hi all, i have 2 intrinsics that i want to insert them into my C code. def int_nema_lkp3: GCCBuiltin<"__builtin_nema_lkp3">,Intrinsic<[llvm_v4f32_ty], [llvm_v4f32_ty, llvm_v4f32_ty, llvm_v4f32_ty]>; def int_nema_updt: GCCBuiltin<"__builtin_nema_updt">,Intrinsic<[], [llvm_v4f32_ty]>; and the C sample code is main { float4 a,b,c,d; d=__builtin_nema_lkp3(a,b,c); /// if have hit jump after __builtin_nema_updt d= a*b+c; __builtin_nema_updt(d); return 0; } so i want the first intrinsic instruction to conditionally branch after the second intrinsic instruction. i have tried to do the same with with if - else code but this needs an extra variable that i don't want to exist. Should i do something like iterating the nodes to find where to jump??
