8 : https://github.com/anza-xyz/agave/blob/v1.18.12/programs/bpf_loader/src/syscalls/mod.rs#L1895-L1959
9 : With trait impl for sha256, keccak256 and blake3:

12 : Notes:
13 : 1. Max slices, base cost and byte cost are the same for all 3 hash functions:
14 : - https://github.com/anza-xyz/agave/blob/v1.18.12/programs/bpf_loader/src/syscalls/mod.rs#L189-L197
15 : - https://github.com/anza-xyz/agave/blob/v1.18.12/programs/bpf_loader/src/syscalls/mod.rs#L216-L224
16 : 2. Poseidon doesn't follow this generic hash implementation (so we left it in fd_vm_syscall_crypto.c):
17 : - https://github.com/anza-xyz/agave/blob/v1.18.12/programs/bpf_loader/src/syscalls/mod.rs#L1678
18 :
19 : Implementation notes.
20 : Because of the notes above, we implemented fd_vm_syscall_sol_sha256() following the generic hash
21 : syscall step by step.
22 : The other implementations are just a copy & paste, replacing the hash function.
23 : Resisted the temptation to do a macro, because it would complicate future changes, for example if
24 : we were to modify CU costs. */
