[LLVMdev] On semantics of add instruction - nsw,nuw flags
Hi, I am trying to understand the semantics of Instructions in llvm. Are the following instructions semantically same? * %add2 = add nsw i32 %add, %add1 %add3 = add i32 %add, %add1* Based on my understanding from the Language Reference Manual, I think they are different. But then why is the *gvn* pass detecting *%add3* as redundant and deleting it? Your views are appreciated. Rekha
