Module solana_program::bpf_loader_upgradeable

@brief An Upgradeable Safecoin 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
