[LLVMdev] a very strange question about adding new instrinsic.
...mycase.ll -o mycase.bc
llc -march=ppc32 mycase.bc -o mycase.s
I get in mycase.s :
stwx 4, 5, 3
62 la 3, .str at l(8)
63 mytest <----my test instruction.
64 creqv 0, 0, 0
65 li 30, 0
BUT when I implement them to my target, llc error:
llc:
/backup/AndesCC/llvm/include/llvm/Support/Casting.h:199: typename
llvm::cast_retty<To, From>::ret_type llvm::cast(const Y&)
[with X = llvm::ConstantSDNode, Y = llvm::SDValue]: Assertion
`isa<X>(Val) && "cast<Ty>() argument of
incompatible type!"' failed.
Why? I
miss so...
