Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
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.
browser/cterm.m:
browser/tree234_cc.m:
Import only one module per line.
tests/hard_coded/boyer.m:
Fix something I missed.
tests/invalid/unify_mode_error.m:
Back out my bogus change to this file.
tests/invalid/unify_mode_error.err_exp:
Update the expected output to conform to recent changes to the
behaviour of the `Please recompile with `-E' prompt'.

Branches: main, release
Do not allow discriminated unions with a single zero-arity constructor to have
user-defined equality or comparison. Defining such types causes an assertion
failure in the compiler because the types are considered to be dummy types and
the runtime currently doesn't support (and probably won't ever) d.u. dummy
types with user-defined equality or comparison.
Fix another bug where the compiler was not printing out the `recompile with
-E' prompt at the appropriate time. The bug was caused by the fact that there
were several copies of the globals structure and the one that was being
checked at the time the prompt was being printed out was not the one that had
been updated during the rest of compilation.
compiler/add_types.m:
Emit an error message if an attempt is made to define a d.u. dummy
type with user-defined equality or comparison.
compiler/globals.m:
Remove the extra_error_info field from the globals structure and turn
it into a mutable. Export access predicates for this mutable. The
reason for doing this is that the compiler was sometimes looking at
the wrong copy of the globals structure when checking the value of
this flag - this meant that sometimes the recompile with `-E' prompt
was not being displayed. Turning this flag into a mutable avoids the
problem because now there is only one copy.
compiler/make_hlds.m:
s/__/./ in a few spots.
doc/reference_manual.texi:
Mention the new restrictions on discriminated union types with
user-defined equality or comparison.
tests/invalid/exported_unify2.m:
tests/invalid/exported_unify3.m:
Change some types with user-defined equality or comparison so that
they are no longer dummy types. These test cases have not been
triggering the assertion failure in the compiler because they are only
error checked and the assertion that is failing occurs further along
in the compilation process.
tests/invalid/user_eq_dummy.{m,err_exp}:
Test the new error message for dummy types with user-defined equality
or comparison.
tests/invalid/extra_info_prompt.{m,err_exp}:
Test that the recompile with `-E' prompt is being displayed when it
should.
tests/invalid/Mercury.options:
tests/invalid/Mmakefile:
Include the new test cases.
Where there is a verbose version of the error message compile with
`-E'.
tests/recompilation/add_type_re.err_exp.2:
tests/invalid/*.err_exp:
Update expected outputs to conform to the above.
Estimated hours taken: 0.5
compiler/polymorphism.m:
Don't specialize calls to unify/2, index/2 and compare/3 into
type-specific versions here because it stuffs up the predicate
names in mode error messages. The optimization is done in
higher_order.m.
tests/invalid/Mmakefile:
tests/invalid/unify_mode_error.m:
tests/invalid/unify_mode_error.err_exp:
Test case.
