tests/warnings/*.m:
Bring the programming style of these modules up to date,
except where the problem being tested for seems to be related
to the old programming style
In the infinite_recursion test case, add code that we *should*
warn about, but currently don't.
tests/warnings/*.m:
Update the expected outputs to account for the changes in line
numbers, and the fact that the compiler computes the contexts
of (if C then T else E) if-then-elses differently from (C -> T; E)
if-then-else (it takes the context of the "then" vs the context
of the ";").
Delete arg_order_rearrangment.exp2. It was long unused, but
deleting it in CVS would not have allowed us to put it back later.

Make these tests use four-space indentation, and ensure that

to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the tests
that check compiler error messages, expect the new line numbers.

A big step towards cleaning up the way we handle errors. The main changes are
- the provision, in error_util.m, of a mechanism for completely specifying
everything to do with a single error in one data structure,
- the conversion of typecheck_errors.m from using io.write_string to
using this new capability,
- the conversion of mode_errors.m and det_report.m from using
write_error_pieces to using this new capability, and
- consistently using the quoting style `symname'/N instead of `symname/N'
in error_util and hlds_error_util (previously, error_util used the former
but hlds_error_util used the latter).
This diff sets up later diffs which will collect all error specifications
in a central place and print them all at once, in order.
compiler/error_util.m:
The new type error_spec, which completely specifies an error.
An error_spec may have multiple components with different contexts
and may have parts which are printed only under certain conditions,
e.g. a given option being set. Each error_spec has a severity
and also records which phase found the error.
The new predicate write_error_spec takes care of updates of the exit
status for errors and (if --halt-at-warn is set) for warnings. It also
takes care of setting the flag that calls for the reminder about -E
at the end.
This diff also makes it simpler to use the ability to print arbitrary
output. It adds the ability to include integers in messages directly,
and the ability to create blank lines. It renames some function symbols
to avoid ambiguities.
Move a predicate that only used by typecheck_errors.m to that file.
compiler/hlds_error_util.m:
Switch to the `symname'/N quoting style for describing predicates and
procedures.
compiler/prog_util.m:
Switch to the `symname'/N quoting style for describing
sym_name_and_arity.
compiler/hlds_module.m:
Provide a predicate to increment the number of errors not by one,
but by the number of errors printed by write_error_spec.
Fix some documentation rot.
compiler/typecheck_errors.m:
Use write_error_spec instead of io.write_strings to print error
messages. In several cases, improve the formatting of the messages
printed.
Mark a number of places where we don't (yet) update the number of
errors in the module_info correctly.
Rename the checkpoint predicate to avoid potential ambiguity with
similar predicates in e.g. mode_info.
compiler/typecheck_info.m:
Group the code for writing stuff out together in one bunch. For each
such predicate, create another that returns a list of format components
instead of doing I/O directly.
compiler/typecheck.m:
Move the code for writing inference messages here from
typecheck_errors.m, since these messages aren't errors.
compiler/mode_errors.m:
compiler/det_report.m:
Use write_error_spec instead of write_error_pieces. In the case of
mode_errors.m, this means we now get correct the set of circumstances
in which we set the flag that calls for the reminder about -E.
compiler/add_pragma.m:
compiler/add_type.m:
Convert some code that used to use write_error_pieces to print error
messages to use write_error_spec instead.
compiler/assertion.m:
compiler/hlds_pred.m:
compiler/post_typecheck.m:
Assertion.m used to contain some code to check for assertions in the
interface that mention predicates that are not exported. Move most
of this code to post_typecheck.m (which is where this code used to be
called from). One small part, which is a test for a particular property
of import_statuses, is moved to hlds_pred.m to be with all the other
similar tests of import_statuses.
compiler/prog_util.m:
Change unqualify_name from a predicate to a function.
compiler/pred_table.m:
compiler/hlds_out.m:
Avoid some ambiguities by adding a suffix to the names of some
predicates.
compiler/*.m:

library/list.m:
Add a function that was previously present (with different names)
in two compiler modules.
tests/hard_coded/allow_stubs.exp:
Update the format of the expected exception.
tests/invalid/errors2.err_exp2:

expected output on the main branch. (It originated on the alias branch
way back in the mists of time.)

compiler/llds_out.m:
Bring these modules up to date with our current style guidelines.
Use state variables in the few places where we weren't doing so
already.
compiler/purity.m:
Bring this module up to date with our current style guidelines.
Use the predicates of error_util and hlds_error_util to print error
messages. Be more consistent in using quotations. Fix indentation.
compiler/error_util.m:
Add a long needed facility: the ability to glue some punctuation
at the end of a previous word.
Add a mechanism for turning a list of components into a string,
instead of printing them out.
Make the interface of this module more consistent by making
list_to_pieces a function just like component_lists_to_pieces.
compiler/hlds_error_util.m:
Change the way we describe predicates and procedures. Instead of
returning their descriptions as single fixed strings that error_util
can't break up across lines, return them as separate components that
can be split across lines. This makes error output look nicer.
Fix a mismatch between what were supposed to be corresponding pieces
of code in hlds_error_util and hlds_out.
Turn the appropriate predicates into functions.

Factor out some common code.
compiler/det_report.m:
Add the new error type for predicates with I/O states.
Use error_util much more extensively to generate error messages.
compiler/hlds_out.m:
For several existing predicates that write out various HLDS
constructs, provide versions that return representations of those
constructs as strings or as error_util pieces, for use by det_report.m.
Redefine the old predicates as simply printing the output of the new
predicates where relevant, to avoid code duplication.
compiler/error_util.m:
When describing a predicate name, specify whether we want to module
qualify the name or not. The intention is that when generating a kind
of error message which can only be generated for predicates defined
in the current module, the module prefix should be omitted in the
interest of clarity.
