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

54    Description:
55    
56    Made Win32 version of OS.FileSys.fullPath return current directory
57    when given an empty string.  This is what the spec says, and incidentally,
58    CM depends on it.  (CM otherwise goes into an infinite loop in certain
59    cases when presented with the name of a non-existing .cm file.)

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

106    Description:
107    
108    This is a major update which comes with a version number bump
109    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
110    and an implementation of IntInf in the Basis.
111    
112    There are a fairly large number of related changes and updates throughout
113    the system:
114    
115    Basis:
116            - Implemented IntInf.
117            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
118            - Added some missing Real64 operations, most notably Real.toLargeInt.
119            - Added FixedInt as a synonym for Int32.
120    
121    compiler:
122            * Added support for a built-in intinf type.
123              - literals
124              - pattern matching
125              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
126              - overloading on literals and operations
127    
128            This required adding a primitive type intinf, some additional
129            primops, and implementations for several non-trivial intinf
130            operations in Core.  (The intinf type is completely abstract
131            to the compiler; all operations get delegated back to the Core.)
132    
133            * Intinf equality is handled by polyequal.  However, the compiler
134            does not print its usual warning in this case (since polyequal
135            is the right thing to do there).
136    
137            * Improved the organization of structure InlineT.
138    
139            * A word about conversion primops:
140            If conversions involving intinf do not cancel out during
141            CPS contract, then the compiler must insert calls to Core functions.
142            Since all core access must be resolved already during the FLINT
143            translate phase, it would be too late a the time of CPS contract
144            to add new Core calls.  For this reason, conversion primops
145            for intinf carry two arguments:  1. the numeric argument that
146            they are supposed to convert, and 2. the Core function that
147            can help with this conversion if necessary.  If CPS contract
148            eliminates a primop, then the associated Core function becomes
149            dead and goes away.  Intinf conversion primops that do not get
150            eliminated by CPS contract get rewritten into calls of their
151            core functions by a separate, new phase.
152    
153    interactive system:
154            - Control.Print.intinfDepth controls max length of intinf constants
155            being printed. (Analogous to Control.Print.stringDepth.)
156            - Cleanup in printutil and pputil: got rid of unused stuff and
157            duplicates; replaced some of the code with code that makes better
158            use of library functionality.
159    
160    CM:
161            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
162            are no longer silent.
163    
164    CKIT:
165            Fixed mismatched uses of Int32 and LargeInt.  I always decided
166            in favor of LargeInt -- which is now the same as IntInf.
167            CKIT-knowledgable people should check whether this is what's
168            intended and otherwise change things back to using Int32 or
169            FixedInt.
170    
171    Throughout the code:
172            Started using IntInf.int literals and built-in operations
173            (e.g., comparison with 0) where this seems appropriate.
