llvm dev - Sep 2010 - [LLVMdev] AliasAnalysis Doubt.

Hi All,

  I'm trying to use the inbuilt AliasAnalysis function for one of my
projects. Im trying to find out if a pair of load and store alias each
other. It would be helpful if somebody could point out the right way to do
this.

 Example :   %13 = load i32* %12, align 4
                   store i32 30, i32* %4, align 4

                  So in the above example i'm trying to find out if the
values %4 and %13 alias. (Both these values are getelementptr
instructions.).

  Thanks,
  Rohith.
