Mark the X_to_doc function in each of these modules as obsolete,
and make it a forwarding function to the actual implementation
in pretty_printer.m. The intention is that when these forwarding
functions are eventually removed, this will also remove the dependency
of these modules on pretty_printer.m. This should help at least some
of these modules escape the giant SCC in the library's dependency graph.
(It does not make sense that a library module that adds code to increment
an int thereby becomes dependent on pretty_printer.m through int.m.)
library/pretty_printer.m:
Move all the X_to_doc functions from the above modules here.
Fix the one_or_more_to_doc function, which was
- missing the comma between the two arguments of the one_or_more
function symbol, and
- would print "..., ...]" instead of just "...]" at the end of the
tail list when that list exceeded the limits of the specified pp_params.
Rename one of the moved types along with its function symbols,
to reduce ambiguity.
Put arrays before their indexes in the argument lists of some of
the moved functions.
Some of the moved X_to_doc functions for compound types returned
a doc that had an indent wrapper. These indents differed between the
various X_to_doc functions without any visible reason, but they are
also redundant. The callers can trivially add such wrappers if they
want to, but taking them off, if they want them off, is harder.
Eliminate the problem by deleting all such indent wrappers.
Add formatters for the intN, uintN and one_or_more types to the
default formatter map. Their previous absence was an oversight.
Add a function, get_formatter_map_entry_types, that returns the ids
of the types in the formatter_map given to the function. It is intended
for tests/hard_coded/test_pretty_printer_defaults.m, but is exported
for anyone to use.
tests/hard_coded/test_pretty_printer_defaults.{m,exp}:
Use get_formatter_map_entry_types to print the default formatter map
in a format that is much more easily readable.

As above. This mostly involved two things.
The first was grouping foreign_procs by predicate instead of by language.
In a few cases, this revealed that some predicates *had* no foreign_proc
for a language, while related predicates did have one that just aborted
if called. This diff adds similar aborting foreign_procs to predicate/
language combinations that were missing them, when this seemed obviously
the right thing to do.
The second was moving pragmas about a predicate from the middle of the
block of clauses of that predicate to the start of that block.
Discussion of these changes can be found on the Mercury developers
mailing list archives from June 2018.
COPYING.LIB:

compiler/hlds_data.m:
Add bespoke types to record information about local and remote secondary
tags. The one for local secondary tags includes the value of the
primary and secondary tag together, since construct unifications
need to assign this value, and it is better to compute this once,
instead leaving the target language compiler to do it, potentially
many times.
Use a wrapped uint8 to record primary tag values, and wrapped uints
to record secondary tag values. The wrap is to prevent any accidental
confusion with other values. The use of uint8 and uint has two purposes.
First, using the tighest possible representation. Tags are never negative,
and primary tags cannot exceed 7. Second, using these types in the compiler
help us eat our own dogfood; if a change causes a problem affecting
these types, its bootcheck should fail, alerting us to the problem.
Add commented-out types and fields that will be needed for packing
sub-word-sized arguments together with both local and remote secondary
tags.
compiler/du_type_layout.m:
Generate references to tags in the new format.
compiler/ml_unify_gen.m:

Cast the argument of write_binary_int8 to a uint8 before writing

tests/invalid/invalid_int.err_exp2:
Extend this test case to cover the fixed size integer types.
Add the new builtin types: int8, uint8, int16, uint16, int32 and uint32.
Support for these new types will need to be bootstrapped over several changes.
This is the first such change and does the following:
- Extends the compiler to recognise 'int8', 'uint8', 'int16', 'uint16', 'int32'
and 'uint32' as builtin types.
- Extends the set of builtin arithmetic, bitwise and relational operators to
cover the new types.
- Extends all of the code generators to handle new types. There currently lots
of limitations and placeholders marked by 'XXX FIXED SIZE INT'. These will
be lifted in later changes.
- Extends the runtimes to support the new types.
- Adds new modules to the standard library intended to hold the basic
operations on the new types. (These are currently empty and not documented.)
This change does not introduce the two 64-bit types, 'int64' and 'uint64'.
Their implementation is more complicated and is best left to a separate change.
compiler/prog_type.m:
compiler/prog_data.m:
compiler/builtin_lib_types.m:
