f6fafa150d Fix Mantis bug 314 for temp frames created by nondet procedures.
Also fix some bugs in related code, and improve the related debugging
infrastructure.

-------------------

runtime/mercury_stacks.[ch]:
   Fix bug 314 for temp frames created by nondet procedures. The fix will
   probably also work for *det* procedures that create temp frames on the
   nondet stack, but I can't think of a way to test that, because det
   procedures create such frames only in very specific circumstances,
   and I cannot think of a way to nest a recursive call inside those
   circumstances.

   The problem was that when we were creating new temp frames on
   the nondet stack, we did not check whether the current nondet stack segment
   had room for them. We now do.

   The stack trace tracing code needs to know the size of each nondet stack
   frame, since it uses the size to classify frames as temp or ordinary.
   The size is given by the difference in address between the address of the
   frame and the address of the previous frame. This difference would yield
   an incorrect size and hence an incorrect frame classification if a temp
   frame were allowed to have a frame on a different segment as its
   immediate predecessor.

   We prevent this by putting an ordinary (i.e. non-temp) frame at the bottom
   of every new nondet stack segment as a sentinel. We hand-build this frame,
   since it is not an "ordinary" ordinary frame. It is not created by a call,
   so it has no meaningful success continuation, and since it does not make
   any calls, no other frame's success continuation can point to it either.

   If backtracking reaches this sentinel frame, we use this fact to free
   all the segments beyond the one the sentinel frame is in, but keep the
   frame the sentinel frame is in, since we are likely to need it again.

   Document the reason why MR_incr_sp_leaf() does not have to check
   whether a new stack segment is needed. (See the fix to llds_out_instr.m
   below.)

runtime/mercury_stack_trace.[ch]:
   When traversing the nondet stack, treat the sentinel frame specially.
   We have to, since it is an ordinary frame (i.e. it is not a temp frame),
   but it is not an "ordinary" ordinary frame: it does not make calls,
   and hence calls cannot return to it, and it does not return to any
   other frame either. It therefore does not have the layout structures
   (label and proc) that the nondet stack traversal expects to find.

   Fix an old bug: the nondet stack traversal used a simple directional
   pointer comparison to check whether it has reached the bottom of the nondet
   stack. This is NOT guaranteed to work in the presence of stack segments:
   depending on exactly what addresses new stack segments get, a stack frame
   can have an address BELOW the address of the initial stack frame
   even if it is logically ABOVE that stack frame.

   Another old bug was that a difference between two pointers, which could
   be 64 bit, was stored in an int, which could be 32 bit.

   The nondet stack traversal code used a similar directional comparison
   to implement optionally stopping at an arbitrary point on the nondet stack.
   Fixing this facility (the limit_addr parameter of MR_dump_nondet_stack)
   while preserving reasonable efficiency would not be trivial, but it would
   also be pointless, since the facility is not actually used. This diff
   deletes the parameter instead.

   Move some loop invariant code out of its loop.

trace/mercury_trace_cmd_developer.c:
trace/mercury_trace_external.c:
   Don't pass the now-deleted parameter to mercury_stack_trace.c.

runtime/mercury_wrapper.c:
   Record the zone of the initial nondet stack frame, since the fix
   of mercury_stack_trace.c needs that info, and it is much more efficient
   to set it up just once.

   Compile the new test case with the options it needs.

-------------------

runtime/mercury_wrapper.c:
   The compiler knows the number of words in a stack frame it is creating,
   not necessarily the number of bytes (though it could put bounds on that
   from the number of tag bits). Since this size must sync with the runtime,
   change the runtime's variable holding this size to also be in words.

   Note that similar changes would also be beneficial for other sizes.

compiler/llds_out_instr.m:
   Conform to the change in mercury_wrapper.c, fixing an old bug
   (mercury_wrapper.c reserved 128 BYTES for leaf procedures, but
   llds_out_instr.m was using that space for procedures whose frames
   were up to 128 WORDS in size.)

compiler/mercury_memory.c:
   Conform to the change in mercury_wrapper.c.

-------------------

runtime/mercury_memory_zones.h:
   Instead of starting to use EVERY zone at a different offset, do this
   only for the INITIAL zones in each memory area, since only on these
   is it useful. When the program first starts up, it WILL be using
   the initial parts of the det stack, nondet stack and heap, so it is
   useful to make sure that these do not collide in the cache. However,
   when we allocate e.g. the second zone in e.g. the nondet stack, we are
   no more likely to be beating on the initial part of any segment
   of the det stack than on any other part of such segments.

   If a new debug macro, MR_DEBUG_STACK_SEGMENTS_SET_SIZE is set (to an int),
   use only that many words in each segment. This allows the segment switchover
   code to be exercised and debugged with smaller test cases.

runtime/mercury_conf_param.h:
   Document the MR_DEBUG_STACK_SEGMENTS_SET_SIZE macro.

   Convert this file to four-space indentation with tabs expanded.

-------------------

runtime/mercury_overflow.h:
   Make abort messages from overflows and underflows more useful by including

ecf1ee3117 Add a mechanism for growing the stacks on demand by adding new segments
Estimated hours taken: 20
Branches: main

Add a mechanism for growing the stacks on demand by adding new segments
to them. You can ask for the new mechanism via a new grade component, stseg
(short for "stack segments").

The mechanism works by adding a test to each increment of a stack pointer (sp
or maxfr). If the test indicates that we are about to run out of stack, we
allocate a new stack segment, allocate a placeholder frame on the new segment,
and then allocate the frame we wanted in the first place on top of the
placeholder. We also override succip to make it point code that will (1)
release the new segment when the newly created stack frame returns, and then
(2) go to the place indicated by the original, overridden succip.

For leaf procedures on the det stack, we optimize away the check of the stack
pointer. We can do this because we reserve some space on each stack for the
use of such stack frames.

My intention is that doc/user_guide.texi and NEWS will be updated once we have
used the feature ourselves for a while and it seems to be stable.

	When printing the offsets of pointers into the det and nondet stacks,
	print the number of the segment the pointer points into (unless it is
	the first, in which case we suppress this in the interest of brevity
	and simplicity).

	Make all the functions in this module take a FILE * as an input
	argument; don't print to stdout by default.

Mmake.workspace:
	Fix an old bug that prevented bootcheck from working in the new grade:
	when computing the gc grade, use the workspace's version of ml (which
	in this case understands the new grade components), rather than the
	installed ml (which does not).

	(This was a devil to track down, because neither make --debug nor
	strace on make revealed how the installed ml was being invoked,
	and there was no explicit invocation in the Makefile either; the error
	message appeared to come out of thin air just before the completion
	of the stage 2 library. It turned out the invocation happened
	implicitly, as a result of expanding a make variable.)

1ed891b7b1 Introduce a mechanism for extending the det and nondet stacks when needed.
Estimated hours taken: 24
Branches: main

Introduce a mechanism for extending the det and nondet stacks when needed.
The mechanism takes the form of a new grade component, .exts ("extend stacks").

While the new mechanism may be useful in its own right, it is intended mainly
to support a new implementation of minimal model tabling, which will use a
separate Mercury context for each distinct subgoal. Each context has its own
det and nondet stack. Clearly, we can't have hundreds of contexts each with
megabyte sized det stacks. The intention is that the stacks of the subgoals
will start small, and be expanded when needed.

The runtime expansion of stacks doesn't work yet, but it is unnecessarily
hard to debug without an installed compiler that understands the new grade
component, which is why this diff will be committed before that is fixed.

runtime/mercury_memory_zones.h:
	Add MR_ prefixes to the names of the fields of the zone structure.

	Record not just the actual size of each zone, which includes various
	kinds of buffers, but also the desired size of the zone exclusive of
	buffers.

	Format the documentation of the zone structure fields more
	comprehensibly.

runtime/mercury_memory_zones.c:
	Instead of implementing memalign if it is not provided by the operating
	system, implement a function that allows us to reallocate the returned
	area of memory.

	Provide a prototype implementation of memory zone extension. It doesn't
	work yet.

	Factor out the code for setting up redzones, since it is now needed
	in more than place.

	Convert to four space indentation.

	Make the debugging functions a bit more flexible.

	the old stack. In .exts grades, these instructions will save not a
	pointer but the offset of maxfr from the start of the nondet stack,

	the new behaviour is for implementors.

runtime/mercury_prof.[ch]:
runtime/mercury_prof_time.[ch]:

	containing stuff that is only relevant to the old profiler.

runtime/mercury_prof.[ch]:
runtime/mercury_strerror.[ch]:

	since all but one of these in each directory will be overwritten
	anyway.

	Add support for turning on --keep-objs by default in a workspace.

tools/speedtest:
	Preserve any deep profiling data files created by the tests.

tests/*/*/Mmakefile:
	In deep profiling grades, switch off the tests that test features

2f737704b9 Add some Mmake rules to the runtime and some code to tools/bootcheck
Estimated hours taken: 16

Add some Mmake rules to the runtime and some code to tools/bootcheck
so that we automatically check that the namespace remains clean.
Also add some `MR_' prefixes that Zoltan missed in his earlier change.

tools/bootcheck:
	Add an option, which is enabled by default, to
	build the check_namespace target in the runtime.

runtime/RESERVED_MACRO_NAMES:
	New file.  Contains a list of the macros names that
	don't start with `MR_' or the like.

runtime/Mmakefile:
	Change the rule for `check_headers' so that it checks for macros
	that don't occur in the RESERVED_MACRO_NAMES files, as well as not
	starting with `MR_' prefixes, and reports errors for such macros.
	Also add a rule for check_objs that checks whether the object
	files define any global symbols that don't have the right prefixes,
	and a rule `check_namespace' that does both of the above.

runtime/mercury_bootstrap.h:
	#include "mercury_types.h" and "mercury_float.h",
	to ensure that this header file is self-contained.
	Also make sure that all the old names are disabled if you
	compile with `-DMR_NO_BACKWARDS_COMPAT'.

runtime/mercury_context.c:
runtime/mercury_thread.h:
runtime/mercury_thread.c:
	Use `bool' rather than `MR_Bool' for the argument to
	MR_check_pending_contexts() and the return type of
	MR_init_thread(), since these are C bools, not Mercury
	bools, and there's no requirement that they have the
	same size as MR_Integer.

090552c993 Make everything in the runtime use MR_ prefixes, and make the compiler
Estimated hours taken: 10

Make everything in the runtime use MR_ prefixes, and make the compiler
bootstrap with -DMR_NO_BACKWARDS_COMPAT.

runtime/mercury_*.[ch]
	Add MR_ prefixes to all functions, global variables and almost all
	macros that could pollute the namespace. The (intentional) exceptions
	are

	1. some function, variable, type and label names that already start
	   with MR_, mercury_, Mercury or _entry;
	2. some standard C macros in mercury_std.h;
	3. the macros used in autoconfiguration (since they are used in scripts
	   as well as the runtime, the MR_ prefix may not be appropriate for
	   those).

	In some cases, I deleted things instead of adding prefixes
	if the "things" were obsolete and not user visible.

runtime/mercury_bootstrap.h:
	Provide MR_-less forms of the macros for bootstrapping and for
	backward compatibility for user code.

runtime/mercury_debug.[ch]:
	Add a FILE * parameter to a function that needs it.

compiler/code_info.m:
compiler/export.m:
compiler/fact_table.m:
compiler/llds.m:
compiler/llds_out.m:

library/*.m:
	Add MR_ prefixes to handwritten code.

trace/mercury_trace_*.c:
util/mkinit.c:
	Add MR_ prefixes as necessary.

extras/concurrency/semaphore.m:
	Add MR_ prefixes as necessary.

c315607690 Clean up the handling of configuration macros in the runtime.
Estimated hours taken: 4

Clean up the handling of configuration macros in the runtime.

runtime/mercury_conf.h.in:
runtime/mercury_conf_param.h:
	Move the code to set configuration parameters based on
	the values of other configuration parameters from
	mercury_conf.h.in to a new file mercury_conf_param.h,
	because otherwise autoconf munges the code in undesirable ways
	(it replaces all `#undef <foo>' statements with `/* #undef <foo> */').

runtime/mercury_conf.h.in:
runtime/mercury_conf_param.h:
runtime/*.h:
runtime/*.c:
	Use more meaningful names, starting with the usual `MR_' prefix,
	for various configuration parameters:
		- replace the existing configuration macros SPEED with
		  three new macros MR_CHECK_OVERFLOW, MR_LOWLEVEL_DEBUG,
		  and MR_DEBUG_NONDET_STACK;
		- rename DEBUG_GOTOS as MR_DEBUG_GOTOS, and make it
		  implied by MR_LOWLEVEL_DEBUG;
		- rename DEBUG_LABELS as MR_CHOOSE_ENTRY_POINT.

	(But there are still many configuration parameters that don't
	start with `MR_', I'm afraid.)

runtime/CFLAGSFILE:
runtime/mercury_conf_param.h:
	Removed CFLAGSFILE.  The documentation there was had rotted badly.
	I moved most of it to mercury_conf_param.h where hopefully
	it will stand a better chance of being kept up-to-date.
	I added documentation for the configuration parameters added in
	the last year or so.  The documentation here now covers
	every configuration parameter that we use; please keep it that way!

runtime/mercury_debug.h:
	Fix a bug: there was a misplaced "#endif".

runtime/mercury_stack_trace.c:
	Fix yet another misspelling of "deterministic".

7ce7d489a2 Cleaned up runtime directory.
Estimated hours taken: 2

Cleaned up runtime directory.

runtime/*.c:
	- Renamed all .c files as mercury_*.c
	  Some have been renamed to make their purpose clearer.
	  	call.mod -> mercury_ho_call.c

runtime/*.h:
	- Moved contents of .h files to mercury_*.h
	- *.h now contain #include mercury_*.h. They be removed later.
	- Updated references to conf.h -> mercury_conf.h

runtime/conf.h.in:
	- Renamed conf.h.in as mercury_conf.h.in.
	  Didn't leave a forwarding header for this one, as conf.h was
	  never part of the repository anyway.

runtime/Mmakefile:
	- Convert lists to one-per-line lists.
	- Add mercury_accurate_gc.h to HDRS.
	- Remove all .mod files
	- Make sure runtime.init uses the ORIG_CS not MOD_CS.
	- Fix the rules for "clean_o" and "clean_mod_c", which used
	  wildcards like "*.o" to remove files.  The one that removed
	  all .c files corresponding with *.mod, instead of using MOD_CS
	  was particularly vicious.
	- Cope with the file renamings.

configure.in:
	- Cope with the file renamings.
