tests/hard_coded/*.m:
Rename modules as mentioned above.
In a few cases, where the main module's name itself had a suffix,
such as "_mod_a" or "_main", remove that suffix. This entails
renaming the .exp file as well. (In some cases, this meant that
the name of a helper module was "taken over" by the main module
of the test case.)
Update all references to the moved modules.
General updates to programming style, such as
- replacing DCG notation with state var notation
- replacing (C->T;E) with (if C then T else E)
- moving pred/func declarations to just before their code
- replacing io.write/io.nl sequences with io.write_line
- replacing io.print/io.nl sequences with io.print_line
- fixing too-long lines
- fixing grammar errors in comments
tests/hard_coded/Mmakefile:
tests/hard_coded/Mercury.options:
Update all references to the moved modules.
Enable the constant_prop_int test case. The fact that it wasn't enabled
before is probably an accident. (When constant_prop_int.m was created,
the test case was added to a list in the Mmakefile, but that list
was later removed due to never being referenced.)
tests/hard_coded/constant_prop_int.{m,exp}:
Delete the calls to shift operations with negative shift amounts,
since we have added a compile-time error for these since the test
was originally created.
