Hm, okay, then since PR is a couple weeks old now, let me bump the threshold this time to satisfy the CI 🙏 . Let's discuss whether we want to remove the redundancy build check on a follow-up. |

Um, what about gentle deprecation?
Maybe an alias to the new crate?

Actually, it seems difficult to import the new crate in solana-program due to circular dependency. It seems best to just leave the original logic in solana-program and add deprecation warnings pointing to the new crate. Wdyt?

When #1827 lands, the circular dependency can be avoided by just moving the required syscall definitions from solana-program to solana-bn254

Problem
The bn128 logic in
solana-programis quite independent of the rest of the crate. Currently, the downstream projects that depend on onlysolana-program, but not bn128, will need to build with unnecessary bn128 logic, which is quite heavy.Summary of Changes
Move bn128 logic into its separate crate.
Note: I named the crate to be solana-bn254. Bn254 is a more modern and descriptive name for bn128, which does not provide 128 bits of security any more. I will limit this PR to just the restructuring of the crate; I will update the contents inside the crate to use bn254 in a follow-up PR.
This is part of #983.
