llvm-bitstream
A content-agnostic parser for LLVM's bitstream container format.
Conceptually, this library is one step below a full LLVM bitcode parser: it can interpret the entries in a bitstream, but isn't aware of their semantics and isn't responsible for composing them into an LLVM IR program (or any other concrete structure that's been serialized as a bitstream).
This library uses llvm-bitcursor
under the hood.
