Cranelift JIT/AOT Dev

Focus: Cranelift JIT‑direct and AOT (object emit + link with libnyrt.a).

Quick AOT Smoke

• Build core (once):
  • cargo build --release --features cranelift-jit
• Lower to object + link with NyRT:
  • NYASH_DISABLE_PLUGINS=1 tools/aot_smoke_cranelift.sh apps/smokes/jit_aot_string_min.nyash app_str
• Run app:
  • ./app_str

Useful env toggles

• NYASH_JIT_DUMP=1: show JIT lowering summary
• NYASH_JIT_TRACE_LOCAL=1: trace local slot loads/stores
• NYASH_JIT_TRACE_RET=1: trace return path
• NYASH_JIT_TRACE_LEN=1: trace string/any len thunks
• NYASH_JIT_DISABLE_LEN_CONST=1: disable early const‑fold for String.length

Notes

• For AOT linking: requires libnyrt.a from crates/nyrt (built by cargo build --release).
• Use target/aot_objects/ as scratch; keep per‑experiment subfolders if needed.
