Implementation of EusLisp

• Pointer coding and object structure
• Class Inheritance Hierarchy and Type Discrimination
• Memory Management
  • Fibonacci Buddy
  • Free Lisp Management
  • Thread Local Heap Management
• Fast Type Discrimination in Type Tree
  Classes are numbered according to the segmented tree configuration. When a new class is defined, renumbering occurs and the heap is scanned to change the class-id field of all the objects. By this cos at the loading time, type discrimination of any object can be performed by a constant time, namely two comparisons of short integers, regardless to the structure or the depth of the inheritance tree.
  

• Dynamic Loading
  Compiled code or any object modules are loaded by the dynamic loading library, e.g. dl_open and dl_sym.
• Interpreter
• Compiler
  EusLisp compiles source programs into C intermediate programs, which are transferred to standard C compiler.
• Foreign Function Interface
