Add an optional argument to the `specified' attribute of `pragma memo' that
allows the user to choose to table arguments introduced by the polymorphism
transformation by address instead of by value. e.g.
:- pragma memo(p/2, [specified([addr, output], hidden_arg_addr)]).
Also accept `hidden_arg_value'.
compiler/prog_io_pragma.m:
Accept the optional argument when parsing `pragma memo'.
Add some missing spaces in long error messages.
compiler/prog_data.m:
Hold the tabling method for hidden arguments when the `specified'
attribute is used.
compiler/table_gen.m:
Respect the hidden argument tabling method.
Allow typeclass_infos and base_typeclass_infos to be tabled by address
instead of aborting. The compiler still aborts if asked to table them
by value, as it's not yet implemented.
compiler/add_pragma.m:
compiler/hlds_out.m:
compiler/mercury_to_mercury.m:
Conform to the changes above.
doc/reference_manual.texi:
Add (currently commented out) documentation for the `hidden_arg_value'
and `hidden_arg_addr' options.
tests/tabling/Mmakefile:
tests/tabling/specified_hidden_arg.exp:
tests/tabling/specified_hidden_arg.m:
tests/invalid/specified.err_exp:
tests/invalid/specified.m:
Add test cases.
