There is an error “use of unknown builtin”
Hello，everyone.
I am very embarrassed to ask such a simple question.
I want to add an intrinsics(named max_qb) in x86 backend.
In include/llvm/IR/IntrinsicsX86.td, I add a intrinsics (GCCBuiltin).
In clang( BuiltinsX86.def ), I add a BUILTIN.
And in x86 backend , I change :
the X86InstrInfo.td to add def X86max_qb_flag ,
X86InstrArithmetic.td to add define of instruction ,
X86ISelLowering.cpp to
