Compiler IR (Intermediate Representation)
Document the Compiler IR JNode concept in the wiki.
Value: 4
Concept Summary
Compiler's internal representation of code with SSA form. Compiler IR provides the foundation for JNode's JIT compilation, representing bytecode in an optimized intermediate form that can be efficiently translated to native code.

Skill to Use
Use the [[update-wiki|update-wiki skill]] (load with skill({ name: "update-wiki" })) for understanding JNode internals.
Context Research
Study the compiler IR package to understand the intermediate representation. Review how bytecode is analyzed and transformed into IR, how SSA form is constructed, and what optimizations can be applied. Research the relationship between IR and the L1/L2 compilers.

# Compiler IR (Intermediate Representation)
> Compiler's internal representation of code with SSA form.
## Overview
2-3 paragraph explanation of Compiler IR, its role in the JIT pipeline, and how it enables code optimization.
## Key Components
| Class / File | Role |
|---|---|
| `core/src/core/org/jnode/vm/compiler/ir/IR.java` | IR representation |
| `core/src/core/org/jnode/vm/compiler/ir/Block.java` | IR block structure |
## How It Works
Explanation of how compiler IR works, how bytecode is translated to IR, how SSA form is constructed, and how IR enables optimization.
## Gotchas & Non-Obvious Behavior
- IR must preserve bytecode semantics
- SSA construction can be complex
- Optimization must not break correctness
