+ Tag: blume-20040913-config-mlrisc
+ Description:
+ Put target "mlrisc" back into the default list.
+ (There is no harm in having it, and some users have expressed their
+ wish to have "mlrisc" included by default.)

+ Tag: leunga-20040903-cygwin-install
+ Description:
+    Added a patch to _arch-n-opsys to enable the Cygwin runtime.
+ The Cygwin runtime is turned on by setting the environment
+ variable SMLNJ_CYGWIN_RUNTIME to 1.

+ Tag: blume-20040830-installer
+ Description:
+ Upon request by Johannes Joemann:
+ - improved ML code of installer to fall back to coping when renaming
+   fails (i.e., when source and target are on different file systems);
+   the code compiles but has yet to be tested in anger
+ - removed mlrisc from list of default targets (config/targets)

+ Tag: leunga-110_47-dijsktra
+ Description:
+ Bug fix from Carl Hauser:
+ single_source_shortest_paths in dijkstra.sml was observed to get wrong
+ answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
+ The problem is that following the expression A.update(dist,s,Num.zero)
+ it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

+ Tag: blume-20040806-cmdline
+ Description:
+ Fiddled with handling of command-line options:
+   * sml now quits after processing the command line
+     if -H, -S, -h<n>, or -s<n> appears as the last
+     command-line argument
+   * a new option -q terminates the session when encountered on
+     the command line; subsequent arguments will be ignored
+   * bug fixes: short (erroneous) arguments are no longer ignored
+     completely

+ Description:
+   - Added minimal IBM assembly syntax support for PowerPC.
+   - Cygwin: manually changed the file cygwin.def.  Some exported symbols have
+     been altered in the runtime.  We need an automatic way to keep the file
+     in sync.

+ Backed out of change to win32-filesys.c.  The earlier patch to

+ Description:
+ Added NLFFI support for Win32, adapted from a patch provided by David
+ Hansel.  This is currently completely untested.  Also, the issue
+ concerning stdcall vs. ccall is still unresolved.

+ Tag: blume-20040730-various
+ Description:
+ Gearing up towards 110.47...
+ - various minor bugfixes to ml-nlffigen
+ - a beginning of a manual for nlffi
+ - eliminated 'export name=value' in config/install.sh as this does
+   not work with certain versions of /bin/sh
+   (Thanks to David King at Motorola for catching this.)
+ - several bugfixes provided or suggested by David Hansel at Reactive Systems:
+   - added a test for tm==NULL to gmtime.c and localtime.c
+   - applied patch for incorrect GetFileTime under win32
+   - toSeconds -> toMilliseconds in Win32/win32-process.sml

+ Tag: blume-20040721-nlffigen
+ Description:
+ - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
+   for a typedef to an incomplete type, but leave out the "typ" member.
+   (This is just for consistency.)
+ - Started to produce what is supposed to become better (i.e., comprehensive)
+   documentation of what ml-nlffigen does and produces.

+ Tag: blume-20040714-union
+ Description:
+ Added C_UNION to c-calls/c-types.sml and updated the machinery
+ (ml-nlffigen, cproto.sml) that conveys C function interface
+ information to the code generator.
+ However, the actual architecture-specific implementation of function
+ arguments and results that are C unions is still not implemented.

+ Tag: leunga-110_46_1-ppc-lwzu
+ Description:
+     Added these instructions to the PowerPC architecture:
+     LBZU(X), LHZU(X), LWZU(X),
+     STWU(X), STFDU, STFSU
+     etc...
+     Note: I haven't added their instruction encoding into the description.

+ Description:
+    Added the two instructions LWARX and STWCX to the PowerPC
+ instruction set.
+    A (untested) rewrite of loop-structure.sml.  The old version
+ is completely broken.

+ Tag: blume-20040713-nlffi
+ Description:
+ - use paramAlloc to report c-calls with too many arguments
+   (for PPC version where parameter area is pre-allocated)
+ - added ccall_maxargspace to machspec (to implement the above)
+ - made "make" commend in CM's "make" tool configurable
+ - added option (default: on) for passing the name of the SML/NJ's "bin"
+   directory to "make"; the call looks like this:
+      make <options> SMLNJ_BINDIR=<dir> <target>
+   This can be used by the Makefile to, e.g., pick the "right" version
+   of ml-nlffigen.
+ - minor code tweaks

+ Tag: blume-110_46_1-macosx-nlffi
+ Description:
+ NLFFI under Mac OS X now working (sort of).  This is largely untested,
+ though.
+ Note:  1. You have to make a new, clean build of the runtime system.
+. There are new BOOTFILES, you have to use them!
+           (Doing the bootstrap process yourself would be *very* painful!
+            If you absolutely have to do it, build the system under
+            a different architecture and then cross-compile.)
+ Version bumped to 110.46.1 to account for runtime data format changes.

+ Tag: blume-20040618-unix
+ Description:
+ Changed the implementation of structure Unix so that the same stream
+ is returned every time one of the {text,bin}{In,Out}streamOf functions
+ is invoked on the same proc.  This is not what the spec currently
+ says -- although IMO it arguably should.  (See discussion below.)

+ Tag: blume-20040617-timer-unix
+ 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.
