Hi all, I would like to be sure that Tablegen still does not support completely separate multiple instruction generation, and the only way is to write costume code (may be in TargetISelDAGToDAG class) to get the needed result. Dear Tom, do you found other solution (using Tablegen tool) for this?

Hi, I'm trying to create a Pattern that looks something like this: def my_inst : Instruction < let OutOperandList = (outs REG:$dst); let InOperandList = (ins imm:$src); let Uses = [R0]; > def int_my_intrinsic : Intrinsic < [llvm_float_ty], [llvm_i32_ty, llvm_i32_ty, llvm_i32_ty], [] >; def : Pattern < (int_my_intrinsic imm:$a, imm:$b, imm:$c), [(set R0, (MOV_IMM
