19		Description:
20
21		Continued hacking on autoloading problem -- with success this time.
22		Also changed tool-plugin mechanism.  See new CM manual.

28		Description:
29
30		Some hacking to make autoloading faster.  Success for CMB, no success
31		so far for CM.  There is a reduced structure CM' that autoloads faster.
32		(This is a temporary, non-documented hack to be eliminated again when
33		the general problem is solved.)

38		Tag: blume-20001117-pickle-lib
39		Description:
40
41		1. Eliminated comp-lib.cm
42		2. Made pickle-lib.cm
43		3. Eliminated all uses of intset.sml (from comp-lib.cm)
44		4. Replaced all uses of intmap.{sig,sml} (from comp-lib.cm) with
45		equivalent constructs from smlnj-lib.cm (INtHashTable).
46		5. Point 4. also goes for those uses of intmap.* in MLRISC.
47		Duplicated intmap modules thrown out.
48		6. Hunted down all duplicated SCC code and replaced it with
49		equivalent stuff (GraphSCCFn from smlnj-lib.cm).
50		7. Rewrote Feedback module.
51		8. Moved sortedlist.sml into viscomp-lib.cm.  Eventually it
52		should be thrown out and equivalent modules from smlnj-lib.cm
53		should be used (IntRedBlackSet, IntListSet, ...).
54
55		Confirmed that compiler compiles to fixpoint.

60		Tag: leunga-20001110-new-x86-fp
61
62		A new x86 floating point code generator has been added.
63		By default this is turned off.  To turn this on, do:
64
65		CM.autoload "$smlnj/compiler.cm";
66		Compiler.Control.MLRISC.getFlag "x86-fast-fp" := true;
67
68		Changes:
69
70		1.  Changed FTAN to FPTAN so that the assembly output is correct.
71		2.  Changed the extension callback for FTANGENT to generate:
72
73		fptan
74		fstp  %st(0)
75		instead of
76		fptan
77		fstpl ftempmem
78
79		3.  Numerous assembly fixes for x86.
80
81		5.  Cleaned up the machine code output module x86/x86MC.sml and added
82		support for a whole bunch of instructions and addressing modes:
83
84		fadd/fsub/fsubr/fmul/fdiv/fdivr  %st, %st(n)
85		faddp/fsubp/fsubrp/fmulp/fdivp/fdivrp  %st, %st(n)
86		fadd/fsub/fsubr/fmul/fdiv/fdivr  %st(n), %st
87		fiadd/fisub/fisubr/fimul/fidiv/fidivr mem
88		fxch %st(n)
89		fld %st(n)
90		fst %st(n)
91		fst mem
92		fstp %st(n)
93		fucom %st(n)
94		fucomp %st(n)
95
96		All these are now generated when the fast fp mode is turned on.
97
98		6.  Removed the dedicated registers %st(0), ..., %st(7) from X86CpsRegs

103		Tag: blume-20001109-scc
104		Description:
105
106		Eliminated some code duplication:
107
108		1. Added "where" clause to GraphSCCFn in SML/NJ Library.
109		(Otherwise the functor is useless.)
110		2. Used GraphSCCFn where SCCUtilFun was used previously.
111		3. Got rid of SCCUtilFun (in comp-lib.cm).
