The embedded bitcode should always be prepared for LTO/ThinLTO #133250

DianQK · 2024-11-20T14:24:34Z

There are currently two methods for generating bitcode that used for LTO. One method involves using -C linker-plugin-lto to emit object files as bitcode, which is the typical setting used by cargo. The other method is through -C embed-bitcode=yes.

When using with -C embed-bitcode=yes -C lto=no, we run a complete non-LTO LLVM pipeline to obtain bitcode, then the bitcode is used for LTO. We run the Call Graph Profile Pass twice on the same module.

This PR is doing something similar to LLVM's buildFatLTODefaultPipeline, obtaining the bitcode for embedding after running buildThinLTOPreLinkDefaultPipeline.

Finished benchmarking commit (5a6a7f3): comparison URL.

Overall result: ❌✅ regressions and improvements - please read the text below

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.

This focuses on the no-lto case, but don't we currently also embed post-link bitcode when using thin-local?

I'm a bit concerned that this is implemented by running by module cloning and a separate optimization pipeline. This is slow and cloning has correctness issues (though I think they're blockaddress related, so currently not relevant for Rust). The way LLVM itself does this (see buildFatLTODefaultPipeline) is to embed the bitcode post-ThinLTOPreLink and then run ModuleOptimization (on the same module) before codegen.
