Ok, thanks for the heads up, I'm now trying to figure out the problems with offsets for packed structs in BTF, also there is the flatenning of arrays that I'd like to see discussed. i.e.: int array[5][5]; is correctly expressed in DWARF and allows reconstructing the original data structure, while BTF is encoding it in such a way that it comes back reconstructed as: int array[25]; - Arnaldo
