Bug fixes and additions to the Java back-end so that it will now successfully
compile and run mercury programs which contain higher order code as well as
non-deterministic code.
With some hacked up Mercury library code (in Java) I am able to compile 10 of
the 11 files in the tests/benchmarks directory into Java and run them to
receive the correct output.
mercury/compiler/mlds_to_java.m:
Many small bug fixes.
Disabled current (incomplete) name mangling code. All class, package
and method names apart from java.* and mercury.runtime.* will be
output as lowercase for the moment.
Added code to prefix some classes/packages so we don't run into the
problem of having a class or package name which is also a Java reserved
word. This is the case with the mercury library modules int and char.
Added code to implement commits.
mercury/compiler/java_util.m:
Added a few missing Java reserved words.
mercury/compiler/ml_code_util.m:
A small change so that in one case where they weren't, multiple return
values are now generated in the MLDS.
mercury/java/Commit.java:
Added this file, a throwable class used for the implementation of
commits.
mercury/java/ProcAddr.java:
mercury/java/Compare.java:
mercury/java/Unify.java:
Removed these files, they're now obsolete as they all use the standard
interface for method pointers provided by MethodPtr.java.
mercury/java/TypeCtorInfo_Struct.java:
Altered to reference mercury.runtime.MethodPtr instead of
mercury.runtime.[Unify|Compare].
