19    Description:
20    
21    Changes to implement the omit-frame-pointer optimization to support
22    raw C calls. For now, there is only support on the Intel x86, but
23    other architectures will follow as more experience is gained with this.

30    Description:
31    
32    I made into "proxy libraries" all libraries that qualify for such a
33    change.  (A qualifying library is a library that has another library or
34    groups as its sole member and repeats that member's export list
35    verbatim.  A proxy library avoids this repetition by omitting its export
36    list, effectively inheriting the list that its (only) member exports.
37    See the CM manual for more explanation.)
38    The main effect is that explicit export lists for these libraries
39    do not have to be kepts in sync, making maintenance a bit easier.
40    
41    I also added copyright notices to many .cm-files.
42    
43    Last but not least, I made a new set of bootfiles.

49    Description:
50    
51    0. John merged pending changes to $/smlnj-lib.cm
52    
53    1. Allen's previous change accidentally backed out of one of Lal's
54       earlier changes.  I undid this mistake (re-introducing Lal's change).
55    
56    2. I used the new topOrder' function from graph-scc.sml (from $/smlnj-lib.cm)
57       within the compiler where applicable.  There is some code simplification
58       because of that.
59    
60    3. The "split" phase (in FLINT) is now part of the default list of phases.
61       Compiler.Control.LambdaSplitting.* can be used to globally control the
62       lambda-splitting (cross-module-inlining) engine.  In addition to that,
63       it can now also be controlled on a per-source basis: CM has been taught
64       a new tool parameter applicable to ML source files.
65    
66       - To turn lambda-splitting off completely:
67            local open Compiler.Control.LambdaSplitting in
68                val _ = set Off
69            end
70       - To make "no lambda-splitting" the global default (but allow per-source
71         overriding); this is the initial setting:
72            local open Compiler.Control.LambdaSplitting in
73                val _ = set (Default NONE)
74            end
75       - To make "lambda-splitting with aggressiveness a" the global default
76         (and allow per-source overriding):
77            local open Compiler.Control.LambdaSplitting in
78                val _ = set (Default (SOME a))
79            end
80    
81       - To turn lambda-splitting off for a given ML souce file (say: a.sml)
82         write (in the respective .cm-file):
83            a.sml (lambdasplitting:off)
84       - To turn lambda-splitting for a.sml on with minimal aggressiveness:
85            a.sml (lambdasplitting:on)
86       - To turn lambda-splitting for a.sml on with aggressiveness <a> (where
87         <a> is a decimal non-negative integer):
88            a.sml (lambdasplitting:<a>)
89       - To turn lambda-splitting for a.sml on with maximal aggressiveness:
90            a.sml (lambdasplitting:infinity)
91       - To use the global default for a.sml:
92            a.sml (lambdasplitting:default)
93         or simply
94            a.sml

100    Description:
101    
102      MLRISC features.
103    
104      1. Fix to CMPXCHG instructions.
105      2. Changed RA interface to allow annotations in callbacks.
106      3. Added a new method to the stream interface to allow annotations updates.

111    Tag: blume-20010501-pcedittmp
112    Description:
113    
114    Changed install.sh to use the current working directory instead of
115    /usr/tmp for a temporary file (pcedittmp).  The previous choice
116    of /usr/tmp caused trouble with MacOS X because of file premission
117    problems.

122    Tag: blume-20010420-inMLflag
123    Description:
124    
125     - added vp_limitPtrMask to vproc-state.h
126       (for use by the raw-C-calls mechanism to implement proper interrupt
127        handling)
128     - made the ML compiler aware of various data-structure offsets so it
129       can generate code for accessing the vp_inML flag and vp_limitPtrMask
130     - tweaked mlriscGen.sml to have it emit interrupt-handling code for
131       raw C-calls
