library/string.m:
Add {i,u}{8.16,32,64} as function symbols in the poly_type type,
each with a single argument containing an integer with the named
signedness and size.
The idea is that each of these poly_type values works exactly
the same way as the i(_) poly_type (if signed) or the u(_) poly_type
(if unsigned), with the exception that the value specified by the call
is cast to int or uint before being processed.
library/string.parse_runtime.m:
Parse the new kinds of poly_types. Change the representation of the result
of the parsing to allow recording of the sizes of ints and uints.
Put the code that does the parsing into a predicate of its own.
library/string.format.m:
Do a cast to int or uint if the size information recorded in the
specification of a signed or unsigned integer value calls for it.
Provide functions to do the casting that do not require the import
of {int,uint}{8,16,32,64}.m. This is to allow the compiler to generate
calls to do such casts without having to implicitly import those modules.
Abort if a 64 bit number is being cast to a 32 bit word.
compiler/parse_string_format.m:
Make the same changes as in string.parse_runtime.m, mutatis mutandis.
compiler/format_call.m:
Handle the new kinds of poly_types by adding a cast to int or uint
if necessary, using the predicates added to library/string.format.m.
Use a convenience function to make code creating instmap deltas
more readable.
library/io.m:
library/pprint.m:
library/string.parse_util.m:
tests/invalid/string_format_bad.m:
tests/invalid/string_format_unknown.m:
Conform to the changes above.
tests/string_format/string_format_d.m:
tests/string_format/string_format_u.m:
Test the printing of some of the new poly_types.
tests/string_format/string_format_d.exp2:
tests/string_format/string_format_u.exp2:
Update the expected output of these tests on 64-bit platforms.
tests/string_format/string_format_lib.m:
Update programming style.
