Replace placeholder types with int64 and uint64 as appropriate throughout the
system.
Enable support for 64-bit integer literals in the compiler.
Add initial library support for 64-bit integers.
configure.ac:
Check that the bootstrap compiler recognises int64 and uint64 as
builtins.
library/int64.m:
library/uint64.m:
Populate these two modules to the extent that we can now run
basic tests of 64-bit integer support.
Note that since the bootstrap compiler will not recognise
64-bit integer literals, any such literals are current written
as conversions from ints; this will be replaced once this change
has bootstrapped.
library/private_builtin.m:
Replace the placeholder definitions for builtin unification and
comparison of 64-bit integers with their actual definitions.
library/integer.m:
Add procedures for converting integers to- and from int64 and uint64.
library/string.m:
Add functions for converting 64-bit integers into strings.
library/io.m:
Add predicates for writing 64-bit integers to text streams.
(Support for 64-bit integers with binary streams will be done
separately.)
library/stream.string_writer.m:
Add put_int64/4 and put_uint/64.
Extend the implementations of print and write to cover int64 and
uint64.
library/pprint.m:
Make int64 and uint64 instances of the doc/1 type class.
library/erlang_rtti_implementation.m:
library/rtti_implementation.m:
Handle int64 and uint64 properly in deconstruct.
library/term.m:
Add functions for converting 64-bit integers into terms.
library/term_conversion.m:
Support int64 and uint64 in univ -> term conversion.
library/Mercury.options:
Avoid a warning about the import of the require being
unused in the int64 and uint64 modules. It *is* used,
but only in the definitions used by the Erlang backend.
compiler/superhomogeneous.m:
Accept 64-bit integer literals.
compiler/c_util.m:
In C, write out the value of the min_int64 as the symbolic
constant INT64_MIN. This expands in such a way as to avoid
generating warnings from the C compiler.
compiler/builtin_ops.m:
compiler/bytecode.m:
compiler/elds.m:
compiler/elds_to_erlang.m:
compiler/hlds_data.m:
compiler/hlds_out_util.m:
compiler/llds.m:
compiler/llds_out_data.m:
compiler/lookup_switch.m:
compiler/mercury_to_mercury.m:
compiler/mlds.m:
compiler/mlds_to_cs.m:
compiler/mlds_to_java.m:
compiler/opt_debug.m:
compiler/parse_tree_out_info.m:
compiler/parse_tree_to_term.m:
compiler/prog_data.m:
compiler/prog_out.m:
compiler/prog_rep.m:
Replace the use of int as a placeholder with int64 or uint64 as
appropriate.

Add tests of basic operations on 64-bit integers.

Extend this test to cover 64-bit integers.
