+# Ir Matching
+
+Use tree with sub trees to match Ir operations to JIT functions
+
+1. Match Name
+2. Match Args until None or End
+3. Run JIT Fn
+
+## Object Definitions
+
+```c
+typedef struct _kpl_ir_match {
+    int32_t tree_weight;
+    union {
+        kpl_ir_name ir_name;
+        kpl_type_header type_header;
+    } match;
+    union {
+        struct _kpl_ir_match *children;
+        void *jit_fn; // TODO
+    } next;
+    struct _kpl_ir_match *tree_left *tree_right;
+} kpl_ir_match;
+```
