20    This is just a minor update to sync my devel branch with the main brach.

36    Description:
37    
38    I am just flushing out some minor changes that had accumulated in
39    my private branch in order to sync with the main tree.  (This is
40    mainly because I had CVS trouble when trying to merge _into_ my
41    private branch.)
42    
43    Most people should be completely unaffected by this.

49    Description:
50    
51    1.  Removed the type LabelExp and replace it by MLTree.
52    2.  Rewritten mltree-simplify with the pattern matcher tool.
53    3.  There were some bugs in alpha code generator which would break
54        64-bit code generation.
55    4.  Redo the tools to generate code with the
56    5.  The CM files in MLRISC (and in src/system/smlnj/MLRISC)
57        are now generated by perl scripts.

63    Description:
64    
65    The RCC stuff now seems to work (but only on the x86).
66    This required hacking of the c-calls interface (and -implementation) in
67    MLRISC.
68    
69    Normal compiler users should be unaffected.

75    Description:
76    
77    This is a fairly big patch, flushing out a large number of pending
78    changes that I made to my development copy over the last couple of days.
79    
80    Of practical relevance at this moment is a workaround for a pickling
81    bug that Allen ran into the other day.  The cause of the bug itself is
82    still unknown and it might be hard to fix it properly, but the
83    workaround has some merits of its own (namely somewhat reducing pickling
84    overhead for certain libraries).  Therefore, I think this solution should
85    be satisfactory at this time.
86    
87    The rest of the changes (i.e., the vast majority) has to do with my
88    ongoing efforts of providing direct support for C function calls from
89    ML.  At the moment there is a new primop "RAW_CCALL", typing magic
90    in types/cproto.sml (invoked from FLINT/trans/translate.sml), a new
91    case in the FLINT CPS datatype (RCC), changes to cps/convert.sml to
92    translate uses of RAW_CCALL into RCC, and changes to mlriscGen.sml to
93    handle RCC.
94    
95    The last part (the changes to mlriscGen.sml) are still known to be
96    wrong on the x86 and not implemented on all other architectures.  But
97    the infrastructure is in place. I had to change a few functor
98    signatures in the backend to be able to route the CCalls interface
99    from MLRISC there, and I had to specialize the mltree type (on the
100    x86) to include the necessary extensions. (The extensions themselves
101    were already there and redy to go in MLRISC/x86).
102    
103    Everything should be very happy as soon as someone helps me with
104    mlriscGen.sml...
105    
106    In any case, nothing of this should matter to anyone as long as the
107    new primop is not being used (which is going to be the case unless you
108    find it where I hid it :). The rest of the compiler is completely
109    unaffected.

114    Tag: blume-20010105-primops
115    Description:
116    
117    Added some experimental support for work that I am doing right now.
118    These changes mostly concern added primops, but there is also a new
119    experimental C library in the runtime system (but currently not enabled
120    anywhere except on Linux/X86).
121    
122    In the course of adding primops (and playing with them), I discovered that
123    Zhong's INL_PRIM hack (no type info for certain primops) was, in fact, badly
124    broken.  (Zhong was very right he labeled this stuff as "major gross hack".)
125    To recover, I made type information in INL_PRIM mandatory and changed
126    prim.sml as well as built-in.sml accordingly.  The InLine structure now
127    has complete, correct type information (i.e., no bottom types).
128    
129    Since all these changes mean that we need new binfiles, I also bumped the
130    version number to 110.32.1.

136    Description:
137    
138    Added proxy libraries for MLRISC and let MLRISC libraries refer
139    to each other using path anchors.  (See CM manual for explanation.)
140    
141    Updated CM documentation.
142    
143    Fixed some bugs in CM.
144    
145    Implemented "proxy" libraries (= syntactic sugar for CM).
146    
147    Added "-quiet" option to makeml and changed runtime system accordingly.
148    
149    Added cleanup handler for exportML to reset timers and compiler stats.

191    Probably most important: CM no longer silently swallows all exceptions
192    in the compiler.
193    Plus: some other minor CM changes.  For example, CM now reports some
194    sizes for generated binfiles (code, data, envpickle, lambdapickle).

245    Tag:  leunga-20001207-cell-monster-hack
246    Description:
247    
248    Major MLRISC internal changes.  Affect all clients.
249    Summary:
250    
251    1.  Type CELLS.cell = int is now replaced by a datatype.
252        As a result, the old regmap is now gone.  Almost all interfaces
253        in MLRISC change as a consequence.
254    
255    2.  A new brand version of machine description tool (v3.0) that generates
256        modules expecting the new interface.  The old version is removed.
257    
258    3.  The RA interface has been further abstracted into two new functors.
259        RISC_RA and X86RA.  These functors have much simpler interfaces.
260        [See also directory MLRISC/demo.]
261    
262    4.  Some other new source->source code generation tools are available:
263    
264        a. MLRISC/Tools/RewriteGen -- generate rewriters from rules.
265        b. MLRISC/Tools/WhereGen -- expands conditional pattern matching rules.
266           I use this tool to generate the peephole optimizers---with the new
267           cell type changes, peephole rules are becoming difficult to write
268           without conditional pattern matching.
269    
270    5.  More Intmap -> IntHashTable change.  Previous changes by Matthias didn't
271        cover the entire MLRISC source tree so many things broke.
272    
273    6.  CM files have been moved to the subdirectory MLRISC/cm.
274        They are moved because there are a lot of them and they clutter up the
275        root dir.
276    
277    7.  More detailed documentation to come...
278    
279        NOTE: To rebuild from 110.30 (ftp distribution), you'll have to do
280        a makeml -rebuild first.  This is because of other other
281        changes that Matthias has made (see below).

296    Description:
297    
298    Drastically improved link traversal code for the case that the dynamic
299    value was already loaded at bootstrap time.  As a result, CM and CMB
300    now both load blazingly fast -- even on a very slow machine.  Also,
301    memory consumption has been further reduced by this.
302    
303    Warning: The format of the PIDMAP file has changed.  THerefore, to
304    bootstrap you have to do this:
305    
306    1. Run CMB.make
307    2. Make a symbolic link for the boot directory:
308         ln -s sml.boot.ARCH-OS xxx
309    3. "Rebuild" the boot directory:
310         ./makeml -boot xxx -rebuild sml ; rm xxx
311    4. Boot normally:
312          ./makeml

341    2. Made pickle-lib.cm
342    3. Eliminated all uses of intset.sml (from comp-lib.cm)
343    4. Replaced all uses of intmap.{sig,sml} (from comp-lib.cm) with
344       equivalent constructs from smlnj-lib.cm (INtHashTable).
345    5. Point 4. also goes for those uses of intmap.* in MLRISC.
346       Duplicated intmap modules thrown out.
347    6. Hunted down all duplicated SCC code and replaced it with
348       equivalent stuff (GraphSCCFn from smlnj-lib.cm).
349    7. Rewrote Feedback module.
350    8. Moved sortedlist.sml into viscomp-lib.cm.  Eventually it
351       should be thrown out and equivalent modules from smlnj-lib.cm
352       should be used (IntRedBlackSet, IntListSet, ...).
353    
354    Confirmed that compiler compiles to fixpoint.

359    Tag: leunga-20001110-new-x86-fp
360    
361    A new x86 floating point code generator has been added.
362    By default this is turned off.  To turn this on, do:
363    
364        CM.autoload "$smlnj/compiler.cm";
365        Compiler.Control.MLRISC.getFlag "x86-fast-fp" := true;
366    
367    Changes:
368    
369    1.  Changed FTAN to FPTAN so that the assembly output is correct.
370    2.  Changed the extension callback for FTANGENT to generate:
371    
372              fptan
373              fstp  %st(0)
374        instead of
375              fptan
376              fstpl ftempmem
377    
378    3.  Numerous assembly fixes for x86.
379    
380    5.  Cleaned up the machine code output module x86/x86MC.sml and added
381        support for a whole bunch of instructions and addressing modes:
382    
383          fadd/fsub/fsubr/fmul/fdiv/fdivr  %st, %st(n)
384          faddp/fsubp/fsubrp/fmulp/fdivp/fdivrp  %st, %st(n)
385          fadd/fsub/fsubr/fmul/fdiv/fdivr  %st(n), %st
386          fiadd/fisub/fisubr/fimul/fidiv/fidivr mem
387          fxch %st(n)
388          fld %st(n)
389          fst %st(n)
390          fst mem
391          fstp %st(n)
392          fucom %st(n)
393          fucomp %st(n)
394    
395        All these are now generated when the fast fp mode is turned on.
396    
397    6.  Removed the dedicated registers %st(0), ..., %st(7) from X86CpsRegs

507    
508      Moby, C--, SSA, x86, machine descriptions etc.  Should only affect C--
509    and Mobdy.
510    
511    1.  x86
512    
513       a.  Fixes to peephole module by John and Dan.
514       b.  Assembly fix to SETcc by Allen.
515       c.  Fix to c-call by John.
516       d.  Fix to spilling by John.  (This one deals with the missing FSTPT case)
517       e.  Instruction selection optimization to SETcc as suggested by John.
518    
519           For example,
520    
521            MV(32, x, COND(32, CMP(32, LT, a, b), LI 1, LI 0))
522    
523           should generate:
524    
525            MOVL a, x
526            SUBL b, x
527            SHRL 31, x
528    
529    2.  IR stuff
530    
531         A bunch of new DJ-graph related algorithms added.  These
532         speed up SSA construction.
533    
534    3.  SSA + Scheduling
535    
536         Added code for SSA and scheduling to the repository

552    Description:
553    
554    !!!! WARNING !!!!
555    You must recompile the runtime system!
556    !!!! WARNING !!!!
557    
558    This is basically another round of script-enhancements:
559    
560    1. sml, ml-build, and ml-makedepend accept options -D and -U to define
561       and undefine CM preprocessor symbols.
562    
563    2. ml-build avoids generating a new heap image if it finds that the
564       existing one is still ok.  (The condition is that no ML file had to
565       be recompiled and all ML files are found to be older that the heap
566       file.)
567    
568       To make this work smoothly, I also hacked the runtime system as
569       well as SMLofNJ.SysInfo to get access to the heap image suffix
570       (.sparc-solaris, ...) that is currently being used.
571    
572       Moreover, the signature of CM.mk_standalone has changed.  See the
573       CM manual.
574    
575    3. ml-makedepend accepts additional options -n, -a, and -o.  (See the
576       CM manual for details.)
577    
578    4. More CM manual updates:
579        - all of the above has been documented.
580        - there is now a section describing the (CM-related) command line
581          arguments that are accepted by the "sml" command

587    Description:
588    
589    Added a script called ml-makedepend.  This can be used in makefiles
590    for Unix' make in a way very similar to the "makedepend" command for
591    C.
592    
593    The script internally uses function CM.sources.
594    
595    Synopsis:
596    
597        ml-makedepend [-f makefile] cmfile targetname
598    
599    The default for the makefile is "makefile" (or "Makefile" should
600    "makefile" not exist).
601    
602    ml-makedepend adds a cmfile/targetname-specific section to this
603    makefile (after removing the previous version of this section).  The
604    section contains a single dependency specification with targetname on
605    the LHS (targetname is an arbitrary name), and a list of files derived
606    from the cmfile on the RHS.  Some of the files on the RHS are
607    ARCH/OPSYS-specific.  Therefore, ml-makedepend inserts references to
608    "make" variables $(ARCH) and $(OPSYS) in place of the corresponding
609    path names.  The makefile writer is responsible for making sure that
610    these variables have correct at the time "make" is invoked.

660    Description:
661    
662    1. Improvements to CM manual.
663    2. SMLofNJ.Internals.BTrace.trigger reinstated as an alternative way
664       of getting a back-trace.  The function, when called, raises an
665       internal exception which explicitly carries the full back-trace history,
666       so it is unaffected by any intervening handle-raise pairs ("trivial"
667       or not).  The interactive loop will print that history once it arrives
668       at top level.
669       Short of having all exceptions implicitly carry the full history, the
670       recommended way of using this facility is:
671         - compile your program with instrumentation "on"
672         - run it, when it raises an exception, look at the history
673         - if the history is "cut off" because of some handler, go and modify
674           your program so that it explicitly calls BTrace.trigger
675         - recompile (still instrumented), and rerun; look at the full history
