示例1: make_pair
static std::pair<Value*, Value*> getMul64(IRBuilder<> &Builder,
Value *LHS, Value *RHS) {
Type *I32Ty = Builder.getInt32Ty();
Type *I64Ty = Builder.getInt64Ty();
Value *LHS_EXT64 = Builder.CreateZExt(LHS, I64Ty);
Value *RHS_EXT64 = Builder.CreateZExt(RHS, I64Ty);
Value *MUL64 = Builder.CreateMul(LHS_EXT64, RHS_EXT64);
Value *Lo = Builder.CreateTrunc(MUL64, I32Ty);
Value *Hi = Builder.CreateLShr(MUL64, Builder.getInt64(32));
Hi = Builder.CreateTrunc(Hi, I32Ty);
return std::make_pair(Lo, Hi);
