45		Tag: blume-20031104-move-libraries
46		Description:
47
48		Eliminated the "dont_move_libraries" directive in config/targets.
49		(The mechanism was broken and could not be fixed easily.  Moreover,
50		there does not seem to be any reason not to move all libraries into
51		lib during installation.  I originally implemented this directive as a
52		backward-compatibility feature when I first introduced the new CM.
53		Now that things have been stable for a long time and going back to the
54		old CM is not an option, there is no reason to keep it around.)

102		Date: 2003/09/26 12:00:00 CDT
103		Tag: blume-20030926-ppautoload
104		Description:
105
106		I modified the read-eval-print loop so that the autoloader gets
107		invoked whenever the prettyprinter tries to look up a symbol that
108		is not currently defined in the toplevel environment but which
109		appears in CM's autoload registry.  As a result, we see far fewer of
110		those ?.Foo.Bar.xxx names in the prettyprinter's output.
111
112		In addition to this I tried to clean up some pieces of the Basis
113		implementation (e.g., Socket, Word8Array) in order to prevent other
114		instances of these ?.Foo.Bar.xxx names from being printed.
115
116		The mechanism that picks names for types still needs some work, though.
117		(Right now it seems that if there is a type A.t which is defined to
118		be B.u, but B is unavailable at toplevel, then A.t gets printed as
119		"?.B.u" although the perhaps more sensible solution would be to use
120		"A.t" in this case.  In other words, the prettyprinter should follow
121		a chain of DEFtycs not farther than there are corresponding toplevel
122		names in the current environment.)

127		Tag: blume-20030924-installer
128		Description:
129
130		Another installer tweak:  All the ML code for the installer is now
131		compiled during CMB.make and put into a little library called
132		$smlnj/installer.cm.  The installation then simply invokes
133
134		sml -m $smlnj/installer.cm
135
136		and everything happens automagically.
137
138		Win32:  ML code senses value of environment variable SMLNJ_HOME.
139		Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
140		and BINDIR.
141
142		The new scheme guarantees that the ML code responsible for the installation
143		is in sync with the APIs of the main system.  Also, the installer is
144		somewhat faster because the installer script is precompiled.

149		Tag: blume-20030924-synsock
150		Description:
151
152		Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
153		but excludes all non-blocking operations.  Defined SOCKET (in Basis)
154		and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
155		implementations of non-blocking operations from CML's Socket
156		structure.

160		Date: 2003/09/24 15:10:05 CDT
161		Tag: blume-20030924-sockets
162		Description:
163
164		1. Fixed SOCKET API and implementation to match Basis spec.
165		This required changing the internal representation of sockets to one
166		that remembers (for each socket file descriptor) whether it is currently
167		blocking or non-blocking.  This state is maintained lazily (i.e., a system
168		call is made only if the state actually needs to change).
169
170		2. OS-specific details of sockets were moved into separate files, thus
171		making it possible to unify the bulk of the socket implementations
172		between Unix and Win32.
173
174		3. CML's socket API changed accordingly.
175		(Note that we need to remove non-blocking functions from this API
176		since they are redundant in the case of CML!)
177
178		4. CML's socket implementation now makes use of non-blocking functions
179		provided by Basis, thus removing all OS-dependent code from this part
180		of CML.
181
182		5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

199		Description:
200
201		1. new-install.sh -> install.sh
202		2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
203		3. tweaked installer so that another name instead of .cm can be chosen
204		at install time (by setting the CM_DIR_ARC environment variable
205		during installation); once installation is complete, the name is
206		fixed

222		Tag: blume-20030918-misc
223		Description:
224
225		1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
226		this seems to be controversial at the moment) and used those in
227		Posix.ProcEnv.times.
228
229		2. Added Time.{from,to}Nanoseconds to Time.
230
231		3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
232		For example, fromLargeInt never needs to look at more than 3 "big
233		digits" to get its 53 bits of precision.

238		Tag: blume-20030917-real32-slices
239		Description:
240
241		Added an entry to the primitive environment
242		(compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
243		added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
244
245		Removed some of the "magic" constants in real64.sml and replaced them
246		with code that generates these values from their corresponding
247		integer counterparts.
248
249		Made all(?) the slice-related changes to the Basis and made everything
250		compile again...

264		Description:
265
266		Minor bugfix in config/libinstall (set anchor with path to
267		standalone tool after installing it, otherwise libraries that
268		need ml-lex or ml-yacc won't compile the first time the installer
269		runs).

293		Date: 2003/09/09 19:20:00 CDT
294		Tag: blume-20030909-installer
295		Description:
296
297		Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
298		Modified config/install.bat to take advantage of it.  Also modified
299		config/install.sh (and called it config/new-install.sh) to take advantage
300		of it on Unix systems.  (The SML code is (supposed to be) platform-
301		independent.)
302
303		The installer can now install everything under Win32
304		as well as under *nix as long as it compiles.
305
306		Other changes:
307
308		- made CML compile again under Win32
309		- made eXene compile under Win32 (by providing a fake structure UnixSock
310		and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
311		- fixed a bug in nowhere: it assumed that type OS.Process.status is the
312		same as type int;  under Win32 it isn't
313		- fixed some slice-related problems in the win32-specific parts of CML
314		- added a functor argument "sameVol" to os-path-fn.sml in the Basis
315		(under Win32, the volume name is case-insensitive, and the
316		OS.Path code compares volume names for equality)

321		Tag: blume-20030908-fullpath
322		Description:
323
324		Made Win32 version of OS.FileSys.fullPath return current directory
325		when given an empty string.  This is what the spec says, and incidentally,
326		CM depends on it.  (CM otherwise goes into an infinite loop in certain
327		cases when presented with the name of a non-existing .cm file.)

331		Date: 2003/09/04 16:30:00 CDT
332		Tag: blume-20030905-slices-etc
333		Description:
334
335		1. Changed interface to vectors and arrays in Basis to match
336		(draft) Basis spec.
337		2. Added signatures and implementations of slices according to
338		Basis spec.
339		3. Edited source code throughout the system to make it compile again
340		under 1. and 2.  (In some cases code had to be added to have it
341		match the new signatures.)
342		4. MLRISC should be backward-compatible: the copies of the originals
343		of files that needed to change under 3. were retained, the .cm files
344		check the compiler version number and use old versions when
345		appropriate.
346		5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
347		dirstream -> string option (in accordance with Basis spec).
348		6. When generating code that counts lines, ml-lex used function
349		CharVector.foldli, taking advantage of its old interface.
350		This has been replaced with the corresponding code from
351		CharVectorSlice.  (html-lex must be re-lexed!)
352		7. BitArray in smlnj-lib/Util has been extended/modified to match the
353		new MONO_ARRAY signature.  (Do we need BitArraySlice?)
354		8. Removed temporary additions (fromInternal, toInternal) from the
355		(now obsolete) IntInf in smlnj-lib/Util.
356		9. Cleaned up structure Byte.
357		10. Added localOffset, scan, and fromString to Date (according to spec).
358		Cleaned/corrected implementation of Date.
359		(Still need to check for correctness; implement better canonicalizeDate.)
360		11. Added "scan" to signature IEEE_REAL.
361		12. Some improvements to IntInf [in particular: efficiency-hack for
362		mod and rem when second operand is 2 (for parity checks).]
363		13. Changed representation of type Time.time, using a single IntInf.int
364		value counting microseconds.  This considerably simplified the
365		implementation of structure Time.  We now support negative time
366		values; scan and fromString handle signs.
367		14. Functor PrimIO now takes two additional arguments (VectorSlice and
368		ArraySlice).

371		Name: Matthias Blume (blume (at) tti - c (dot) org)
372		Date: 2003/08/28 17:00:00 CDT
373		Tag: blume-20030828-intinf
374		Description:
375
376		This is a major update which comes with a version number bump
377		(110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
378		and an implementation of IntInf in the Basis.
379
380		There are a fairly large number of related changes and updates throughout
381		the system:
382
383		Basis:
384		- Implemented IntInf.
385		- Made LargeInt a projection of IntInf (by filtering through INTEGER).
386		- Added some missing Real64 operations, most notably Real.toLargeInt.
387		- Added FixedInt as a synonym for Int32.
388
389		compiler:
390		* Added support for a built-in intinf type.
391		- literals
392		- pattern matching
393		- conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
394		- overloading on literals and operations
395
396		This required adding a primitive type intinf, some additional
397		primops, and implementations for several non-trivial intinf
398		operations in Core.  (The intinf type is completely abstract
399		to the compiler; all operations get delegated back to the Core.)
400
401		* Intinf equality is handled by polyequal.  However, the compiler
402		does not print its usual warning in this case (since polyequal
403		is the right thing to do there).
404
405		* Improved the organization of structure InlineT.
406
407		* A word about conversion primops:
408		If conversions involving intinf do not cancel out during
409		CPS contract, then the compiler must insert calls to Core functions.
410		Since all core access must be resolved already during the FLINT
411		translate phase, it would be too late a the time of CPS contract
412		to add new Core calls.  For this reason, conversion primops
413		for intinf carry two arguments:  1. the numeric argument that
414		they are supposed to convert, and 2. the Core function that
415		can help with this conversion if necessary.  If CPS contract
416		eliminates a primop, then the associated Core function becomes
417		dead and goes away.  Intinf conversion primops that do not get
418		eliminated by CPS contract get rewritten into calls of their
419		core functions by a separate, new phase.
420
421		interactive system:
422		- Control.Print.intinfDepth controls max length of intinf constants
423		being printed. (Analogous to Control.Print.stringDepth.)
424		- Cleanup in printutil and pputil: got rid of unused stuff and
425		duplicates; replaced some of the code with code that makes better
426		use of library functionality.
427
428		CM:
429		Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
430		are no longer silent.
431
432		CKIT:
433		Fixed mismatched uses of Int32 and LargeInt.  I always decided
434		in favor of LargeInt -- which is now the same as IntInf.
435		CKIT-knowledgable people should check whether this is what's
436		intended and otherwise change things back to using Int32 or
437		FixedInt.
438
439		Throughout the code:
440		Started using IntInf.int literals and built-in operations
441		(e.g., comparison with 0) where this seems appropriate.

449
450		Merging changes from the mcz-branch development branch into trunk.
451		These changes involve replacement of the emulated old prettyprinter
452		interface with direct use of the SML/NJ Lib PP library, and fixing
453		of a couple of bugs (895, 1186) relating to error messages.  A new
454		prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
455		has been added.

461		Description:
462
463		Version number bumped to 110.42.9.  NEW BOOTFILES!!!
464
465		http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
466
467		This patch restores SML/NJ's ability to run under win32.  There are a
468		number of changes, including fixes for several bugs that had gone
469		unnoticed until now:
470
471		- uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
472		trying to run the win32 version from within cygwin.)
473
474		- There are a number of simple .bat scripts that substitute for their
475		corresponding Unix shell-scripts.  (See below.)
476
477		- The internals of ml-build have been modified slightly.  The main
478		difference is that instead of calling ".link-sml" (or link-sml.bat)
479		using OS.Process.system, the ML process delegates this task back
480		to the script.  Otherwise problems arise in mixed environments such
481		as Cygwin where scripts look and work like Unix scripts, but
482		where OS.Process.system cannot run them.
483
484		- In CM, the srcpath pickler used native pathname syntax -- which
485		is incorrect in the case of cross-compilation.  The new pickle format
486		is independent of platform-specific naming conventions.
487
488		- Path configuration files (such as lib/pathconfig) can now choose
489		between native and standard syntax.  Placing a line of the form
490
491		standard!
492
493		into the file causes all subsequent paths to be interpreted using
494		CM standard pathname syntax (= Unix conventions); a line
495
496		native!
497
498		switches back to native style.  This was needed so that
499		path config files can be written portably, see src/system/pathconfig.
500
501		- Runtime system:
502
503		- win32-filesys.c:  get_file_time and set_file_time now
504		access modification time, not creation time.
505
506		- I/O code made aware of new array representation.
507
508		- Bug fixes in X86.prim.masm.
509
510		- src/system/makeml made aware of win32. (For use under cygwin
511		and other Unix-environments for windows.)
512
513		- In Basis, fixed off-by-one error in win32-io.sml (function vecF)
514		which caused BinIO.inputAll to fail consistently.
515
516		.bat scripts:
517
518		Windows .bat scripts assume that SMLNJ_HOME is defined.
519
520		- sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
521		applications (sml, ml-yacc, ml-lex).
522		- ml-build.bat: analogous to ml-build.
523		- config\install.bat:  Analogous to config/install.sh.  This requires
524		that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
525		(nmake etc. must be on the path, and vcvars32 must have been run.)
526		Moreover, sources for ml-lex and ml-yacc need to exist under src,
527		and the bootfile hierarchy must have been unpacked under
528		sml.boot.x86-win32.
529		The script is very primitive and does a poor job at error checking.
530		It only installs the base system, ml-lex, and ml-yacc.  No other
531		libraries are being installed (i.e., you get only those that
532		are part of the compiler.)
533		- link-sml.bat:  analogous to .link-sml, but not currently used
534
535		Unrelated bug fixes:
536
537		- ml-nlffigen now exports structures ST_* corresponding to incomplete
538		types.
539		- Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
540		otherwise.)

577		Description:
578
579		1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
580
581		This mainly affects the quality of error messages.  However, some
582		of the code is now more straightforward than before. (Treatment of
583		the above four constructs in translate.sml is much simpler than
584		the "macro-expansion" that was going on before.  Plus, the mach-
585		compiler no longer gets invoked just to be able to compile an
586		if-expression.)
587
588		2. The ErrorMsg.Error exception is now caught and absorbed by the
589		interactive loop.

595		Description:
596
597		Ported the runtime system to cygwin, which uses the unix
598		x86-unix bin files.  Missing/buggy features:
599
600		o getnetbyname, getnetbyaddr: these functions seem to be missing in
601		the Cygwin library.
602		o Ctrl-C handling may be flaky.
603		o Windows system calls and Windows I/O are not supported.
604
605		A new set of binfiles is located at:
606
607		http://www.dorsai.org/~leunga/boot.x86-unix.tgz
608
609		This is only needed for bootstrapping the cygwin version of smlnj.

639		spilled.  (Because of this bug, e.g., nucleic stopped compiling between
640		110.37 and 110.38.)

889		Description:
890
891		All pseudo-ops emitted before the first segment declaration
892		such as TEXT, DATA, and BSS directives are assumed to be global
893		declarations and are emitted first in the assembly file. This is
894		useful in a number of situations where one has pseudo-ops that are not
895		specific to any segment, and also works around the constraint that one
896		cannot have client pseudo-ops in the TEXT segment.
897
898		Because no segment is associated with these declarations it is
899		an error to allocate any space or objects before the first segment
900		directive and an exception will be raised. However, we cannot make
901		this check for client pseudo-ops.
902
903		These top level declarations are a field in the CFG graph_info.
904		In theory you can continue to add to this field after the CFG has been
905		built -- provided you know what you are doing;-)

929
930		Applied the following bugfix provided by Emden Gansner:
931
932		Output is corrupted when outputSubstr is used rather than output.
933
934		The problem occurs when a substring
935
936		ss = (s, dataStart, dataLen)
937
938		where dataStart > 0, fills a stream buffer with avail bytes left.
939		avail bytes of s, starting at index dataStart, are copied into the
940		buffer, the buffer is flushed, and then the remaining dataLen-avail
941		bytes of ss are copied into the beginning of the buffer. Instead of
942		starting this copy at index dataStart+avail in s, the current code
943		starts the copy at index avail.
944
945		Fix:
946		In text-io-fn.sml, change line 695 from
947		val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
948		to
949		val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)
