19    Description:
20    
21    Made install.sh use file config/targets.customized if it exists, falling
22    back to config/targets if it doesn't.  This way one can have a customized
23    version of the targets file without touching the "real thing", thus
24    eliminating the constant fear of accidentally checking something bogus
25    back into the CVS repository...  (File config/targets.customized must
26    not be added to the repository!)

32    Description:
33    
34    1. Bug fix in ml-nlffigen; now (hopefully) correctly handling
35       struct returns.
36    2. Added src/ml-nlffi-lib/Doc/mini-tutorial.txt.  This is some very
37       incomplete, preliminary documentation for NLFFI.

43    Description:
44    
45    Some bugs in install script fixed.
46    
47    In addition to that I also made a slight change to the NLFFI API:
48    Functors generated by ml-nlffigen now take the dynamic library as a
49    straight functor argument, not as a suspended one.  (The original
50    functor code used to force the suspension right away anyway, so there
51    was nothing gained by this complication of the interface.)

56    Tag: blume-20010511-ml-nlffi
57    Description:
58    
59    I finally took the plunge and added my new FFI code to the main
60    repository.  For x86-linux it is now ready for prime-time.
61    
62    There are two new subdirectories of "src":
63    
64      - ml-nlffi-lib:
65           The utility library for programs using the FFI interface.
66           Here is the implementation of $/c.cm and its associated low-level
67           partners $/c-int.cm and $/memory.cm.
68      - ml-nlffigen:
69           A stand-alone program for generating ML glue code from C source
70           code.
71    
72    Building ml-nlffigen requires $/ckit-lib.cm.
73    
74    The config/install.sh script has been updates to do the Right Thing
75    (hopefully).
76    
77    Notice that the source tree for the C-Kit will not be put under "src"
78    but directly under the installation root directory.  (This is the
79    structure that currently exists on the CVS server when you check out
80    module "sml".)  Fortunately, config/install.sh knows about this oddity.
81    
82    Bugs: No documentation yet.

87    Tag: blume-20010509-cpscontract
88    Description:
89    
90    Fixed a bug in the accounting code in cpsopt/contract.sml.  (The
91    wrapper/unwrapper elimination did not decrement usage counts and some
92    dead variables got overlooked by the dead-up logic.)

98    Description:
99    
100    Changes to implement the omit-frame-pointer optimization to support
101    raw C calls. For now, there is only support on the Intel x86, but
102    other architectures will follow as more experience is gained with this.

108    Tag: blume-20010507-proxies
109    Description:
110    
111    I made into "proxy libraries" all libraries that qualify for such a
112    change.  (A qualifying library is a library that has another library or
113    groups as its sole member and repeats that member's export list
114    verbatim.  A proxy library avoids this repetition by omitting its export
115    list, effectively inheriting the list that its (only) member exports.
116    See the CM manual for more explanation.)
117    The main effect is that explicit export lists for these libraries
118    do not have to be kepts in sync, making maintenance a bit easier.
119    
120    I also added copyright notices to many .cm-files.
121    
122    Last but not least, I made a new set of bootfiles.

127    Tag: blume-20010504-cm-lsplit
128    Description:
129    
130    0. John merged pending changes to $/smlnj-lib.cm
131    
132    1. Allen's previous change accidentally backed out of one of Lal's
133       earlier changes.  I undid this mistake (re-introducing Lal's change).
134    
135    2. I used the new topOrder' function from graph-scc.sml (from $/smlnj-lib.cm)
136       within the compiler where applicable.  There is some code simplification
137       because of that.
138    
139    3. The "split" phase (in FLINT) is now part of the default list of phases.
140       Compiler.Control.LambdaSplitting.* can be used to globally control the
141       lambda-splitting (cross-module-inlining) engine.  In addition to that,
142       it can now also be controlled on a per-source basis: CM has been taught
143       a new tool parameter applicable to ML source files.
144    
145       - To turn lambda-splitting off completely:
146            local open Compiler.Control.LambdaSplitting in
147                val _ = set Off
148            end
149       - To make "no lambda-splitting" the global default (but allow per-source
150         overriding); this is the initial setting:
151            local open Compiler.Control.LambdaSplitting in
152                val _ = set (Default NONE)
153            end
154       - To make "lambda-splitting with aggressiveness a" the global default
155         (and allow per-source overriding):
156            local open Compiler.Control.LambdaSplitting in
157                val _ = set (Default (SOME a))
158            end
159    
160       - To turn lambda-splitting off for a given ML souce file (say: a.sml)
161         write (in the respective .cm-file):
162            a.sml (lambdasplitting:off)
163       - To turn lambda-splitting for a.sml on with minimal aggressiveness:
164            a.sml (lambdasplitting:on)
165       - To turn lambda-splitting for a.sml on with aggressiveness <a> (where
166         <a> is a decimal non-negative integer):
167            a.sml (lambdasplitting:<a>)
168       - To turn lambda-splitting for a.sml on with maximal aggressiveness:
169            a.sml (lambdasplitting:infinity)
170       - To use the global default for a.sml:
171            a.sml (lambdasplitting:default)
172         or simply
173            a.sml

179    Description:
180    
181      MLRISC features.
182    
183      1. Fix to CMPXCHG instructions.
184      2. Changed RA interface to allow annotations in callbacks.
185      3. Added a new method to the stream interface to allow annotations updates.

190    Tag: blume-20010501-pcedittmp
191    Description:
192    
193    Changed install.sh to use the current working directory instead of
194    /usr/tmp for a temporary file (pcedittmp).  The previous choice
195    of /usr/tmp caused trouble with MacOS X because of file premission
196    problems.
