# Address Lookup Table Core BPF Implementation

This PR introduces the Address Lookup Table program reimplemented to Core BPF.

All Core BPF implementation notes prefixed with:

```

[Core BPF]:

```

- `SlotHashes` sysvar replaced with `Clock`.

- `build.rs` and annotations in `lib.rs` are required for `solana-frozen-abi-macro`.

- `InstructionError::Immutable` has no `ProgramError` counterpart ([#35113](https://github.com/solana-labs/solana/pull/35113)).

- `InstructionError::IncorrectAuthority` has no `ProgramError` counterpart ([#35113](https://github.com/solana-labs/solana/pull/35113)).

- `solana-program-test` will not overwrite a built-in if the BPF program you've

  provided shares the same address as an existing built-in ([#35233](https://github.com/solana-labs/solana/pull/35233)).
