile `cfg-if` due to previous error
warning: build failed, waiting for other jobs to finish...

In debug I initially had the same problem but a cargo clean fixed it without requiring me to turn off split-debuginfo. However, release continues to be failing even after cargo clean.

It's silent in my macOS in release profile, but no dSYM generated. It's OK in dev profile.

vlovich · 2022-11-03T17:21:11Z

Oh not sure if it matters, but I also have debug = true set for my release build.

davidli2010 · 2022-11-03T17:38:22Z

Thanks for your reminder. I forgot that debug is off by default in release profile.

ItsEthra · 2022-11-03T18:49:42Z

Can confirm this happens for me as well but with split-debuginfo=packed.

Can you provide some more information, such as the target you are building for (x86_64-unknown-linux-gnu?), the output of rustc --version --verbose, and anything else that might help narrow down the issue? Is your profile exactly this?

[profile.release]
split-debuginfo = "unpacked"
debug = true

filialpails · 2022-11-04T03:57:40Z

I got this same error when I tried compiling with both split debug info and linker plugin LTO.

tchollingsworth · 2022-11-04T04:48:06Z

also need LTO enabled, works fine without here

Thanks @tchollingsworth for clarifying. Yeah, I do have LTO on as well.

ehuss · 2022-11-05T20:07:10Z

cc @davidtwco or @michaelwoerister in case this didn't hit your radar.

The reproduction is:

touch foo.rs
rustc --crate-type=rlib -Csplit-debuginfo=packed -Clinker-plugin-lto foo.rs

with the error:

error: failed to build archive: No such file or directory

error: aborting due to previous error

From what I can tell, the archiver is expecting a .dwo file to exist (added around here). AFAIK, that doesn't make sense with a bitcode-only output. The decision of whether or not a dwo is expected I think is made around here. I'm guessing that decision (or perhaps something at a higher level) needs to be aware that the split-dwarf won't happen with bitcode-only output? (IOW, that case should only be true if write_output_file was called with a dwo_out value with Some?)

marmeladema · 2022-11-05T23:31:23Z

Should this issue be marked as a stable-to-stable regression?

davidtwco · 2022-11-07T15:19:16Z

Submitted #104105 to fix this.

michaelwoerister · 2022-11-07T15:58:51Z

Thanks for the ping and the great pre-investigation, @ehuss!

…elwoerister llvm: dwo only emitted when object code emitted Fixes rust-lang#103932. `CompiledModule` should not think a DWARF object was emitted when a bitcode-only compilation has happened, this can confuse archive file creation (which expects to create an archive containing non-existent dwo files). r? `@michaelwoerister`

Shnatsel · 2022-11-13T21:47:28Z

I am encountering this on cargo install without LTO. (Or at least I'm not explicitly enabling LTO, and I don't have LTO enabled in ~/.cargo/config.toml). Builds in local projects work fine, only cargo install is affected.

rustc --version --verbose

release: 1.65.0

Adding the following to ~/.cargo/config.toml triggers it:

[target.x86_64-unknown-linux-gnu]
rustflags = ["-Csplit-debuginfo=packed"]

Should I open a new issue, or do you want to track this together with the LTO case?

ehuss · 2022-11-13T22:23:14Z

@Shnatsel Can you put together a reproduction? Also, it might help to post the output of --verbose with your cargo install command (along with the exact command you are running).

I imagine simply running Ubuntu 20.04 and adding this to ~/.cargo/config.toml should do the trick:

[target.x86_64-unknown-linux-gnu]
rustflags = ["-Csplit-debuginfo=packed"]

But I'll verify it and let you know.

Shnatsel · 2022-11-13T22:47:16Z

Yes, I've verified that this is reproducible on a clean Ubuntu 20.04 installation or live CD.

Other than the commands above you need to sudo apt install curl build-essential and install Rust through rustup.rs

Shnatsel · 2022-11-13T23:01:27Z

Oh, I see that the failed run does contain the -C linker-plugin-lto flag. So it is the same issue.

I'm confused why cargo install implicitly enables it by default while other invocations don't, but that's a separate issue.

ehuss · 2022-11-14T00:07:47Z

rustfilt sets LTO here. I don't know what other commands you are running, but if it is cargo build, then that would use the dev profile without LTO.
