BUG: failed to parse LLVM IR

[forty]

Hello,

Error

I get the following message on my project

error: failed to parse application's LLVM IR from `project/target/x86_64-unknown-linux-gnu/release/deps/bin-0d269819aa1d3063.ll`: BUG: failed to parse LLVM IR; please submit a cargo-call-stack bug report and attach the `.ll` file: Failure("Eof in line 880")

Info

$ cargo +nightly call-stack  --version
cargo-call-stack 0.1.7
$ cargo --version
cargo 1.61.0 (a028ae4 2022-04-29)
$ rustc --version
rustc 1.61.0 (fe5b13d68 2022-05-18)

bin-0d269819aa1d3063.ll.txt

Let me know if I can help figuring it out.

thanks!

with PR #59 the llvm-ir parser can handle the .ll file you shared in the issue description

release v0.1.8 includes the fix for this issue

Wow thanks for the super fast reply! I don't have this error anymore, but now it fails on a different problem

thread 'main' panicked at 'BUG: unhandled llvm intrinsic: llvm.experimental.noalias.scope.decl', /home/forty/.cargo/registry/src/garden.eu.org-1ecc6299db9ec823/cargo-call-stack-0.1.8/src/main.rs:701:21

This llvm.experimental.noalias.scope.decl seem to indeed be present in the file I shared (but if it's supposed to work, maybe I'm doing something wrong?)

Thanks!

I only ran your file through the llvm-ir parser; I couldn't test the whole cargo-call-stack itself because I didn't have the source code of your Cargo project. I can repro the issue with a "hello, world" project; will have a look.

PR #60 should handle enough llvm instrinsics to produce a call graph for the "hello, world" program. if you are producing dynamically linked binaries check out #61
