[LLVMdev] Load/Store Instruction Error

[Ramin Guner]

Hi all,

I  started to write an LLVM backend for custom CPU. I created XXXInstrInfo
but there are some problems. I searched for it but I couldn't find
anything. Can anyone help me?

include "XXXInstrFormats.td"
def simm16 : Operand<i32> {
    let DecoderMethod = "DecodeSimm16";
}
def mem : Operand<i32> {
    let PrintMethod = "printMemOperand";
    let MIOperandInfo = (ops GPRegs, GPRegs);
    let EncoderMethod = "getMemEncoding";
}
def addr : ComplexPattern<i32, 2, "SelectAddr", [frameindex],
[SDNPWantParent]>;

def LDRAM : FG1<0b000001, (outs GPRegs:$dst), (ins mem:$src), "ldram
$dst,$src", [(set GPRegs:$dst, (load addr:$src))]>;
def STRAM : FG1<0b000010, (outs), (ins GPRegs:$src, mem:$dst), "stram
$dst,$src", [(store GPRegs:$src, addr:$dst)]>;
def ADD : FG2<0b000000, (outs GPRegs:$dst), (ins GPRegs:$src1,
GPRegs:$src2), "add $dst,$src1,$src2", [(set GPRegs:$dst, (add
GPRegs:$src1, GPRegs:$src2))]>;

Error Message:
LDRAM: (set GPRegs:{i32:f32}:$dst, (ld:{i32:f32}
addr:iPTR:$src)<<P:Predicate_unindexedload>><<P:Predicate_load>>)

Thanks in advance.
