19    Description:
20    
21    More 64-bit hacking (but still not even half-way there yet).
22    Also, some assorted improvements to the handling of 8-bit words.

29    
30    Started adding some infrastructure for supporting 64-bit int- and
31    word-types.  (Still in its very early stages.)

37    Description:
38    
39    New working version (110.50).  NEW BOOTFILES!
40    
41                 =====================
42    
43    Also:
44    
45      - Changend config/srcarchiveurl from a file just
46        containing the URL string into a file containing
47        shell script code.  The code has access to the $VERSION variable.
48      - Made corresponding changes to config/install.sh and config/unpack.
49      - Default contents of config/srcarchiveurl uses $VERSION and
50        normally does not have to be edited to reflect a version change.
51    
52      (As a result, a version change can be done by just editing
53       config/version, the rest is now automatic.)

68    Description:
69    
70    This is the HISTORY entry for two earlier commits, both concerning
71    the x86 c-calls code in MLRISC:
72    
73      - added a missing LOAD in the code that deals with struct arguments
74      - made sure the caller does not add the wrong number of bytes to the
75        stack pointer after a call of a function returning a struct
76        (the callee already pops the implicit argument which points to
77         the space reserved for the result)

93    Tag: blume-20041020-standalone-backtrace
94    Description:
95    
96    Added a mechanism for getting back-trace information from standalone
97    programs.  Here is how it works:
98    
99       1. The part of the program from which you want to get backtrace
100          information (usually the whole program) should be wrapped with
101          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
102          main program could be modified from something like
103    
104             fun main (pgm, args) = ...
105    
106         to
107    
108            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
109    
110       2. To be able to access BackTrace.monitor, you have to add
111          library $smlnj-tdp/plugins.cm to the .cm file that contains your
112          main function.
113    
114       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
115          CM might have created in the past for your project).
116    
117       4. Build the system using this command line:
118    
119             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
120                      myprog.cm MyProg.main myprog
121    
122          instead of the usual
123    
124             ml-build myprog.cm MyProg.main myprog
125    
126    I changed a library name:
127    
128       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
129    
130    New libraries:
131    
132       $smlnj-tdp/back-trace.cm
133          -- when loaded causes the back-trace plugin to be installed
134       $smlnj-tdp/coverage.cm
135          -- when loaded causes the coverage plugin to be installed

145    Eliminated group owner specs from .cm files throughout the source tree.

150    Tag: blume-20041015-coverage
151    Description:
152    
153    * Test coverage tool added!
154    * Further reorganization of tracing-, debugging-, and profiling support:
155    
156        - moved original BTImp -- now called BackTrace -- into a separate
157          library called $/trace-debug-profile.cm
158        - eliminated all mentions of BTrace from SMLofNJ.Internals
159        - only the instrumentation mechanism is now left in the compiler proper
160        - BackTrace module is a plugin which is NOT plugged in by default
161        - Coverage module is another such plugin
162    
163    To get the benefits of any of these plugin modules, the code in
164    question must be compiled with tdp instrumentation turned on.  This
165    can be done by setting SMLofNJ.Internals.TDP.mode to true.
166    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
167    
168    Plugins are selected at link time.  (Pre-compiled instrumented code
169    can be re-loaded with different plugins in effect.)  When an
170    instrumented module is linked, whatever plugins are at that time
171    enabled will come into effect for that module.
172    
173    To enable the back-trace plugin, load library $/trace-debug-profile.cm
174    and invoke BackTrace.install() (e.g., from the interactive prompt).
175    To enable the coverage plugin, load the same library and invoke
176    Coverage.install().
177    
178    Back-traces are generated automatically on uncaught exceptions and
179    when the code in question explicitly invokes BackTrace.trigger().
180    
181    Coverage (and execution frequency-) information must be queried
182    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

188    Description:
189    
190    Snapshot of a significant overhaul of how the trace/debug/profile support
191    is hooked into the system (specifically: Core and SMLofNJ.Internals).

196    Tag: blume-20041013-tdp
197    Description:
198    
199    Some rationalization of names:
200    
201       structure BTrace -> structure TDPInstrument
202       etc.
203    
204    This is is preparation of using the original back-trace
205    instrumentation for other purposes.  "TDP" stands for
206    Trace/Debug/Profile.
207    
208    The control flag controlling whether instrumentation is on or off is now
209    registered under a different name, so instead of running sml as
210    
211     sml -Cinstrument.btrace-mode=true
212    
213    one has to say
214    
215     sml -Ctdp.instrument=true

221    Description:
222    
223    Made some minor modifications to elabcore.sml to have source regions
224    be propagated more tightly -- resulting in better (i.e., smaller)
225    regions being reported in error- and debug messages.

230    Tag: blume-20041008-cmkw
231    Description:
232    
233    Fixed handling of keywords in .cm files: After seeing "is" the lexer
234    treats subsequent occurrences of "group", "library", "source", "is",
235    "*", and "-" as ordinary identifiers rather than keywords.
236    
237    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
238    is supposed to accept a tool argument called "source", but this did
239    not work because of the clash with the keyword.

245    Description:
246    
247    Assorted cleanup work:
248    
249      - got rid of intstrmap in favor of using the library's
250        hash table implementation
251      - threw out most of the pathnames stuff, as it was not used anyway
252      - simplified tokentable implementation
253      - fixed some minor spelling errors

259    Description:
260    
261    Cleaned up the absyn to reflect the invariant that HANDLE always
262    carries a FNexp as part of the type definition.  This eliminates some
263    superfluous sanity checks at runtime down the road.
264    
265    Some minor cleanup of the btrace code.

270    Tag: blume-20041001-slave
271    Description:
272    
273    Added hack to make slave mode work in the presence of the version
274    tool.  (Still, since the master does two passes over the code for
275    CMB.make, the release number gets bumped twice when slaves are
276    attached.  I don't know if this is worth fixing...)

281    Tag: blume-20040930-version
282    Description:
283    
284    * Moved the "version" magic into its own little library under
285      src/system/smlnj/internal.  This avoids expensive reconstruction of
286      a stable src/compiler/core.cm.
287    
288    * At the same time, structure CompilerVersion is now known as
289      structure SMLNJVersion.
290    
291    * Arranged for the version tool to NOT kick in when rebuilding the system
292      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
293      Also, loading the versiontool does not work when rebuilding the system
294      because CM is not properly initialized at that time.

299    Tag: blume-20040929-autoversion
300    Description:
301    
302    Implemented some CM magic to have
303        file src/compiler/TopLevel/main/version.sml
304    generated automagically.
305    The version is taken from two files: config/version and config/release.
306    The first is expected to contain a two-part version number such as 110.49.
307    The second should contain a single number, but it may be missing.
308    
309    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
310    time the version tool is loaded (which is the first time you say CMB.make),
311    then the tool will increment the value stored in config/release every
312    time CMB.make is invoked.
313    
314    The binfile format is now insensitive to anything beyond the first
315    two components of a version number, so bumping the release does not render
316    binfiles incompatible.  Auto-bumping can be used to keep track of versions
317    during development without invalidating existing binfiles.
318    
319    In any case, every CMB.make updates the date information in version.sml.
320    (This is the date that is printed in the banner.)

327    
328    Some cleanup of the controls code.

332    Date: 2004/09/27 22:08:00 CDT
333    Tag: blume-20040927-controls
334    Description:
335    
336    Added two pieces of functionality to the Controls interface:
337    
338    1.   val save'restore: 'a control -> unit -> unit
339    
340       grabs the current value of the control in stage 1 and restores it
341       in stage 2.
342    
343    2.   val set' : 'a control * 'a -> unit -> unit
344    
345       stores the given value into the control in stage 2 (i.e., delayed)
346       but does all error checking in stage 1.
347       (This is for string controls that need to do parse their argument --
348        something that might fail.  In some cases, notably in CM, one
349        already knows the intended argument but wants to delay the actual
350        assignment until a time when error recovery would be more difficult.)
351    
352    Changed the handling of controls in tool arguments to classes "sml" and
353    "lazysml":
354       - use Controls.save'restore as a more robust way of restoring the
355         old value (in particular: without having to re-parse the string)
356       - use controls to handle the "overload" keyword in the init group
357         (I believe this change actually fixes a long-standing obscure bug.)
358

361    Date: 2004/09/27 17:00:00 CDT
362    Tag: blume-20040927-lazysml
363    Description:
364    
365    Added a new tool class called "lazysml" to CM's tool chest.  The only
366    difference to "sml" is that compilation is done with Control.lazysml
367    set to true.  A source of class "lazysml" is automatically recognized
368    by a file name suffix of ".lml".
369    
370    In addition to the above feature, the original class "sml" now also
371    supports a tool argument "lazy" which has the same effect.  As a
372    result, the following three lines are equivalent:
373    
374        foo.sml : lazysml
375        foo.sml : sml (lazy)
376        foo.sml (lazy)
377    
378    The setting goes into effect both during parsing and during
379    compilation.  The original setting is restored right after parsing and
380    after compilation, respectively.
381    
382    In addition to all the above, there is also a general mechanism to set
383    ANY of the "controls" that are available at the command line via
384    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
385    apply as well. (In fact, "lazy" is implemented as a special case of
386    the general mechanism.)
387    
388    The .cm file syntax uses a new keyword tool argument called "with".
389    There are several ways of indicating the desired settings:
390    
391        foo.sml (with:parser.quotations=true)
392        foo.sml (with:(name:parser.quotations value:true))
393        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
394        foo.sml (with:(name1=value1 name2=value2 ...))
395        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
396    
397        etc.
398    
399    Another possible abbreviation is to leave out the =v or value:v part
400    if the name refers to a boolean control (in which case the value is
401    taken to be true).  Thus, one could get lazy sml also by saying:
402    
403        foo.sml (with:parser.lazy-keyword=true)
404        foo.sml (with:parser.lazy-keyword)
405        foo.sml (with:(name:parser.lazy-keyword value:true))
406        foo.sml (with:(name:parser.lazy-keyword))

471    Description:
472    
473    Bumped the heap macig number to 0x09082004 to account for the changed
474    layout of the ML frame under MacOS X.

480    Description:
481    
482       Added a patch to _arch-n-opsys to enable the Cygwin runtime.
483    The Cygwin runtime is turned on by setting the environment
484    variable SMLNJ_CYGWIN_RUNTIME to 1.

498    Description:
499    
500    Upon request by Johannes Joemann:
501    
502    - improved ML code of installer to fall back to coping when renaming
503      fails (i.e., when source and target are on different file systems);
504      the code compiles but has yet to be tested in anger
505    - removed mlrisc from list of default targets (config/targets)

522    Another bug fix from Carl Hauser:

524    diff /net/niflab/smlnj48/src/MLRISC/graphs/udgraph.sml udgraph.sml
525    > 48c48

529    > >              | rmv((e as (k,_))::es,L) = rmv(es,if k = i then L else e::L)
530    > Without this, any deletion of an edge in an undirected graph does severe
531    > violence to the graph.

553    Description:
554    
555    Bug fix from Carl Hauser:
556    
557    single_source_shortest_paths in dijkstra.sml was observed to get wrong
558    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
559    
560    The problem is that following the expression A.update(dist,s,Num.zero)
561    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

567    Description:
568    
569    Fiddled with handling of command-line options:
570    
571      * sml now quits after processing the command line
572        if -H, -S, -h<n>, or -s<n> appears as the last
573        command-line argument
574      * a new option -q terminates the session when encountered on
575        the command line; subsequent arguments will be ignored
576      * bug fixes: short (erroneous) arguments are no longer ignored
577        completely

583    Description:
584    
585      - Added minimal IBM assembly syntax support for PowerPC.
586    
587      - Cygwin: manually changed the file cygwin.def.  Some exported symbols have
588        been altered in the runtime.  We need an automatic way to keep the file
589        in sync.

606    twiddling the type of rawccall.  (See

616    get_file_time caused CM to produce files with the wrong time stamp.

624    Added NLFFI support for Win32, adapted from a patch provided by David
625    Hansel.  This is currently completely untested.  Also, the issue
