tests/hard_coded/*.m:
Update programming style, unless doing so would change
the meaning of the test, in particular:
- use '.' as a module qualifier in place of '__'
- use {write,print}_line where appropriate
- use if-then-else in place of C -> T ; E
- use state variables in place of DCGs
tests/hard_coded/dir_test.m:
Document what the expected outputs correspond to.
Use a uniform module qualifier in the output.
tests/hard_coded/dir_test.exp*:
Conform to the above change.

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 debugger tests,
specify the new line numbers in .inp files and expect them in .exp files.
Estimated hours taken: 0.5
library/int.m:
Fix a bug in the definition of `div'.
tests/hard_coded/division_test.m:
Add some new regression tests for the above-mentioned bug.
Estimated hours taken: 1
tests/hard_coded/division_test.m:
Fix some bugs in the test case:
div_test/4 was testing `//' rather than `div',
and the formulas used in mod_test/4 were wrong.
library/int.m:
Add a new function `div'. The idea is that `div' is the same
as `//', except that `div' will round toward minus infinity, whereas
`//' will round toward zero. `div' is more well-behaved, `//'
is more efficient.
Change the behaviour of `mod' so that it is remainder after `div'
rather than remainder after `//'. This makes it more well-behaved,
but less efficient.
Add a new function `rem', which is the new name for what `mod'
used to do (i.e. remainder after `//').
compiler/llds.m:
Add some comments about the `/' and `mod' llds operators.
(The `mod' llds operator should probably be renamed `rem',
but I haven't done that yet.)
compiler/code_util.m:
Recognize `int:rem', rather than `int:mod', as the llds `mod'
operator.
tests/hard_coded/division_test.m:
Add some test cases for `div', `mod', `//', and `rem' on
negative numbers.
