Research direction
The issue concerns loop unrolling in the Rust compiler's libgccjit codegen and mentions the -funroll-all-loops option. Start by reproducing the behavior and checking how loop-unrolling options are passed to libgccjit. Done means determining whether manual enabling is required and documenting or implementing the necessary behavior.
