…nary, but without vectorization (helped by the -O2 inlining), the interpreter hot path might not stay hot in the CPU caches. if using JSC on Android, users probably have a Very Good Reason(tm), but I'm not sure which they care about more: app download size or performance per watt efficiency.

…warning (to about warnings as errors killing the build unnecessarily), but also disable loop vectorization options until NDK can be bumped. downgrade to c++20 to align with React Native constraints.
…erable on any build machine
…about LTO for the binary bits that end up in the app package itself anyway. gradefully degrade to generic LTO when clang isn't detected on the system. when clang is detected, make sure we use it for generating the ICU host-run codegen
… (pixel 2 and above) for the superior vectorization codegen that's possible
…-class GC collectible, which can cause OOM on a specific synthetic stress test on mobile/wearable devices
…le React Native's lagging toolchain from other downstream users like BabylonNative
…for that matter, use cccache so that incremental updates from upstream bun-sh/webkit don't trigger the 90+ minute (time three, for each NDK) build.
…s lost when rebasing the existing patch stack on the new JSC. efault collator lazy-property is now wrapped in #if ENABLE(INTL) so the no-intl flavor never tries to instantiate ICU
machinery it does not ship. BabylonNative needs Inspector APIs to be available, and SharedArrayBuffer is now enabled for efficient communication via N-API native modules. add a small smoketest binary for NDK 28 and NDK 29 validation in Android simulator outside of the React Native-mandated NDK 27. we now have a way to validate runtime effectiveness of all NDK variant compiles within CI.
…so maybe something else is up in the compiler environment now?
