Currently, we return a placeholder string ("foreignxx") if we attempt to look
up the functor of a foreign type in the C# or Java grades. For C, we return a
string of the form:
<<foreign(Name, Rep)>>
where Name is the type's Mercury name and Rep is its "value" as results from
casting it to (void *) and then using sprintf's %p conversion specifier. Do
something similar for both the C# and Java grades, except that for Rep we
return the output of the calling the toString() (ToString()) method. If the
object in question is a null reference then we return "null" for Rep.

As above. This mostly involved two things.
The first was grouping foreign_procs by predicate instead of by language.
In a few cases, this revealed that some predicates *had* no foreign_proc
for a language, while related predicates did have one that just aborted
if called. This diff adds similar aborting foreign_procs to predicate/
language combinations that were missing them, when this seemed obviously
the right thing to do.
The second was moving pragmas about a predicate from the middle of the
block of clauses of that predicate to the start of that block.
The above predicates currently escape all of the C0 control characters (+
Delete). This change modifies them to escape all of the characters in the
Unicode category `Other,control' using backslash escapes when they exist and
octal escapes otherwise.

Fix inconsistencies between (a) the order in which functions and predicates
are declared, and (b) the order in which they are defined.
In most of these modules, either the order of the declarations
or the order of the definitions made sense, and I changed the other
to match. In a few modules, neither made sense, so I changed *both*
to an order that *does* make sense (i.e. it has related predicates
together).
In some places, put dividers between groups of related
functions/predicates, to make the groups themselves more visible.
In some places, fix comments or programming style, give some auxiliary
(non-exported) predicates better names, or delete some unneeded module
qualifications.
In some places, have the function form of a procedure forward
the work to the predicate form, instead of vice versa, where this is
more natural (usually because it allows the use of state variables).
However, this is the only kind of "algorithmic" change in this diff;
the rest is just moving code around.

Branches: main
Implement a new form of memory profiling, which tells the user what memory
is being retained during a program run. This is done by allocating an extra
word before each cell, which is used to "attribute" the cell to an
allocation site. The attribution, or "allocation id", is an address to an
MR_AllocSiteInfo structure generated by the Mercury compiler, giving the
procedure, filename and line number of the allocation, and the type
constructor and arity of the cell that it allocates.
The user must manually instrument the program with calls to
`benchmarking.report_memory_attribution', which forces a GC and summarises
the live objects on the heap using the attributions. The mprof tool is
extended with a new mode to parse and present that data.
Objects which are unattributed (e.g. by hand-written C code which hasn't
been updated) are still accounted for, but show up in profiles as "unknown".
Currently this profiling mode only works in conjunction with the Boehm
garbage collector, though in principle it can work with any memory allocator
for which we can access a list of the live objects. Since term size
profiling relies on the same technique of using an extra word per memory
cell, the two profiling modes are incompatible.
The output from `mprof -s' looks like this:
------ [1] some label ------
cells words cumul procedure / type (location)

for functor numbers, as in the C backends.
- Change the representation of type_ctor_descs, which are now different from
the representation of type_ctor_infos in the case of variable arity types
(higher order types and tuples). This is necessary so we can get the arity
from a variable arity type_ctor_desc.

Improvements for bitmap.m, to make it useable as a general container
for binary data.
library/bitmap.m:
runtime/mercury_bitmap.c:
runtime/mercury_bitmap.h:
Specialize the representation of bitmaps to an array of unsigned
bytes defined as a foreign type.
This is better than building on top of array(int) because it:
- is better for interfacing with foreign code
- has a more sensible machine-independent comparison order
(same as array(bool))
- avoids storing the size twice
- has more efficient copying, unification, comparison and tabling
(although we should probably specialize the handling of array(int)
and isomorphic types as well)
- uses GC_MALLOC_ATOMIC to avoid problems with bit patterns that look
like pointers (although we should do that for array(int) as well)
XXX The code for the Java and IL backends is untested.
Building the library in grade Java with Sun JDK 1.6 failed (but
at least passed error checking), and I don't have access to a
copy of MSVS.NET. The foreign code that needs to be tested is
trivial.
Add fields `bit', `bits' and `byte' to get/set a single bit,
multiple bits (from an int) or an 8 bit byte.
Add functions for converting bitmaps to hex strings and back,
for use by stream.string_writer.write and deconstruct.functor/4.
bitmap.intersect was buggy in the case where the input bitmaps
had a different size. Given that bitmaps are implemented with
a fixed domain (lookups out of range throw an exception), it
makes more sense to throw an exception in that case anyway,
so all of the set operations do that now.
The difference operation actually performed xor. Fix it and
add an xor function.
library/version_bitmap.m:
This hasn't been fully updated to be the same as bitmap.m.
The payoff would be much less because foreign code can't
really do anything with version_bitmaps.
Add a `bit' field.
Deprecate the `get/2' function in favour of the `bit' field.
Fix the union, difference, intersection and xor functions
as for bitmap.m.
Fix comparison of version_arrays so that it uses the same
method as array.m: compare size then elements in order.
The old code found version_arrays to be equal if one was
a suffix of the other.

Implement the infrastructure for term size profiling. This means adding two
new grade components, tsw and tsc, and implementing them in the LLDS code
generator. In grades including tsw (term size words), each term is augmented
with an extra word giving the number of heap words it contains; in grades
including tsc (term size cells), each term is augmented with an extra word
giving the number of heap cells it contains. The extra word is at the start,
at offset -1, to leave almost all of the machinery for accessing the heap
unchanged.
For now, the only way to access term sizes is with a new mdb command,
"term_size <varspec>". Later, we will use term sizes in conjunction with
deep profiling to do experimental complexity analysis, but that requires
a lot more research. This diff is a necessary first step.
The implementation of term size profiling consists of three main parts:
- a source-to-source transform that computes the size of each heap cell
when it is constructed (and increments it in the rare cases when a free
argument of an existing heap cell is bound),
- a relatively small change to the code generator that reserves the extra
slot in new heap cells, and
- extensions to the facilities for creating cells from C code to record
the extra information we now need.
The diff overhauls polymorphism.m to make the source-to-source transform
possible. This overhaul includes separating type_ctor_infos and type_infos
as strictly as possible from each other, converting type_ctor_infos into
type_infos only as necessary. It also includes separating type_ctor_infos,
type_infos, base_typeclass_infos and typeclass_infos (as well as voids,
for clarity) from plain user-defined type constructors in type categorizations.
This change needs this separation because values of those four types do not
have size slots, but they ought to be treated specially in other situations
as well (e.g. by tabling).
The diff adds a new mdb command, term_size. It also replaces the proc_body
mdb command with new ways of using the existing print and browse commands
("print proc_body" and "browse proc_body") in order to make looking at
procedure bodies more controllable. This was useful in debugging the effect
of term size profiling on some test case outputs. It is not strictly tied
to term size profiling, but turns out to be difficult to disentangle.
compiler/size_prof.m:
A new module implementing the source-to-source transform.
compiler/notes/compiler_design.html:
Mention the new module.
compiler/transform_hlds.m:

Extend construction unifications with an optional slot for recording
the size of the term if the size is a constant, or the identity of the
variable holding the size, if the size is not constant. This is
needed by the source-to-source transform.
compiler/quantification.m:
Treat the variable reference that may be in this slot as a nonlocal
variable of construction unifications, since the code generator needs
this.
compiler/compile_target_code.m:

compiler/options.m:

compiler/builtin_ops.m:

compiler/make_hlds.m:

type_ctor_infos to add_to_construct.m. Rewrite their documentation
to make it more detailed.
Make orders of arguments amenable to the use of state variable syntax.
Consolidate knowledge of which type categories have builtin unify and
compare predicates in one place.
Add code to leave the types of type_ctor_infos alone: instead of
changing their types to type_info when used as arguments of other
type_infos, create a new variable of type type_info instead, and
use an unsafe_cast. This would make the HLDS closer to being type
correct, but this new code is currently commented out, for two
reasons. First, common.m is currently not smart enough to figure out
that if X and Y are equal, then similar unsafe_casts of X and Y
are also equal, and this causes the compiler do not detect some
duplicate calls it used to detect. Second, the code generators
are also not smart enough to know that if Z is an unsafe_cast of X,
then X and Z do not need separate stack slots, but can use the same
slot.
compiler/type_util.m:
Add utility predicates for returning the types of type_infos and
type_ctor_infos, for use by new code in polymorphism.m.
Move some utility predicates here from other modules, since they
are now used by more than one module.
Rename the type `builtin_type' as `type_category', to better reflect
what it does. Extend it to put the type_info, type_ctor_info,
typeclass_info, base_typeclass_info and void types into categories
of their own: treating these types as if they were a user-defined
type (which is how they used to be classified) is not always correct.
Rename the functor polymorphic_type to variable_type, since types
such as list(T) are polymorphic, but they fall into the user-defined
category. Rename user_type as user_ctor_type, since list(int) is not
wholly user-defined but falls into this category. Rename pred_type
as higher_order_type, since it also encompasses functions.
Replace code that used to check for a few of the alternatives
of this type with code that does a full switch on the type,
to ensure that they are updated if the type definition ever
changes again.
compiler/pseudo_type_info.m:
Delete a predicate whose updated implementation is now in type_util.m.
compiler/mlds_to_c.m:

Require interface typeinfo liveness when term size profiling is
enabled.
Add term_size_profiling_builtin.increase_size as a
no_type_info_builtin.
compiler/hlds_out.m:
Print the size annotations on unifications if HLDS dump flags call
for unification details. (The flag test is in the caller of the
modified predicate.)
compiler/llds.m:
Extend incr_hp instructions and data_addr_consts with optional fields
that allow the code generator to refer to N words past the start of

runtime/mercury_tags.h:
Define new macros for constructing typed lists.
Provide macros for preserving the old interface presented by this file
to the extent possible. Uses of the old MR_list_cons macro will
continue to work in grades without term size profiling. In term
size profiling grades, their use will get a C compiler error.
Fix a bug caused by a missing backslash.
runtime/mercury_heap.h:
Change the basic macros for allocating new heap cells to take
an optional offset argument. If this is nonzero, the macros
increment the returned address by the given number of words.
Term size profiling specifies offset=1, reserving the extra
word at the start (which is ignored by all components of the
system except term size profiling) for holding the size of the term.
Provide macros for preserving the old interface presented by this file
to the extent possible. Since the old MR_create[123] and MR_list_cons
macros did not specify type information, they had to be changed
to take additional arguments. This affects only hand-written C code.
Call new diagnostic macros that can help debug heap allocations.
Document why the macros in this files must expand to expressions
instead of statements, evn though the latter would be preferable
(e.g. by allowing them to declare and use local variables without
depending on gcc extensions).
runtime/mercury_debug.[ch]:
Add diagnostic macros to debug heap allocations, and the functions
behind them if MR_DEBUG_HEAP_ALLOC is defined.
Update the debugging routines for hand-allocated cells to print the
values of the term size slot as well as the other slots in the relevant
grades.
runtime/mercury_string.h:

runtime/mercury_deconstruct_macros.h:
runtime/mercury_type_info.c:

runtime/mercury_deep_copy_body.h:

runtime/mercury_grade.h:
Handle the two new grade components.
runtime/mercury_conf_param.h:
Document the C macros used to control the two new grade components,
as well as MR_DEBUG_HEAP_ALLOC.
Detect incompatibilities between high level code and profiling.
runtime/mercury_term_size.[ch]:
A new module to house a function to find and return term sizes
stored in heap cells.
runtime/mercury_proc_id.h:
runtime/mercury_univ.h:
New header files. mercury_proc_id.h contains the (unchanged)
definition of MR_Proc_Id, while mercury_univ.h contains the
definitions of the macros for manipulating univs that used to be
in mercury_type_info.h, updated to use the new macros for allocating
memory.
In the absence of these header files, the following circularity
would ensue:
mercury_deep_profiling.h includes mercury_stack_layout.h
- needs definition of MR_Proc_Id
mercury_stack_layout.h needs mercury_type_info.h
- needs definition of MR_PseudoTypeInfo
mercury_type_info.h needs mercury_heap.h
- needs heap allocation macros for MR_new_univ_on_hp
mercury_heap.h includes mercury_deep_profiling.h
- needs MR_current_call_site_dynamic for recording allocations
Breaking the circular dependency in two places, not just one, is to
minimize similar problems in the future.

Add documentation of the new arguments of the print and browse mdb
commands. Since they are for implementors only, the documentation
is commented out.
trace/mercury_trace_vars.[ch]:
Add the functions needed to implement the term_size command, and
factor out the code common to the "size" and "print"/"browse" commands.
Decide whether to print the name of a variable before invoking the
supplied print or browse predicate on it based on a flag design for
this purpose, instead of overloading the meaning of the output FILE *
variable. This arrangement is much clearer.
trace/mercury_trace_browse.c:
trace/mercury_trace_external.c:
trace/mercury_trace_help.c:
Supply type information when constructing terms.
browser/program_representation.m:
Since the new library module term_size_prof_builtin never generates
any events, mark it as such, so that the declarative debugger doesn't
expect it to generate any.
Do the same for the deep profiling builtin module.
tests/debugger/term_size_words.{m,inp,exp}:
tests/debugger/term_size_cells.{m,inp,exp}:
Two new test cases, each testing one of the new grades.
tests/debugger/Mmakefile:
Enable the two new test cases in their grades.
Disable the tests sensitive to stack frame sizes in term size profiling
grades.
tests/debugger/completion.exp:
Add the new "term_size" mdb command to the list of command completions,
and delete "proc_body".
tests/debugger/declarative/dependency.{inp,exp}:
Use "print proc_body" instead of "proc_body".
tests/hard_coded/nondet_c.m:
tests/hard_coded/pragma_inline.m:
Use MR_offset_incr_hp instead of MR_incr_hp to ensure that all places
that allocate cells also allocate space for the term size slot if
necessary.
tests/valid/Mmakefile:
Disable the IL tests in term size profiling grades, since the term size
profiling primitives haven't been (and probably won't be) implemented
for the MLDS backends, and handle_options causes a compiler abort
for grades that combine term size profiling and any one of IL, Java
and high level C.
