[LLVMdev] llvm-tblgen for ARMInstrFormats.td with !if(a,b,c)

[GangRyung Uh]

Hi,

    I wonder whether I can conditionally set AsmString in class sI. For
instance, I would like to know whether it is possible to establish some int
or bit operator to check whether bits<4> p is 14. What I would like to do
is to set AsmString as follows,

    class sI<...> :InstARM<....> {
       ...
      let AsmString = !if(some operator, !strconcat(ppc, "${s}", asm),
                                  !strconcat(ppc, "${p}${s}", asm);
       ...
    }

Thanks,
