18		Tag: blume-20031104-move-libraries
19		Description:
20
21		Eliminated the "dont_move_libraries" directive in config/targets.
22		(The mechanism was broken and could not be fixed easily.  Moreover,
23		there does not seem to be any reason not to move all libraries into
24		lib during installation.  I originally implemented this directive as a
25		backward-compatibility feature when I first introduced the new CM.
26		Now that things have been stable for a long time and going back to the
27		old CM is not an option, there is no reason to keep it around.)

76		Tag: blume-20030926-ppautoload
77		Description:
78
79		I modified the read-eval-print loop so that the autoloader gets
80		invoked whenever the prettyprinter tries to look up a symbol that
81		is not currently defined in the toplevel environment but which
82		appears in CM's autoload registry.  As a result, we see far fewer of
83		those ?.Foo.Bar.xxx names in the prettyprinter's output.
84
85		In addition to this I tried to clean up some pieces of the Basis
86		implementation (e.g., Socket, Word8Array) in order to prevent other
87		instances of these ?.Foo.Bar.xxx names from being printed.
88
89		The mechanism that picks names for types still needs some work, though.
90		(Right now it seems that if there is a type A.t which is defined to
91		be B.u, but B is unavailable at toplevel, then A.t gets printed as
92		"?.B.u" although the perhaps more sensible solution would be to use
93		"A.t" in this case.  In other words, the prettyprinter should follow
94		a chain of DEFtycs not farther than there are corresponding toplevel
95		names in the current environment.)

100		Tag: blume-20030924-installer
101		Description:
102
103		Another installer tweak:  All the ML code for the installer is now
104		compiled during CMB.make and put into a little library called
105		$smlnj/installer.cm.  The installation then simply invokes
106
107		sml -m $smlnj/installer.cm
108
109		and everything happens automagically.
110
111		Win32:  ML code senses value of environment variable SMLNJ_HOME.
112		Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
113		and BINDIR.
114
115		The new scheme guarantees that the ML code responsible for the installation
116		is in sync with the APIs of the main system.  Also, the installer is
117		somewhat faster because the installer script is precompiled.

122		Tag: blume-20030924-synsock
123		Description:
124
125		Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
126		but excludes all non-blocking operations.  Defined SOCKET (in Basis)
127		and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
128		implementations of non-blocking operations from CML's Socket
129		structure.

133		Date: 2003/09/24 15:10:05 CDT
134		Tag: blume-20030924-sockets
135		Description:
136
137		1. Fixed SOCKET API and implementation to match Basis spec.
138		This required changing the internal representation of sockets to one
139		that remembers (for each socket file descriptor) whether it is currently
140		blocking or non-blocking.  This state is maintained lazily (i.e., a system
141		call is made only if the state actually needs to change).
142
143		2. OS-specific details of sockets were moved into separate files, thus
144		making it possible to unify the bulk of the socket implementations
145		between Unix and Win32.
146
147		3. CML's socket API changed accordingly.
148		(Note that we need to remove non-blocking functions from this API
149		since they are redundant in the case of CML!)
150
151		4. CML's socket implementation now makes use of non-blocking functions
152		provided by Basis, thus removing all OS-dependent code from this part
153		of CML.
154
155		5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

160		Tag: blume-20030922-110_43_2
161		Description:
162
163		Made a new interim version and bootfiles for developer's bootstrapping
164		convenience.
165
166		110.43.2 -- NEW BOOTFILES

170		Date: 2003/09/19 15:55:00 CDT
171		Tag: blume-20030919-cmdir
172		Description:
173
174		1. new-install.sh -> install.sh
175		2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
176		3. tweaked installer so that another name instead of .cm can be chosen
177		at install time (by setting the CM_DIR_ARC environment variable
178		during installation); once installation is complete, the name is
179		fixed

195		Tag: blume-20030918-misc
196		Description:
197
198		1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
199		this seems to be controversial at the moment) and used those in
200		Posix.ProcEnv.times.
201
202		2. Added Time.{from,to}Nanoseconds to Time.
203
204		3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
205		For example, fromLargeInt never needs to look at more than 3 "big
206		digits" to get its 53 bits of precision.
207

211		Tag: blume-20030917-real32-slices
212		Description:
213
214		Added an entry to the primitive environment
215		(compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
216		added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
217
218		Removed some of the "magic" constants in real64.sml and replaced them
219		with code that generates these values from their corresponding
220		integer counterparts.
221
222		Made all(?) the slice-related changes to the Basis and made everything
223		compile again...
