# ── Build-time CPU optimisation ────────────────────────────────────────
|
||
|
|
# Compile for the host CPU so BLAKE3 SIMD (AVX2 / AVX-512 / NEON),
|
||
|
|
# image processing and crypto routines use the fastest available
|
||
|
|
# instructions. Works on x86-64 (Intel/AMD) and ARM (Apple Silicon,
|
||
|
|
# Raspberry Pi) — the compiler auto-detects the local CPU features.
|
||
|
|
#
|
||
|
|
# NOTE: the resulting binary is NOT portable to CPUs with fewer
|
||
|
|
# features than the build host. For portable Docker images, override
|
||
|
|
# with: RUSTFLAGS="-C target-cpu=x86-64-v3" (AVX2, most servers).
