### Glossary

- Splatter: a code generator backend that concaternates configurable macros instead of doing isel
- IR: Intermediate Representation, our high-level opcode representation, loosely modeling arm64
- SSA: Single Static Assignment, a form of representing IR in memory
- Basic Block: A block of instructions with no control flow, terminated by control flow
- Fragment: A Collection of basic blocks, possibly an entire guest function or a subset of it
