php-in-php: unpack() — delete phpc_unpack.c (~577 lines), JIT/AOT from ext/standard/unpack.php #5442
Description
Category
php-in-php · stdlib
Problem
unpack() VM lives in ext/standard/unpack.php, but JIT/AOT still link lib/AOT/runtime/phpc_unpack.c (~577 lines). Delete C after LLVM lowering from PHP (pairs #5231 pack() / phpc_pack.c).

claim: PHP Runtime → PHP — starting this run (unpack: delete phpc_unpack.c, UnpackEngine + JIT lowering)
