cf9008afea Make it easier to find alpha stuff in doxygen, and fixup labeling 
of memory instructions in the assembly, to allow later linking
of traces with LLVM Value*s.

39edea8306 Fix 2005-05-12-Int64ToFP 
The issue is there is no unsigned -> double conversion, only signed.  So I
need to test the sign and do a different thing depending on it.  Ideally
this should be in a different BB, but in the mean time, I use a branch
free method.

aed06a0e92 Well, add support for ct* for 21264 only. 
21164 is broken until expand works.

5e177826fd Implement count leading zeros (ctlz), count trailing zeros (cttz), and count 
population (ctpop).  Generic lowering is implemented, however only promotion
is implemented for SelectionDAG at the moment.

More coming soon.

537332eba8 I was sure I had thought about this and there was a reason it should work. 
But it is entirely possible I am just crazy.

4a73c2cfdc Implement Value* tracking for loads and stores in the selection DAG. This enables one to use alias analysis in the backends. 
(TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*.  Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null.

857624f47a Remove support for ZERO_EXTEND_INREG. This pessimizes code, genering stuff 
like this:

        ldah $1,1($31)
        lda $1,-1($1)
        and $0,$1,$24

instead of this:

        zap $0,252,$24

To get this back, the selector should recognize the ISD::AND case where this
happens and emit the appropriate ZAP instruction.
