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.

Delete residual references to the IL backend.
Currently, the compiler's top-level module is the module 'top_level'. This
means that the executable (or Java archive, or assembly) we generate is named
after that. However, the rest of the system requires that the compiler
executable be named 'mercury_compile', so we currently rename it after it is
generated. (At least, we do in C grades, in non-C grades the compiler
"executable" currently has the "wrong" name.) Making this scheme work across
multiple backends and platforms leads to quite a bit of complication in the
build system. This change simplifies matters by repurposing the
'mercury_compile' module to be the new top-level module; this means that the
executable is generated with the correct name to begin with.

Make it possible to run the installed Java version of the compiler by
installing versions of the wrapper scripts for 'mercury_compile' and
'mfilterjavac' that have the CLASSPATH set to point to the installed versions
of the standard library Java archives.
The wrapper script generated in the compiler directory is not suitable for this
because as generated it sets the CLASSPATH relative to the compiler directory,
not the installation directory. Modifying that file is not a good idea since
that will mean that then the compiler cannot be executed in situ. Instead we
provide a handwritten version of the wrapper script in the scripts directory
that is installed in place of the generated one. Ditto for mfilterjavac.
While this does create a small maintenance problem, I think that any other
approach, for example, modifying the generation of wrapper scripts to account
for this, is going to be a larger maintenance problem.

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.

Describe the problem with NtWin32.Mak and Visual Studio 2013 and

used.)
The hlc.gc version of the Mercury compiler exhausts the C stack while compiling
the standard library. This is because the default size of the C stack on
Windows is ridiculously low.
compiler/Mmakefile:
On the x86_64-w64-mingw32 architecture, bump the default size
of the C stack up to something more reasonable.
XXX in the long term, i.e. when we support 64-bit MSVC, we
should add a --stack option to the ml script and use that.

building the compiler.
The main thing this change does not address is the fact that we invoke
the compiler through C code, e.g. main.c in the top-level of the source
tree. This was required by the GCC backend and can now be removed, but
I will do that as a separate change.

Fix an old bug. The action for the target "tags_file_exists", which is

the tags file (whose logical timestamp .compiler_tags represents)
is at least as new as all the .m files, causing it to not actually
remake the tags file, even when it should have.
We now touch .compiler_tags only when rebuilding the tags file.

Fix a performance problem with mmc --make --jobs <n>. It would fork a new
process for each target, whether or not that target was already up-to-date.
For a large program which is mostly up-to-date, this could be very costly.
The main reason it was implemented so was to avoid interprocess communication
which might be non-portable (the only communication was via a sub-process's
exit code).
This patch makes use of IPC to allow the master process to fork off only N-1
worker processes, itself being the last worker. The workers communicate via
shared memory as to which tasks still need doing, and which are completed.
A worker process therefore may work on as many tasks as required before
terminating.
Parallel mmc --make is currently disabled in .par grades. It should be
fairly simple to restore.

Speed up the compiler's handling of code that constructs large ground terms
by specializing the treatment of such code.
This diff reduces the compilation time for training_cars_full.m from 106.9
seconds to 30.3 seconds on alys, my laptop. The time on tools/speedtest
stays pretty much the same.
compiler/hlds_goal.m:
Record the classification of from_ground_term scopes as purely
constructing terms, purely deconstructing them or something other.
Fix an old potential bug: variables inside the construct_how fields
of unifications weren't being renamed along with other variables.
This is a bug if any part of the compiler later looks at those
variables. (I am not sure whether or not this happens.)
compiler/superhomogenous.m:
Provisionally mark newly constructed static terms as being
from_ground_term_construct. Mode checking will either confirm this
or change the scope kind.
compiler/options.m:
compiler/handle_options.m:
Add a new option, from_ground_term_threshold, that allows the user to
set the boundary between ground terms that get scopes and ground terms
do not. I plan to experiment with different settings later.
compiler/modes.m:
Make this classification. For scopes that construct ground terms,
use a specialized algorithm that avoids quadratic behavior.
(It does not access the unify_inst_table, which is where the
factor of N other than the length of the goal list came from.)
The total size of the instmap_deltas, if printed out, still looks like
O(N^2) in size, but due to structure sharing it needs only O(N) memory.
For scopes that construct ground terms, set the determinism information
so that det_analysis.m doesn't have to traverse such scopes.
When handling disjunctions, check whether some nonlocals of the
disjunctions are constructed by from_ground_term_construct scopes.
For any such nonlocals, set their insts to just ground, throwing away
the precise information we have about exactly what function symbols
they and ALL their subterms are bound to. This is HUGE win, since
it allows us avoid spending a lot of time building a huge merge_inst
table, which later passes of the compiler (e.g. equiv_type_hlds) would
then have to spend similarly huge times traversing.
This approach does have a down side. If lots of arms of a disjunction
bind a nonlocal to a large ground term, but a few bind it to a SMALL
ground term, a term below the from_ground_term_threshold, this
optimization won't kick in. That could be one purpose of the new
option. It isn't documented yet; I will seek feedback about its
usefulness first.
compiler/modecheck_unify.m:
Handle the three different kinds of right hand sides separately.
This yields a small speedup, because now we don't test rhs_vars and
rhs_functors (the common right hand sides) for a special case
(goals containing "any" insts) that is applicable only to
rhs_lambda_goals.
compiler/unique_modes.m:
Don't traverse scopes that construct ground terms, since modes.m has
already done everything that needs to be done.
compiler/det_analysis.m:
Don't traverse scopes that construct ground terms, since modes.m has
already done the needed work.
compiler/instmap.m:
Add a new predicate for use by modes.m.
Many predicate names in this module were quite uninformative; give them
informative names.
compiler/polymorphism.m:
If this pass invalidates the from_ground_term_construct invariants,
then mark the relevant scope as from_ground_term_other.
Delete two unused access predicates.
compiler/equiv_type_hlds.m:
Don't traverse scopes that construct ground terms, since modes.m
ensures that their instmap deltas do not contain typed insts, and
thus the scope cannot contain types that need to be expanded.
Convert some predicates to single clauses.
compiler/goal_form.m:
compiler/goal_util.m:
In predicates that test goals for various properties, don't traverse
scopes that construct ground terms when the outcome of the test
is the same for all such scopes.
Convert some predicates to single clauses.
compiler/simplify.m:
Do not look for common structs in from_ground_term_construct scopes,
both because this speeds up the compiler, and because retaining
references to ground terms is in fact a pessimization, not an
optimization. This is because (a) those references need to be stored in
stack slots across calls, and (b) the C code generators ensure that
the cells representing ground terms will be shared as needed.
If all arms of a switch are from_ground_term_construct scopes,
do not merge the instmap_deltas from those arms, since this is
both time-consuming (even after the other changes in this diff)
and extremely unlikely to improve the instmap_delta.
Disable common_struct in from_ground_term_construct scopes,
since for these scopes, it is actually a pessimization.
Do not delete from_ground_term_construct scopes, since many
compiler passes can now use them.
Do some manual deforestation, break up some large predicates,
and give better names to some.
compiler/liveness.m
Special-case the handling from_ground_term_construct scopes. This
allows us to traverse them just once instead of three times, and this
traversal is simpler and faster than any of the three.
In some traversals, we were switching on the goal type twice; once
in e.g. detect_liveness_in_goal_2, and once by calling
goal_expr_has_subgoals. Eliminate the double switching by merging
the relevant predicates. (The double-switching structure was easier
to work with before we had multi-cons-id switches.)
compiler/typecheck.m:
Move a lookup after a test, so we don't have to do it if the test
fails.
Provide a specialized mode for a predicate. This should allow the
compiler to eliminate an argument and a test in the common case.
Note a possible chance for a speedup.
compiler/typecheck_info.m:
Don't apply empty substitutions to the types of a possibly very large
set of variables.
compiler/quantification.m:
Don't quantify from_ground_term_construct scopes. They are created
correctly quantified, and any compiler pass that invalidates that
quantification also removes the from_ground_term_construct mark.
Don't apply empty renamings to a possibly very large set of variables.
Move the code for handling scopes to its own predicate, to avoid
overwhelming the code that handles other kinds of goals. Even from
this, factor out the renaming code, since it is needed only for
some kinds of scopes.
Make some predicate names better reflect what the predicate does.
compiler/pd_cost.m:
For from_ground_term_construct scopes, instead of computing their cost
by adding up the costs of the goals inside, make their cost a constant,
since binding a variable to a static term takes constant time.

Add prefixes on field names to avoid ambiguities.

In loop_inv.m, replace a code structure that updated accumulators
with functions (which prevented the natural use of state variables),
that in lots of places reconstructed the term it had just

shared code for different goal types where possible.

Fix a bug that prevented the compiler from bootstrapping in deep profiling

mercury_deep_profiling.c, which lead to this message:
Mercury runtime: UNWRITTEN nodes: Deep.data file corrupted
Mmake.workspace:
Don't include the ssdb library's init file unconditionally in every
_init.c file we generate; instead include the ssdb library's init file
only in ssdb grades.
The reason why this is needed is that the referenced but unwritten
nodes were the proc layouts of three predicates in the browser
directory. They were not written because the browser library's init
file is (correctly) included in the compiler's _init.c file only if
the browser library is linked into the compiler, i.e. only if the
compiler is compiled in a debug grade. They were referenced by call
site static structures from ssdb/ssdb.m, whose init file was
(incorrectly) being included in the compiler's _init.c file even if
the compiler wasn't being compiled in an ssdb grade.
