Chris Lattner f29cc88210 Revert the previous patch, which I didn't mean to check in. 
llvm-svn: 21226

Chris Lattner d3dc31009f Fix a minor bug (ORo didn't mark that it set CR0). 
Refactor how . instructions are handled.  In particular, instead of passing
the RC flag all the way up the inheritance hierarchy, just make a new tblgen
class 'DOT' which can be added to an instruction definition.

For example, instead of this:

-def AND  : XForm_6<31,  28, 0, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
-let Defs = [CR0] in
-def ANDo : XForm_6<31,  28, 1, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
-                   "and. $rA, $rS, $rB">;

We now have this:

+def AND  : XForm_6<31,  28, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
                    "and $rA, $rS, $rB">;

Chris Lattner b55f748b1a Branch instructions explicitly represent CRx in them. bEcause of this, encode 
them explicitly as well.

Misha Brukman 15b0fb5678 DForm_1, particularly used by store instructions, needs the immediate operand to 
be listed second as that is how the instructions are usually created (and is the
correct asm syntax) so that it's assembled correctly from its constituents

Misha Brukman 189f3dc8d2 There is only one field in an instruction, and that is `Inst', the final view of 
the instruction binary format, all others are simply operands and should not
have the `field' label
