19    Description:
20    
21    1. new-install.sh -> install.sh
22    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
23    3. tweaked installer so that another name instead of .cm can be chosen
24       at install time (by setting the CM_DIR_ARC environment variable
25       during installation); once installation is complete, the name is
26       fixed

43    Description:
44    
45    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
46       this seems to be controversial at the moment) and used those in
47       Posix.ProcEnv.times.
48    
49    2. Added Time.{from,to}Nanoseconds to Time.
50    
51    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
52       For example, fromLargeInt never needs to look at more than 3 "big
53       digits" to get its 53 bits of precision.

59    Description:
60    
61    Added an entry to the primitive environment
62    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
63    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
64    
65    Removed some of the "magic" constants in real64.sml and replaced them
66    with code that generates these values from their corresponding
67    integer counterparts.
68    
69    Made all(?) the slice-related changes to the Basis and made everything
70    compile again...

86    Minor bugfix in config/libinstall (set anchor with path to
87    standalone tool after installing it, otherwise libraries that
88    need ml-lex or ml-yacc won't compile the first time the installer
89    runs).

114    Tag: blume-20030909-installer
115    Description:
116    
117    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
118    Modified config/install.bat to take advantage of it.  Also modified
119    config/install.sh (and called it config/new-install.sh) to take advantage
120    of it on Unix systems.  (The SML code is (supposed to be) platform-
121    independent.)
122    
123    The installer can now install everything under Win32
124    as well as under *nix as long as it compiles.
125    
126    Other changes:
127    
128      - made CML compile again under Win32
129      - made eXene compile under Win32 (by providing a fake structure UnixSock
130        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
131      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
132        same as type int;  under Win32 it isn't
133      - fixed some slice-related problems in the win32-specific parts of CML
134      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
135        (under Win32, the volume name is case-insensitive, and the
136        OS.Path code compares volume names for equality)

142    Description:
143    
144    Made Win32 version of OS.FileSys.fullPath return current directory
145    when given an empty string.  This is what the spec says, and incidentally,
146    CM depends on it.  (CM otherwise goes into an infinite loop in certain
147    cases when presented with the name of a non-existing .cm file.)

152    Tag: blume-20030905-slices-etc
153    Description:
154    
155      1. Changed interface to vectors and arrays in Basis to match
156         (draft) Basis spec.
157      2. Added signatures and implementations of slices according to
158         Basis spec.
159      3. Edited source code throughout the system to make it compile again
160         under 1. and 2.  (In some cases code had to be added to have it
161         match the new signatures.)
162      4. MLRISC should be backward-compatible: the copies of the originals
163         of files that needed to change under 3. were retained, the .cm files
164         check the compiler version number and use old versions when
165         appropriate.
166      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
167         dirstream -> string option (in accordance with Basis spec).
168      6. When generating code that counts lines, ml-lex used function
169         CharVector.foldli, taking advantage of its old interface.
170         This has been replaced with the corresponding code from
171         CharVectorSlice.  (html-lex must be re-lexed!)
172      7. BitArray in smlnj-lib/Util has been extended/modified to match the
173         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
174      8. Removed temporary additions (fromInternal, toInternal) from the
175         (now obsolete) IntInf in smlnj-lib/Util.
176      9. Cleaned up structure Byte.
177     10. Added localOffset, scan, and fromString to Date (according to spec).
178         Cleaned/corrected implementation of Date.
179         (Still need to check for correctness; implement better canonicalizeDate.)
180     11. Added "scan" to signature IEEE_REAL.
181     12. Some improvements to IntInf [in particular: efficiency-hack for
182         mod and rem when second operand is 2 (for parity checks).]
183     13. Changed representation of type Time.time, using a single IntInf.int
184         value counting microseconds.  This considerably simplified the
185         implementation of structure Time.  We now support negative time
186         values; scan and fromString handle signs.
187     14. Functor PrimIO now takes two additional arguments (VectorSlice and
188         ArraySlice).

193    Tag: blume-20030828-intinf
194    Description:
195    
196    This is a major update which comes with a version number bump
197    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
198    and an implementation of IntInf in the Basis.
199    
200    There are a fairly large number of related changes and updates throughout
201    the system:
202    
203    Basis:
204            - Implemented IntInf.
205            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
206            - Added some missing Real64 operations, most notably Real.toLargeInt.
207            - Added FixedInt as a synonym for Int32.
208    
209    compiler:
210            * Added support for a built-in intinf type.
211              - literals
212              - pattern matching
213              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
214              - overloading on literals and operations
215    
216            This required adding a primitive type intinf, some additional
217            primops, and implementations for several non-trivial intinf
218            operations in Core.  (The intinf type is completely abstract
219            to the compiler; all operations get delegated back to the Core.)
220    
221            * Intinf equality is handled by polyequal.  However, the compiler
222            does not print its usual warning in this case (since polyequal
223            is the right thing to do there).
224    
225            * Improved the organization of structure InlineT.
226    
227            * A word about conversion primops:
228            If conversions involving intinf do not cancel out during
229            CPS contract, then the compiler must insert calls to Core functions.
230            Since all core access must be resolved already during the FLINT
231            translate phase, it would be too late a the time of CPS contract
232            to add new Core calls.  For this reason, conversion primops
233            for intinf carry two arguments:  1. the numeric argument that
234            they are supposed to convert, and 2. the Core function that
235            can help with this conversion if necessary.  If CPS contract
236            eliminates a primop, then the associated Core function becomes
237            dead and goes away.  Intinf conversion primops that do not get
238            eliminated by CPS contract get rewritten into calls of their
239            core functions by a separate, new phase.
240    
241    interactive system:
242            - Control.Print.intinfDepth controls max length of intinf constants
243            being printed. (Analogous to Control.Print.stringDepth.)
244            - Cleanup in printutil and pputil: got rid of unused stuff and
245            duplicates; replaced some of the code with code that makes better
246            use of library functionality.
247    
248    CM:
249            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
250            are no longer silent.
251    
252    CKIT:
253            Fixed mismatched uses of Int32 and LargeInt.  I always decided
254            in favor of LargeInt -- which is now the same as IntInf.
255            CKIT-knowledgable people should check whether this is what's
256            intended and otherwise change things back to using Int32 or
257            FixedInt.
258    
259    Throughout the code:
260            Started using IntInf.int literals and built-in operations
261            (e.g., comparison with 0) where this seems appropriate.

268    Description:
269    
270    Merging changes from the mcz-branch development branch into trunk.
271    These changes involve replacement of the emulated old prettyprinter
272    interface with direct use of the SML/NJ Lib PP library, and fixing
273    of a couple of bugs (895, 1186) relating to error messages.  A new
274    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
275    has been added.

281    Description:
282    
283    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
284    
285        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
286    
287    This patch restores SML/NJ's ability to run under win32.  There are a
288    number of changes, including fixes for several bugs that had gone
289    unnoticed until now:
290    
291      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
292        trying to run the win32 version from within cygwin.)
293    
294      - There are a number of simple .bat scripts that substitute for their
295        corresponding Unix shell-scripts.  (See below.)
296    
297      - The internals of ml-build have been modified slightly.  The main
298        difference is that instead of calling ".link-sml" (or link-sml.bat)
299        using OS.Process.system, the ML process delegates this task back
300        to the script.  Otherwise problems arise in mixed environments such
301        as Cygwin where scripts look and work like Unix scripts, but
302        where OS.Process.system cannot run them.
303    
304      - In CM, the srcpath pickler used native pathname syntax -- which
305        is incorrect in the case of cross-compilation.  The new pickle format
306        is independent of platform-specific naming conventions.
307    
308      - Path configuration files (such as lib/pathconfig) can now choose
309        between native and standard syntax.  Placing a line of the form
310    
311            standard!
312    
313        into the file causes all subsequent paths to be interpreted using
314        CM standard pathname syntax (= Unix conventions); a line
315    
316            native!
317    
318        switches back to native style.  This was needed so that
319        path config files can be written portably, see src/system/pathconfig.
320    
321      - Runtime system:
322    
323          - win32-filesys.c:  get_file_time and set_file_time now
324            access modification time, not creation time.
325    
326          - I/O code made aware of new array representation.
327    
328          - Bug fixes in X86.prim.masm.
329    
330       - src/system/makeml made aware of win32. (For use under cygwin
331            and other Unix-environments for windows.)
332    
333       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
334         which caused BinIO.inputAll to fail consistently.
335    
336    .bat scripts:
337    
338       Windows .bat scripts assume that SMLNJ_HOME is defined.
339    
340       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
341         applications (sml, ml-yacc, ml-lex).
342       - ml-build.bat: analogous to ml-build.
343       - config\install.bat:  Analogous to config/install.sh.  This requires
344         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
345         (nmake etc. must be on the path, and vcvars32 must have been run.)
346         Moreover, sources for ml-lex and ml-yacc need to exist under src,
347         and the bootfile hierarchy must have been unpacked under
348         sml.boot.x86-win32.
349         The script is very primitive and does a poor job at error checking.
350         It only installs the base system, ml-lex, and ml-yacc.  No other
351         libraries are being installed (i.e., you get only those that
352         are part of the compiler.)
353       - link-sml.bat:  analogous to .link-sml, but not currently used
354    
355    Unrelated bug fixes:
356    
357      - ml-nlffigen now exports structures ST_* corresponding to incomplete
358        types.
359      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
360        otherwise.)

386    Two changes:
387    
388      1. Added a flag for controlling whether non-exhaustive bindings will
389         be treated as errors (default is false).
390      2. Cleaned up the *entire* source tree so that CMB.make goes through
391         without a single non-exhaustive match- or bind warning.

397    Description:
398    
399    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
400    
401       This mainly affects the quality of error messages.  However, some
402       of the code is now more straightforward than before. (Treatment of
403       the above four constructs in translate.sml is much simpler than
404       the "macro-expansion" that was going on before.  Plus, the mach-
405       compiler no longer gets invoked just to be able to compile an
406       if-expression.)
407    
408    2. The ErrorMsg.Error exception is now caught and absorbed by the
409       interactive loop.

415    Description:
416    
417        Ported the runtime system to cygwin, which uses the unix
418    x86-unix bin files.  Missing/buggy features:
419    
420       o getnetbyname, getnetbyaddr: these functions seem to be missing in
421         the Cygwin library.
422       o Ctrl-C handling may be flaky.
423       o Windows system calls and Windows I/O are not supported.
424    
425       A new set of binfiles is located at:
426    
427         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
428    
429       This is only needed for bootstrapping the cygwin version of smlnj.
430       Other x86 versions can use the existing binfiles.

446    Description:
447    
448    Fixed a bug in Int.rem(x,y) where y is a power of 2 on x86.
449    The arguments to the SUBL instruction were swapped.

455    Description:
456    
457    Fixed a serious bug in the rewrite code for FP spilling/reloading that
458    sent the RA into an infinite loop when floating point registers get
459    spilled.  (Because of this bug, e.g., nucleic stopped compiling between
460    110.37 and 110.38.)
461    There was another set of potential problems related to the handling of
462    MLRISC annotations (but those did not yet cause real problems, apparently).

468    Description:
469    
470    Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
471    This fixes the problem of CM getting confused by files that suddenly
472    change their identity (e.g., by getting unlinked and recreated by some
473    text editor such as vi).  There might be a better/cheaper/cleaner way
474    of doing this, but for now this will have to do.

488    Description:
489    
490    In good old tradition, there has been a slight hiccup so that we have
491    to patch 110.42 after the fact.   The old release tag has been replaced
492    (see below).
493    
494    The change solves a problem with two competing approaches the
495    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
496    each other's way.
497    
498    This change only affects the runtime system code and the installer script.
499    (No new bootfiles.)

513    Description:
514    
515    The mltree operator DIVS must be implemented with an overflow check on
516    the PPC because the hardware indicates divide-by-zero using "overflow" as
517    well.

523    Description:
524    
525    Sml now senses the SMLNJ_HOME environment variable.  If this is set,
526    then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
527    CM_PATHCONFIG is also set), the path configuration file is assumed
528    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
529    the entire tree to some other place and everything will "just work".
530    
531    (Companion commands such as ml-build and ml-makedepend also sense this
532    variable.)
