The main objective of this change is to get bootchecks in the csharp
and java grades to actually build the slice, profiler, deep_profiler
and mfilterjavac directories, which (due to the bug this diff fixes)
they weren't doing before.
However, since one side effect of this change is to eliminate
one source of annoying warnings from mmake about references to undefined
variables, a subsidiary objective is to eliminate other sources of such
warnings as well, which mostly come from the rules for making tags files.

When creating stage 3, the bootcheck builds, in each directory,
only the files that it wants to compare against their stage 2 versions.
This means that it wants to build all the .c, .cs or .java files,
which it does via the cs, css and javas mmake targets.
The correct definitions of the rules of these targets depends on
whether mmc --make is being used or not, so we need at least two
sets of definitions: one for mmc --make, and for no mmc --make,
and conditionally selecting the appropriate one. The latter definition
has the problem that it refers to mmake variables that are intended
to be defined in .dv files created by mmc --generate-dependencies,
but until that has been run, those mmake variables are undefined.
Until now, the only directories that had both the mmc --make
and the no mmc --make definitions were the ones needed to build
the compiler. Bootchecks in the csharp and java grades, which
always use --make make, got errors when they tried to build
the directories that bootcheck builds after the compiler:
the slice, profiler, deep_prof and mfilterjavac directories.
This diff ensures that all directories we build in bootcheck
get all both versions of the os, cs, css, and javas targets.
In fact, they get two subversions of the no mmc --make version:
one for use in the presence of .dv files, and one for use in their
absence. The latter just builds the .dv files and invokes mmake
again. This avoids one source of warnings about undefined mmake
variables.
To avoid another source, make the rules for tags files and their
proxies depends on *.m instead of mmake variables such as $(mcov.ms),
since this makes sense even before making dependencies. The only price
is that any untracked Mercury source files in the directory have to
either be given some other suffix, or moved somewhere else.
Where relevant, make the mtags invocation prefer the master versions
of files that are copied from the mdbcomp directory to other directories,
since this is the only writeable version.
Make the os and cs rules consistently NOT build the _init.[co] files.
The way we use those files in bootcheck, we never need them;
when we need them, the right target to give is the executable anyway.
In the slice directory, don't put mcov between mtc_union and mtc_diff.
Eliminate unnecessary duplication, e.g. of sources in rules.
Eliminate double negatives in conditionals.
Fix formatting.

if they are ever fixed. The aux target is empty for now; the depend_aux
target does make dependencies for both aux programs (since that still
works, and we want to keep it that way).

Fix some problems that were preventing the system from compiling properly with
MSVC.
(1) Visual Studio 2013 no longer includes the files NtWin32.Mak and Win32.Mak
which are required for building the Boehm GC with MSVC. (This appears to be an
issue with upstream Boehm as well.) The workaround here is to reference the
copies of this files included with the Windows 7 SDK. (This appears to be the
official Microsoft workaround for dealing with this problem for now.)
(2) Disable support for `--c-debug' when using MSVC. Using this option causes
MSVC to emit .pdb (Program Data Base), that contain the symbol information for
an object files. This causes a variety of problems:
(i) parallel builds are contending for the vc*.pdb file shared by all the
object files in a directory causing compilation to abort. (Compiling with
the -FS option is another solution to this -- it causes the compiler to
serialize access to the .pdb file -- but at the cost of slowing down
compilation.)
(ii) .pdb files are not cleaned up by realclean; compilation will abort
if a pdb file generated by a different version of MSVC is encountered.
(iii) we don't install the .pdb files alongside the libraries anyway.
This can be a source of linker warnings. (And shutting up the Microsoft
linker seems to be very difficult indeed ...)
(iv) compiling with -Zi (apparently) inhibits some C compiler optimizations.
Compiling with the older -Z7 (MSVC 7 style debugging info) option is another
alternative. Using that option causes MSVC to include symbol information in
the object files, instead of in a separate file.
For now (i.e. the 14.01 release), disabling `--c-debug' for MSVC is the
simplest way of addressing the above issues.

There are some modification for the nondet transformation. When a retry of a
nondet procedure A is asked during the execution of the program, a choicepoint
is left behind and the execution start the retry on procedure B. When the retry
on B is finished, the compiler come back at the choicepoint and finish the call
of the procedure A. This give a wrong number of event.
The proposed solution is: when a retry is asked in a nondet procedure named A
at an exit port, the debugger do not execute any operation until it reach the
fail of the procedure A. It is only at this moment that the execution of B
begin.
If user use a predicate like solutions.unsorted_solutions, he will obtain more
than one time the same solution. The use of solutions is right because it
remove the duplicates

Move the ssdb transformation to after the higher order specialisation
pass to work around a compiler abort. The higher order specialisation
removes predicates which are used to "force the production of

the specialised version be `p1'. Then remove `p'. But due to the ssdb
transformation, `p1' will contain a call to `p', in order to support
retry.

possible.

Remove most of the junk from the command lines executed by make when building
the compiler and by bootcheck when building test cases. We do this by moving
the junk into files consulted via the --flags option.
After this change, it is actually possible to see in a glance not just which
files are being compiled but also with which options. The size of the output
(measured in bytes) from a bootcheck is now only about 40% of what is was
before.

Make it easier to use shared libraries on x86 with
`mmc --make'.
There is now a third kind of object file, `.lpic_o'.
These files are compiled with `--pic-reg' but not with
CFLAGS_FOR_PIC, so they can be linked with shared Mercury
libraries.
On x86, executables which are linked with shared Mercury
libraries now depend on $(main_module.lpic_os), not
$(main_module.os).
This doesn't work with Mmake because ml doesn't know
which libraries are Mercury libraries, so it can't

This is part 2 of a change that provides a register of all the types defined
in the program.
util/mkinit.c:
After part 1 of this change, each compiler-generated module has three
initialization functions: the old one (to register label addresses
etc), one to register type_ctor_infos, and one to register module
layouts for the debugger. However, only the first was invoked from
the mkinit generated <mainmodule>_init.c file.
This change invokes the other two as well. One complication is that
hand-written "modules" do not have the two new kinds of initialization
functions, so only their first initialization function should be
called. We do this by requiring those "modules" to have one of two
specific forms: an initial prefix of either sys_init or
mercury_sys_init.
scripts/c2init.in:
Rerrange the mechanism we use to allow the overriding of the locations
of the init files to be passed to mkinit. The previous mechanism used
a single environment variable, MERCURY_MOD_LIB_MODS, to hold the names
of these init files. While the default setting of this variable was
conditional on whether the --trace option was given to c2init
(including the init file for the browser only with --trace),
there was no way to override the default value in a similarly
conditional manner. This is now a problem, because including the
browser init file in the list of init files passed to mkinit will
cause mkinit to emit code that causes the browser's modules to be
linked in, without also linking in the libraries (e.g. -ldl) on which
the browser depends. The reason why this hasn't bitten us earlier
is that the code that drags in the browser was #ifdef'ed out
in the first initialization function; the reason why it would
bite us now is that it is *not* #ifdef'ed out in the second
initialization function (the one that register type_ctor_infos).
The new mechanism uses two environment variables, MERCURY_MOD_LIB_MODS
and MERCURY_TRACE_LIB_MODS, with the first normally containing
the filenames of the init files of the runtime and library directories
and the second the filename of the init file of the browser directory.
The value of the second environment variable is passed to mkinit
only if c2init is invoked with the --trace flag.
There is also a new environment variable MERCURY_TRACE_LIB_DIR,
which has a role parallel to MERCURY_MOD_LIB_DIR.

would require complicating mkinit.c considerably.
runtime/mercury_wrapper.c:

Introduce two new directories, trace and browser, containing libraries
holding the C and Mercury code of the debugger respectively. (Although
the browser directory does not have a browser in it yet, the browser
should soon become its biggest component.) Take the opportunity to
rename the existing libraries, for consistency.
After this change, the linking order becomes:
the object of the auto-generated init file
program object files
trace library (libmer_trace.a)
browser library (libmer_browser.a)
standard library (libmer_std.a)
runtime library (libmer_rt.a)
Boehm collector (libgc.a)
To avoid circularities, libraries cannot contain direct calls to
any routines that are defined in libraries (or object files) that
occur earlier in the above list. Any such calls must be made into
indirect calls via function pointers.
In particular, there was a circularity caused by the library calling
MR_trace() which invokes the tracer which in turn invokes the
library. This circularity was broken by having MR_trace(),
which is defined in the runtime, call the tracer indirectly via
a global variable named MR_trace_func_ptr. This global variable
is initialized by the auto-generated *_init.c file.
To avoid linking in the tracer even when it is not being used,
this global variable is only set to point to MR_trace_real()
if you're using a debugging grade or if c2init was invoked
with the `-t' flag. Otherwise it is set to MR_trace_fake()
which just prints an error message telling the user to
rebuild the executable with debugging enabled.

Use $(cs_subdir), $(os_subdir) etc. to avoid the code
duplication created by my previous change to handle
--use-subdirs.
Also add lots of comments, and reorder the code
in a more logical order.
Mmakefile:
library/Mmakefile:
compiler/Mmakefile:
profiler/Mmakefile:
tests/term/Mmakefile:
tests/valid/Mmakefile:
Use $(cs_subdir), $(os_subdir) etc. to fix a few hard-coded
file-names (e.g. *.dep, *_init.[co], tree234.o) that were
used in some of the rules.
library/Mmakefile:
Add `rm -f tags' to the rule for `mmake realclean'.
tools/bootcheck:
Add `--use-subdirs' option (defaults to setting of the
MMAKE_USE_SUBDIRS environment variable).
Change the code which compares the stage2 & stage3 C files
to use the appropriate location for them based on the
setting of this option.

Add support for stack dumps, do a stack dump from error/1.
compiler/Mmakefile:
library/Mmakefile:
profiler/Mmakefile:
runtime/Mmakefile:
Insert EXTRA_MGNUCFLAGS before CFLAGS or EXTRA_CFLAGS
becasue mgnuc stops processing its options when it
encounters a non-mgnuc option.
library/require.m:
Call MR_dump_stack if error is called.
runtime/Mmakefile:
runtime/mercury_imp.h:
Add #includes of new files.
runtime/mercury_type_info.h:
Remove conditional definition of MR_STATIC_CODE_ADDRESSES
(moved into mercury_conf.h.in).
runtime/mercury_accurate_gc.h:
Remove stack_layout stuff, leave this file for accurate
GC specific definitions.
runtime/mercury_conf.h.in:
Add conditional definitions of MR_INSERT_LABELS,
MR_USE_STACK_LAYOUTS, MR_NEED_INITIALIZATION_CODE and
MR_STATIC_CODE_ADDRESSES, depending on various other options.
runtime/mercury_goto.h:
Insert labels into label table if MR_INSERT_LABELS is defined,
rather than NATIVE_GC.
util/mkinit.c:
Initialize if MR_NEED_INITIALIZATION_CODE is defined, rather than
NATIVE_GC.
runtime/mercury_stack_layout.h:
All the old stack layout definitions from mercury_accurate_gc.h.
Add code for MR_DETISM_DET_CODE_MODEL.
runtime/mercury_stack_trace.c:
runtime/mercury_stack_trace.h:
Implement MR_dump_stack which just provides a dump of the stack
as far as possible.
Set MR_INSERT_LABELS and MR_USE_STACK_LAYOUTS if MR_STACK_TRACE
is set.
runtime/mercury_grade.h:
Add _strce if stack tracing is enabled in the grade. This
might not be a permanent change.
runtime/mercury_ho_call.c:
Remove unused label declarations.
scripts/mgnuc.in:
Add --stack-trace and --no-stack-trace options.
Consolidate some duplicate code.

Fix a bug that broke grades `*.gc.prof.tr'.
runtime/Mmakefile:
library/Mmakefile:
compiler/Mmakefile:
profiler/Mmakefile:
When deciding whether to link with -lgc or -lgc_prof,
match against `*.gc*.prof*' rather than `*.gc*.prof'.
^
runtime/Mmakefile:
library/Mmakefile:
compiler/Mmakefile:
profiler/Mmakefile:
Match $(GRADE) against `*.gc*' rather than `*.gc', so that it
will link in the GC library for grades such as `asm_fast.gc.tr'.
