[LLVMdev] Instruction Encodings in TableGen
...perands are translated into the encoding fields. Can someone please explain the following snippet from the PPC back-end. The AND instruction in PPC is defined as: 1011 def AND : XForm_6<31, 28, (outs GPRC:$rA), (ins GPRC:$rS, GPRC:$rB), 1012 "and $rA, $rS, $rB", IntSimple, 1013 [(set GPRC:$rA, (and GPRC:$rS, GPRC:$rB))]>; Okay, so rA, rS, and rB are register operands. The TableGen classes are defined as: 315 class XForm_base_r3xo_swapped 316 <bits<6> opcode, bits<10> xo, dag OOL, dag IOL, string asmstr, 317 Ins...

[LLVMdev] Optimization issue for target's offset field of load operation in DAGSelection
I am working on an experimental target and trying to make sure that the load offset field is used to the best way. There appears to be some control over the architecture's offset range and whether the offset is too large and needs to be lowered/converted into a separate sequence of operations in DAGSelection? Can someone point me to what might be the case? For example, the difference between
