Summary

  • Removes explicit GC_init() call from main() — Boehm auto-initializes on first GC_malloc
  • Programs that never allocate GC memory (like hello world) skip GC init entirely
  • ~0.35ms faster cold start (13% improvement on hello world benchmark)

Test plan

  • npm run verify:quick passes
  • Before/after startup benchmark confirms improvement

remove explicit gc_init call, let boehm lazy-init on first gc_malloc

improves cold start by ~0.35ms (13%) for hello world. boehm auto-initializes
on first GC_malloc so the explicit call was unnecessary overhead.
