19    Description:
20    
21    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
22    Modified config/install.bat to take advantage of it.  Also modified
23    config/install.sh (and called it config/new-install.sh) to take advantage
24    of it on Unix systems.  (The SML code is (supposed to be) platform-
25    independent.)
26    
27    The installer can now install everything under Win32
28    as well as under *nix as long as it compiles.
29    
30    Other changes:
31    
32      - made CML compile again under Win32
33      - made eXene compile under Win32 (by providing a fake structure UnixSock
34        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
35      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
36        same as type int;  under Win32 it isn't
37      - fixed some slice-related problems in the win32-specific parts of CML
38      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
39        (under Win32, the volume name is case-insensitive, and the
40        OS.Path code compares volume names for equality)

46    Description:
47    
48    Made Win32 version of OS.FileSys.fullPath return current directory
49    when given an empty string.  This is what the spec says, and incidentally,
50    CM depends on it.  (CM otherwise goes into an infinite loop in certain
51    cases when presented with the name of a non-existing .cm file.)

56    Tag: blume-20030905-slices-etc
57    Description:
58    
59      1. Changed interface to vectors and arrays in Basis to match
60         (draft) Basis spec.
61      2. Added signatures and implementations of slices according to
62         Basis spec.
63      3. Edited source code throughout the system to make it compile again
64         under 1. and 2.  (In some cases code had to be added to have it
65         match the new signatures.)
66      4. MLRISC should be backward-compatible: the copies of the originals
67         of files that needed to change under 3. were retained, the .cm files
68         check the compiler version number and use old versions when
69         appropriate.
70      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
71         dirstream -> string option (in accordance with Basis spec).
72      6. When generating code that counts lines, ml-lex used function
73         CharVector.foldli, taking advantage of its old interface.
74         This has been replaced with the corresponding code from
75         CharVectorSlice.  (html-lex must be re-lexed!)
76      7. BitArray in smlnj-lib/Util has been extended/modified to match the
77         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
78      8. Removed temporary additions (fromInternal, toInternal) from the
79         (now obsolete) IntInf in smlnj-lib/Util.
80      9. Cleaned up structure Byte.
81     10. Added localOffset, scan, and fromString to Date (according to spec).
82         Cleaned/corrected implementation of Date.
83         (Still need to check for correctness; implement better canonicalizeDate.)
84     11. Added "scan" to signature IEEE_REAL.
85     12. Some improvements to IntInf [in particular: efficiency-hack for
86         mod and rem when second operand is 2 (for parity checks).]
87     13. Changed representation of type Time.time, using a single IntInf.int
88         value counting microseconds.  This considerably simplified the
89         implementation of structure Time.  We now support negative time
90         values; scan and fromString handle signs.
91     14. Functor PrimIO now takes two additional arguments (VectorSlice and
92         ArraySlice).

97    Tag: blume-20030828-intinf
98    Description:
99    
100    This is a major update which comes with a version number bump
101    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
102    and an implementation of IntInf in the Basis.
103    
104    There are a fairly large number of related changes and updates throughout
105    the system:
106    
107    Basis:
108            - Implemented IntInf.
109            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
110            - Added some missing Real64 operations, most notably Real.toLargeInt.
111            - Added FixedInt as a synonym for Int32.
112    
113    compiler:
114            * Added support for a built-in intinf type.
115              - literals
116              - pattern matching
117              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
118              - overloading on literals and operations
119    
120            This required adding a primitive type intinf, some additional
121            primops, and implementations for several non-trivial intinf
122            operations in Core.  (The intinf type is completely abstract
123            to the compiler; all operations get delegated back to the Core.)
124    
125            * Intinf equality is handled by polyequal.  However, the compiler
126            does not print its usual warning in this case (since polyequal
127            is the right thing to do there).
128    
129            * Improved the organization of structure InlineT.
130    
131            * A word about conversion primops:
132            If conversions involving intinf do not cancel out during
133            CPS contract, then the compiler must insert calls to Core functions.
134            Since all core access must be resolved already during the FLINT
135            translate phase, it would be too late a the time of CPS contract
136            to add new Core calls.  For this reason, conversion primops
137            for intinf carry two arguments:  1. the numeric argument that
138            they are supposed to convert, and 2. the Core function that
139            can help with this conversion if necessary.  If CPS contract
140            eliminates a primop, then the associated Core function becomes
141            dead and goes away.  Intinf conversion primops that do not get
142            eliminated by CPS contract get rewritten into calls of their
143            core functions by a separate, new phase.
144    
145    interactive system:
146            - Control.Print.intinfDepth controls max length of intinf constants
147            being printed. (Analogous to Control.Print.stringDepth.)
148            - Cleanup in printutil and pputil: got rid of unused stuff and
149            duplicates; replaced some of the code with code that makes better
150            use of library functionality.
151    
152    CM:
153            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
154            are no longer silent.
155    
156    CKIT:
157            Fixed mismatched uses of Int32 and LargeInt.  I always decided
158            in favor of LargeInt -- which is now the same as IntInf.
159            CKIT-knowledgable people should check whether this is what's
160            intended and otherwise change things back to using Int32 or
161            FixedInt.
162    
163    Throughout the code:
164            Started using IntInf.int literals and built-in operations
165            (e.g., comparison with 0) where this seems appropriate.

172    Description:
173    
174    Merging changes from the mcz-branch development branch into trunk.
175    These changes involve replacement of the emulated old prettyprinter
176    interface with direct use of the SML/NJ Lib PP library, and fixing
177    of a couple of bugs (895, 1186) relating to error messages.  A new
178    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
179    has been added.

185    Description:
186    
187    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
188    
189        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
190    
191    This patch restores SML/NJ's ability to run under win32.  There are a
192    number of changes, including fixes for several bugs that had gone
193    unnoticed until now:
194    
195      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
196        trying to run the win32 version from within cygwin.)
197    
198      - There are a number of simple .bat scripts that substitute for their
199        corresponding Unix shell-scripts.  (See below.)
200    
201      - The internals of ml-build have been modified slightly.  The main
202        difference is that instead of calling ".link-sml" (or link-sml.bat)
203        using OS.Process.system, the ML process delegates this task back
204        to the script.  Otherwise problems arise in mixed environments such
205        as Cygwin where scripts look and work like Unix scripts, but
206        where OS.Process.system cannot run them.
207    
208      - In CM, the srcpath pickler used native pathname syntax -- which
209        is incorrect in the case of cross-compilation.  The new pickle format
210        is independent of platform-specific naming conventions.
211    
212      - Path configuration files (such as lib/pathconfig) can now choose
213        between native and standard syntax.  Placing a line of the form
214    
215            standard!
216    
217        into the file causes all subsequent paths to be interpreted using
218        CM standard pathname syntax (= Unix conventions); a line
219    
220            native!
221    
222        switches back to native style.  This was needed so that
223        path config files can be written portably, see src/system/pathconfig.
224    
225      - Runtime system:
226    
227          - win32-filesys.c:  get_file_time and set_file_time now
228            access modification time, not creation time.
229    
230          - I/O code made aware of new array representation.
231    
232          - Bug fixes in X86.prim.masm.
233    
234       - src/system/makeml made aware of win32. (For use under cygwin
235            and other Unix-environments for windows.)
236    
237       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
238         which caused BinIO.inputAll to fail consistently.
239    
240    .bat scripts:
241    
242       Windows .bat scripts assume that SMLNJ_HOME is defined.
243    
244       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
245         applications (sml, ml-yacc, ml-lex).
246       - ml-build.bat: analogous to ml-build.
247       - config\install.bat:  Analogous to config/install.sh.  This requires
248         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
249         (nmake etc. must be on the path, and vcvars32 must have been run.)
250         Moreover, sources for ml-lex and ml-yacc need to exist under src,
251         and the bootfile hierarchy must have been unpacked under
252         sml.boot.x86-win32.
253         The script is very primitive and does a poor job at error checking.
254         It only installs the base system, ml-lex, and ml-yacc.  No other
255         libraries are being installed (i.e., you get only those that
256         are part of the compiler.)
257       - link-sml.bat:  analogous to .link-sml, but not currently used
258    
259    Unrelated bug fixes:
260    
261      - ml-nlffigen now exports structures ST_* corresponding to incomplete
262        types.
263      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
264        otherwise.)
