--- Comment #5 from Julian Seward <jsew...@acm.org> --- I'm somewhat concerned, at a fundamental level .. if I understand correctly, these instructions allow one to copy memory from one place to another (so why bother? Why not just do normal loads/stores?) but -- at least as implemented -- there's no way to tell Memcheck or any other tool, that the values in the destination area are derived from values in the source area. So you'll wind up with definedness false positives or negatives as a result of using them. Can you explain the background to the insns, what they are used for, etc, so we can see if there's an implementation that fits better in the instrumentation framework? -- You are receiving this mail because: You are watching all bug changes.
