20    
21    As per request by Adam Chlipala <adam@hcoop.net>, extended various
22    export lists in compiler-related .cm-files.

27    Tag: blume-20040511-allsource
28    Description:
29    
30    The installer now honors the "src-smlnj" target again, although its meaning
31    has changed from "all sources required for the compiler" to "all sources
32    the installer knows about".  In other words, if you enable "src-smlnj"
33    in the "targets" file, then the installer will pull in sources for
34    everything.  (Notice that this refers to source code only.  Compiled
35    code is still only installed for modules that were requested explicitly
36    or which are required for other modules that were requested explicitly.)

42    Description:
43    
44    Fixed IEEEReal.scan (and .fromString) so that if there is an overflow
45    in the exponent calculation we get INF or ZERO (depending on the mantissa
46    and the sign of the exponent).

69    Tag: leunga-20040319-cygwin-nlffi
70    Description:
71    
72    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
73    of SML/NJ.  The problem is that
74    
75       lib = dlopen(NULL, ...)
76       f   = dlsym(lib, "malloc");
77    
78    does not work on Windows unless we explicitly export symbols
79    such as 'malloc' during linking.  We fixed this by explicitly
80    exporting the required symbols with the magic gcc incantation:
81    
82        -Wl,--export-all cygwin.def
83    
84    where cygwin.def is a file containing all the symbols that
85    we wish to export.
86    
87    I suspect this is a Windows problem and we'll have to
88    do the same (somehow with windows compilers) when
89    we build the native win32 version with the system
90    calls LoadLibrary/GetProcAddress.

105    Description:
106    
107    Fixed problem with installer script (unix only) where bin/ml-yacc and
108    friends pointed (via symlinks) to absolute locations instead of just
109    .run-sml.  This was reported by Vesa A Norrman.

157    Tag: blume-20031104-move-libraries
158    Description:
159    
160    Eliminated the "dont_move_libraries" directive in config/targets.
161    (The mechanism was broken and could not be fixed easily.  Moreover,
162    there does not seem to be any reason not to move all libraries into
163    lib during installation.  I originally implemented this directive as a
164    backward-compatibility feature when I first introduced the new CM.
165    Now that things have been stable for a long time and going back to the
166    old CM is not an option, there is no reason to keep it around.)

215    Tag: blume-20030926-ppautoload
216    Description:
217    
218    I modified the read-eval-print loop so that the autoloader gets
219    invoked whenever the prettyprinter tries to look up a symbol that
220    is not currently defined in the toplevel environment but which
221    appears in CM's autoload registry.  As a result, we see far fewer of
222    those ?.Foo.Bar.xxx names in the prettyprinter's output.
223    
224    In addition to this I tried to clean up some pieces of the Basis
225    implementation (e.g., Socket, Word8Array) in order to prevent other
226    instances of these ?.Foo.Bar.xxx names from being printed.
227    
228    The mechanism that picks names for types still needs some work, though.
229    (Right now it seems that if there is a type A.t which is defined to
230    be B.u, but B is unavailable at toplevel, then A.t gets printed as
231    "?.B.u" although the perhaps more sensible solution would be to use
232    "A.t" in this case.  In other words, the prettyprinter should follow
233    a chain of DEFtycs not farther than there are corresponding toplevel
234    names in the current environment.)

239    Tag: blume-20030924-installer
240    Description:
241    
242    Another installer tweak:  All the ML code for the installer is now
243    compiled during CMB.make and put into a little library called
244    $smlnj/installer.cm.  The installation then simply invokes
245    
246       sml -m $smlnj/installer.cm
247    
248    and everything happens automagically.
249    
250    Win32:  ML code senses value of environment variable SMLNJ_HOME.
251    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
252            and BINDIR.
253    
254    The new scheme guarantees that the ML code responsible for the installation
255    is in sync with the APIs of the main system.  Also, the installer is
256    somewhat faster because the installer script is precompiled.

261    Tag: blume-20030924-synsock
262    Description:
263    
264    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
265    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
266    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
267    implementations of non-blocking operations from CML's Socket
268    structure.

273    Tag: blume-20030924-sockets
274    Description:
275    
276    1. Fixed SOCKET API and implementation to match Basis spec.
277       This required changing the internal representation of sockets to one
278       that remembers (for each socket file descriptor) whether it is currently
279       blocking or non-blocking.  This state is maintained lazily (i.e., a system
280       call is made only if the state actually needs to change).
281    
282    2. OS-specific details of sockets were moved into separate files, thus
283       making it possible to unify the bulk of the socket implementations
284       between Unix and Win32.
285    
286    3. CML's socket API changed accordingly.
287       (Note that we need to remove non-blocking functions from this API
288       since they are redundant in the case of CML!)
289    
290    4. CML's socket implementation now makes use of non-blocking functions
291       provided by Basis, thus removing all OS-dependent code from this part
292       of CML.
293    
294    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

311    Description:
312    
313    1. new-install.sh -> install.sh
314    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
315    3. tweaked installer so that another name instead of .cm can be chosen
316       at install time (by setting the CM_DIR_ARC environment variable
317       during installation); once installation is complete, the name is
318       fixed

337    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
338       this seems to be controversial at the moment) and used those in
339       Posix.ProcEnv.times.
340    
341    2. Added Time.{from,to}Nanoseconds to Time.
342    
343    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
344       For example, fromLargeInt never needs to look at more than 3 "big
345       digits" to get its 53 bits of precision.

351    Description:
352    
353    Added an entry to the primitive environment
354    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and

356    
357    Removed some of the "magic" constants in real64.sml and replaced them
358    with code that generates these values from their corresponding
359    integer counterparts.
360    
361    Made all(?) the slice-related changes to the Basis and made everything
362    compile again...
