# `target-cpu` is intentionally left at cargo's default of `generic` here.
# Two reasons: (a) this is a virtual workspace manifest and cargo does not
# accept conditional `[target.*]` tables in virtual manifests; (b) macOS
# Apple Silicon and Linux aarch64 builds cannot both target `x86-64-v3`.
# Maintainers who want a per-microarch build drop a `.cargo/config.toml`
# next to this file with:
#     [target.x86_64-unknown-linux-gnu]
#     runner = "/…/sccache …"
#     rustflags = ["-C", "target-cpu=x86-64-v3"]
# or set `CARGO_BUILD_RUSTFLAGS=-C\ target-cpu=x86-64-v3 cargo build --release`.
