[LLVMdev] TableGen question
Hi,
In tablegen file inside class we have variables declared inside a
class. Say in PPC there is this
class BForm<bits<6> opcode, bit aa, bit lk, dag OOL, dag IOL, string asmstr>

bits<7> BIBO; // 2 bits of BI and 5 bits of BO.
bits<3> CR;
bits<14> BD;
How does the generator match each variable against an operand?
For the corresponding PPCGenMCCodeEmitter.inc for this the entry is
// op: BIBO
op = getMachineOpValue(MI, MI.getOp...
