From 73e534b0220604cf79e2193d4f5960d2dda0a3b6 Mon Sep 17 00:00:00 2001 From: Jieyou Xu Date: Fri, 25 Jul 2025 19:47:54 +0800 Subject: [PATCH 1/2] Revert "Move `shared_helpers` test to a dedicated module" I missed this during review. We cannot declare a `tests` module within `shared_helpers.rs` itself, as shim binaries that tries to include the `shared_helpers` module through `#[path = ".."]` attributes would fail to find it, breaking `./x check bootstrap`.
