33    Description:
34    
35    A new noweb tool has been added.  The existing system is entirely
36    unaffected by this, but some CM users have asked for renewed noweb
37    support.  Everything is documented in the CM manual.
38    
39    New (plugin) libraries:

65    Tag: blume-20000430-versions
66    Description:
67    
68    1. CM version numbering added.  This is an implementation of Lal's
69       proposal for adding version numbers and version checking to .cm
70       files.  Lal said that his proposal was just that -- a proposal.
71       For the time being I went ahead and implemented it so that people
72       can comment on it.  Everything is completely backward-compatible
73       (except for the stable library format, i.e., new bootfiles!).
74    
75       As usual, see the CM manual for details.
76    
77    2. An alternative syntax for anchored paths has been implemented.
78       Dave has recently voiced the same concerns that I had when I did
79       this, so there should be some support.  My take is that eventually
80       I will let support for the current syntax (where anchors are
81       "implicit") fade out in favor of the new, explicit syntax.
82       In order to be backward-compatible, both old and new syntax are
83       currently supported.
84    
85       Again, see the CM manual for details.
86    
87    3. Parallel make is trying to be slightly smarter:  When the master
88       process finds a "bottleneck", i.e., when there is only one
89       compilation unit that can be compiled and everybody else is
90       waiting on it, then it will simply compile it directly instead
91       of clumsily telling one of the slaves to do it.
92    
93    4. Support for "unsharing" added.  This is necessary in order to be
94       able to have two different versions of the same library running
95       at the same time (e.g., for trying out a new MLRISC while still
96       having the old MLRISC linked into the current compiler, etc.)
97       See the CM manual.
98    
99    5. Simple "makedepend" functionality added for generating Makefile
100       dependency information.  (This is rather crude at the moment.
101       Expect some changes here in the future.)
102    
103    6. ".fun" added as a recognized suffix for ML files. Also documented
104       explicitly in the manual that the fallback behavior (unknown suffix
105       -> ML file) is not an official feature!
106    
107    7. Small changes to the pickler for stable libraries.
108    
109    8. Several internal changes to CM (for cleanup/improvement).
110    
111    
112    !!!! NEW BINFILES !!!!

117    Tag: blume-20000428-pathconfig
118    Description:
119    
120    1. I changed config/install.sh to remove duplicate entries from the
121       lib/pathconfig file at the end.  Moreover, the final version of
122       lib/pathconfig is sorted alphabetically.  The same (sorting) is done
123       in src/system/installml.
124    
125    2. The config/install.sh script now consistently uses relative
126       pathnames in lib/pathconfig whenever the anchor is in the lib
127       directory.  (So far this was true for the libraries that come
128       pre-compiled and bundled as part of the bootfiles but not for
129       libraries that are compiled by the script itself.)

167    Tag: leunga-20000420-ssa-c---stuff
168    Description:
169    
170      This update synchronizes my repository with Yale's.  Most of these
171    changes, however, do not affect SML/NJ at all (the RA is an exception).
172    
173    1. Register Allocator
174    
175       a. An improvement in the interference graph construction:
176          Given a copy
177    
178                s <- t
179    
180          no interference edge between s and t is added for this definition of s.
181    
182       b. I've added two new spill heuristic modules that Fermin and I developed
183          (in the new library RA.cm). These are unused in SML/NJ but maybe
184          useful for others (Moby?)
185    
186    2. X86
187    
188       a. Various fixes in the backend provided by Fermin [C--] and Lal.
189    
190    3. Alpha
191    
192       a. Added the BSR instruction and code generation that goes with it [C--]
193       b. Other fixes too numerous to recount provided by Fermin [C--]
194    
195    4. Regmaps
196    
197       a. The regmaps are not initialized with the identity physical bindings
198          at creation time.  This is unneeded.
199    
200    5. MLRISC Optimizations
201    
202       a. The DJ-Graph module can now compute the iterated dominance frontiers
203          intersects with liveness incrementally in linear time! Woohoo!
204          This is now used in my new SSA construction algorithm.
205    
206       b. THe branch reorganization module is now smarter about linear chains of
207          basic blocks.

286    Description:
287    
288    1.  Fixed a problem in X86 assembly.
289    
290        Things like
291    
292           jmp %eax
293           jmp (%eax)
294    
295        should be output as
296    
297           jmp *%eax
298           jmp *(%eax)

300    2.  Assembly output
301    
302          Added a new flag
303    
304              "asm-indent-copies" (default to false)
305    
306          When this flag is on, parallel copies will be indented an extra level.

311    Tag: leunga-20000404-C--Moby
312    Description:
313    
314        All of these fixes are related to C--, Moby, and my own optimization
315        stuff; so they shouldn't affect SML/NJ.
316    
317    1.  X86
318    
319        Various fixes related floating point, and extensions.
320    
321    2.  Alpha
322    
323        Some extra patterns related to loads with signed/zero extension
324        provided by Fermin.
325    
326    3.  Assembly
327    
328        When generating assemby, resolve the value of client defined constants,
329        instead of generating symbolic values.  This is controlled by the
330        new flag "asm-resolve-constants", which is default to true.
331    
332    4.  Machine Descriptions
333    
334        a. The precedence parser was slightly broken when parsing infixr symbols.
335        b. The type generalizing code had the bound variables reversed, resulting
336           in a problem during arity raising.
337        c. Various fixes in machine descriptions.

343    Description:
344    
345    I eliminated coreEnv from compInfo.  Access to the "Core" structure is
346    now done via the ordinary static environment that is context to each
347    compilation unit.
348    
349    To this end, I arranged that instead of "structure Core" as "structure
350    _Core" is bound in the pervasive environment.  Core access is done via
351    _Core (which can never be accidentially rebound because _Core is not a
352    legal surface-syntax symbol).
353    
354    The current solution is much cleaner because the core environment is
355    now simply part of the pervasive environment which is part of every
356    compilation unit's context anyway.  In particular, this eliminates all
357    special-case handling that was necessary until now in order to deal
358    with dynamic and symbolic parts of the core environment.
359    
360    Remaining hackery (to bind the "magic" symbol _Core) is localized in the
361    compilation mananger's bootstrap compiler (actually: in the "init group"
362    handling).  See the comments in src/system/smlnj/init/init.cmi for
363    more details.
364    
365    I also tried to track down all mentions of "Core" (as string argument
366    to Symbol.strSymbol) in the compiler and replaced them with a
367    reference to the new CoreSym.coreSym.  Seems cleaner since the actual
368    name appears in one place only.
369    
370    Binfile and bootfile format have not changed, but the switchover from
371    the old "init.cmi" to the new one is a bit tricky, so I supplied new
372    bootfiles anyway.

388    Description:
389    
390    This update contains a rewritten (and hopefully more correct) module
391    for extracting aliasing information from CPS.
392    
393       To turn on this feature:
394    
395            Compiler.Control.CG.memDisambiguate := true
396    
397       To pretty print the region information with assembly
398    
399           Compiler.Control.MLRISC.getFlag "asm-show-region" := true;
400    
401       To control how many levels of aliasing information are printed, use:
402    
403           Compiler.Control.MLRISC.getInt "points-to-show-level" := n
404    
405       The default of n is 3.

425    Description:
426    
427    This update contains:
428    
429    1. A small change to CM's handling of stable libraries:
430       CM now maintains one "global" modmap that is used for all stable
431       libraries.  The use of such a global modmap maximizes sharing and
432       minimizes the need for re-traversing parts of environments during
433       modmap construction.  (However, this has minor impact since modmap
434       construction seems to account for just one percent or less of total
435       compile time.)
436    
437    2. I added a "genmap" phase to the statistics.  This is where I got the
438       "one percent" number (see above).
439    
440    3. CM's new tool parameter mechanism just became _even_ better. :)
441       - The parser understands named parameters and recursive options.
442       - The "make" and "shell" tools use these new features.
443         (This makes it a lot easier to cascade these tools.)
444       - There is a small syntax change: named parameters use a
445    
446           <name> : ( <option> ... )            or
447           <name> : <string>
448    
449         syntax.  Previously, named parameters were implemented in an
450         ad-hoc fashion by each tool individually (by parsing strings)
451         and had the form
452    
453           <name>=<string>
454    
455       See the CM manual for a full description of these issues.

462    
463    !!!!! WARNING !!!!!!
464    !!  New binfiles  !!
465    !!!!!!!!!!!!!!!!!!!!
466    
467    This update contains:
468    
469    1. Moderate changes to CM:
470    
471       - Changes to CM's tools mechanism.  In particular, it is now possible
472       to have tools that accept additional "command line" parameters
473       (specified in the .cm file at each instance where the tool's class is
474       used).
475    
476       This was done to accomodate the new "make" and "shell" tools which
477       facilitate fairly seemless hookup to portions of code managed using
478       Makefiles or Shell scripts.
479    
480       There are no classes "shared" or "private" anymore.  Instead, the
481       sharing annotation is now a parameter to the "sml" class.
482    
483       There is a bit of generic machinery for implementing one's own
484       tools that accept command-line parameters.  However, I am not yet fully
485       satisfied with that part, so expect changes here in the future.
486    
487       All existing tools are described in the CM manual.
488    
489       - Slightly better error handling.  (CM now surpresses many followup
490       error messages that tended to be more annoying than helpful.)
491    
492    2. Major changes to the compiler's static environment data structures.
493    
494       - no CMStaticEnv anymore.
495            - no CMEnv, no "BareEnvironment" (actually, _only_ BareEnvironment,
496              but it is called Environment), no conversions between different
497              kinds of static environments
498    
499       - There is still a notion of a "modmap", but such modmaps are generated
500         on demand at the time when they are needed.  This sounds slow, but I
501         sped up the code that generates modmaps enough for this not to lead to
502         a slowdown of the compiler (at least I didn't detect any).
503    
504       - To facilitate rapid modmap generation, static environments now
505         contain an (optional) "modtree" structure.  Modtree annotations are
506         constructed by the unpickler during unpickling.  (This means that
507         the elaborator does not have to worry about modtrees at all.)
508         Modtrees have the advantage that they are compositional in the same
509         way as the environment data structure itself is compositional.
510         As a result, modtrees never hang on to parts of an environment that
511         has already been rendered "stale" by filtering or rebinding.
512    
513       - I went through many, many trials and errors before arriving at the
514         current solution.  (The initial idea of "linkpaths" did not work.)
515         But the result of all this is that I have touched a lot of files that
516         depend on the "modules" and "types" data structures (most of the
517         elaborator). There were a lot of changes during my "linkpath" trials
518         that could have been reverted to their original state but weren't.
519         Please, don't be too harsh on me for messing with this code a bit more
520         than what was strictly necessary...  (I _did_ resist the tempation
521         of doing any "global reformatting" to avoid an untimely death at
522         Dave's hands. :)
523    
524       - One positive aspect of the previous point:  At least I made sure that
525         all files that I touched now compile without warnings (other than
526         "polyEqual").
527    
528       - compiler now tends to run "leaner" (i.e., ties up less memory in
529         redundant modmaps)

536    Description:
537    
538       This update contains *MAJOR* changes to the way code is generated from CPS
539    in the module mlriscGen, and in various backend modules.
540    
541    CHANGES
542    =======
543    
544    1. MLRiscGen: forward propagation fix.
545    
546       There was a bug in forward propagation introduced at about the same time
547       as the MLRISC x86 backend, which prohibits coalescing to be
548       performed effectively in loops.
549    
550       Effect: speed up of loops in RISC architectures.
551               By itself, this actually slowed down certain benchmarks on the x86.
552    
553    2. MLRiscGen:  forward propagating addresses from consing.
554    
555       I've changed the way consing code is generated.  Basically I separated
556       out the initialization part:
557    
558            store tag,   offset(allocptr)
559            store elem1, offset+4(allocptr)
560            store elem2, offset+8(allocptr)
561            ...
562            store elemn, offset+4n(allocptr)
563    
564       and the address computation part:
565    
566            celladdr <- offset+4+alloctpr
567    
568       and move the address computation part
569    
570       Effect:  register pressure is generally lower as a result.  This
571                makes compilation of certain expressions much faster, such as
572                long lists with non-trivial elements.
573    
574                 [(0,0), (0,0), .... (0,0)]
575    
576    3. MLRiscGen: base pointer elimination.
577    
578        As part of the linkage mechanism, we generate the sequence:
579    
580         L:  ...  <- start of the code fragment
581    
582         L1:
583             base pointer <- linkreg - L1 + L
584    
585         The base pointer was then used for computing relocatable addresses
586       in the code fragment.  Frequently (such as in lots of continuations)
587       this is not needed.  We now eliminate this sequence whenever possible.
588    
589         For compile time efficiency, I'm using a very stupid local heuristic.
590       But in general, this should be done as a control flow analysis.
591    
592       Effect:  Smaller code size.  Speed up of most programs.
593    
594    4. Hppa back end
595    
596         Long jumps in span dependence resolution used to depend on the existence
597      of the base pointer.
598    
599         A jump to a long label L was expanded into the following sequence:
600    
601          LDIL %hi(L-8192), %r29
602          LDO  %lo(L-8192)(%r29), %r29
603          ADD  %r29, baseptr, %r29
604          BV,n %r0(%r29)
605    
606         In the presence of change (3) above, this will not work.  I've changed
607       it so that the following sequence of instructions are generated, which
608       doesn't mention the base pointer at all:
609    
610             BL,n  L', %r29           /* branch and link, L' + 4 -> %r29 */
611        L':  ADDIL L-(L'+4), %r29     /* Compute address of L */
612             BV,n  %r0(%r29)          /* Jump */
613    
614    5. Alpha back end
615    
616          New alpha instructions LDB/LDW have been added, as per Fermin's
617       suggestions.   This is unrelated to all other changes.
618    
619    6. X86 back end
620    
621         I've changed andl to testl in the floating point test sequence
622         whenever appropriate.  The Intel optimization guide states that
623         testl is perferable to andl.
624    
625    7. RA (x86 only)
626    
627         I've improved the spill propagation algorithm, using an approximation
628       of maximal weighted independent sets.   This seems to be necessary to
629       alleviate the negative effect in light of the slow down in (1).
630    
631         I'll write down the algorithm one of these days.
632    
633    8. MLRiscGen: frequencies
634    
635         I've added an annotation that states that all call gc blocks have zero
636       execution frequencies.  This improves register allocation on the x86.
637    
638    BENCHMARKS
639    ==========
640    
641       I've only perform the comparison on 110.25.
642    
643       The platforms are:
644    
645        HPPA  A four processor HP machine (E9000) with 5G of memory.
646        X86   A 300Hhz Pentium II with 128M of memory, and
647        SPARC An Ultra sparc 2 with 512M of memory.
648    
649       I used the following parameters for the SML benchmarks:
650    
651                 @SMLalloc
652         HPPA    256k
653         SPARC   512k
654         X86     256k
655    
656    COMPILATION TIME
657    ----------------
658       Here are the numbers comparing the compilation times of the compilers.
659       I've only compared 110.25 compiling the new sources versus
660       a fixpoint version of the new compiler compiling the same.
661    
662                     110.25                                  New
663               Total  Time in RA  Spill+Reload   Total  Time In RA Spill+Reload
664         HPPA   627s    116s        2684+3584     599s    95s       1003+1879
665         SPARC  892s    173s        2891+3870     708s    116s      1004+1880
666         X86    999s    315s       94006+130691   987s    296s    108877+141957
667    
668                   110.25         New
669                Code Size      Code Size
670         HPPA   8596736         8561421
671         SPARC  8974299         8785143
672         X86    9029180         8716783
673    
674       So in summary, things are at least as good as before.   Dramatic
675       reduction in compilation is obtained on the Sparc; I can't explain it,
676       but it is reproducible.  Perhaps someone should try to reproduce this
677       on their own machines.
678
