https://reviews.llvm.org/D51197 Currently, IRTranslator (and GISel) seems to be arbitrarily picking which overflow intrinsics get mapped into opcodes which either have a carry as an input or not. For intrinsics such as Intrinsic::uadd_with_overflow, translate it to an opcode (G_UADDO) which doesn't have any carry inputs (similar to LLVM IR). This patch adds 4 missing opcodes for completeness - G_UADDO, G_USUBO, G_SSUBE and G_SADDE. llvm-svn: 340865 |
