Authored by JDevlieghere on Oct 9 2017, 4:41 AM.



This patch adds timestamp verification for swiftmodule files.

  • A new flag is provided to allows us to continue testing of the code for embedding the__swift_ast. (git doesn't maintain timestamps)
  • Adds a new test for fat (arm) binaries.

if the test is disabling the new functionality (-no-swiftmodule-timestamp) what is it testing?

I used this to verify my implementation locally, and figured I might as well upstream it as it covers two scenarios (arm & universal mach-o) not covered by the existing test. Let me know if you would leave this out or have it moved into in a separate commit.

the extra test is fine, I was just wondering if the test shouldn't be testing for the "Timestamp mismatch" warning.
