Description

We are now on a "stable" toolchain, which closed out https://github.com/oxidecomputer/hubris/issues/1927

However, we have to set RUSTC_BOOTSTRAP=1 to enable the one feature that we care about, -Zemit-stack-sizes.

We explicitly deny all nightly features with -Zallow-features= (this is the empty list), so no one can use nightly features in Rust code. Unfortunately, once you opt into Nightly Mode™, codegen changes significantly – even with all nightly features banned. This is sad, because it somewhat defeats the purpose of being on stable.

Research direction

Start by locating the repository's Rust toolchain and build configuration that sets RUSTC_BOOTSTRAP=1, enables -Zemit-stack-sizes, and denies nightly features. Investigate whether the required stack-size output can work without Nightly Mode, then verify that the configuration no longer needs the bootstrap override while preserving the existing feature restriction.
