Branches: main
Make `mmc --make' support submodules when compiling to Java. Java files must
be placed in subdirectories named after the package that each class belongs to.
compiler/java_names.m
compiler/parse_tree.m:
compiler/notes/compiler_design.html:
Add a new module in the parse_tree package to contain code related to
name mangling for Java.
compiler/mlds.m:
compiler/java_util.m:
Move predicates to java_names.m.
compiler/mlds_to_java.m:
Move predicates to java_names.m.
Delete an unused predicate.
compiler/file_names.m:
Rename `erlang_module_name' as it is now also used for Java.
Make `module_name_to_file_name_general' return file names for `.java'
and `.class' files that include package subdirectories.
compiler/make.program_target.m:
Clean `.class' files on make clean.
compiler/mlds_to_il.m:
mdbcomp/prim_data.m:
Move `sym_name_to_list' to mdbcomp.prim_data.
compiler/compile_target_code.m:
compiler/elds_to_erlang.m:
Conform to changes.
library/Mmakefile:
Delete hacks that work around Mercury not writing submodule .java files
in subdirectories.
