19    Description:
20    
21    A quick fix for a problem with GenSML (in the pgraph-util library):
22    Make generation of toplevel "local" optional.  (Strictly speaking,
23    signature definitions within "local" are not legal SML.)
24    
25    Other than that: updates to INSTALL and cm/TODO.

31    Description:
32    
33    0. Version number has been bumped to 110.38.1.  NEW BOOTFILES!!!
34    
35    1. The installer (config/install.sh) has gotten smarter:
36    
37         - Configuration options are a bit easier to specify now
38           (in config/targets).
39         - Bug in recognizing .tar.bz2 files fixed.
40         - Installer automatically resolves dependencies between
41           configuration options (e.g., if you ask for eXene, you will
42           also get cml -- regardless whether you asked for it or not).
43         - Installer can run in "quieter mode" by setting the environment
44           variable INSTALL_QUIETLY to "true".  "Quieter" does not mean
45           "completely silent", though.
46         - Build HashCons library as part of smlnj-lib.
47    
48    2. A new scheme for assigning persistent identifiers to compilation
49       units (and, by extension, to types etc.) has been put into place.
50       This fixes a long-standing bug where types and even dynamic values
51       can get internally confused, thereby compromising type safety
52       (abstraction) and dynamic correctness.  See
53    
54         http://cm.bell-labs.com/cm/cs/who/blume/pid-confusion.tgz
55    
56       for an example of how things could go wrong until now.
57    
58       The downside of the new scheme is that pids are not quite as
59       persistent as they used to be: CM will generate a fresh pid
60       for every compilation unit that it thinks it sees for the first
61       time.  That means that if you compile starting from a clean, fresh
62       source tree at two different times, you end up with different
63       binaries.
64    
65       Cutoff recompilation, however, has not been compromised because
66       CM keeps pid information in special caches between runs.

72    Description:
73    
74    Compilers that generate assembly code may produce  global labels
75    whose value is resolved at link time. The various peephole optimization
76    modules did not take this in account.
77    
78    TODO. The Labels.addrOf function should really return an option
79    type so that clients are forced to deal with this issue, rather
80    than an exception being raised.

86    Description:
87    
88    1. A bug fix from Allen.
89    
90        A typo causes extra fstp %st(0)'s to be generated at compensation
91        edges, which might cause stack underflow traps at runtime.  This
92        occurs in fft where there are extraneous fstps right before the 'into'
93        trap instruction (in this case they are harmless since none of the
94        integers overflow.)
95    
96    2. Pulled out various utility modules that were embedded in the modules
97       of the register allocator. I need these modules for other purposes, but
98       they are not complete enough to put into a library (just yet).

103    Description:
104    
105    1. C-calls on Sparc needlessly allocated a huge chunk (96 bytes)
106       of extra stack space by mistake.  Fixed.
107    
108    2. Bug in logic of handling of command-line options in ml-nlffigen fixed.

115    
116       MLRISC bug fixes:
117       1. Fixed a bindings computation bug in the 'nowhere' program generator tool.
118       2. MachineInt.fromString was negating its value.

124    Description:
125    
126    - Added somewhat detailed installation instructions (file INSTALL).
127    - Fixed curl-detection bug in config/install.sh.
128    - It is now possible to select the URL getter using the URLGETTER
129      environment variable:
130    
131          not set / "unknown"      --> automatic detection (script tries wget,
132                                       curl, and lynx)
133          "wget" / "curl" / "lynx" --> use the specified program (script "knows"
134                                       how to properly invoke them)
135          other                    --> use $URLGETTER directly, it must take
136                                       precisely two command-line arguments
137                                       (source URL and destination file name)

145    - Fixed problem with calculation of "used" registers in sparc-c-calls.
146    - Make use of the allocParam argument in sparc-c-calls.

154    John Reppy:  Changes c-calls API to accept client-callback for
155    allocating extra stack space.
156    me: Corresponding changes to mlriscGen (using a dummy argument that
157        does not change the current behavior).

171    Description:
172    
173    0. Retracted earlier 110.38.  (The Release_110_38 tag has been replaced
174       with blume-Release_110_38-retracted.)
175    
176    1. Fixed a problem with incorrect rounding modes in real64.sml.
177       (Thanks to Andrew Mccreight <andrew.mccreight@yale.edu>.)
178    
179    2. A bug in ml-nlffigen related to the handling of unnamed structs, unions,
180       and enums fixed.  The naming of corresponding ML identifiers should
181       now be consistent again.

187    Description:
188    
189       Added a target called nowhere in the configuration scripts.
190       Enabling this will build the MLRISC 'nowhere' tool (for translating
191       programs with where-clauses into legal SML code) during installation.
