An alias set numbering maps alias sets to integer numbers, and that map is one-to-one. > If you want to have a number that is the same for all conflicting > memory references then you have to build the full conflict map and > partition it. > Likely not what you want? maybe > Why do you need alias-set numbers? We want to represent the alias set information as an extra subscript on memory accesses: for example, if we have A[10] and supposing that A is in alias set 6, this would be represented as "memory_access[6][10]". For B[3][4] with base array B in alias set 7 and 8, we would represent this as "memory_access[7][3][4] or memory_access[8][3][4]". The data dependence test that we currently have in the graphite branch would work with alias sets represented by an extra dimension to the array dimensions. Sebastian
