20    
21    Minor bugfix in config/libinstall (set anchor with path to
22    standalone tool after installing it, otherwise libraries that
23    need ml-lex or ml-yacc won't compile the first time the installer
24    runs).

50    Description:
51    
52    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
53    Modified config/install.bat to take advantage of it.  Also modified
54    config/install.sh (and called it config/new-install.sh) to take advantage
55    of it on Unix systems.  (The SML code is (supposed to be) platform-
56    independent.)
57    
58    The installer can now install everything under Win32
59    as well as under *nix as long as it compiles.
60    
61    Other changes:
62    
63      - made CML compile again under Win32
64      - made eXene compile under Win32 (by providing a fake structure UnixSock
65        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
66      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
67        same as type int;  under Win32 it isn't
68      - fixed some slice-related problems in the win32-specific parts of CML
69      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
70        (under Win32, the volume name is case-insensitive, and the
71        OS.Path code compares volume names for equality)

77    Description:
78    
79    Made Win32 version of OS.FileSys.fullPath return current directory
80    when given an empty string.  This is what the spec says, and incidentally,
81    CM depends on it.  (CM otherwise goes into an infinite loop in certain
82    cases when presented with the name of a non-existing .cm file.)

87    Tag: blume-20030905-slices-etc
88    Description:
89    
90      1. Changed interface to vectors and arrays in Basis to match
91         (draft) Basis spec.
92      2. Added signatures and implementations of slices according to
93         Basis spec.
94      3. Edited source code throughout the system to make it compile again
95         under 1. and 2.  (In some cases code had to be added to have it
96         match the new signatures.)
97      4. MLRISC should be backward-compatible: the copies of the originals
98         of files that needed to change under 3. were retained, the .cm files
99         check the compiler version number and use old versions when
100         appropriate.
101      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
102         dirstream -> string option (in accordance with Basis spec).
103      6. When generating code that counts lines, ml-lex used function
104         CharVector.foldli, taking advantage of its old interface.
105         This has been replaced with the corresponding code from
106         CharVectorSlice.  (html-lex must be re-lexed!)
107      7. BitArray in smlnj-lib/Util has been extended/modified to match the
108         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
109      8. Removed temporary additions (fromInternal, toInternal) from the
110         (now obsolete) IntInf in smlnj-lib/Util.
111      9. Cleaned up structure Byte.
112     10. Added localOffset, scan, and fromString to Date (according to spec).
113         Cleaned/corrected implementation of Date.
114         (Still need to check for correctness; implement better canonicalizeDate.)
115     11. Added "scan" to signature IEEE_REAL.
116     12. Some improvements to IntInf [in particular: efficiency-hack for
117         mod and rem when second operand is 2 (for parity checks).]
118     13. Changed representation of type Time.time, using a single IntInf.int
119         value counting microseconds.  This considerably simplified the
120         implementation of structure Time.  We now support negative time
121         values; scan and fromString handle signs.
122     14. Functor PrimIO now takes two additional arguments (VectorSlice and
123         ArraySlice).

128    Tag: blume-20030828-intinf
129    Description:
130    
131    This is a major update which comes with a version number bump
132    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
133    and an implementation of IntInf in the Basis.
134    
135    There are a fairly large number of related changes and updates throughout
136    the system:
137    
138    Basis:
139            - Implemented IntInf.
140            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
141            - Added some missing Real64 operations, most notably Real.toLargeInt.
142            - Added FixedInt as a synonym for Int32.
143    
144    compiler:
145            * Added support for a built-in intinf type.
146              - literals
147              - pattern matching
148              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
149              - overloading on literals and operations
150    
151            This required adding a primitive type intinf, some additional
152            primops, and implementations for several non-trivial intinf
153            operations in Core.  (The intinf type is completely abstract
154            to the compiler; all operations get delegated back to the Core.)
155    
156            * Intinf equality is handled by polyequal.  However, the compiler
157            does not print its usual warning in this case (since polyequal
158            is the right thing to do there).
159    
160            * Improved the organization of structure InlineT.
161    
162            * A word about conversion primops:
163            If conversions involving intinf do not cancel out during
164            CPS contract, then the compiler must insert calls to Core functions.
165            Since all core access must be resolved already during the FLINT
166            translate phase, it would be too late a the time of CPS contract
167            to add new Core calls.  For this reason, conversion primops
168            for intinf carry two arguments:  1. the numeric argument that
169            they are supposed to convert, and 2. the Core function that
170            can help with this conversion if necessary.  If CPS contract
171            eliminates a primop, then the associated Core function becomes
172            dead and goes away.  Intinf conversion primops that do not get
173            eliminated by CPS contract get rewritten into calls of their
174            core functions by a separate, new phase.
175    
176    interactive system:
177            - Control.Print.intinfDepth controls max length of intinf constants
178            being printed. (Analogous to Control.Print.stringDepth.)
179            - Cleanup in printutil and pputil: got rid of unused stuff and
180            duplicates; replaced some of the code with code that makes better
181            use of library functionality.
182    
183    CM:
184            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
185            are no longer silent.
186    
187    CKIT:
188            Fixed mismatched uses of Int32 and LargeInt.  I always decided
189            in favor of LargeInt -- which is now the same as IntInf.
190            CKIT-knowledgable people should check whether this is what's
191            intended and otherwise change things back to using Int32 or
192            FixedInt.
193    
194    Throughout the code:
195            Started using IntInf.int literals and built-in operations
196            (e.g., comparison with 0) where this seems appropriate.
197

203    Description:
204    
205    Merging changes from the mcz-branch development branch into trunk.
206    These changes involve replacement of the emulated old prettyprinter
207    interface with direct use of the SML/NJ Lib PP library, and fixing
208    of a couple of bugs (895, 1186) relating to error messages.  A new
209    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
210    has been added.

216    Description:
217    
218    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
219    
220        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
221    
222    This patch restores SML/NJ's ability to run under win32.  There are a
223    number of changes, including fixes for several bugs that had gone
224    unnoticed until now:
225    
226      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
227        trying to run the win32 version from within cygwin.)
228    
229      - There are a number of simple .bat scripts that substitute for their
230        corresponding Unix shell-scripts.  (See below.)
231    
232      - The internals of ml-build have been modified slightly.  The main
233        difference is that instead of calling ".link-sml" (or link-sml.bat)
234        using OS.Process.system, the ML process delegates this task back
235        to the script.  Otherwise problems arise in mixed environments such
236        as Cygwin where scripts look and work like Unix scripts, but
237        where OS.Process.system cannot run them.
238    
239      - In CM, the srcpath pickler used native pathname syntax -- which
240        is incorrect in the case of cross-compilation.  The new pickle format
241        is independent of platform-specific naming conventions.
242    
243      - Path configuration files (such as lib/pathconfig) can now choose
244        between native and standard syntax.  Placing a line of the form
245    
246            standard!
247    
248        into the file causes all subsequent paths to be interpreted using
249        CM standard pathname syntax (= Unix conventions); a line
250    
251            native!
252    
253        switches back to native style.  This was needed so that
254        path config files can be written portably, see src/system/pathconfig.
255    
256      - Runtime system:
257    
258          - win32-filesys.c:  get_file_time and set_file_time now
259            access modification time, not creation time.
260    
261          - I/O code made aware of new array representation.
262    
263          - Bug fixes in X86.prim.masm.
264    
265       - src/system/makeml made aware of win32. (For use under cygwin
266            and other Unix-environments for windows.)
267    
268       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
269         which caused BinIO.inputAll to fail consistently.
270    
271    .bat scripts:
272    
273       Windows .bat scripts assume that SMLNJ_HOME is defined.
274    
275       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
276         applications (sml, ml-yacc, ml-lex).
277       - ml-build.bat: analogous to ml-build.
278       - config\install.bat:  Analogous to config/install.sh.  This requires
279         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
280         (nmake etc. must be on the path, and vcvars32 must have been run.)
281         Moreover, sources for ml-lex and ml-yacc need to exist under src,
282         and the bootfile hierarchy must have been unpacked under
283         sml.boot.x86-win32.
284         The script is very primitive and does a poor job at error checking.
285         It only installs the base system, ml-lex, and ml-yacc.  No other
286         libraries are being installed (i.e., you get only those that
287         are part of the compiler.)
288       - link-sml.bat:  analogous to .link-sml, but not currently used
289    
290    Unrelated bug fixes:
291    
292      - ml-nlffigen now exports structures ST_* corresponding to incomplete
293        types.
294      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
295        otherwise.)

321    Two changes:
322    
323      1. Added a flag for controlling whether non-exhaustive bindings will
324         be treated as errors (default is false).
325      2. Cleaned up the *entire* source tree so that CMB.make goes through
326         without a single non-exhaustive match- or bind warning.

332    Description:
333    
334    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
335    
336       This mainly affects the quality of error messages.  However, some
337       of the code is now more straightforward than before. (Treatment of
338       the above four constructs in translate.sml is much simpler than
339       the "macro-expansion" that was going on before.  Plus, the mach-
340       compiler no longer gets invoked just to be able to compile an
341       if-expression.)
342    
343    2. The ErrorMsg.Error exception is now caught and absorbed by the
344       interactive loop.

350    Description:
351    
352        Ported the runtime system to cygwin, which uses the unix
353    x86-unix bin files.  Missing/buggy features:
354    
355       o getnetbyname, getnetbyaddr: these functions seem to be missing in
356         the Cygwin library.
357       o Ctrl-C handling may be flaky.
358       o Windows system calls and Windows I/O are not supported.
359    
360       A new set of binfiles is located at:
361    
362         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
363    
364       This is only needed for bootstrapping the cygwin version of smlnj.
365       Other x86 versions can use the existing binfiles.

391    
392    Fixed a serious bug in the rewrite code for FP spilling/reloading that
393    sent the RA into an infinite loop when floating point registers get
394    spilled.  (Because of this bug, e.g., nucleic stopped compiling between
395    110.37 and 110.38.)
396    There was another set of potential problems related to the handling of
397    MLRISC annotations (but those did not yet cause real problems, apparently).

404    
405    Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
406    This fixes the problem of CM getting confused by files that suddenly
407    change their identity (e.g., by getting unlinked and recreated by some
408    text editor such as vi).  There might be a better/cheaper/cleaner way
409    of doing this, but for now this will have to do.
