Branches: main
Make `:- initialise' and `:- finalise' declarations work in Java grades.
Initialisation predicates are simply called from static initialisation blocks.
Finalisation predicates work by registering methods (objects) with the
JavaInternal runtime class. After main/2 terminates each of the registered
methods is called.
compiler/make_hlds_passes.m:
Make add_pass_3_initialise, add_pass_3_finalise generate predicates
for backends other than C.
compiler/mlds_to_java.m:
Generate code to register finalisation predicates with the runtime.
Make the generated code that calls main/2 call run the registered
finalisers as well.
java/runtime/JavaInternal.java:
Add code to register and call finalisers when main/2 terminates.
