             Bug #: 55376

           Summary: [asan] libsanitizer/README.gcc must contain the exact

                    steps to do code changes and to port code from

                    upstream

    Classification: Unclassified

           Product: gcc

           Version: unknown

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: other

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: konstantin.s.serebry...@gmail.com

                CC: dseke...@redhat.com, dvyu...@google.com,

We need to document the libsanitizer update process in libsanitizer/README.gcc



Few things to cover:



- The changes need to be approved by one of the maintainers (or is it obvious)?

- Except for *really* trivial changes all patches should go through the

upstream tree first. 

- When updating from upstream, the comment header should be tampered with (oh,

my)

- Ideally, we need to have a fully automated script to grab the upstream

changes (including new/deleted/moved files, etc). Suggestions here? 

- What is the testing procedure when updating from upstream? (e.g. how do we

avoid regressions on the platforms to which the maintainers have no access?)
