18    Description:
19    
20    New URL for boot files (because the 110.29 files on the BL server do
21    now work correctly with my updated install scripts for yacc and lex).

35    
36      Moby, C--, SSA, x86, machine descriptions etc.  Should only affect C--
37    and Mobdy.
38    
39    1.  x86
40    
41       a.  Fixes to peephole module by John and Dan.
42       b.  Assembly fix to SETcc by Allen.
43       c.  Fix to c-call by John.
44       d.  Fix to spilling by John.  (This one deals with the missing FSTPT case)
45       e.  Instruction selection optimization to SETcc as suggested by John.
46    
47           For example,
48    
49            MV(32, x, COND(32, CMP(32, LT, a, b), LI 1, LI 0))
50    
51           should generate:
52    
53            MOVL a, x
54            SUBL b, x
55            SHRL 31, x
56    
57    2.  IR stuff
58    
59         A bunch of new DJ-graph related algorithms added.  These
60         speed up SSA construction.
61    
62    3.  SSA + Scheduling
63    
64         Added code for SSA and scheduling to the repository

79    Tag: blume-20000727-scripts
80    Description:
81    
82    !!!! WARNING !!!!
83    You must recompile the runtime system!
84    !!!! WARNING !!!!
85    
86    This is basically another round of script-enhancements:
87    
88    1. sml, ml-build, and ml-makedepend accept options -D and -U to define
89       and undefine CM preprocessor symbols.
90    
91    2. ml-build avoids generating a new heap image if it finds that the
92       existing one is still ok.  (The condition is that no ML file had to
93       be recompiled and all ML files are found to be older that the heap
94       file.)
95    
96       To make this work smoothly, I also hacked the runtime system as
97       well as SMLofNJ.SysInfo to get access to the heap image suffix
98       (.sparc-solaris, ...) that is currently being used.
99    
100       Moreover, the signature of CM.mk_standalone has changed.  See the
101       CM manual.
102    
103    3. ml-makedepend accepts additional options -n, -a, and -o.  (See the
104       CM manual for details.)
105    
106    4. More CM manual updates:
107        - all of the above has been documented.
108        - there is now a section describing the (CM-related) command line
109          arguments that are accepted by the "sml" command

114    Tag: blume-20000725-makedepend
115    Description:
116    
117    Added a script called ml-makedepend.  This can be used in makefiles
118    for Unix' make in a way very similar to the "makedepend" command for
119    C.
120    
121    The script internally uses function CM.sources.
122    
123    Synopsis:
124    
125        ml-makedepend [-f makefile] cmfile targetname
126    
127    The default for the makefile is "makefile" (or "Makefile" should
128    "makefile" not exist).
129    
130    ml-makedepend adds a cmfile/targetname-specific section to this
131    makefile (after removing the previous version of this section).  The
132    section contains a single dependency specification with targetname on
133    the LHS (targetname is an arbitrary name), and a list of files derived
134    from the cmfile on the RHS.  Some of the files on the RHS are
135    ARCH/OPSYS-specific.  Therefore, ml-makedepend inserts references to
136    "make" variables $(ARCH) and $(OPSYS) in place of the corresponding
137    path names.  The makefile writer is responsible for making sure that
138    these variables have correct at the time "make" is invoked.

187    Tag: blume-20000704-trigger
188    Description:
189    
190    1. Improvements to CM manual.
191    2. SMLofNJ.Internals.BTrace.trigger reinstated as an alternative way
192       of getting a back-trace.  The function, when called, raises an
193       internal exception which explicitly carries the full back-trace history,
194       so it is unaffected by any intervening handle-raise pairs ("trivial"
195       or not).  The interactive loop will print that history once it arrives
196       at top level.
197       Short of having all exceptions implicitly carry the full history, the
198       recommended way of using this facility is:
199         - compile your program with instrumentation "on"
200         - run it, when it raises an exception, look at the history
201         - if the history is "cut off" because of some handler, go and modify
202           your program so that it explicitly calls BTrace.trigger
203         - recompile (still instrumented), and rerun; look at the full history

217    Description:
218    
219    Changes:
220    
221    1. Class "mlyacc" now takes separate arguments to pass options to
222       generated .sml- and .sig-files independently.
223    2. Corresponding CM manual updates.
224    3. BTrace module now also reports call sites.  (However, for loop clusters
225       it only shows from where the cluster was entered.)  There are associated
226       modifications to core.sml, internals.{sig,sml}, btrace.sml, and btimp.sml.

231    Tag: blume-20000627-noweb
232    Description:
233    
234    Changes:
235    
236     1. Implemented "subdir" and "witness" options for noweb tool.
237        This caused some slight internal changes in CM's tool implementation.
238     2. Fixed bug in "tool plugin" mechanism.  This is essentially cleaning
239        some remaining issues from earlier path anchor changes.
240     3. Updated CM manual accordingly.
241    
242     4. Changed implementation of back-tracing so that I now consider it
243        ready for prime-time.
244    
245        In particular, you don't have to explicitly trigger the back-trace
246        anymore.  Instead, if you are running BTrace-instrumented code and
247        there is an uncaught exception (regardless of whether or not it was
248        raised in instrumented code), the top-level evalloop will print
249        the back-trace.
250    
251        Features:
252    
253          - Instrumented and uninstrumented code work together seemlessly.
254            (Of course, uninstrumented code is never mentioned in actual
255             back-traces.)
256    
257          - Asymptotic time- and space-complexity of instrumented code is
258            equal to that of uninstrumented code.  (This means that
259            tail-recursion is preserved by the instrumentation phase.)
260    
261          - Modules whose code has been instrumented in different sessions
262            work together without problem.
263    
264          - There is no penalty whatsoever on uninstrumented code.
265    
266          - There is no penalty on "raise" expressions, even in
267            instrumented code.
268    
269        A potential bug (or perhaps it is a feature, too):
270    
271          A back-trace reaches no further than the outermost instrumented
272          non-trivial "raise".  Here, a "trivial" raise is one that is the
273          sole RHS of a "handle" rule.  Thus, back-traces reach trough
274    
275               <exp> handle e => raise e
276    
277          and even
278    
279               <exp> handle Foo => raise Bar
280    
281          and, of course, through
282    
283               <exp> handle Foo => ...
284    
285         if the exception was not Foo.
286    
287         Back-traces always reach right through any un-instrumented code
288         including any of its "handle" expressions, trivial or not.
289    
290       To try this out, do the following:
291    
292         - Erase all existing binfiles for your program.
293           (You may keep binfiles for those modules where you think you
294            definitely don't need back-tracing.)
295         - Turn on back-trace instrumentation:
296              SMLofNJ.Internals.BTrace.mode (SOME true);
297         - Recompile your program.  (I.e., run "CM.make" or "use".)
298         - You may now turn instrumentation off again (if you want):
299              SMLofNJ.Internals.BTrace.mode (SOME false);
300         - Run your program as usual.  If it raises an exception that
301           reaches the interactive toplevel, then a back-trace will
302           automatically be printed.  After that, the toplevel loop
303           will print the exception history as usual.

308    Tag: blume-20000626-setup
309    Description:
310    
311    CM: - setup-parameter to "sml" added; this can be used to run arbitrary
312          ML code before and after compiling a file (e.g., to set compiler
313          flags)
314    
315    Compiler: - improved btrace API (in core.sml, internals.{sig,sml})
316              - associated changes to btrace.sml (BTrace instrumentation pass)
317              - cleaner implementation of btimp.sml (BTrace tracing and report
318                module)
319    
320    CM manual: * new path encoding documented
321               * description of setup-parameter to "sml" added
322    
323    The biggest user-visible change to back-tracing is that it is no
324    longer necessary to compile all traced modules within the same
325    session.  (This was a real limitation.)
