From 66f9b3533189c8cb59a5b18f1baefdf407ade312 Mon Sep 17 00:00:00 2001 From: Renegade334 Date: Tue, 28 Jul 2026 13:45:30 +0100 Subject: [PATCH] fix(v8): set RUSTC_BOOTSTRAP=1 when using Cargo nightly features MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We need to enable `-Z bindeps` to read the Chromium crates tree, but this is not available on Cargo release builds by default. Setting RUSTC_BOOTSTRAP overrides this behaviour. This is technically an unstable feature, but Chromium's tooling also uses it for the same purpose, and it's extremely unlikely to be withdrawn.
