JVM MODEL: M6 (Chapter 4)
-------------
See src/M6/m6-*.lisp
A good starting point is:
src/M6/m6-interpreter.lisp
State representation: (Section 4.2.1)
src/M6/m6-state.lisp
src/M6/m6-thread.lisp
src/M6/m6-class-table.lisp
...
State manipulation primitives: (Section 4.2.2)
src/M6/m6-frame-manipulation-primitives.lisp
...
State transition functions: (Section 4.2.3)
src/M6/m6-bytecode.lisp
...
Top level interpreter loop: (Section 4.3.1)
src/M6/m6-interpreter.lisp
Class initialization: (Section 4.3.2)
src/M6/m6-static-initializer.lisp
Dynamic class loading: (Section 4.3.3)
src/M6/m6-loader.lisp
src/M6-DJVM-shared/jvm-loader.lisp
RUNNING M6 AS A JVM SIMULATOR
-----------------------------
Assuming "acl2" is in your executable search path.
1. See the rough example program:
src/M6/example-*.lisp
including src/M6/example-parallel-factorial.lisp
4. To run a new Java program:
a) compile your Java program
b) convert the .class file into format M6 can use.
i) at the top level directory execute "source set-env"
ii) java jvm2acl2 output <yourclassfiles.class>
iii) edit src/M6-DJVM-shared/cldc-classtable.lisp and merge
forms from output-classtable.lisp
c) edit src/M6/example-template.lisp to set up an initial state
for executing the program
d) start ACL2 and load the edited src/M6/example-template.lisp
JVM PROPERTY VERIFICATION EXAMPLE USING M6 (Section 4.4.1)
------------------------------------------
Dynamic class loading preserves invariant on JVM state.
See src/M6-DJVM-shared/jvm-loader-property.lisp
Replay the proof:
cd src
make M6-DJVM-shared/jvm-loader-property.cert
JAVA PROGRAM VERIFICATION EXAMPLE USING M6 (Section 4.4.2)
------------------------------------------
Replay the proof:
1) ADD1 program adds one:
cd src
make M6/ADD1-program-correct.improved.cert
2) Factorial program computes factorial:
cd src
make M6/factorial-program-correct.improved.cert
CLDC BYTECODE VERIFER (Chapter 5)
