As proposed in: https://discourse.llvm.org/t/improving-the-reproducibility-of-linker-benchmarking/86057 This is a Nix recipe for collecting reproducers for benchmarking purposes in a reproducible way. It works by injecting a linker wrapper that embeds a reproducer tarball into a non-allocated section of every linked object, which generally causes them to be smuggled out of the build tree in a section of the final binaries. It may be used in conjunction with the script lld/utils/run_benchmark.py to measure the relative performance of linker changes or compare the performance of different linkers.
