[LLVMdev] Error: Type constraint application shouldn't fail!
Hi list, I'm trying to match a particular pattern into the SDag which looks like this: // non-commutative multiplication def ncmul : SDNode<"ISD::MUL" , SDTIntBinOp, [SDNPAssociative]>; def mula_pat : PatFrag<(ops node:$a, node:$b), (add (ncmul (sext (i16 (extractelt node:$a, (i32 0)))), (sext (i16 (extractelt node:$b, (i32 1)))) ), (ncmul (sext (i16 (extractelt node:$a, (i32 1)))), (sext (i16 (extractelt node:$b, (i32 0)))) ) ) >; def ADDMULv : InstSP< (outs IntRegs:$dst), (ins IntRegs:$a, IntRegs:$b), "muladd $a, $b, $dst", [(set (i32 IntRegs:$dst), (mula_pat (v2i16 IntRegs:$a), (v2i16 IntRegs:$b)))]>; IntRegs is class with a type list of [i32, v2i16] But I get the following error when llvm building system try to generate the ISelector llvm[3]: Building Sparc.td DAG instruction selector implementation with tblgen vtInt: (vt:Other)<<P:Predicate_vtInt>> Type constraint application shouldn't fail!0 llvm-tblgen 0x081d6de7 1 llvm-tblgen 0x081d6b74 2 0x4001d400 __kernel_sigreturn + 0 3 libc.so.6 0x401b8a82 abort + 386 4 llvm-tblgen 0x0810a4ab 5 llvm-tblgen 0x0810a38f 6 llvm-tblgen 0x0810dd72 7 llvm-tblgen 0x080f8d98 8 llvm-tblgen 0x08176f49 9 llvm-tblgen 0x08184519 10 llvm-tblgen 0x081760e5 11 libc.so.6 0x401a1bd6 __libc_start_main + 230 12 llvm-tblgen 0x0804cb51 Any clue where it may come from ?
