18    Description:
19      Updated mlyacc.tex sections 5 and 7 for SML '97 and CM.
20      Updated all three examples in src/ml-yacc/examples to run
21      under 110.* using CM.make.

27    Description:
28    
29      This update synchronizes my repository with Yale's.  Most of these
30    changes, however, do not affect SML/NJ at all (the RA is an exception).
31    
32    1. Register Allocator
33    
34       a. An improvement in the interference graph construction:
35          Given a copy
36    
37                s <- t
38    
39          no interference edge between s and t are added for this definition of s.
40    
41       b. I've added two new spill heuristic modules that Fermin and I developed
42          (in the new library RA.cm). These are unused in SML/NJ but maybe
43          useful for others (Moby?)
44    
45    2. X86
46    
47       a. Various fixes in the backend provided by Fermin [C--] and Lal.
48    
49    3. Alpha
50    
51       a. Added the BSR instruction and code generation that goes with it [C--]
52       b. Other fixes too numerous to recount provided by Fermin [C--]
53    
54    4. Regmaps
55    
56       a. The regmaps are not initialized with the identity physical bindings
57          at creation time.  This is unneeded.
58    
59    5. MLRISC Optimizations
60    
61       a. The DJ-Graph module can now compute the iterated dominance frontiers
62          intersects with liveness incrementally in linear time! Woohoo!
63          This is now used in my new SSA construction algorithm.
64    
65       b. THe branch reorganization module is now smarter about linear chains of
66          basic blocks.

73    Description:
74    
75    Changed install.sh script to handle archive files without version number
76    and to use "boot.<arch>-<os>" instead of "sml.boot.<arch>-<os>" for the
77    name of the boot file archive.

86    
87    2. Updated src/config/version to 110.27

96    
97    1.  Yet another fix for x86 assembly for idivl, imull, mull and friends.
98    
99    2.  Miscellaneous improvements to MLRISC (unused in sml/nj)

104    Tag: monnier-20000406-branch-handling
105    Description:
106    
107    Improved handling of branches (mostly those generated from
108    polymorphic equality), removed switchoff and changed the
109    default optimization settings (more cpsopt and less flintopt).

135    Description:
136    
137    This update just merges three minor cosmetic updates to CM's sources
138    to get ready for the 110.27 code freeze on Friday.  No functionality
139    has changed.

144    Tag: leunga-20000404-x86-asm
145    Description:
146    
147    1.  Fixed a problem in X86 assembly.
148    
149        Things like
150    
151           jmp %eax
152           jmp (%eax)
153    
154        should be output as
155    
156           jmp *%eax
157           jmp *(%eax)
158    
159    2.  Assembly output
160    
161          Added a new flag
162    
163              "asm-indent-copies" (default to false)
164    
165          When this flag is on, parallel copies will be indented an extra level.
