Module solana_program::bpf_loader
source · Expand description
The latest BPF loader native program.
The BPF loader is responsible for loading, finalizing, and executing BPF programs. Not all networks may support the latest loader. You can use the command-line tools to check if this version of the loader is supported by requesting the account info for the public key below.
The program format may change between loaders, and it is crucial to build
your program against the proper entrypoint semantics. All programs being
deployed to this BPF loader must build against the latest entrypoint version
located in entrypoint.rs.
Note: Programs built for older loaders must use a matching entrypoint
version. An example is bpf_loader_deprecated which requires
entrypoint_deprecated.
The solana program deploy CLI command uses the
upgradeable BPF loader.
