+ Description:
+ Some rationalization of names:
+    structure BTrace -> structure TDPInstrument
+    etc.
+ This is is preparation of using the original back-trace
+ instrumentation for other purposes.  "TDP" stands for
+ Trace/Debug/Profile.
+ The control flag controlling whether instrumentation is on or off is now
+ registered under a different name, so instead of running sml as
+  sml -Cinstrument.btrace-mode=true
+ one has to say
+  sml -Ctdp.instrument=true

+ Description:
+ Made some minor modifications to elabcore.sml to have source regions
+ be propagated more tightly -- resulting in better (i.e., smaller)
+ regions being reported in error- and debug messages.

+ Tag: blume-20041008-cmkw
+ Description:
+ Fixed handling of keywords in .cm files: After seeing "is" the lexer
+ treats subsequent occurrences of "group", "library", "source", "is",
+ "*", and "-" as ordinary identifiers rather than keywords.
+ Most seriously, this fixes a problem with CM's "shell" tool.  The tool
+ is supposed to accept a tool argument called "source", but this did
+ not work because of the clash with the keyword.

+ Description:
+ Assorted cleanup work:
+   - got rid of intstrmap in favor of using the library's
+     hash table implementation
+   - threw out most of the pathnames stuff, as it was not used anyway
+   - simplified tokentable implementation
+   - fixed some minor spelling errors

+ Description:
+ Cleaned up the absyn to reflect the invariant that HANDLE always
+ carries a FNexp as part of the type definition.  This eliminates some
+ superfluous sanity checks at runtime down the road.
+ Some minor cleanup of the btrace code.

+ Tag: blume-20041001-slave
+ Description:
+ Added hack to make slave mode work in the presence of the version
+ tool.  (Still, since the master does two passes over the code for
+ CMB.make, the release number gets bumped twice when slaves are
+ attached.  I don't know if this is worth fixing...)

+ Tag: blume-20040930-version
+ Description:
+ * Moved the "version" magic into its own little library under
+ src/system/smlnj/internal.  This avoids expensive reconstruction
+ of a stable src/compiler/core.cm.
+ * At the same time, structure CompilerVersion is now known as structure
+ SMLNJVersion.
+ * Arranged for the version tool to NOT kick in when rebuilding the system
+   (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
+   Also, loading the versiontool does not work when rebuilding the system
+   because CM is not properly initialized at that time.

+ Tag: blume-20040929-autoversion
+ Description:
+ Implemented some CM magic to have
+     file src/compiler/TopLevel/main/version.sml
+ generated automagically.
+ The version is taken from two files: config/version and config/release.
+ The first is expected to contain a two-part version number such as 110.49.
+ The second should contain a single number, but it may be missing.
+ If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
+ time the version tool is loaded (which is the first time you say CMB.make),
+ then the tool will increment the value stored in config/release every
+ time CMB.make is invoked.
+ The binfile format is now insensitive to anything beyond the first
+ two components of a version number, so bumping the release does not render
+ binfiles incompatible.  Auto-bumping can be used to keep track of versions
+ during development without invalidating existing binfiles.
+ In any case, every CMB.make updates the date information in version.sml.
+ (This is the date that is printed in the banner.)

+ Description:
+ Some cleanup of the controls code.
+ ----------------------------------------------------------------------
+ Name: Matthias Blume (blume (at) tti - c (dot) org)
+ Date: 2004/09/27 22:08:00 CDT
+ Tag: blume-20040927-controls
+ Description:
+ Added two pieces of functionality to the Controls interface:
+.   val save'restore: 'a control -> unit -> unit
+    grabs the current value of the control in stage 1 and restores it
+    in stage 2.
+.   val set' : 'a control * 'a -> unit -> unit
+    stores the given value into the control in stage 2 (i.e., delayed)
+    but does all error checking in stage 1.
+    (This is for string controls that need to do parse their argument --
+     something that might fail.  In some cases, notably in CM, one
+     already knows the intended argument but wants to delay the actual
+     assignment until a time when error recovery would be more difficult.)
+ Changed the handling of controls in tool arguments to classes "sml" and
+ "lazysml":
+    - use Controls.save'restore as a more robust way of restoring the
+      old value (in particular: without having to re-parse the string)
+    - use controls to handle the "overload" keyword in the init group
+      (I believe this change actually fixes a long-standing obscure bug.)

+ Date: 2004/09/27 17:00:00 CDT
+ Tag: blume-20040927-lazysml
+ Description:
+ Added a new tool class called "lazysml" to CM's tool chest.  The only
+ difference to "sml" is that compilation is done with Control.lazysml
+ set to true.  A source of class "lazysml" is automatically recognized
+ by a file name suffix of ".lml".
+ In addition to the above feature, the original class "sml" now also
+ supports a tool argument "lazy" which has the same effect.  As a
+ result, the following three lines are equivalent:
+     foo.sml : lazysml
+     foo.sml : sml (lazy)
+     foo.sml (lazy)
+ The setting goes into effect both during parsing and during
+ compilation.  The original setting is restored right after parsing and
+ after compilation, respectively.
+ In addition to all the above, there is also a general mechanism to set
+ ANY of the "controls" that are available at the command line via
+ "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
+ apply as well. (In fact, "lazy" is implemented as a special case of
+ the general mechanism.)
+ The .cm file syntax uses a new keyword tool argument called "with".
+ There are several ways of indicating the desired settings:
+     foo.sml (with:parser.quotations=true)
+     foo.sml (with:(name:parser.quotations value:true))
+     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
+     foo.sml (with:(name1=value1 name2=value2 ...))
+     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
+     etc.
+ Another possible abbreviation is to leave out the =v or value:v part
+ if the name refers to a boolean control (in which case the value is
+ taken to be true).  Thus, one could get lazy sml also by saying:
+     foo.sml (with:parser.lazy-keyword=true)
+     foo.sml (with:parser.lazy-keyword)
+     foo.sml (with:(name:parser.lazy-keyword value:true))
+     foo.sml (with:(name:parser.lazy-keyword))

+ Description:
+ Changed the interface of structures Timer and Unix to match the most
+ recent Basis spec.
+ In the case of Unix there still seems to be an open/weird issue:
+    The {text,bin}{In,Out}streamOf functions are supposed to create
+    fresh streams whenever they are called -- as opposed to have them
+    return the same stream every time.  This design is supposed to
+    prevent space leaks caused by proc values hanging on to streams.
+    The reap function, on the other hand, is supposed to close the
+    streams.  This cannot be done without having a handle on the
+    stream in proc after all...
+ I took the liberty to implement the following stopgap solution:
+   The proc value hangs on to the most recently created stream(s).
+   Reap closes those.  If either or both of the two streams hadn't
+   been created at all yet, then reap will close the corresponding
+   file descriptors directly.
+ PS: I don't understand the original space leak argument anymore.  If
+ a proc hangs on to the imperative stream, then I/O operations on those
+ will advance the state of the cached stream and avoid the space leak.

+ is to have CM check that for each group there is precisely one owning
+ library.
+ The advantage of the new scheme is that the programmer no longer needs
+ to maintain the somewhat annoying owner information.  The downside is
+ that CM cannot enforce the ownership rule across multiple runs of
+ CM.make.  Fortunately, enclosing the same group in two different
+ libraries A and B which are not part of the same program does not
+ cause real problems.

+ Description:
+ Arranged for ml-build to clean up after itself a little bit better.
+ The script generates a temporary SML source file and compiles it using
+ CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
+ gets rid of those at the end, so they don't accumulate under .cm.
+ This required a minor change to install.sh because the name of the
+ metadata directory (default: .cm) is actually configurable at
+ installation time.

+ Tag: blume-20040511-win32sock
+ Description:
+ Added previously missing support for many socket-related functions
+ under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
+ for the voluminous patch!
+ (I have not tested this patch under win32 yet.)
+ Here is David's e-mail:
+ Hi,
+ Attached to this email you find a diff against sml/nj 110.45
+ that will enable socket support under Windows.
+ To apply the patch (using unix or cygwin)
+) gunzip runtime.diff.gz
+) "cd" into "src/runtime" in the source tree of a fresh
+.45 installation.
+) patch -p 1 < [your/path/to]runtime.diff
+ The code compiles fine but has NOT yet been extensively tested.
+ I only ran a few tests for basic socket client functionality
+ (which worked fine).  Especially the functions that use ioctl
+ are not tested at all and might not work (see below).
+ I implemented this since we want to move to a newer version of sml/nj
+ but need socket support in order to use it.  This is the first time I
+ even had a look at the sml/nj source,  so please review my changes
+ before making this part of the distribution!  Here are a few issues
+ that I think might be better for someone to solve who is more
+ familiar with the sml/nj source (and socket programming):
+ - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
+   exception since I could not figure out what the windows equivalent
+   of these functions is
+ - In sockets-osdep.h there are a some #include statements that are
+   only used in a few files that include sockets-osdep.h
+ - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
+   does not process its return value since I don't know how to
+   report an error upwards.
+ - It would probably be good to have a call to WSACleanup() when
+   the library is unloaded (if there is such a possibility).
+   Otherwise I think Windows will take care of this automatically
+   when the process finishes.
+ - I used ioctlsocket() as a replacement for ioctl() but I have
+   no idea if that is actually the proper replacement on Windows.
+ - All these issues are marked in the code by "FIXME" comments.
+ We use sml/nj extensively in our products and are quite happy
+ with it.  I hope this contribution will help you.
+ Keep up the good work!
+ David

+ Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
+ of SML/NJ.  The problem is that
+    lib = dlopen(NULL, ...)
+    f   = dlsym(lib, "malloc");
+ does not work on Windows unless we explicitly export symbols
+ such as 'malloc' during linking.  We fixed this by explicitly
+ exporting the required symbols with the magic gcc incantation:
+     -Wl,--export-all cygwin.def
+ where cygwin.def is a file containing all the symbols that
+ we wish to export.
+ I suspect this is a Windows problem and we'll have to
+ do the same (somehow with windows compilers) when
+ we build the native win32 version with the system
+ calls LoadLibrary/GetProcAddress.

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

+ Another installer tweak:  All the ML code for the installer is now
+ compiled during CMB.make and put into a little library called
+ $smlnj/installer.cm.  The installation then simply invokes
+    sml -m $smlnj/installer.cm
+ and everything happens automagically.
+ Win32:  ML code senses value of environment variable SMLNJ_HOME.
+ Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
+         and BINDIR.
+ The new scheme guarantees that the ML code responsible for the installation
+ is in sync with the APIs of the main system.  Also, the installer is
+ somewhat faster because the installer script is precompiled.

+ Description:
+. Fixed SOCKET API and implementation to match Basis spec.
+    This required changing the internal representation of sockets to one
+    that remembers (for each socket file descriptor) whether it is currently
+    blocking or non-blocking.  This state is maintained lazily (i.e., a system
+    call is made only if the state actually needs to change).
+. OS-specific details of sockets were moved into separate files, thus
+    making it possible to unify the bulk of the socket implementations
+    between Unix and Win32.
+. CML's socket API changed accordingly.
+    (Note that we need to remove non-blocking functions from this API
+    since they are redundant in the case of CML!)
+. CML's socket implementation now makes use of non-blocking functions
+    provided by Basis, thus removing all OS-dependent code from this part
+    of CML.
+. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

+ The installer can now install everything under Win32
+ as well as under *nix as long as it compiles.
+ Other changes:
+   - made CML compile again under Win32
+   - made eXene compile under Win32 (by providing a fake structure UnixSock
+     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
+   - fixed a bug in nowhere: it assumed that type OS.Process.status is the
+     same as type int;  under Win32 it isn't
+   - fixed some slice-related problems in the win32-specific parts of CML
+   - added a functor argument "sameVol" to os-path-fn.sml in the Basis
+     (under Win32, the volume name is case-insensitive, and the
+     OS.Path code compares volume names for equality)

+ Description:
+. Changed interface to vectors and arrays in Basis to match
+      (draft) Basis spec.
+. Added signatures and implementations of slices according to
+      Basis spec.
+. Edited source code throughout the system to make it compile again
+      under 1. and 2.  (In some cases code had to be added to have it
+      match the new signatures.)
+. MLRISC should be backward-compatible: the copies of the originals
+      of files that needed to change under 3. were retained, the .cm files
+      check the compiler version number and use old versions when
+      appropriate.
+. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
+      dirstream -> string option (in accordance with Basis spec).
+. When generating code that counts lines, ml-lex used function
+      CharVector.foldli, taking advantage of its old interface.
+      This has been replaced with the corresponding code from
+      CharVectorSlice.  (html-lex must be re-lexed!)
+. BitArray in smlnj-lib/Util has been extended/modified to match the
+      new MONO_ARRAY signature.  (Do we need BitArraySlice?)
+. Removed temporary additions (fromInternal, toInternal) from the
+      (now obsolete) IntInf in smlnj-lib/Util.
+. Cleaned up structure Byte.
+. Added localOffset, scan, and fromString to Date (according to spec).
+      Cleaned/corrected implementation of Date.
+      (Still need to check for correctness; implement better canonicalizeDate.)
+. Added "scan" to signature IEEE_REAL.
+. Some improvements to IntInf [in particular: efficiency-hack for
+      mod and rem when second operand is 2 (for parity checks).]
+. Changed representation of type Time.time, using a single IntInf.int
+      value counting microseconds.  This considerably simplified the
+      implementation of structure Time.  We now support negative time
+      values; scan and fromString handle signs.
+. Functor PrimIO now takes two additional arguments (VectorSlice and
+      ArraySlice).

+         - Added some missing Real64 operations, most notably Real.toLargeInt.
+         - Added FixedInt as a synonym for Int32.
+ compiler:
+         * Added support for a built-in intinf type.
+           - literals
+           - pattern matching
+           - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
+           - overloading on literals and operations
+         This required adding a primitive type intinf, some additional
+         primops, and implementations for several non-trivial intinf
+         operations in Core.  (The intinf type is completely abstract
+         to the compiler; all operations get delegated back to the Core.)
+         * Intinf equality is handled by polyequal.  However, the compiler
+         does not print its usual warning in this case (since polyequal
+         is the right thing to do there).
+         * Improved the organization of structure InlineT.
+         * A word about conversion primops:
+         If conversions involving intinf do not cancel out during
+         CPS contract, then the compiler must insert calls to Core functions.
+         Since all core access must be resolved already during the FLINT
+         translate phase, it would be too late a the time of CPS contract
+         to add new Core calls.  For this reason, conversion primops
+         for intinf carry two arguments:  1. the numeric argument that
+         they are supposed to convert, and 2. the Core function that
+         can help with this conversion if necessary.  If CPS contract
+         eliminates a primop, then the associated Core function becomes
+         dead and goes away.  Intinf conversion primops that do not get
+         eliminated by CPS contract get rewritten into calls of their
+         core functions by a separate, new phase.
+ interactive system:
+         - Control.Print.intinfDepth controls max length of intinf constants
+         being printed. (Analogous to Control.Print.stringDepth.)
+         - Cleanup in printutil and pputil: got rid of unused stuff and
+         duplicates; replaced some of the code with code that makes better
+         use of library functionality.
+ CM:
+         Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
+         are no longer silent.
+ CKIT:
+         Fixed mismatched uses of Int32 and LargeInt.  I always decided
+         in favor of LargeInt -- which is now the same as IntInf.
+         CKIT-knowledgable people should check whether this is what's
+         intended and otherwise change things back to using Int32 or
+         FixedInt.
+ Throughout the code:
+         Started using IntInf.int literals and built-in operations
+         (e.g., comparison with 0) where this seems appropriate.

+ Description:
+ Version number bumped to 110.42.9.  NEW BOOTFILES!!!
+     http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
+ This patch restores SML/NJ's ability to run under win32.  There are a
+ number of changes, including fixes for several bugs that had gone
+ unnoticed until now:
+   - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
+     trying to run the win32 version from within cygwin.)
+   - There are a number of simple .bat scripts that substitute for their
+     corresponding Unix shell-scripts.  (See below.)
+   - The internals of ml-build have been modified slightly.  The main
+     difference is that instead of calling ".link-sml" (or link-sml.bat)
+     using OS.Process.system, the ML process delegates this task back
+     to the script.  Otherwise problems arise in mixed environments such
+     as Cygwin where scripts look and work like Unix scripts, but
+     where OS.Process.system cannot run them.
+   - In CM, the srcpath pickler used native pathname syntax -- which
+     is incorrect in the case of cross-compilation.  The new pickle format
+     is independent of platform-specific naming conventions.
+   - Path configuration files (such as lib/pathconfig) can now choose
+     between native and standard syntax.  Placing a line of the form
+         standard!
+     into the file causes all subsequent paths to be interpreted using
+     CM standard pathname syntax (= Unix conventions); a line
+         native!
+     switches back to native style.  This was needed so that
+     path config files can be written portably, see src/system/pathconfig.
+   - Runtime system:
+       - win32-filesys.c:  get_file_time and set_file_time now
+         access modification time, not creation time.
+       - I/O code made aware of new array representation.
+       - Bug fixes in X86.prim.masm.
+    - src/system/makeml made aware of win32. (For use under cygwin
+         and other Unix-environments for windows.)
+    - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
+      which caused BinIO.inputAll to fail consistently.
+ .bat scripts:
+    Windows .bat scripts assume that SMLNJ_HOME is defined.
+    - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
+      applications (sml, ml-yacc, ml-lex).
+    - ml-build.bat: analogous to ml-build.
+    - config\install.bat:  Analogous to config/install.sh.  This requires
+      that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
+      (nmake etc. must be on the path, and vcvars32 must have been run.)
+      Moreover, sources for ml-lex and ml-yacc need to exist under src,
+      and the bootfile hierarchy must have been unpacked under
+      sml.boot.x86-win32.
+      The script is very primitive and does a poor job at error checking.
+      It only installs the base system, ml-lex, and ml-yacc.  No other
+      libraries are being installed (i.e., you get only those that
+      are part of the compiler.)
+    - link-sml.bat:  analogous to .link-sml, but not currently used
+ Unrelated bug fixes:
+   - ml-nlffigen now exports structures ST_* corresponding to incomplete
+     types.
+   - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
+     otherwise.)
