Provide a more uniform interface to the test directories. Before this
change, the tests directory as well as direct descendents had `runtests'
scripts to execute the tests. These would run `mmake', which in turn
would recursively run `mmake' in any subdirectories. The subdirectories
did not have their own `runtests' scripts.
This change adds a `runtests' script to those subdirectories that did
not have them before. The scripts have the same meaning as they did
previously---run all tests in the current directory and below, and
return a status of 0 only if all tests pass.
The rationale for this change is so that each directory in the tests
is treated the same, regardless of whether it is a top-level
directory or not. This means, for example, that any test directory can
be used as an argument to the `--test-dir' option to tools/bootcheck.
This change also links tests/general/accumulator into the automated
testing suite.

Fix a subtle bug in the new way of handling failure. When we enter the
last disjunct of a model_non disjunction inside the model_non condition
of an if-then-else, set resume_point_known to unknown. This forces code
in the last disjunct and after the last disjunction to fail by invoking
redo(), not by a direct branch. The reason this is necessary that a direct
branch to the start of the else case is incorrect if the condition has
already returned some answers.
The bug was causing tests/general/complex_failure to fail at optimization
levels that caused the inlining of a predicate, which resulted in a disjunction
inside the last disjunct of a disjunction inside a model_non condition.
compiler/notes/failure.html:
Modify the description of failure handling to encompass the solution
of the problem.
compiler/code_info.m:
Implement the solution.
tests/general/semi_fail_in_non_ite.{m,exp}:
Add a new test case, a variant of complex_failure, that tests for the
bug at all optimization levels.
tests/general/Mmakefile:
Enable the new test case.

Extend the new failure handling method to optionally preserve an invariant
required by accurate gc: always being able to tell with respect to what MR_sp
or MR_curfr to interpret the stackvars and framevars referred to by the label
whose address is the redoip slot of a nondet stack frame. This basically
requires limitations on the hijacking of redoip/redofr slot pairs.
compiler/notes/failure.html:
Describe the new extension.
Change the terminology to conform to what is used in the code.
compiler/llds.m:
For each temporary frame on the nondet stack, specify the native
stack of the procedure that created it. This is so that we know
whether the temporary frame ought to have the fourth slot that
specifies the right value of MR_sp. (The fourth slot is included
only in temporary nondet stack frames created procedures that live
on the det stack; procedures that live on the nondet stack never
have any of their variables on the det stack.)
Remove the modframe llds instruction, since it does not specify
what frame's redoip slot it is assigning to. This is error-prone
(see peephole.m below). We were not using modframe much anyway.
compiler/llds_out.m:
compiler/opt_debug.m:
Emit either mktempframe or mkdettempframe depending on the new
field in temp_frame.
compiler/code_info.m:
Add a fourth item to the failure state, which states whether
the top frame of the nondet stack may be hijacked. Initialize
it from the option --allow-hijacks. If about to do a hijack
but the failure state says no, create a temporary frame instead.
Separate out the code for creating temporary frames, since it
is now called from more than one place. Generalize the code
to handle the new type of temp frame.
compiler/code_info.m:
compiler/ite_gen.m:
Simplify the way we transmit information about the location
of the address of the nondet stack frame in which the soft cut
is performed from the start of the condition to its end.
Remove the predicate code_info__maybe_push_temp_frame;
its functionality is now achieved in code_info.m by disabling
and restoring --allow-hijacks around the generation of code
for the condition. This also allows us to get rid of the code
that finds out whether the condition can do any hijacking.
compiler/opt_util.m:
Rename next_modframe as next_assign_to_redoip, and add an additional
argument that says which frame's redoip we are after.
compiler/peephole.m:
Use the new argument of opt_util__next_assign_to_redoip to fix a bug
where a mkframe of a temporary frame (which leaves curfr unchanged)
that was followed a modframe (which assigns to the redoip of curfr)
was incorrectly optimized (the assignment to the redoip slot was
applied to the temporary frame, not the ordinary one).
compiler/*.m:
Minor changes to accommodate the disappearance of modframe.
runtime/mercury_stacks.h:
Add macros to support four-word temp frames on the nondet stack.
Make the macros that access nondet stack frame slots start with MR_,
while keeping (redefined) macros needed for backward compatibility.
Remove the modframe macro.
Fix a dangling reference to PREDNM instead of MR_PREDNM.
runtime/mercury_stack_trace.c:
Modify the stack tracing code to allow for the new four-word temp
frames.
Use the new MR_ prefixed variants of the macros.

tests/{general,hard_coded}/space.{m,exp}:
Move this test case from general to hard_coded. Although NU-Prolog
can execute it, it does not give the same answers as Mercury due to
a different default ordering and a difference in integer size (26-bit
integers in NU-Prolog) that changes the behavior of the pseudo
random-number generator.

Allow modules to be put in source files whose names do not directly match
their the module names. When looking for the source for a module such
as `foo:bar:baz', search for it first in `foo.bar.baz.m', then in `bar.baz.m',
and finally in `baz.m'.
compiler/prog_io.m:
Change prog_io__read_module so that it returns the name of
the module read, as determined by the `:- module' declaration.
Add predicate `check_module_has_expected_name', for checking
that this name matches what was expected.
compiler/modules.m:
Add read_mod_from_file, for reading a module given the file name,
and generated_file_dependencies, for generating the dependencies
of a module given the file name. (As opposed to the module name.)
Change read_mod and read_mod_ignore_errors so that they
search for `.m' files as described above, and return the name
of the source file read.
Also improve the efficiency of read_dependencies slightly:
when reading in `.int' files, there's no need to call
split_into_submodules, because we generate a seperate
`.int' file for each submodule anyway.
compiler/mercury_compile.m:
Change the handling of command-line arguments.
Arguments ending with `.m' are assumed to be file names,
and other arguments are assumed to be module names.
For file names, call read_mod_from_file instead of read_mod.

Add support for nested modules.
- module names may themselves be module-qualified
- modules may contain `:- include_module' declarations
which name sub-modules
- a sub-module has access to all the declarations in the
parent module (including its implementation section).
This support is not yet complete; see the BUGS and LIMITATIONS below.
LIMITATIONS
- source file names must match module names
(just as they did previously)
- mmc doesn't allow path names on the command line any more
(e.g. `mmc --make-int ../library/foo.m').
- import_module declarations must use the fully-qualified module name
- module qualifiers must use the fully-qualified module name
- no support for root-qualified module names
(e.g. `:parent:child' instead of `parent:child').
- modules may not be physically nested (only logical nesting, via
`include_module').
BUGS
- doesn't check that the parent module is imported/used before allowing
import/use of its sub-modules.
- doesn't check that there is an include_module declaration in the
parent for each module claiming to be a child of that parent
- privacy of private modules is not enforced

compiler/prog_data.m:
Add new `include_module' declaration.
Change the `module_name' and `module_specifier' types
from strings to sym_names, so that module names can
themselves be module qualified.
compiler/modules.m:
Add predicates module_name_to_file_name/2 and
file_name_to_module_name/2.
Lots of changes to handle parent module dependencies,
to create parent interface (`.int0') files, to read them in,
to output correct dependencies information for them to the
`.d' and `.dep' files, etc.
Rewrite a lot of the code to improve the readability
(add comments, use subroutines, better variable names).
Also fix a couple of bugs:
- generate_dependencies was using the transitive implementation
dependencies rather than the transitive interface dependencies
to compute the `.int3' dependencies when writing `.d' files
(this bug was introduced during crs's changes to support
`.trans_opt' files)
- when creating the `.int' file, it was reading in the
interfaces for modules imported in the implementation section,
not just those in the interface section.
This meant that the compiler missed a lot of errors.

Change code that prints out module names or converts

module names are now sym_names intead of strings.
Also change a few places (e.g. in intermod.m, hlds_module.m)
where the code assumed that any qualified symbol was
fully-qualified.
compiler/prog_io.m:
compiler/prog_io_goal.m:
Move sym_name_and_args/3, parse_qualified_term/4 and
parse_qualified_term/5 preds from prog_io_goal.m to prog_io.m,
since they are very similar to the parse_symbol_name/2 predicate
already in prog_io.m. Rewrite these predicates, both
to improve maintainability, and to handle the newly
allowed syntax (module-qualified module names).
Rename parse_qualified_term/5 as `parse_implicit_qualified_term'.

compiler/polymorphism.m:
Ensure that the type names `type_info' and `typeclass_info' are
module-qualified in the generated code. This avoids a problem
where the code generated by polymorphism.m was not considered

tests/hard_coded/agg.m to fail.
Make sure types used by abstract exported types are made
exported when compiling to C. This ensures that the
base_type_infos are exported, avoiding link errors.

tests/general/Mmakefile:
Add a comment (saying that the problem with string_test.m in
this directory also occurs for tests/hard_coded/mode_choice.m).
Estimated hours taken: 3
tests/Mmake.common:
Add support for setting `MLFLAGS-foo' to alter the `MLFLAGS'
used for compiling `foo'.
tests/general/Mmakefile:
Set `MLFLAGS-string_test' to `--no-strip', to work around a bug
(probably in the Solaris linker) that shows up when this test
is run on kryten with options `-O1 --opt-space' in grade `none'.
Estimated hours taken: 0.25
tests/general/Mmake:
Re-enable the `space.m' test, since it seems to work now.
tests/general/space.m:
Add a missing `:- import_module char'.
Estimated hours taken: 0.25
test/general/mode_inf_bug.m:
Remove `:- import_module time', since (a) it was not needed
and (b) the `time' module has been renamed `benchmarking'.

Changes to make array_test.m run under NU-Prolog.
tests/general/array_test.m:
Remove one function call (use the predicate version) and
replace calls to io__write with their typed versions.
Estimated hours taken: 6
The main purpose of this change is to rename array.m as bt_array.m, and
uniq_array.m as array.m. The interfaces of those two modules have grown
slightly so that they match a little more closely. Details are in the
file NEWS.
The implementation of bt_array (formerly array) has been changed to use
a slightly more efficient implementation.

Fix some places where goal_info fields were not being filled
in correctly.
compiler/hlds_goal.m
Added goal_info_init/4 which takes the nonlocals, instmap_delta
and determinism of the goal. All goal_info_inits after determinism
analysis should probably use this version.
compiler/common.m
compiler/polymorphism.m
Use goal_info_init/4.

Test case.

tests/general/Mmake
Remove the rule for clean, since it removed the .dep files
which meant that mmake realclean didn't remove the executables.
