18    Description:
19    
20    1. X86 fixes/changes
21    
22       a.  The old code generated for SETcc was completely wrong.
23           The Intel optimization guide is VERY misleading.
24    
25    2. ALPHA fixes/changes
26    
27       a.  Added the instructions LDBU, LDWU, STB, STW as per Fermin's suggestion.
28       b.  Added a new mode byteWordLoadStores to the functor parameter to Alpha()
29       c.  Added reassociation code for address computation.

34    Tag: leunga-20000322-fix_x86_hppa_ra
35    Description:
36    
37    1. X86 fixes/changes
38    
39       a.  x86Rewrite bug with MUL3 (found by Lal)
40       b.  Added the instructions FSTS, FSTL
41    
42    2. PA-RISC fixes/changes
43    
44       a.  B label should not be a delay slot candidate!  Why did this work?
45       b.  ADDT(32, REG(32, r), LI n) now generates one instruction instead of two,
46           as it should be.
47       c.  The assembly syntax for fstds and fstdd was wrong.
48       d.  Added the composite instruction COMICLR/LDO, which is the immediate
49           operand variant of COMCLR/LDO.
50    
51    3. Generic MLRISC
52    
53       a.  shuffle.sml rewritten to be slightly more efficient
54       b.  DIV bug in mltree-simplify fixed (found by Fermin)
55    
56    4. Register Allocator
57    
58       a.  I now release the interference graph earlier during spilling.
59           May improve memory usage.

65    Description:
66    
67    1. Tools.registerStdShellCmdTool (from smlnj/cm/tool.cm) takes an
68    additional argument called "template" which is an optional string that
69    specifiel the layout of the tool command line.  See the CM manual for
70    explanation.
71    
72    2. A special-purpose tool can be "regisitered" by simply dropping the
73    corresponding <...>-tool.cm (and/or <...>-ext.cm) into the same
74    directory where the .cm file lives that uses this tool.  (The
75    behavior/misfeature until now was to look for the tool description
76    files in the current working directory.)  As before, tool description
77    files could also be anchored -- in which case they can live anywhere
78    they like.  Following the recent e-mail discussion, this change should
79    make it easier to have special-purpose tools that are shipped together
80    with the sources of the program that uses them.
