28    
29    Minor bugfix in config/libinstall (set anchor with path to
30    standalone tool after installing it, otherwise libraries that
31    need ml-lex or ml-yacc won't compile the first time the installer
32    runs).

58    Description:
59    
60    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
61    Modified config/install.bat to take advantage of it.  Also modified
62    config/install.sh (and called it config/new-install.sh) to take advantage
63    of it on Unix systems.  (The SML code is (supposed to be) platform-
64    independent.)
65    
66    The installer can now install everything under Win32
67    as well as under *nix as long as it compiles.
68    
69    Other changes:
70    
71      - made CML compile again under Win32
72      - made eXene compile under Win32 (by providing a fake structure UnixSock
73        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
74      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
75        same as type int;  under Win32 it isn't
76      - fixed some slice-related problems in the win32-specific parts of CML
77      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
78        (under Win32, the volume name is case-insensitive, and the
79        OS.Path code compares volume names for equality)

85    Description:
86    
87    Made Win32 version of OS.FileSys.fullPath return current directory
88    when given an empty string.  This is what the spec says, and incidentally,
89    CM depends on it.  (CM otherwise goes into an infinite loop in certain
90    cases when presented with the name of a non-existing .cm file.)

95    Tag: blume-20030905-slices-etc
96    Description:
97    
98      1. Changed interface to vectors and arrays in Basis to match
99         (draft) Basis spec.
100      2. Added signatures and implementations of slices according to
101         Basis spec.
102      3. Edited source code throughout the system to make it compile again
103         under 1. and 2.  (In some cases code had to be added to have it
104         match the new signatures.)
105      4. MLRISC should be backward-compatible: the copies of the originals
106         of files that needed to change under 3. were retained, the .cm files
107         check the compiler version number and use old versions when
108         appropriate.
109      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
110         dirstream -> string option (in accordance with Basis spec).
111      6. When generating code that counts lines, ml-lex used function
112         CharVector.foldli, taking advantage of its old interface.
113         This has been replaced with the corresponding code from
114         CharVectorSlice.  (html-lex must be re-lexed!)
115      7. BitArray in smlnj-lib/Util has been extended/modified to match the
116         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
117      8. Removed temporary additions (fromInternal, toInternal) from the
118         (now obsolete) IntInf in smlnj-lib/Util.
119      9. Cleaned up structure Byte.
120     10. Added localOffset, scan, and fromString to Date (according to spec).
121         Cleaned/corrected implementation of Date.
122         (Still need to check for correctness; implement better canonicalizeDate.)
123     11. Added "scan" to signature IEEE_REAL.
124     12. Some improvements to IntInf [in particular: efficiency-hack for
125         mod and rem when second operand is 2 (for parity checks).]
126     13. Changed representation of type Time.time, using a single IntInf.int
127         value counting microseconds.  This considerably simplified the
128         implementation of structure Time.  We now support negative time
129         values; scan and fromString handle signs.
130     14. Functor PrimIO now takes two additional arguments (VectorSlice and
131         ArraySlice).

136    Tag: blume-20030828-intinf
137    Description:
138    
139    This is a major update which comes with a version number bump
140    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
141    and an implementation of IntInf in the Basis.
142    
143    There are a fairly large number of related changes and updates throughout
144    the system:
145    
146    Basis:
147            - Implemented IntInf.
148            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
149            - Added some missing Real64 operations, most notably Real.toLargeInt.
150            - Added FixedInt as a synonym for Int32.
151    
152    compiler:
153            * Added support for a built-in intinf type.
154              - literals
155              - pattern matching
156              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
157              - overloading on literals and operations
158    
159            This required adding a primitive type intinf, some additional
160            primops, and implementations for several non-trivial intinf
161            operations in Core.  (The intinf type is completely abstract
162            to the compiler; all operations get delegated back to the Core.)
163    
164            * Intinf equality is handled by polyequal.  However, the compiler
165            does not print its usual warning in this case (since polyequal
166            is the right thing to do there).
167    
168            * Improved the organization of structure InlineT.
169    
170            * A word about conversion primops:
171            If conversions involving intinf do not cancel out during
172            CPS contract, then the compiler must insert calls to Core functions.
173            Since all core access must be resolved already during the FLINT
174            translate phase, it would be too late a the time of CPS contract
175            to add new Core calls.  For this reason, conversion primops
176            for intinf carry two arguments:  1. the numeric argument that
177            they are supposed to convert, and 2. the Core function that
178            can help with this conversion if necessary.  If CPS contract
179            eliminates a primop, then the associated Core function becomes
180            dead and goes away.  Intinf conversion primops that do not get
181            eliminated by CPS contract get rewritten into calls of their
182            core functions by a separate, new phase.
183    
184    interactive system:
185            - Control.Print.intinfDepth controls max length of intinf constants
186            being printed. (Analogous to Control.Print.stringDepth.)
187            - Cleanup in printutil and pputil: got rid of unused stuff and
188            duplicates; replaced some of the code with code that makes better
189            use of library functionality.
190    
191    CM:
192            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
193            are no longer silent.
194    
195    CKIT:
196            Fixed mismatched uses of Int32 and LargeInt.  I always decided
197            in favor of LargeInt -- which is now the same as IntInf.
198            CKIT-knowledgable people should check whether this is what's
199            intended and otherwise change things back to using Int32 or
200            FixedInt.
201    
202    Throughout the code:
203            Started using IntInf.int literals and built-in operations
204            (e.g., comparison with 0) where this seems appropriate.

211    Description:
212    
213    Merging changes from the mcz-branch development branch into trunk.
214    These changes involve replacement of the emulated old prettyprinter
215    interface with direct use of the SML/NJ Lib PP library, and fixing
216    of a couple of bugs (895, 1186) relating to error messages.  A new
217    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
218    has been added.

224    Description:
225    
226    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
227    
228        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
229    
230    This patch restores SML/NJ's ability to run under win32.  There are a
231    number of changes, including fixes for several bugs that had gone
232    unnoticed until now:
233    
234      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
235        trying to run the win32 version from within cygwin.)
236    
237      - There are a number of simple .bat scripts that substitute for their
238        corresponding Unix shell-scripts.  (See below.)
239    
240      - The internals of ml-build have been modified slightly.  The main
241        difference is that instead of calling ".link-sml" (or link-sml.bat)
242        using OS.Process.system, the ML process delegates this task back
243        to the script.  Otherwise problems arise in mixed environments such
244        as Cygwin where scripts look and work like Unix scripts, but
245        where OS.Process.system cannot run them.
246    
247      - In CM, the srcpath pickler used native pathname syntax -- which
248        is incorrect in the case of cross-compilation.  The new pickle format
249        is independent of platform-specific naming conventions.
250    
251      - Path configuration files (such as lib/pathconfig) can now choose
252        between native and standard syntax.  Placing a line of the form
253    
254            standard!
255    
256        into the file causes all subsequent paths to be interpreted using
257        CM standard pathname syntax (= Unix conventions); a line
258    
259            native!
260    
261        switches back to native style.  This was needed so that
262        path config files can be written portably, see src/system/pathconfig.
263    
264      - Runtime system:
265    
266          - win32-filesys.c:  get_file_time and set_file_time now
267            access modification time, not creation time.
268    
269          - I/O code made aware of new array representation.
270    
271          - Bug fixes in X86.prim.masm.
272    
273       - src/system/makeml made aware of win32. (For use under cygwin
274            and other Unix-environments for windows.)
275    
276       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
277         which caused BinIO.inputAll to fail consistently.
278    
279    .bat scripts:
280    
281       Windows .bat scripts assume that SMLNJ_HOME is defined.
282    
283       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
284         applications (sml, ml-yacc, ml-lex).
285       - ml-build.bat: analogous to ml-build.
286       - config\install.bat:  Analogous to config/install.sh.  This requires
287         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
288         (nmake etc. must be on the path, and vcvars32 must have been run.)
289         Moreover, sources for ml-lex and ml-yacc need to exist under src,
290         and the bootfile hierarchy must have been unpacked under
291         sml.boot.x86-win32.
292         The script is very primitive and does a poor job at error checking.
293         It only installs the base system, ml-lex, and ml-yacc.  No other
294         libraries are being installed (i.e., you get only those that
295         are part of the compiler.)
296       - link-sml.bat:  analogous to .link-sml, but not currently used
297    
298    Unrelated bug fixes:
299    
300      - ml-nlffigen now exports structures ST_* corresponding to incomplete
301        types.
302      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
303        otherwise.)

328    
329    Two changes:
330    
331      1. Added a flag for controlling whether non-exhaustive bindings will
332         be treated as errors (default is false).
333      2. Cleaned up the *entire* source tree so that CMB.make goes through
334         without a single non-exhaustive match- or bind warning.

340    Description:
341    
342    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
343    
344       This mainly affects the quality of error messages.  However, some
345       of the code is now more straightforward than before. (Treatment of
346       the above four constructs in translate.sml is much simpler than
347       the "macro-expansion" that was going on before.  Plus, the mach-
348       compiler no longer gets invoked just to be able to compile an
349       if-expression.)
350    
351    2. The ErrorMsg.Error exception is now caught and absorbed by the
352       interactive loop.

358    Description:
359    
360        Ported the runtime system to cygwin, which uses the unix
361    x86-unix bin files.  Missing/buggy features:
362    
363       o getnetbyname, getnetbyaddr: these functions seem to be missing in
364         the Cygwin library.
365       o Ctrl-C handling may be flaky.
366       o Windows system calls and Windows I/O are not supported.
367    
368       A new set of binfiles is located at:
369    
370         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
371    
372       This is only needed for bootstrapping the cygwin version of smlnj.
373       Other x86 versions can use the existing binfiles.
