21    0. Retracted earlier 110.38.  (The Release_110_38 tag has been replaced
22       with blume-Release_110_38-retracted.)
23    
24    1. Fixed a problem with incorrect rounding modes in real64.sml.
25       (Thanks to Andrew Mccreight <andrew.mccreight@yale.edu>.)
26    
27    2. A bug in ml-nlffigen related to the handling of unnamed structs, unions,
28       and enums fixed.  The naming of corresponding ML identifiers should
29       now be consistent again.

36    
37       Added a target called nowhere in the configuration scripts.
38       Enabling this will build the MLRISC 'nowhere' tool (for translating
39       programs with where-clauses into legal SML code) during installation.

58    Description:
59    
60    A large number of tweaks and improvements to ml-nlffi-lib and
61    ml-nlffigen:
62    
63       - ML represenation types have been streamlined
64       - getter and setter functions work with concrete values, not abstract
65         ones where possible
66       - ml-nlffigen command line more flexible (see README file there)
67       - some bugs have been fixed (hopefully)

93    
94    Another day of fiddling with the FFI...
95    
96    1. Bug fix/workaround:  CKIT does not complain about negative array
97       dimensions, so ml-nlffigen has to guard itself against this possibility.
98       (Otherwise a negative dimension would send it into an infinite loop.)
99    
100    2. Some of the abstract types (light objects, light pointers, most "base"
101       types) in structure C are now eqtypes.
102    
103    3. Added constructors and test functions for NULL function pointers.

122    Today's FFI fiddling:
123    
124      - Provided a structure CGetSet with "convenient" versions of C.Get.* and
125        C.Set.* that use concrete (MLRep.*) arguments and results instead
126        of abstract ones.
127    
128      - Provided word-style bit operations etc. for "int" representation
129        types in MLRep.S<Foo>Bitops where <Foo> ranges over Char, Int, Short,
130        and Long.

137    
138    Now that x86-fast-fp seems to be working, I turned it back on again
139    by default.  (Seems to work fine now, even with the FFI.)
140    
141    Other than that, I added some documentation about the FFI to
142    src/ml-nlffigen/README and updated the FFI test examples in
143    src/ml-nlffi-lib/Tests/*.

151       1. Fixed a problem with handling return fp values when x86's fast fp
152          mode is turned on.
153    
154       2. Minor pretty printing fix for cellset.  Print %st(0) as %st(0) instead
155          of %f32.
156    
157       3. Added a constructor INT32lit to the ast of MLRISC tools.

163    Description:
164    
165    More fiddling with the FFI interface:
166    
167     - Make constness 'c instead of rw wherever possible.  This eliminates
168       the need for certain explicit coercions.  (However, due to ML's
169       value polymorphism, there will still be many cases where explicit
170       coercions are necessary.  Phantom types are not the whole answer
171       to modeling a subtyping relationship in ML.)
172    
173     - ro/rw coersions for pointers added.  (Avoids the detour through */&.)
174    
175     - "printf" test example added to src/ml-nlffi-lib/Tests.  (Demonstrates
176       clumsy workaround for varargs problem.)

184    1. Since COPY instructions are no longer native to the architecture,
185       a generic functor can be used to implement the expandCopies function.
186

188       TEXT segment.

194    Description:
195    
196    1. Fix for bug resulting in single-precision float values being returned
197       incorrectly from FFI calls.
198    
199    2. Small modifications to C FFI API:
200    
201        - memory-allocation routines return straight objects (no options)
202          and raise an exception in out-of-memory situations
203        - unsafe extensions to cast between function pointers and pointers
204          from/to ints
205        - added structure C_Debug as an alternative to structure C where
206          pointer-dereferencing (|*| and |*!) always check for null-pointers
207        - added open_lib' to DynLinkage;  open_lib' works like open_lib
208          but also takes a (possibly empty) list of existing library handles
209          that the current library depends on

219    2. Major update to ml-nlffigen and ml-nlffi-lib.  Things are much
220       more scalable now so that even huge interfaces such as the one
221       for GTK compile in finite time and space. :-)

227    Tag: george-20011206-rm-native-copy
228    Description:
229    
230            Removed the native COPY and FCOPY instructions
231            from all the architectures and replaced it with the
232            explicit COPY instruction from the previous commit.
233    
234            It is now possible to simplify many of the optimizations
235            modules that manipulate copies. This has not been
236            done in this change.

241    Tag: george-20011206-mlrisc-instruction
242    Description:
243    
244    Changed the representation of instructions from being fully abstract
245    to being partially concrete. That is to say:
246    
247      from
248            type instruction
249    
250      to
251            type instr                              (* machine instruction *)
252    
253            datatype instruction =
254                LIVE of {regs: C.cellset, spilled: C.cellset}
255              | KILL of {regs: C.cellset, spilled: C.cellset}
256              | COPYXXX of {k: CB.cellkind, dst: CB.cell list, src: CB.cell list}
257              | ANNOTATION of {i: instruction, a: Annotations.annotation}
258              | INSTR of instr
259    
260    This makes the handling of certain special instructions that appear on
261    all architectures easier and uniform.
262    
263    LIVE and KILL say that a list of registers are live or killed at the
264    program point where they appear. No spill code is generated when an
265    element of the 'regs' field is spilled, but the register is moved to
266    the 'spilled' (which is present, more for debugging than anything else).
267    
268    LIVE replaces the (now deprecated) DEFFREG instruction on the alpha.
269    We used to generate:
270    
271            DEFFREG f1
272            f1 := f2 + f3
273            trapb
274    
275    but now generate:
276    
277            f1 := f2 + f3
278            trapb
279            LIVE {regs=[f1,f2,f3], spilled=[]}
280    
281    Furthermore, the DEFFREG (hack) required that all floating point instruction
282    use all registers mentioned in the instruction. Therefore f1 := f2 + f3,
283    defines f1 and uses [f1,f2,f3]! This hack is no longer required resulting
284    in a cleaner alpha implementation. (Hopefully, intel will not get rid of
285    this architecture).
286    
287    COPYXXX is intended to replace the parallel COPY and FCOPY  available on
288    all the architectures. This will result in further simplification of the
289    register allocator that must be aware of them for coalescing purposes, and
290    will also simplify certain aspects of the machine description that provides
291    callbacks related to parallel copies.
292    
293    ANNOTATION should be obvious, and now INSTR represents the honest to God
294    machine instruction set!
295    
296    The <arch>/instructions/<arch>Instr.sml files define certain utility
297    functions for making porting easier -- essentially converting upper case
298    to lower case. All machine instructions (of type instr) are in upper case,
299    and the lower case form generates an MLRISC instruction. For example on
300    the alpha we have:
301    
302      datatype instr =
303         LDA of {r:cell, b:cell, d:operand}
304       | ...
305    
306      val lda : {r:cell, b:cell, d:operand} -> instruction
307        ...
308    
309    where lda is just (INSTR o LDA), etc.

340    Tag: blume-20011121-invalid_110_37
341    Description:
342    
343    Note: I removed the original tag "Release_110_37" from this commit
344          because we found a serious bug in all non-x86 backends.
345          - Matthias
346    
347    1. Modifications to the SML/NJ code generator and to the runtime system
348       so that code object name strings are directly inserted into code
349       objects at code generation time.  The only business the runtime system
350       has with this is now to read the name strings on occasions.
351       (The encoding of the name string has also changed somewhat.)
352    
353    2. CM now implements a simple "set calculus" for specifying export lists.
354       In particular, it is now possible to refer to the export lists of
355       other libraries/groups/sources and form unions as well as differences.
356       See the latest CM manual for details.
357    
358    3. An separate notion of "proxy" libraries has again be eliminated from
359       CM's model.  (Proxy libraries are now simply a special case of using
360       the export list calculus.)
361    
362    4. Some of the existing libraries now take advantage of the new set
363       calculus.
364       (Notice that not all libraries have been converted because some
365       of the existing .cm-files are supposed to be backward compatible
366       with 110.0.x.)
367    
368    5. Some cleanup in stand-alone programs.  (Don't use "exnMessage" -- use
369       "General.exnMessage"!  The former relies on a certain hook to be
370       initialized, and that often does not happen in the stand-alone case.)

378      Implemented a complete redesign of MLRISC pseudo-ops. Now there
379      ought to never be any question of incompatabilities with
380      pseudo-op syntax expected by host assemblers.
381    
382      For now, only modules supporting GAS syntax are implemented
383      but more should follow, such as MASM, and vendor assembler
384      syntax, e.g. IBM as, Sun as, etc.

405    
406      Fix for a backpatching bug reported by Allen.
407    
408      Because the boundary between short and long span-dependent
409      instructions is +/- 128, there are an astounding number of
410      span-dependent instructions whose size is over estimated.
411    
412      Allen came up with the idea of letting the size of span
413      dependent instructions be non-monotonic, for a maxIter
414      number of times, after which the size must be monotonically
415      increasing.
416    
417      This table shows the number of span-dependent instructions
418      whose size was over-estimated as a function of maxIter, for the
419      file Parse/parse/ml.grm.sml:
420    
421         maxIter            # of instructions:
422            10                      687
423            20                      438
424            30                      198
425            40                        0
426    
427      In compiling the compiler, there is no significant difference in
428      compilation speed between maxIter=10 and maxIter=40. Actually,
429      my measurements showed that maxIter=40 was a tad faster than
430      maxIter=10! Also 96% of the  files in the compiler reach a fix
431      point within 13 iterations, so fixing maxIter at 40, while high,
432      is okay.

443    * Changed the return type of TypeUtil.getFunction accordingly.
444    * Type equality ignores the argument names.

455    
456    NLFFI-LIB:
457    * some cleanup (all cosmetic)
458    
459    NLFFIGEN:
460    * temporarily disabled the mechanism that suppresses ML output for
461      C definitions whose identifiers start with an underscore character
462    * generate val bindings for enum constants
463    * user can request that only one style (light or heavy) is being used;
464      default is to use both (command-line arguments: -heavy and -light)
465    * fixed bug in handling of function types involving incomplete pointers
466    * generate ML entry points that take record arguments (i.e., using
467      named arguments) for C functions that have a prototype with named
468      arguments

522    Tag: blume-20010925-exninfo
523    Description:
524    
525    I provided a non-hook implementation of exnName (at the toplevel) and
526    made the "dummy" implementation of exnMessage (at the toplevel) more
527    useful: if nothing gets "hooked in", then at least you are going to
528    see the exception name and a message indicating why you don't see more.
529    
530    [For the time being, programs that need exnMessage and want to use
531    ml-build should either use General.exnMessage (strongly recommended) or
532    refer to structure General at some other point so that CM sees a
533    static dependency.]
534    
535    [Similar remarks go for "print" and "use":  If you want to use their
536    functionality in stand-alone programs generated by ml-build, then use
537    TextIO.output and Backend.Interact.useFile (from $smlnj/compiler.cm).]

551    Description:
552    
553    0. Updated the BOOT file (something that I forgot to do earlier).
554    
555    1. Small internal change to CM so that it avoids "/../" in filenames
556       as much as possible (but only where it is safe).
557    
558    2. Changed config/_run-sml (resulting in a changed bin/.run-sml) so
559       that arguments that contain delimiters are passed through correctly.
560       This change also means that all "special" arguments of the form
561       @SMLxxx... must come first.
562    
563    3. Changed install script to put relative anchor names for tool commands
564       into pathconfig.

595    Description:
596    
597    John committed some changes that Allen made, in particular a (hopefully)
598    correctly working version of the x86-fp module.
599    
600    I changed the default setting of the Control.MLRISC.getFlag "x86-fast-fp"
601    flag to "true".  Everything seems to compile to a fixpoint ok, and
602    "mandelbrot" speeds up by about 15%.

610    1. Stefan Monnier's patch to fix a miscompilation problem that

613    2. Implemented a minimal "structure Compiler" that contains just
614       "version" and "architecture".  The minimal version will be
615       available when the full version is not.  This is for backward-
616       compatibility with code that wants to test Compiler.version.

674    Description:
675    
676    !!!! NEW BOOTFILES !!!!
677    
678    This is another round of reorganizing the compiler sources.  This
679    time the main goal was to factor out all the "instrumentation"
680    passes (for profiling and backtracing) into their own library.
681    The difficulty was to do it in such a way that it does not depend
682    on elaborate.cm but only on elabdata.cm.
683    
684    Therefore there have been further changes to both elaborate.cm and
685    elabdata.cm -- more "generic" things have been moved from the former
686    to the latter.  As a result, I was forced to split the assignment
687    of numbers indicating "primtyc"s into two portions: SML-generic and
688    SML/NJ-specific.  Since it would have been awkward to maintain,
689    I bit the bullet and actually _changed_ the mapping between these
690    numbers and primtycs.  The bottom line of this is that you need
691    a new set of bin- and bootfiles.
692    
693    I have built new bootfiles for all architectures, so doing a fresh
694    checkout and config/install.sh should be all you need.
695    
696    The newly created library's name is
697    
698        $smlnj/viscomp/debugprof.cm
699    
700    and its sources live under
701    
702        src/compiler/DebugProf
