- Attribute pragmas are optional, and can include arbitrary C
expressions. You can write anything there but as of writing,
- attribute named sp_inc is supported.
+ supported attributes are:
+
+ * sp_inc: Used to dynamically calculate sp increase in
+ `insn_stack_increase`.
+
+ * handles_frame: If it is true, VM moves pc before insn body.
- Attributes can access operands, but not stack (push/pop) variables.
