The default build's largest size contributor on the stack was H23's
-falign-functions=64 on every x86-64 runtime unit (2-11 KB per program;
results/h45-size-budget). Release and library flavors now keep the
compiler's default function alignment; the opt-in speed flavor keeps the
blanket 64-byte alignment. Vendored archives stay 64-byte aligned
(lre_exec keeps its pinned placement) except libunicode.c, whose small
table helpers were most of the regex programs' padding. The runtime-first
link order is unchanged.
Docs and usage text describe speed without the reverted runtime profile.
Speed is a third native optimization posture next to release (default,
-O2) and dev (-O0). It is optimized exactly like release at the C/LLVM
level and is the switch for optimizations that trade executable size and
build time for run-time speed, so the default release build stays inside
the binary-size budget.
- backend/optimization.ts: the NativeOptimization type, its -O class, and
cache-key helpers. Release keeps its historical key shapes (absent).
- CLI: build/run/cache warm accept speed; usage text names the trade.
Bootstrap's routed executable cache mirrors the posture.
- Early executable cache keys and native-feature validation include speed,
so release, dev, and speed entries never satisfy one another.
- Runtime packs: an optional executable `speed` flavor (-O2, only beside
release). Speed links it when present and the release objects otherwise;
library modes link their release flavor. The sanitizer lane follows the
same flavor key.
- Library profiles accept "speed".
- WASI release-only linker flags apply to speed too.
- bench-runtime: --baseline-optimization/--candidate-optimization and a
per-contender cold_build_ms.
Release executables are byte-identical to the stack tip for all 14
benchmark workloads (macOS arm64, sha256 of executables built from both
trees).
- Enforce oxlint and oxfmt for owned JavaScript and TypeScript with independent CI checks.
- Preserve compiler import boundaries and protected fixtures while cleaning up lint findings.
- Standardize source formatting and validate import, fixture, and embedded-source protections.
* feat: ship the self-hosted native scriptc CLI
- Run the shared compiler and CLI natively, including library builds and compile-time evaluation.
- Install native platform packages and ship relocatable standalone distributions.
- Preserve program semantics and reuse validated build artifacts for fast rebuilds.
* fix: complete native CLI integration and validation
- Preserve library diagnostics and run recursive compiler work on the main stack.
- Restore packaged helper permissions and exercise native npm and Wasm library builds.
- Recover interrupted Sandbox status probes within the original command deadline.
