19    Description:
20    
21    Fixed problem with IntInf.fmt (sign would show up on the right instead
22    of on the left for BIN, OCT, and HEX).

28    Description:
29    
30    Fixed problem with installer script (unix only) where bin/ml-yacc and
31    friends pointed (via symlinks) to absolute locations instead of just
32    .run-sml.  This was reported by Vesa A Norrman.

80    Tag: blume-20031104-move-libraries
81    Description:
82    
83    Eliminated the "dont_move_libraries" directive in config/targets.
84    (The mechanism was broken and could not be fixed easily.  Moreover,
85    there does not seem to be any reason not to move all libraries into
86    lib during installation.  I originally implemented this directive as a
87    backward-compatibility feature when I first introduced the new CM.
88    Now that things have been stable for a long time and going back to the
89    old CM is not an option, there is no reason to keep it around.)

138    Tag: blume-20030926-ppautoload
139    Description:
140    
141    I modified the read-eval-print loop so that the autoloader gets
142    invoked whenever the prettyprinter tries to look up a symbol that
143    is not currently defined in the toplevel environment but which
144    appears in CM's autoload registry.  As a result, we see far fewer of
145    those ?.Foo.Bar.xxx names in the prettyprinter's output.
146    
147    In addition to this I tried to clean up some pieces of the Basis
148    implementation (e.g., Socket, Word8Array) in order to prevent other
149    instances of these ?.Foo.Bar.xxx names from being printed.
150    
151    The mechanism that picks names for types still needs some work, though.
152    (Right now it seems that if there is a type A.t which is defined to
153    be B.u, but B is unavailable at toplevel, then A.t gets printed as
154    "?.B.u" although the perhaps more sensible solution would be to use
155    "A.t" in this case.  In other words, the prettyprinter should follow
156    a chain of DEFtycs not farther than there are corresponding toplevel
157    names in the current environment.)

162    Tag: blume-20030924-installer
163    Description:
164    
165    Another installer tweak:  All the ML code for the installer is now
166    compiled during CMB.make and put into a little library called
167    $smlnj/installer.cm.  The installation then simply invokes
168    
169       sml -m $smlnj/installer.cm
170    
171    and everything happens automagically.
172    
173    Win32:  ML code senses value of environment variable SMLNJ_HOME.
174    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
175            and BINDIR.
176    
177    The new scheme guarantees that the ML code responsible for the installation
178    is in sync with the APIs of the main system.  Also, the installer is
179    somewhat faster because the installer script is precompiled.

184    Tag: blume-20030924-synsock
185    Description:
186    
187    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
188    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
189    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
190    implementations of non-blocking operations from CML's Socket
191    structure.

196    Tag: blume-20030924-sockets
197    Description:
198    
199    1. Fixed SOCKET API and implementation to match Basis spec.
200       This required changing the internal representation of sockets to one
201       that remembers (for each socket file descriptor) whether it is currently
202       blocking or non-blocking.  This state is maintained lazily (i.e., a system
203       call is made only if the state actually needs to change).
204    
205    2. OS-specific details of sockets were moved into separate files, thus
206       making it possible to unify the bulk of the socket implementations
207       between Unix and Win32.
208    
209    3. CML's socket API changed accordingly.
210       (Note that we need to remove non-blocking functions from this API
211       since they are redundant in the case of CML!)
212    
213    4. CML's socket implementation now makes use of non-blocking functions
214       provided by Basis, thus removing all OS-dependent code from this part
215       of CML.
216    
217    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

234    Description:
235    
236    1. new-install.sh -> install.sh
237    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
238    3. tweaked installer so that another name instead of .cm can be chosen
239       at install time (by setting the CM_DIR_ARC environment variable
240       during installation); once installation is complete, the name is
241       fixed

260    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
261       this seems to be controversial at the moment) and used those in
262       Posix.ProcEnv.times.
263    
264    2. Added Time.{from,to}Nanoseconds to Time.
265    
266    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
267       For example, fromLargeInt never needs to look at more than 3 "big
268       digits" to get its 53 bits of precision.

274    Description:
275    
276    Added an entry to the primitive environment
277    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
278    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
279    
280    Removed some of the "magic" constants in real64.sml and replaced them
281    with code that generates these values from their corresponding
282    integer counterparts.
283    
284    Made all(?) the slice-related changes to the Basis and made everything
285    compile again...

301    Minor bugfix in config/libinstall (set anchor with path to

329    Tag: blume-20030909-installer
330    Description:
331    
332    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
333    Modified config/install.bat to take advantage of it.  Also modified
334    config/install.sh (and called it config/new-install.sh) to take advantage
335    of it on Unix systems.  (The SML code is (supposed to be) platform-
336    independent.)
337    
338    The installer can now install everything under Win32
339    as well as under *nix as long as it compiles.
340    
341    Other changes:
342    
343      - made CML compile again under Win32
344      - made eXene compile under Win32 (by providing a fake structure UnixSock
345        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
346      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
347        same as type int;  under Win32 it isn't
348      - fixed some slice-related problems in the win32-specific parts of CML
349      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
350        (under Win32, the volume name is case-insensitive, and the
351        OS.Path code compares volume names for equality)

360    when given an empty string.  This is what the spec says, and incidentally,
361    CM depends on it.  (CM otherwise goes into an infinite loop in certain
362    cases when presented with the name of a non-existing .cm file.)

367    Tag: blume-20030905-slices-etc
368    Description:
369    
370      1. Changed interface to vectors and arrays in Basis to match
371         (draft) Basis spec.
372      2. Added signatures and implementations of slices according to
373         Basis spec.
374      3. Edited source code throughout the system to make it compile again
375         under 1. and 2.  (In some cases code had to be added to have it
376         match the new signatures.)
377      4. MLRISC should be backward-compatible: the copies of the originals
378         of files that needed to change under 3. were retained, the .cm files
379         check the compiler version number and use old versions when
380         appropriate.
381      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
382         dirstream -> string option (in accordance with Basis spec).
383      6. When generating code that counts lines, ml-lex used function
384         CharVector.foldli, taking advantage of its old interface.
385         This has been replaced with the corresponding code from
386         CharVectorSlice.  (html-lex must be re-lexed!)
387      7. BitArray in smlnj-lib/Util has been extended/modified to match the
388         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
389      8. Removed temporary additions (fromInternal, toInternal) from the
390         (now obsolete) IntInf in smlnj-lib/Util.
391      9. Cleaned up structure Byte.
392     10. Added localOffset, scan, and fromString to Date (according to spec).
393         Cleaned/corrected implementation of Date.
394         (Still need to check for correctness; implement better canonicalizeDate.)
395     11. Added "scan" to signature IEEE_REAL.
396     12. Some improvements to IntInf [in particular: efficiency-hack for
397         mod and rem when second operand is 2 (for parity checks).]
398     13. Changed representation of type Time.time, using a single IntInf.int
399         value counting microseconds.  This considerably simplified the
400         implementation of structure Time.  We now support negative time
401         values; scan and fromString handle signs.
402     14. Functor PrimIO now takes two additional arguments (VectorSlice and
403         ArraySlice).

408    Tag: blume-20030828-intinf
409    Description:
410    
411    This is a major update which comes with a version number bump
412    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
413    and an implementation of IntInf in the Basis.
414    
415    There are a fairly large number of related changes and updates throughout
416    the system:
417    
418    Basis:
419            - Implemented IntInf.
420            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
421            - Added some missing Real64 operations, most notably Real.toLargeInt.
422            - Added FixedInt as a synonym for Int32.
423    
424    compiler:
425            * Added support for a built-in intinf type.
426              - literals
427              - pattern matching
428              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
429              - overloading on literals and operations
430    
431            This required adding a primitive type intinf, some additional
432            primops, and implementations for several non-trivial intinf
433            operations in Core.  (The intinf type is completely abstract
434            to the compiler; all operations get delegated back to the Core.)
435    
436            * Intinf equality is handled by polyequal.  However, the compiler
437            does not print its usual warning in this case (since polyequal
438            is the right thing to do there).
439    
440            * Improved the organization of structure InlineT.
441    
442            * A word about conversion primops:
443            If conversions involving intinf do not cancel out during
444            CPS contract, then the compiler must insert calls to Core functions.
445            Since all core access must be resolved already during the FLINT
446            translate phase, it would be too late a the time of CPS contract
447            to add new Core calls.  For this reason, conversion primops
448            for intinf carry two arguments:  1. the numeric argument that
449            they are supposed to convert, and 2. the Core function that
450            can help with this conversion if necessary.  If CPS contract
451            eliminates a primop, then the associated Core function becomes
452            dead and goes away.  Intinf conversion primops that do not get
453            eliminated by CPS contract get rewritten into calls of their
454            core functions by a separate, new phase.
455    
456    interactive system:
457            - Control.Print.intinfDepth controls max length of intinf constants
458            being printed. (Analogous to Control.Print.stringDepth.)
459            - Cleanup in printutil and pputil: got rid of unused stuff and
460            duplicates; replaced some of the code with code that makes better
461            use of library functionality.
462    
463    CM:
464            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
465            are no longer silent.
466    
467    CKIT:
468            Fixed mismatched uses of Int32 and LargeInt.  I always decided
469            in favor of LargeInt -- which is now the same as IntInf.
470            CKIT-knowledgable people should check whether this is what's
471            intended and otherwise change things back to using Int32 or
472            FixedInt.
473    
474    Throughout the code:
475            Started using IntInf.int literals and built-in operations
476            (e.g., comparison with 0) where this seems appropriate.

483    Description:
484    
485    Merging changes from the mcz-branch development branch into trunk.
486    These changes involve replacement of the emulated old prettyprinter
487    interface with direct use of the SML/NJ Lib PP library, and fixing
488    of a couple of bugs (895, 1186) relating to error messages.  A new
489    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
490    has been added.
