Expand description
@brief An Upgradeable Solana BPF loader.
The upgradeable BPF loader is responsible for deploying, upgrading, and
executing BPF programs. The upgradeable loader allows a program’s authority
to update the program at any time. This ability break’s the “code is law”
contract the usually enforces the policy that once a program is on-chain it
becomes immutable. Because of this, care should be taken before executing
upgradeable programs which still have a functioning authority. For more
information refer to loader_upgradeable_instruction.rs
