[LLVMdev] Puzzled by "set" in target description file
...arget description declares an instruction as below:
def MOVi2pieces : AI1x2<(outs GPR:$dst), (ins so_imm2part:$src), Pseudo,
"mov", " $dst, $src",
[(set GPR:$dst, so_imm2part:$src)]>;
I find 'set' declared in file TargetSelectDAG.td as
def set;
But if i modify it,
def set_try;
def MOVi2pieces : AI1x2<(outs GPR:$dst), (ins so_imm2part:$src), Pseudo,
"mov", " $dst, $src",
[(set_try GPR:$dst, so_imm2part:$src)]>;
tblgen will give a message...
