19    Description:
20    
21    A quick fix for a problem with GenSML (in the pgraph-util library):
22    Make generation of toplevel "local" optional.  (Strictly speaking,
23    signature definitions within "local" are not legal SML.)
24    
25    Other than that: updates to INSTALL and cm/TODO.

31    Description:
32    
33    0. Version number has been bumped to 110.38.1.  NEW BOOTFILES!!!
34    
35    1. The installer (config/install.sh) has gotten smarter:
36    
37         - Configuration options are a bit easier to specify now
38           (in config/targets).
39         - Bug in recognizing .tar.bz2 files fixed.
40         - Installer automatically resolves dependencies between
41           configuration options (e.g., if you ask for eXene, you will
42           also get cml -- regardless whether you asked for it or not).
43         - Installer can run in "quieter mode" by setting the environment
44           variable INSTALL_QUIETLY to "true".  "Quieter" does not mean
45           "completely silent", though.
46         - Build HashCons library as part of smlnj-lib.
47    
48    2. A new scheme for assigning persistent identifiers to compilation
49       units (and, by extension, to types etc.) has been put into place.
50       This fixes a long-standing bug where types and even dynamic values
51       can get internally confused, thereby compromising type safety
52       (abstraction) and dynamic correctness.  See
53    
54         http://cm.bell-labs.com/cm/cs/who/blume/pid-confusion.tgz
55    
56       for an example of how things could go wrong until now.
57    
58       The downside of the new scheme is that pids are not quite as
59       persistent as they used to be: CM will generate a fresh pid
60       for every compilation unit that it thinks it sees for the first
61       time.  That means that if you compile starting from a clean, fresh
62       source tree at two different times, you end up with different
63       binaries.
64    
65       Cutoff recompilation, however, has not been compromised because
66       CM keeps pid information in special caches between runs.

72    Description:
73    
74    Compilers that generate assembly code may produce  global labels
75    whose value is resolved at link time. The various peephole optimization
76    modules did not take this in account.
77    
78    TODO. The Labels.addrOf function should really return an option
79    type so that clients are forced to deal with this issue, rather
80    than an exception being raised.

86    Description:
87    
88    1. A bug fix from Allen.
89    
90        A typo causes extra fstp %st(0)'s to be generated at compensation
91        edges, which might cause stack underflow traps at runtime.  This
92        occurs in fft where there are extraneous fstps right before the 'into'
93        trap instruction (in this case they are harmless since none of the
94        integers overflow.)
95    
96    2. Pulled out various utility modules that were embedded in the modules
97       of the register allocator. I need these modules for other purposes, but
98       they are not complete enough to put into a library (just yet).

124    Description:
125    
126    - Added somewhat detailed installation instructions (file INSTALL).
127    - Fixed curl-detection bug in config/install.sh.
128    - It is now possible to select the URL getter using the URLGETTER
129      environment variable:
130    
131          not set / "unknown"      --> automatic detection (script tries wget,
132                                       curl, and lynx)
133          "wget" / "curl" / "lynx" --> use the specified program (script "knows"
134                                       how to properly invoke them)
135          other                    --> use $URLGETTER directly, it must take
136                                       precisely two command-line arguments
137                                       (source URL and destination file name)

172    
173    0. Retracted earlier 110.38.  (The Release_110_38 tag has been replaced
174       with blume-Release_110_38-retracted.)
175    
176    1. Fixed a problem with incorrect rounding modes in real64.sml.
177       (Thanks to Andrew Mccreight <andrew.mccreight@yale.edu>.)
178    
179    2. A bug in ml-nlffigen related to the handling of unnamed structs, unions,
180       and enums fixed.  The naming of corresponding ML identifiers should
181       now be consistent again.

210    Description:
211    
212    A large number of tweaks and improvements to ml-nlffi-lib and
213    ml-nlffigen:
214    
215       - ML represenation types have been streamlined
216       - getter and setter functions work with concrete values, not abstract
217         ones where possible
218       - ml-nlffigen command line more flexible (see README file there)
219       - some bugs have been fixed (hopefully)

245    
246    Another day of fiddling with the FFI...
247    
248    1. Bug fix/workaround:  CKIT does not complain about negative array
249       dimensions, so ml-nlffigen has to guard itself against this possibility.
250       (Otherwise a negative dimension would send it into an infinite loop.)
251    
252    2. Some of the abstract types (light objects, light pointers, most "base"
253       types) in structure C are now eqtypes.
254    
255    3. Added constructors and test functions for NULL function pointers.

272    Description:
273    
274    Today's FFI fiddling:
275    
276      - Provided a structure CGetSet with "convenient" versions of C.Get.* and
277        C.Set.* that use concrete (MLRep.*) arguments and results instead
278        of abstract ones.
279    
280      - Provided word-style bit operations etc. for "int" representation
281        types in MLRep.S<Foo>Bitops where <Foo> ranges over Char, Int, Short,
282        and Long.

288    Description:
289    
290    Now that x86-fast-fp seems to be working, I turned it back on again
291    by default.  (Seems to work fine now, even with the FFI.)
292    
293    Other than that, I added some documentation about the FFI to
294    src/ml-nlffigen/README and updated the FFI test examples in
295    src/ml-nlffi-lib/Tests/*.

306       2. Minor pretty printing fix for cellset.  Print %st(0) as %st(0) instead
307          of %f32.
308    
309       3. Added a constructor INT32lit to the ast of MLRISC tools.

315    Description:
316    
317    More fiddling with the FFI interface:
318    
319     - Make constness 'c instead of rw wherever possible.  This eliminates
320       the need for certain explicit coercions.  (However, due to ML's
321       value polymorphism, there will still be many cases where explicit
322       coercions are necessary.  Phantom types are not the whole answer
323       to modeling a subtyping relationship in ML.)
324    
325     - ro/rw coersions for pointers added.  (Avoids the detour through */&.)
326    
327     - "printf" test example added to src/ml-nlffi-lib/Tests.  (Demonstrates
328       clumsy workaround for varargs problem.)

347    
348    1. Fix for bug resulting in single-precision float values being returned
349       incorrectly from FFI calls.
350    
351    2. Small modifications to C FFI API:
352    
353        - memory-allocation routines return straight objects (no options)
354          and raise an exception in out-of-memory situations
355        - unsafe extensions to cast between function pointers and pointers
356          from/to ints
357        - added structure C_Debug as an alternative to structure C where
358          pointer-dereferencing (|*| and |*!) always check for null-pointers
359        - added open_lib' to DynLinkage;  open_lib' works like open_lib
360          but also takes a (possibly empty) list of existing library handles
361          that the current library depends on

382            Removed the native COPY and FCOPY instructions
383            from all the architectures and replaced it with the

385    
386            It is now possible to simplify many of the optimizations

393    Tag: george-20011206-mlrisc-instruction
394    Description:
395    
396    Changed the representation of instructions from being fully abstract
397    to being partially concrete. That is to say:
398    
399      from
400            type instruction
401    
402      to
403            type instr                              (* machine instruction *)
404    
405            datatype instruction =
406                LIVE of {regs: C.cellset, spilled: C.cellset}
407              | KILL of {regs: C.cellset, spilled: C.cellset}
408              | COPYXXX of {k: CB.cellkind, dst: CB.cell list, src: CB.cell list}
409              | ANNOTATION of {i: instruction, a: Annotations.annotation}
410              | INSTR of instr
411    
412    This makes the handling of certain special instructions that appear on
413    all architectures easier and uniform.
414    
415    LIVE and KILL say that a list of registers are live or killed at the
416    program point where they appear. No spill code is generated when an
417    element of the 'regs' field is spilled, but the register is moved to
418    the 'spilled' (which is present, more for debugging than anything else).
419    
420    LIVE replaces the (now deprecated) DEFFREG instruction on the alpha.
421    We used to generate:
422    
423            DEFFREG f1
424            f1 := f2 + f3
425            trapb
426    
427    but now generate:
428    
429            f1 := f2 + f3
430            trapb
431            LIVE {regs=[f1,f2,f3], spilled=[]}
432    
433    Furthermore, the DEFFREG (hack) required that all floating point instruction
434    use all registers mentioned in the instruction. Therefore f1 := f2 + f3,
435    defines f1 and uses [f1,f2,f3]! This hack is no longer required resulting
436    in a cleaner alpha implementation. (Hopefully, intel will not get rid of
437    this architecture).
438    
439    COPYXXX is intended to replace the parallel COPY and FCOPY  available on
440    all the architectures. This will result in further simplification of the
441    register allocator that must be aware of them for coalescing purposes, and
442    will also simplify certain aspects of the machine description that provides
443    callbacks related to parallel copies.
444    
445    ANNOTATION should be obvious, and now INSTR represents the honest to God
446    machine instruction set!
447    
448    The <arch>/instructions/<arch>Instr.sml files define certain utility
449    functions for making porting easier -- essentially converting upper case
450    to lower case. All machine instructions (of type instr) are in upper case,
451    and the lower case form generates an MLRISC instruction. For example on
452    the alpha we have:
453    
454      datatype instr =
455         LDA of {r:cell, b:cell, d:operand}
456       | ...
457    
458      val lda : {r:cell, b:cell, d:operand} -> instruction
459        ...
460    
461    where lda is just (INSTR o LDA), etc.

493    Description:
494    
495    Note: I removed the original tag "Release_110_37" from this commit
496          because we found a serious bug in all non-x86 backends.
497          - Matthias
498    
499    1. Modifications to the SML/NJ code generator and to the runtime system
500       so that code object name strings are directly inserted into code
501       objects at code generation time.  The only business the runtime system
502       has with this is now to read the name strings on occasions.
503       (The encoding of the name string has also changed somewhat.)
504    
505    2. CM now implements a simple "set calculus" for specifying export lists.
506       In particular, it is now possible to refer to the export lists of
507       other libraries/groups/sources and form unions as well as differences.
508       See the latest CM manual for details.
509    
510    3. An separate notion of "proxy" libraries has again be eliminated from
511       CM's model.  (Proxy libraries are now simply a special case of using
512       the export list calculus.)
513    
514    4. Some of the existing libraries now take advantage of the new set
515       calculus.
516       (Notice that not all libraries have been converted because some
517       of the existing .cm-files are supposed to be backward compatible
518       with 110.0.x.)
519    
520    5. Some cleanup in stand-alone programs.  (Don't use "exnMessage" -- use
521       "General.exnMessage"!  The former relies on a certain hook to be
522       initialized, and that often does not happen in the stand-alone case.)

528    Description:
529    
530      Implemented a complete redesign of MLRISC pseudo-ops. Now there
531      ought to never be any question of incompatabilities with
532      pseudo-op syntax expected by host assemblers.
533    
534      For now, only modules supporting GAS syntax are implemented
535      but more should follow, such as MASM, and vendor assembler
536      syntax, e.g. IBM as, Sun as, etc.

549       I put out the other day.  (The proposal notwithstanding, things are
550       still in flux here.)

557    
558      Fix for a backpatching bug reported by Allen.
559    
560      Because the boundary between short and long span-dependent
561      instructions is +/- 128, there are an astounding number of
562      span-dependent instructions whose size is over estimated.
563    
564      Allen came up with the idea of letting the size of span
565      dependent instructions be non-monotonic, for a maxIter
566      number of times, after which the size must be monotonically
567      increasing.
568    
569      This table shows the number of span-dependent instructions
570      whose size was over-estimated as a function of maxIter, for the
571      file Parse/parse/ml.grm.sml:
572    
573         maxIter            # of instructions:
574            10                      687
575            20                      438
576            30                      198
577            40                        0
578    
579      In compiling the compiler, there is no significant difference in
580      compilation speed between maxIter=10 and maxIter=40. Actually,
581      my measurements showed that maxIter=40 was a tad faster than
582      maxIter=10! Also 96% of the  files in the compiler reach a fix
583      point within 13 iterations, so fixing maxIter at 40, while high,
584      is okay.

590    Description:
591    
592    CKIT:
593    * Changed the "Function" constructor of type Ast.ctype to carry optional
594      argument identifiers.
595    * Changed the return type of TypeUtil.getFunction accordingly.
596    * Type equality ignores the argument names.
597    * TypeUtil.composite tries to preserve argument names but gives up quickly
598      if there is a mismatch.
599    
600    installation script:
601    * attempts to use "curl" if available (unless "wget" is available as well)
602    
603    CM:
604    * has an experimental implementation of "portable graphs" which I will
605      soon propose as an implementation-independent library format
606    * there are also new libraries $/pgraph.cm and $/pgraph-util.cm
607    
608    NLFFI-LIB:
609    * some cleanup (all cosmetic)
610    
611    NLFFIGEN:
612    * temporarily disabled the mechanism that suppresses ML output for
613      C definitions whose identifiers start with an underscore character
614    * generate val bindings for enum constants
615    * user can request that only one style (light or heavy) is being used;
616      default is to use both (command-line arguments: -heavy and -light)
617    * fixed bug in handling of function types involving incomplete pointers
618    * generate ML entry points that take record arguments (i.e., using
619      named arguments) for C functions that have a prototype with named
620      arguments
621      (see changes to CKIT)

675    Description:
676    
677    I provided a non-hook implementation of exnName (at the toplevel) and
678    made the "dummy" implementation of exnMessage (at the toplevel) more
679    useful: if nothing gets "hooked in", then at least you are going to
680    see the exception name and a message indicating why you don't see more.
681    
682    [For the time being, programs that need exnMessage and want to use
683    ml-build should either use General.exnMessage (strongly recommended) or
684    refer to structure General at some other point so that CM sees a
685    static dependency.]
686    
687    [Similar remarks go for "print" and "use":  If you want to use their
688    functionality in stand-alone programs generated by ml-build, then use
689    TextIO.output and Backend.Interact.useFile (from $smlnj/compiler.cm).]

710    2. Changed config/_run-sml (resulting in a changed bin/.run-sml) so
711       that arguments that contain delimiters are passed through correctly.
712       This change also means that all "special" arguments of the form
713       @SMLxxx... must come first.

826    
827    !!!! NEW BOOTFILES !!!!
828    
829    This is another round of reorganizing the compiler sources.  This
830    time the main goal was to factor out all the "instrumentation"
831    passes (for profiling and backtracing) into their own library.
832    The difficulty was to do it in such a way that it does not depend
833    on elaborate.cm but only on elabdata.cm.
834    
835    Therefore there have been further changes to both elaborate.cm and
836    elabdata.cm -- more "generic" things have been moved from the former
837    to the latter.  As a result, I was forced to split the assignment
838    of numbers indicating "primtyc"s into two portions: SML-generic and
839    SML/NJ-specific.  Since it would have been awkward to maintain,
840    I bit the bullet and actually _changed_ the mapping between these
841    numbers and primtycs.  The bottom line of this is that you need
842    a new set of bin- and bootfiles.
843    
844    I have built new bootfiles for all architectures, so doing a fresh
845    checkout and config/install.sh should be all you need.
846    
847    The newly created library's name is
848    
849        $smlnj/viscomp/debugprof.cm
850    
851    and its sources live under
852    
853        src/compiler/DebugProf
