Sir, Given code like:> > X = add int Y, 1 > Z = mul int X, 17while I iterate over the operands of the first instruction i want to print the variable x ,as well as the constant 1 and while i iterate over the second instruction i want to print variable x and constant 17. what should I do? thanking you, yours sincerely, anubham suresh TU-Darmstadt --- llvmdev-request at cs.uiuc.edu wrote:> Send LLVMdev mailing list submissions to > llvmdev at cs.uiuc.edu > > To subscribe or unsubscribe via the World Wide Web, > visit > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev > or, via email, send a message with subject or body > 'help' to > llvmdev-request at cs.uiuc.edu > > You can reach the person managing the list at > llvmdev-owner at cs.uiuc.edu > > When replying, please edit your Subject line so it > is more specific > than "Re: Contents of LLVMdev digest..." > > > Today's Topics: > > 1.
