Bill Wendling	59a1021dc6	* The DSE code that tested for overlapping needed to take into account the fact ... that one of the numbers is signed while the other is unsigned. This could lead to a wrong result when the signed was promoted to an unsigned int. * Add the data layout line to the testcase so that it will test the appropriate thing.

Bill Wendling	72b390743d	PR9561: A store with a negative offset (via GEP) could erroniously say that it ... completely overlaps a previous store, thus mistakenly deleting that store. Check for this condition. llvm-svn: 128319	2011-03-26 01:20:37 +00:00
