[LLVMdev] How to calculate the address in TableGen?
Hello everyone,
I would like to ask a question about the address calculation in TableGen.
I replace a definition in MipsInstrInfo.td:
def : Pat<(i32 (extloadi16_a addr:$src)), (LHu addr:$src)>;
to:
def : Pat<(i32 (extloadi16_a addr:$src)), (OR (LBu addr:$src), (SLL (LBu addr:($src+1)), 8))>;
However, it failed to compiled. It seems that ($src+1) is a wrong representation in TableGen.
