18    Tag: leunga-20040319-cygwin-nlffi
19    Description:
20    
21    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
22    of SML/NJ.  The problem is that
23    
24       lib = dlopen(NULL, ...)
25       f   = dlsym(lib, "malloc");
26    
27    does not work on Windows unless we explicitly export symbols
28    such as 'malloc' during linking.  We fixed this by explicitly
29    exporting the required symbols with the magic gcc incantation:
30    
31        -Wl,--export-all cygwin.def
32    
33    where cygwin.def is a file containing all the symbols that
34    we wish to export.
35    
36    I suspect this is a Windows problem and we'll have to
37    do the same (somehow with windows compilers) when
38    we build the native win32 version with the system
39    calls LoadLibrary/GetProcAddress.

46    
47    Fixed problem with IntInf.fmt (sign would show up on the right instead
48    of on the left for BIN, OCT, and HEX).

54    Description:
55    
56    Fixed problem with installer script (unix only) where bin/ml-yacc and
57    friends pointed (via symlinks) to absolute locations instead of just
58    .run-sml.  This was reported by Vesa A Norrman.

106    Tag: blume-20031104-move-libraries
107    Description:
108    
109    Eliminated the "dont_move_libraries" directive in config/targets.
110    (The mechanism was broken and could not be fixed easily.  Moreover,
111    there does not seem to be any reason not to move all libraries into
112    lib during installation.  I originally implemented this directive as a
113    backward-compatibility feature when I first introduced the new CM.
114    Now that things have been stable for a long time and going back to the
115    old CM is not an option, there is no reason to keep it around.)

164    Tag: blume-20030926-ppautoload
165    Description:
166    
167    I modified the read-eval-print loop so that the autoloader gets
168    invoked whenever the prettyprinter tries to look up a symbol that
169    is not currently defined in the toplevel environment but which
170    appears in CM's autoload registry.  As a result, we see far fewer of
171    those ?.Foo.Bar.xxx names in the prettyprinter's output.
172    
173    In addition to this I tried to clean up some pieces of the Basis
174    implementation (e.g., Socket, Word8Array) in order to prevent other
175    instances of these ?.Foo.Bar.xxx names from being printed.
176    
177    The mechanism that picks names for types still needs some work, though.
178    (Right now it seems that if there is a type A.t which is defined to
179    be B.u, but B is unavailable at toplevel, then A.t gets printed as
180    "?.B.u" although the perhaps more sensible solution would be to use
181    "A.t" in this case.  In other words, the prettyprinter should follow
182    a chain of DEFtycs not farther than there are corresponding toplevel
183    names in the current environment.)

188    Tag: blume-20030924-installer
189    Description:
190    
191    Another installer tweak:  All the ML code for the installer is now
192    compiled during CMB.make and put into a little library called
193    $smlnj/installer.cm.  The installation then simply invokes
194    
195       sml -m $smlnj/installer.cm
196    
197    and everything happens automagically.
198    
199    Win32:  ML code senses value of environment variable SMLNJ_HOME.
200    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
201            and BINDIR.
202    
203    The new scheme guarantees that the ML code responsible for the installation
204    is in sync with the APIs of the main system.  Also, the installer is
205    somewhat faster because the installer script is precompiled.

210    Tag: blume-20030924-synsock
211    Description:
212    
213    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
214    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
215    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
216    implementations of non-blocking operations from CML's Socket
217    structure.

222    Tag: blume-20030924-sockets
223    Description:
224    
225    1. Fixed SOCKET API and implementation to match Basis spec.
226       This required changing the internal representation of sockets to one
227       that remembers (for each socket file descriptor) whether it is currently
228       blocking or non-blocking.  This state is maintained lazily (i.e., a system
229       call is made only if the state actually needs to change).
230    
231    2. OS-specific details of sockets were moved into separate files, thus
232       making it possible to unify the bulk of the socket implementations
233       between Unix and Win32.
234    
235    3. CML's socket API changed accordingly.
236       (Note that we need to remove non-blocking functions from this API
237       since they are redundant in the case of CML!)
238    
239    4. CML's socket implementation now makes use of non-blocking functions
240       provided by Basis, thus removing all OS-dependent code from this part
241       of CML.
242    
243    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

259    Tag: blume-20030919-cmdir
260    Description:
261    
262    1. new-install.sh -> install.sh
263    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
264    3. tweaked installer so that another name instead of .cm can be chosen
265       at install time (by setting the CM_DIR_ARC environment variable
266       during installation); once installation is complete, the name is
267       fixed

284    Description:
285    
286    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
287       this seems to be controversial at the moment) and used those in
288       Posix.ProcEnv.times.
289    
290    2. Added Time.{from,to}Nanoseconds to Time.
291    
292    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
293       For example, fromLargeInt never needs to look at more than 3 "big
294       digits" to get its 53 bits of precision.

300    Description:
301    
302    Added an entry to the primitive environment
303    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
304    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
305    
306    Removed some of the "magic" constants in real64.sml and replaced them
307    with code that generates these values from their corresponding
308    integer counterparts.
309    
310    Made all(?) the slice-related changes to the Basis and made everything
311    compile again...
