19    Description:
20    
21    Started adding some infrastructure for supporting 64-bit int- and
22    word-types.  (Still in its very early stages.)

28    Description:
29    
30    New working version (110.50).  NEW BOOTFILES!
31    
32                 =====================
33    
34    Also:
35    
36      - Changend config/srcarchiveurl from a file just
37        containing the URL string into a file containing
38        shell script code.  The code has access to the $VERSION variable.
39      - Made corresponding changes to config/install.sh and config/unpack.
40      - Default contents of config/srcarchiveurl uses $VERSION and
41        normally does not have to be edited to reflect a version change.
42    
43      (As a result, a version change can be done by just editing
44       config/version, the rest is now automatic.)

59    Description:
60    
61    This is the HISTORY entry for two earlier commits, both concerning
62    the x86 c-calls code in MLRISC:
63    
64      - added a missing LOAD in the code that deals with struct arguments
65      - made sure the caller does not add the wrong number of bytes to the
66        stack pointer after a call of a function returning a struct
67        (the callee already pops the implicit argument which points to
68         the space reserved for the result)

84    Tag: blume-20041020-standalone-backtrace
85    Description:
86    
87    Added a mechanism for getting back-trace information from standalone
88    programs.  Here is how it works:
89    
90       1. The part of the program from which you want to get backtrace
91          information (usually the whole program) should be wrapped with
92          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
93          main program could be modified from something like
94    
95             fun main (pgm, args) = ...
96    
97         to
98    
99            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
100    
101       2. To be able to access BackTrace.monitor, you have to add
102          library $smlnj-tdp/plugins.cm to the .cm file that contains your
103          main function.
104    
105       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
106          CM might have created in the past for your project).
107    
108       4. Build the system using this command line:
109    
110             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
111                      myprog.cm MyProg.main myprog
112    
113          instead of the usual
114    
115             ml-build myprog.cm MyProg.main myprog
116    
117    I changed a library name:
118    
119       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
120    
121    New libraries:
122    
123       $smlnj-tdp/back-trace.cm
124          -- when loaded causes the back-trace plugin to be installed
125       $smlnj-tdp/coverage.cm
126          -- when loaded causes the coverage plugin to be installed

135    
136    Eliminated group owner specs from .cm files throughout the source tree.

141    Tag: blume-20041015-coverage
142    Description:
143    
144    * Test coverage tool added!
145    * Further reorganization of tracing-, debugging-, and profiling support:
146    
147        - moved original BTImp -- now called BackTrace -- into a separate
148          library called $/trace-debug-profile.cm
149        - eliminated all mentions of BTrace from SMLofNJ.Internals
150        - only the instrumentation mechanism is now left in the compiler proper
151        - BackTrace module is a plugin which is NOT plugged in by default
152        - Coverage module is another such plugin
153    
154    To get the benefits of any of these plugin modules, the code in
155    question must be compiled with tdp instrumentation turned on.  This
156    can be done by setting SMLofNJ.Internals.TDP.mode to true.
157    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
158    
159    Plugins are selected at link time.  (Pre-compiled instrumented code
160    can be re-loaded with different plugins in effect.)  When an
161    instrumented module is linked, whatever plugins are at that time
162    enabled will come into effect for that module.
163    
164    To enable the back-trace plugin, load library $/trace-debug-profile.cm
165    and invoke BackTrace.install() (e.g., from the interactive prompt).
166    To enable the coverage plugin, load the same library and invoke
167    Coverage.install().
168    
169    Back-traces are generated automatically on uncaught exceptions and
170    when the code in question explicitly invokes BackTrace.trigger().
171    
172    Coverage (and execution frequency-) information must be queried
173    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

179    Description:
180    
181    Snapshot of a significant overhaul of how the trace/debug/profile support
182    is hooked into the system (specifically: Core and SMLofNJ.Internals).

187    Tag: blume-20041013-tdp
188    Description:
189    
190    Some rationalization of names:
191    
192       structure BTrace -> structure TDPInstrument
193       etc.
194    
195    This is is preparation of using the original back-trace
196    instrumentation for other purposes.  "TDP" stands for
197    Trace/Debug/Profile.
198    
199    The control flag controlling whether instrumentation is on or off is now
200    registered under a different name, so instead of running sml as
201    
202     sml -Cinstrument.btrace-mode=true
203    
204    one has to say
205    
206     sml -Ctdp.instrument=true

212    Description:
213    
214    Made some minor modifications to elabcore.sml to have source regions
215    be propagated more tightly -- resulting in better (i.e., smaller)
216    regions being reported in error- and debug messages.

221    Tag: blume-20041008-cmkw
222    Description:
223    
224    Fixed handling of keywords in .cm files: After seeing "is" the lexer
225    treats subsequent occurrences of "group", "library", "source", "is",
226    "*", and "-" as ordinary identifiers rather than keywords.
227    
228    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
229    is supposed to accept a tool argument called "source", but this did
230    not work because of the clash with the keyword.

236    Description:
237    
238    Assorted cleanup work:
239    
240      - got rid of intstrmap in favor of using the library's
241        hash table implementation
242      - threw out most of the pathnames stuff, as it was not used anyway
243      - simplified tokentable implementation
244      - fixed some minor spelling errors

250    Description:
251    
252    Cleaned up the absyn to reflect the invariant that HANDLE always
253    carries a FNexp as part of the type definition.  This eliminates some
254    superfluous sanity checks at runtime down the road.
255    
256    Some minor cleanup of the btrace code.

262    Description:
263    
264    Added hack to make slave mode work in the presence of the version
265    tool.  (Still, since the master does two passes over the code for
266    CMB.make, the release number gets bumped twice when slaves are
267    attached.  I don't know if this is worth fixing...)

272    Tag: blume-20040930-version
273    Description:
274    
275    * Moved the "version" magic into its own little library under
276      src/system/smlnj/internal.  This avoids expensive reconstruction of
277      a stable src/compiler/core.cm.
278    
279    * At the same time, structure CompilerVersion is now known as
280      structure SMLNJVersion.
281    
282    * Arranged for the version tool to NOT kick in when rebuilding the system
283      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
284      Also, loading the versiontool does not work when rebuilding the system
285      because CM is not properly initialized at that time.

290    Tag: blume-20040929-autoversion
291    Description:
292    
293    Implemented some CM magic to have
294        file src/compiler/TopLevel/main/version.sml
295    generated automagically.
296    The version is taken from two files: config/version and config/release.
297    The first is expected to contain a two-part version number such as 110.49.
298    The second should contain a single number, but it may be missing.
299    
300    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
301    time the version tool is loaded (which is the first time you say CMB.make),
302    then the tool will increment the value stored in config/release every
303    time CMB.make is invoked.
304    
305    The binfile format is now insensitive to anything beyond the first
306    two components of a version number, so bumping the release does not render
307    binfiles incompatible.  Auto-bumping can be used to keep track of versions
308    during development without invalidating existing binfiles.
309    
310    In any case, every CMB.make updates the date information in version.sml.
311    (This is the date that is printed in the banner.)

318    
319    Some cleanup of the controls code.

324    Tag: blume-20040927-controls
325    Description:
326    
327    Added two pieces of functionality to the Controls interface:
328    
329    1.   val save'restore: 'a control -> unit -> unit
330    
331       grabs the current value of the control in stage 1 and restores it
332       in stage 2.
333    
334    2.   val set' : 'a control * 'a -> unit -> unit
335    
336       stores the given value into the control in stage 2 (i.e., delayed)
337       but does all error checking in stage 1.
338       (This is for string controls that need to do parse their argument --
339        something that might fail.  In some cases, notably in CM, one
340        already knows the intended argument but wants to delay the actual
341        assignment until a time when error recovery would be more difficult.)
342    
343    Changed the handling of controls in tool arguments to classes "sml" and
344    "lazysml":
345       - use Controls.save'restore as a more robust way of restoring the
346         old value (in particular: without having to re-parse the string)
347       - use controls to handle the "overload" keyword in the init group
348         (I believe this change actually fixes a long-standing obscure bug.)
349

352    Date: 2004/09/27 17:00:00 CDT
353    Tag: blume-20040927-lazysml
354    Description:
355    
356    Added a new tool class called "lazysml" to CM's tool chest.  The only
357    difference to "sml" is that compilation is done with Control.lazysml
358    set to true.  A source of class "lazysml" is automatically recognized
359    by a file name suffix of ".lml".
360    
361    In addition to the above feature, the original class "sml" now also
362    supports a tool argument "lazy" which has the same effect.  As a
363    result, the following three lines are equivalent:
364    
365        foo.sml : lazysml
366        foo.sml : sml (lazy)
367        foo.sml (lazy)
368    
369    The setting goes into effect both during parsing and during
370    compilation.  The original setting is restored right after parsing and
371    after compilation, respectively.
372    
373    In addition to all the above, there is also a general mechanism to set
374    ANY of the "controls" that are available at the command line via
375    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
376    apply as well. (In fact, "lazy" is implemented as a special case of
377    the general mechanism.)
378    
379    The .cm file syntax uses a new keyword tool argument called "with".
380    There are several ways of indicating the desired settings:
381    
382        foo.sml (with:parser.quotations=true)
383        foo.sml (with:(name:parser.quotations value:true))
384        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
385        foo.sml (with:(name1=value1 name2=value2 ...))
386        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
387    
388        etc.
389    
390    Another possible abbreviation is to leave out the =v or value:v part
391    if the name refers to a boolean control (in which case the value is
392    taken to be true).  Thus, one could get lazy sml also by saying:
393    
394        foo.sml (with:parser.lazy-keyword=true)
395        foo.sml (with:parser.lazy-keyword)
396        foo.sml (with:(name:parser.lazy-keyword value:true))
397        foo.sml (with:(name:parser.lazy-keyword))

490    
491    Upon request by Johannes Joemann:
492    
493    - improved ML code of installer to fall back to coping when renaming
494      fails (i.e., when source and target are on different file systems);
495      the code compiles but has yet to be tested in anger
496    - removed mlrisc from list of default targets (config/targets)
