Changes and additions to the Java back-end so that:
o While tags shouldn't be generated, they do get generated in some cases
and are now handled correctly.
o The Java back-end now generates class constructors.
o The Java back-end is now able to simulate the behaviour of function
pointers, which are used for closures, continuations, as well as unify
and compare.
mercury/compiler/mlds_to_java.m:
Extensive changes to existing code to implement tags and class
constructors. Also, addition of code to search MLDS for uses of
function pointers and to generate MLDS for wrapper classes. As well
as many small bug fixes.
Removed some (unfinished) code for dealing with Unify and Compare, this
code was redundant now that function pointers have been implemented.
mercury/compiler/java_util.m:
Updated to return noops for most tag operators.
mercury/java/MethodPtr.java:
New file. This is the interface which the wrapper classes used for
function pointers extend.
