I'm using Ubuntu Linux 20.04.

I have a project which build some .c files (lttng tracepoints) in build.rs with cc::Build and link it to executable.
In stable version of Rust toolchain everything works fine.

But when compiling it with nightly Rust toolchain some tracepoint data is missing in resulting executable and tracing does not working.

Code

Here is the archive of minimal project which have a link problem on nightly:
lttng_link_test.zip

To build the code you may need to install liblttng-ust-dev package.
The Rust toolchain is specified in rust-toolchain.toml file of the project.

I tried this code:

> cargo build
> nm target/debug/lttng_link_test | grep tracepoint_ptr

I expected to see this happen:

0000000000057118 d __tracepoint_ptr_hello_world___my_first_tracepoint
0000000000057128 V __tracepoint_ptrs_registered

Instead, this happened:

0000000000059988 b __tracepoint_ptrs_registered

The __tracepoint_ptr_hello_world___my_first_tracepoint is missing.

Does it work on nightly with RUSTFLAGS="-Zlinker-features=-lld"?

What is the output of readelf -aW on the object file that is supposed to provide this symbol?

__tracepoint_ptr_hello_world___my_first_tracepoint is a local symbol, I think it ends up in a separate section (-ffunction-sections/-fdata-sections, at least several other symbols do) and there don't seem to be any relocation referencing it. I'm surprised the system linker doesn't omit this symbol too. Note that rustc passes --gc-sections to the linker to remove functions and statics which aren't referenced anywhere nor exported.

The __tracepoint_ptr_hello_world___my_first_tracepoint was mentioned as one of the difference between nm symbols of resulting binary when built in stable vs nightly. I'm not sure why exactly it is not working (tracing) when building on nightly. Maybe some other symbol or section is missing in resulting binary on which lltng toolkit is relied.

I don't think this should get the regression-from-stable-to-nightly label. We only enable lld on nightly, right? So it will keep working on stable and beta until we make lld the default there too.

After some research I've found an option to link successfully with nightly linker with following flags in .cargo/config.toml:

[target.'cfg(unix)']
rustflags = ["-C", "link-args=-z nostart-stop-gc"]

That way the tracing works with resulting binary and __tracepoint_ptr_hello_world___my_first_tracepoint also stay in it.

This looks like an issue in how LTTng generates its tracepoint symbols, without ever referencing them to ensure they'll be present in the final binary (not an LLD issue). They should already have issues with uses of --gc-sections if our understanding is correct.

This case is also hard to efficiently detect on our side, unlike some other lld/bfd differences. It's possible we can have a migration period where we also pass -Znostart-stop-gc but this undetected case here would not emit an FCW. It'd be unfortunate to run lld with a worse config, and do potentially costly checks ourselves, forever just to keep compatibility with bugs in bfd.

We have a several target platforms (x86_64 linux, aarch64 linux) for our lttng tracepoint library. The -Znostart-stop-gc works for x86_64 platform, but when built for aarch64 (via cross compilation) it crash in runtime when using lttng function to check if the tracepoint enabled. Probably there are more sections or symbols missing, so that it doesn't work even with -Znostart-stop-gc.

In the end we reverted transition to Rust for our lttng tracepoints and keep those in C.

Also, we tried to rewrite our babeltrace sink plugin in Rust to parse tracing, but it also have linking issues when building with cc and linking it to a Rust binary. The -Znostart-stop-gc doesn't work for it even on x86_64. For some reason the required sections exists, but empty. So, in the end the sink plugin thunk was built in C to standalone binary and we set up callbacks in runtime to it from Rust binary at plugin initialization.

With #137685, we now pass the LLD -znostart-stop-gc flag to LLD by default. Could you please check if that has resolved your original issue with (using a fresh nightly)?
