What _is_ clear is that the confusion, finger-pointing and debate will persist until the overhead (actually the difference in simulation overhead between the opcodes chosen by the compiler [80-bit] and the opcodes substituted by memcheck [64-bit]) is measured numerically, analyzed and documented. Then perhaps there can be an option so that informed users can choose. -- |
