17		Date: 2004/08/09 12:21:00 EST
18		Tag: leunga-110_47-dijsktra
19		Description:
20
21		Bug fix from Carl Hauser:
22
23		single_source_shortest_paths in dijkstra.sml was observed to get wrong
24		answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
25
26		The problem is that following the expression A.update(dist,s,Num.zero)
27		it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

32		Tag: blume-20040806-cmdline
33		Description:
34
35		Fiddled with handling of command-line options:
36
37		* sml now quits after processing the command line
38		if -H, -S, -h<n>, or -s<n> appears as the last
39		command-line argument
40		* a new option -q terminates the session when encountered on
41		the command line; subsequent arguments will be ignored
42		* bug fixes: short (erroneous) arguments are no longer ignored
43		completely

47		Date: 2004/08/04 18:17:00 EST
48		Tag: leunga-110_47-ppc-ibm-asm
49		Description:
50
51		- Added minimal IBM assembly syntax support for PowerPC.
52
53		- Cygwin: manually changed the file cygwin.def.  Some exported symbols have
54		been altered in the runtime.  We need an automatic way to keep the file
55		in sync.

59		Date: 2004/08/04 14:00:00 CDT
60		Tag: Release_110_47
61		Description:
62
63		New working version (110.47).  NEW BOOTFILES!

66		Name: Matthias Blume (blume (at) tti - c (dot) org)
67		Date: 2004/08/03 14:25:00 CDT
68		Tag: blume-20040803-callingconv
69		Description:
70
71		Added low-level support for choosing C calling conventions by
72		twiddling the type of rawccall.  (See
73		src/compiler/Semant/types/cproto.sml for details.)

75		----------------------------------------------------------------------
76		Name: Matthias Blume (blume (at) tti - c (dot) org)
77		Date: 2004/08/02 15:55:00 CDT
78		Tag: blume-20040802-backout
79		Description:
80
81		Backed out of change to win32-filesys.c.  The earlier patch to
82		get_file_time caused CM to produce files with the wrong time stamp.
83
84		----------------------------------------------------------------------
85		Name: Matthias Blume (blume (at) tti - c (dot) org)
86		Date: 2004/08/02 14:45:00 CDT
87		Tag: blume-20040802-nlffi-win32
88		Description:
89
90		Added NLFFI support for Win32, adapted from a patch provided by David
91		Hansel.  This is currently completely untested.  Also, the issue
92		concerning stdcall vs. ccall is still unresolved.
93

96		Date: 2004/07/30 17:55:00 CDT
97		Tag: blume-20040730-various
98		Description:
99
100		Gearing up towards 110.47...
101
102		- various minor bugfixes to ml-nlffigen
103		- a beginning of a manual for nlffi
104
105		- eliminated 'export name=value' in config/install.sh as this does
106		not work with certain versions of /bin/sh
107		(Thanks to David King at Motorola for catching this.)
108
109		- several bugfixes provided or suggested by David Hansel at Reactive Systems:
110		- added a test for tm==NULL to gmtime.c and localtime.c
111		- applied patch for incorrect GetFileTime under win32
112		- toSeconds -> toMilliseconds in Win32/win32-process.sml
113
114		----------------------------------------------------------------------
115		Name: Matthias Blume (blume (at) tti - c (dot) org)
116		Date: 2004/07/21 18:20:00 CDT
117		Tag: blume-20040721-nlffigen
118		Description:
119
120		- Fixed minor issue in ml-nlffigen: Now generate structure T_foo
121		for a typedef to an incomplete type, but leave out the "typ" member.
122		(This is just for consistency.)
123		- Started to produce what is supposed to become better (i.e., comprehensive)
124		documentation of what ml-nlffigen does and produces.
125
126		----------------------------------------------------------------------
127		Name: Matthias Blume (blume (at) tti - c (dot) org)
128		Date: 2004/07/14 16:25:00 CDT
129		Tag: blume-20040714-union
130		Description:
131
132		Added C_UNION to c-calls/c-types.sml and updated the machinery
133		(ml-nlffigen, cproto.sml) that conveys C function interface
134		information to the code generator.
135
136		However, the actual architecture-specific implementation of function
137		arguments and results that are C unions is still not implemented.
138
139		----------------------------------------------------------------------
140		Name: Allen Leung (leunga (at) reservoir (dot) com)
141		Date: 2004/07/14 14:38:00 EST
142		Tag: leunga-110_46_1-ppc-lwzu
143		Description:
144
145		Added these instructions to the PowerPC architecture:
146		LBZU(X), LHZU(X), LWZU(X),
147		STWU(X), STFDU, STFSU
148
149		etc...
150
151		Note: I haven't added their instruction encoding into the description.
152
153		----------------------------------------------------------------------
154		Name: Allen Leung (leunga (at) reservoir (dot) com)
155		Date: 2004/07/13 15:04:00 EST
156		Tag: leunga-110_46_1-ppc-lwarx
157		Description:
158
159		Added the two instructions LWARX and STWCX to the PowerPC
160		instruction set.
161
162		A (untested) rewrite of loop-structure.sml.  The old version
163		is completely broken.
164
165		----------------------------------------------------------------------
166		Name: Matthias Blume (blume (at) tti - c (dot) org)
167		Date: 2004/07/13 13:50:00 CDT
168		Tag: blume-20040713-nlffi
169		Description:
170
171		- use paramAlloc to report c-calls with too many arguments
172		(for PPC version where parameter area is pre-allocated)
173		- added ccall_maxargspace to machspec (to implement the above)
174		- made "make" commend in CM's "make" tool configurable
175		- added option (default: on) for passing the name of the SML/NJ's "bin"
176		directory to "make"; the call looks like this:
177
178		make <options> SMLNJ_BINDIR=<dir> <target>
179
180		This can be used by the Makefile to, e.g., pick the "right" version
181		of ml-nlffigen.
182		- minor code tweaks
183
184		----------------------------------------------------------------------
185		Name: Matthias Blume (blume (at) tti - c (dot) org)
186		Date: 2004/07/12 22:50:00 CDT
187		Tag: blume-110_46_1-macosx-nlffi
188		Description:
189
190		NLFFI under Mac OS X now working (sort of).  This is largely untested,
191		though.
192
193		Note:  1. You have to make a new, clean build of the runtime system.
194		2. There are new BOOTFILES, you have to use them!
195		(Doing the bootstrap process yourself would be *very* painful!
196		If you absolutely have to do it, build the system under
197		a different architecture and then cross-compile.)
198
199		Version bumped to 110.46.1 to account for runtime data format changes.
