19    Description:
20    
21    Fixed a bug in the accounting code in cpsopt/contract.sml.  (The
22    wrapper/unwrapper elimination did not decrement usage counts and some
23    dead variables got overlooked by the dead-up logic.)

29    Description:
30    
31    Changes to implement the omit-frame-pointer optimization to support
32    raw C calls. For now, there is only support on the Intel x86, but
33    other architectures will follow as more experience is gained with this.

40    Description:
41    
42    I made into "proxy libraries" all libraries that qualify for such a
43    change.  (A qualifying library is a library that has another library or
44    groups as its sole member and repeats that member's export list
45    verbatim.  A proxy library avoids this repetition by omitting its export
46    list, effectively inheriting the list that its (only) member exports.
47    See the CM manual for more explanation.)
48    The main effect is that explicit export lists for these libraries
49    do not have to be kepts in sync, making maintenance a bit easier.
50    
51    I also added copyright notices to many .cm-files.
52    
53    Last but not least, I made a new set of bootfiles.

58    Tag: blume-20010504-cm-lsplit
59    Description:
60    
61    0. John merged pending changes to $/smlnj-lib.cm
62    
63    1. Allen's previous change accidentally backed out of one of Lal's
64       earlier changes.  I undid this mistake (re-introducing Lal's change).
65    
66    2. I used the new topOrder' function from graph-scc.sml (from $/smlnj-lib.cm)
67       within the compiler where applicable.  There is some code simplification
68       because of that.
69    
70    3. The "split" phase (in FLINT) is now part of the default list of phases.
71       Compiler.Control.LambdaSplitting.* can be used to globally control the
72       lambda-splitting (cross-module-inlining) engine.  In addition to that,
73       it can now also be controlled on a per-source basis: CM has been taught
74       a new tool parameter applicable to ML source files.
75    
76       - To turn lambda-splitting off completely:
77            local open Compiler.Control.LambdaSplitting in
78                val _ = set Off
79            end
80       - To make "no lambda-splitting" the global default (but allow per-source
81         overriding); this is the initial setting:
82            local open Compiler.Control.LambdaSplitting in
83                val _ = set (Default NONE)
84            end
85       - To make "lambda-splitting with aggressiveness a" the global default
86         (and allow per-source overriding):
87            local open Compiler.Control.LambdaSplitting in
88                val _ = set (Default (SOME a))
89            end
90    
91       - To turn lambda-splitting off for a given ML souce file (say: a.sml)
92         write (in the respective .cm-file):
93            a.sml (lambdasplitting:off)
94       - To turn lambda-splitting for a.sml on with minimal aggressiveness:
95            a.sml (lambdasplitting:on)
96       - To turn lambda-splitting for a.sml on with aggressiveness <a> (where
97         <a> is a decimal non-negative integer):
98            a.sml (lambdasplitting:<a>)
99       - To turn lambda-splitting for a.sml on with maximal aggressiveness:
100            a.sml (lambdasplitting:infinity)
101       - To use the global default for a.sml:
102            a.sml (lambdasplitting:default)
103         or simply
104            a.sml

110    Description:
111    
112      MLRISC features.
113    
114      1. Fix to CMPXCHG instructions.
115      2. Changed RA interface to allow annotations in callbacks.
116      3. Added a new method to the stream interface to allow annotations updates.

121    Tag: blume-20010501-pcedittmp
122    Description:
123    
124    Changed install.sh to use the current working directory instead of
125    /usr/tmp for a temporary file (pcedittmp).  The previous choice
126    of /usr/tmp caused trouble with MacOS X because of file premission
127    problems.

132    Tag: blume-20010420-inMLflag
133    Description:
134    
135     - added vp_limitPtrMask to vproc-state.h
136       (for use by the raw-C-calls mechanism to implement proper interrupt
137        handling)
138     - made the ML compiler aware of various data-structure offsets so it
139       can generate code for accessing the vp_inML flag and vp_limitPtrMask
140     - tweaked mlriscGen.sml to have it emit interrupt-handling code for
141       raw C-calls
