From b3fb67e050e763ff80b90121f2b60f10d86204f5 Mon Sep 17 00:00:00 2001 From: onur-ozkan Date: Tue, 25 Jun 2024 11:36:50 +0300 Subject: [PATCH] set `on-broken-pipe` in `prepare_cargo_tool` Currently rustdoc breaks the build cache (due to having different rustflags) when building rustdoc before building another tool (e.g., `x test miri && x test rustdoc && x test miri`). This change fixes that by moving `on-broken-pipe` into `prepare_cargo_tool` so it is set for all tools.
