...t that doesn't generate. I'm currently trying to create a
class containing the ins and outs dags, using if(eq()) extensively, so that
the multiclass template for the instructions is a single line. Code
follows (probably not correct due to name mangling).
class IO_MultSrc<bits<2> op0Type, RegisterClass Src0RC> {
dag insDefault = !if(!eq(op0Type, 0b01),
(ins SpecialReg:$dst, Src0RC:$a),
(ins Src0RC:$a));
...
}
multiclass MultSrc1Spec<bits<5> subOpcode, bits<2> op0t, string opcodeStr,
RegisterClass RegType> {...
