30    Description:
31    
32    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
33       this seems to be controversial at the moment) and used those in
34       Posix.ProcEnv.times.
35    
36    2. Added Time.{from,to}Nanoseconds to Time.
37    
38    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
39       For example, fromLargeInt never needs to look at more than 3 "big
40       digits" to get its 53 bits of precision.

46    Description:
47    
48    Added an entry to the primitive environment
49    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
50    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
51    
52    Removed some of the "magic" constants in real64.sml and replaced them
53    with code that generates these values from their corresponding
54    integer counterparts.
55    
56    Made all(?) the slice-related changes to the Basis and made everything
57    compile again...

101    Tag: blume-20030909-installer
102    Description:
103    
104    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
105    Modified config/install.bat to take advantage of it.  Also modified
106    config/install.sh (and called it config/new-install.sh) to take advantage
107    of it on Unix systems.  (The SML code is (supposed to be) platform-
108    independent.)
109    
110    The installer can now install everything under Win32
111    as well as under *nix as long as it compiles.
112    
113    Other changes:
114    
115      - made CML compile again under Win32
116      - made eXene compile under Win32 (by providing a fake structure UnixSock
117        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
118      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
119        same as type int;  under Win32 it isn't
120      - fixed some slice-related problems in the win32-specific parts of CML
121      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
122        (under Win32, the volume name is case-insensitive, and the
123        OS.Path code compares volume names for equality)

129    Description:
130    
131    Made Win32 version of OS.FileSys.fullPath return current directory
132    when given an empty string.  This is what the spec says, and incidentally,
133    CM depends on it.  (CM otherwise goes into an infinite loop in certain
134    cases when presented with the name of a non-existing .cm file.)

139    Tag: blume-20030905-slices-etc
140    Description:
141    
142      1. Changed interface to vectors and arrays in Basis to match
143         (draft) Basis spec.
144      2. Added signatures and implementations of slices according to
145         Basis spec.
146      3. Edited source code throughout the system to make it compile again
147         under 1. and 2.  (In some cases code had to be added to have it
148         match the new signatures.)
149      4. MLRISC should be backward-compatible: the copies of the originals
150         of files that needed to change under 3. were retained, the .cm files
151         check the compiler version number and use old versions when
152         appropriate.
153      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
154         dirstream -> string option (in accordance with Basis spec).
155      6. When generating code that counts lines, ml-lex used function
156         CharVector.foldli, taking advantage of its old interface.
157         This has been replaced with the corresponding code from
158         CharVectorSlice.  (html-lex must be re-lexed!)
159      7. BitArray in smlnj-lib/Util has been extended/modified to match the
160         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
161      8. Removed temporary additions (fromInternal, toInternal) from the
162         (now obsolete) IntInf in smlnj-lib/Util.
163      9. Cleaned up structure Byte.
164     10. Added localOffset, scan, and fromString to Date (according to spec).
165         Cleaned/corrected implementation of Date.
166         (Still need to check for correctness; implement better canonicalizeDate.)
167     11. Added "scan" to signature IEEE_REAL.
168     12. Some improvements to IntInf [in particular: efficiency-hack for
169         mod and rem when second operand is 2 (for parity checks).]
170     13. Changed representation of type Time.time, using a single IntInf.int
171         value counting microseconds.  This considerably simplified the
172         implementation of structure Time.  We now support negative time
173         values; scan and fromString handle signs.
174     14. Functor PrimIO now takes two additional arguments (VectorSlice and
175         ArraySlice).

180    Tag: blume-20030828-intinf
181    Description:
182    
183    This is a major update which comes with a version number bump
184    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
185    and an implementation of IntInf in the Basis.
186    
187    There are a fairly large number of related changes and updates throughout
188    the system:
189    
190    Basis:
191            - Implemented IntInf.
192            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
193            - Added some missing Real64 operations, most notably Real.toLargeInt.
194            - Added FixedInt as a synonym for Int32.
195    
196    compiler:
197            * Added support for a built-in intinf type.
198              - literals
199              - pattern matching
200              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
201              - overloading on literals and operations
202    
203            This required adding a primitive type intinf, some additional
204            primops, and implementations for several non-trivial intinf
205            operations in Core.  (The intinf type is completely abstract
206            to the compiler; all operations get delegated back to the Core.)
207    
208            * Intinf equality is handled by polyequal.  However, the compiler
209            does not print its usual warning in this case (since polyequal
210            is the right thing to do there).
211    
212            * Improved the organization of structure InlineT.
213    
214            * A word about conversion primops:
215            If conversions involving intinf do not cancel out during
216            CPS contract, then the compiler must insert calls to Core functions.
217            Since all core access must be resolved already during the FLINT
218            translate phase, it would be too late a the time of CPS contract
219            to add new Core calls.  For this reason, conversion primops
220            for intinf carry two arguments:  1. the numeric argument that
221            they are supposed to convert, and 2. the Core function that
222            can help with this conversion if necessary.  If CPS contract
223            eliminates a primop, then the associated Core function becomes
224            dead and goes away.  Intinf conversion primops that do not get
225            eliminated by CPS contract get rewritten into calls of their
226            core functions by a separate, new phase.
227    
228    interactive system:
229            - Control.Print.intinfDepth controls max length of intinf constants
230            being printed. (Analogous to Control.Print.stringDepth.)
231            - Cleanup in printutil and pputil: got rid of unused stuff and
232            duplicates; replaced some of the code with code that makes better
233            use of library functionality.
234    
235    CM:
236            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
237            are no longer silent.
238    
239    CKIT:
240            Fixed mismatched uses of Int32 and LargeInt.  I always decided
241            in favor of LargeInt -- which is now the same as IntInf.
242            CKIT-knowledgable people should check whether this is what's
243            intended and otherwise change things back to using Int32 or
244            FixedInt.
245    
246    Throughout the code:
247            Started using IntInf.int literals and built-in operations
248            (e.g., comparison with 0) where this seems appropriate.

255    Description:
256    
257    Merging changes from the mcz-branch development branch into trunk.
258    These changes involve replacement of the emulated old prettyprinter
259    interface with direct use of the SML/NJ Lib PP library, and fixing
260    of a couple of bugs (895, 1186) relating to error messages.  A new
261    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
262    has been added.

268    Description:
269    
270    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
271    
272        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
273    
274    This patch restores SML/NJ's ability to run under win32.  There are a
275    number of changes, including fixes for several bugs that had gone
276    unnoticed until now:
277    
278      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
279        trying to run the win32 version from within cygwin.)
280    
281      - There are a number of simple .bat scripts that substitute for their
282        corresponding Unix shell-scripts.  (See below.)
283    
284      - The internals of ml-build have been modified slightly.  The main
285        difference is that instead of calling ".link-sml" (or link-sml.bat)
286        using OS.Process.system, the ML process delegates this task back
287        to the script.  Otherwise problems arise in mixed environments such
288        as Cygwin where scripts look and work like Unix scripts, but
289        where OS.Process.system cannot run them.
290    
291      - In CM, the srcpath pickler used native pathname syntax -- which
292        is incorrect in the case of cross-compilation.  The new pickle format
293        is independent of platform-specific naming conventions.
294    
295      - Path configuration files (such as lib/pathconfig) can now choose
296        between native and standard syntax.  Placing a line of the form
297    
298            standard!
299    
300        into the file causes all subsequent paths to be interpreted using
301        CM standard pathname syntax (= Unix conventions); a line
302    
303            native!
304    
305        switches back to native style.  This was needed so that
306        path config files can be written portably, see src/system/pathconfig.
307    
308      - Runtime system:
309    
310          - win32-filesys.c:  get_file_time and set_file_time now
311            access modification time, not creation time.
312    
313          - I/O code made aware of new array representation.
314    
315          - Bug fixes in X86.prim.masm.
316    
317       - src/system/makeml made aware of win32. (For use under cygwin
318            and other Unix-environments for windows.)
319    
320       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
321         which caused BinIO.inputAll to fail consistently.
322    
323    .bat scripts:
324    
325       Windows .bat scripts assume that SMLNJ_HOME is defined.
326    
327       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
328         applications (sml, ml-yacc, ml-lex).
329       - ml-build.bat: analogous to ml-build.
330       - config\install.bat:  Analogous to config/install.sh.  This requires
331         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
332         (nmake etc. must be on the path, and vcvars32 must have been run.)
333         Moreover, sources for ml-lex and ml-yacc need to exist under src,
334         and the bootfile hierarchy must have been unpacked under
335         sml.boot.x86-win32.
336         The script is very primitive and does a poor job at error checking.
337         It only installs the base system, ml-lex, and ml-yacc.  No other
338         libraries are being installed (i.e., you get only those that
339         are part of the compiler.)
340       - link-sml.bat:  analogous to .link-sml, but not currently used
341    
342    Unrelated bug fixes:
343    
344      - ml-nlffigen now exports structures ST_* corresponding to incomplete
345        types.
346      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
347        otherwise.)

377      2. Cleaned up the *entire* source tree so that CMB.make goes through
378         without a single non-exhaustive match- or bind warning.

384    Description:
385    
386    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
387    
388       This mainly affects the quality of error messages.  However, some
389       of the code is now more straightforward than before. (Treatment of
390       the above four constructs in translate.sml is much simpler than
391       the "macro-expansion" that was going on before.  Plus, the mach-
392       compiler no longer gets invoked just to be able to compile an
393       if-expression.)
394    
395    2. The ErrorMsg.Error exception is now caught and absorbed by the
396       interactive loop.

402    Description:
403    
404        Ported the runtime system to cygwin, which uses the unix
405    x86-unix bin files.  Missing/buggy features:
406    
407       o getnetbyname, getnetbyaddr: these functions seem to be missing in
408         the Cygwin library.
409       o Ctrl-C handling may be flaky.
410       o Windows system calls and Windows I/O are not supported.
411    
412       A new set of binfiles is located at:
413    
414         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
415    
416       This is only needed for bootstrapping the cygwin version of smlnj.
417       Other x86 versions can use the existing binfiles.
