19		Description:
20
21		Compilers that generate assembly code may produce  global labels
22		whose value is resolved at link time. The various peephole optimization
23		modules did not take this in account.
24
25		TODO. The Labels.addrOf function should really return an option
26		type so that clients are forced to deal with this issue, rather
27		than an exception being raised.

33		Description:
34
35		1. A bug fix from Allen.
36
37		A typo causes extra fstp %st(0)'s to be generated at compensation
38		edges, which might cause stack underflow traps at runtime.  This
39		occurs in fft where there are extraneous fstps right before the 'into'
40		trap instruction (in this case they are harmless since none of the
41		integers overflow.)
42
43		2. Pulled out various utility modules that were embedded in the modules
44		of the register allocator. I need these modules for other purposes, but
45		they are not complete enough to put into a library (just yet).

49		Tag: blume-20020131-sparc-ccalls
50		Description:
51
52		1. C-calls on Sparc needlessly allocated a huge chunk (96 bytes)
53		of extra stack space by mistake.  Fixed.
54
55		2. Bug in logic of handling of command-line options in ml-nlffigen fixed.

60		Tag: leunga-20020130-nowhere-bug-fix
61		Description:
62
63		MLRISC bug fixes:
64		1. Fixed a bindings computation bug in the 'nowhere' program generator tool.
65		2. MachineInt.fromString was negating its value.

70		Tag: blume-20020129-INSTALL
71		Description:
72
73		- Added somewhat detailed installation instructions (file INSTALL).
74		- Fixed curl-detection bug in config/install.sh.
75		- It is now possible to select the URL getter using the URLGETTER
76		environment variable:
77
78		not set / "unknown"      --> automatic detection (script tries wget,
79		curl, and lynx)
80		"wget" / "curl" / "lynx" --> use the specified program (script "knows"
81		how to properly invoke them)
82		other                    --> use $URLGETTER directly, it must take
83		precisely two command-line arguments
84		(source URL and destination file name)

88		Date: 2002/01/28
89		Tag: blume-20020128-sparc-ccalls
90		Description:
91
92		- Fixed problem with calculation of "used" registers in sparc-c-calls.
93		- Make use of the allocParam argument in sparc-c-calls.

98		Tag: blume-20020128-allocParam
99		Description:
100
101		John Reppy:  Changes c-calls API to accept client-callback for
102		allocating extra stack space.
103		me: Corresponding changes to mlriscGen (using a dummy argument that
104		does not change the current behavior).

117		Tag: blume-20020128-retraction
118		Description:
119
120		0. Retracted earlier 110.38.  (The Release_110_38 tag has been replaced
121		with blume-Release_110_38-retracted.)
122
123		1. Fixed a problem with incorrect rounding modes in real64.sml.
124		(Thanks to Andrew Mccreight <andrew.mccreight@yale.edu>.)
125
126		2. A bug in ml-nlffigen related to the handling of unnamed structs, unions,
127		and enums fixed.  The naming of corresponding ML identifiers should
128		now be consistent again.

132		Date: 2002/01/27
133		Tag: leunga-20020127-nowhere
134		Description:
135
136		Added a target called nowhere in the configuration scripts.
137		Enabling this will build the MLRISC 'nowhere' tool (for translating
138		programs with where-clauses into legal SML code) during installation.

143		Tag: blume-Release_110_38-retracted
144		Description:
145
146		Call it a (working) release!  Version is 110.38. Bootfiles are ready.
147
148		README will be added later.
149
150		!!! NOTE:  Re-tagged as blume-Release_110_38-retracted. Original tag
151		(Release_110_38) removed.  Reason: Last-minute bug fixes.

155		Date: 2002/01/25
156		Tag: blume-20020125-ffi
157		Description:
158
159		A large number of tweaks and improvements to ml-nlffi-lib and
160		ml-nlffigen:
161
162		- ML represenation types have been streamlined
163		- getter and setter functions work with concrete values, not abstract
164		ones where possible
165		- ml-nlffigen command line more flexible (see README file there)
166		- some bugs have been fixed (hopefully)

171		Tag: george-20020124-risc-ra-interface
172		Description:
173
174		There is a dramatic simplification in the interface to the
175		register allocator for RISC architectures as a result of making
176		parallel copy instructions explicit.
177

179		Name: Matthias Blume
180		Date: 2002/01/22
181		Tag: blume-20020122-x86-ccalls
182		Description:
183
184		Bug fix for c-calls on x86 (having to do with how char- and
185		short-arguments are being handled).
