unknown user pushed a change to branch zack/wip-sibcall-macros in repository glibc.

discards db7252fe67 WIP: Introduce pt-compat-stubs and use it to replace pt-vfork. adds 0f652f053e hurd: Fix build with latest htl adds fbce6f7260 Undefine attribute_hidden to fix benchtests adds d473f01520 Add SHT_X86_64_UNWIND to elf.h (bug 20079). adds 8d3f9e85cf Add narrowing subtract functions. adds 79962d89a9 hurd: Code style fixes adds ceb54b9b4f Fix errno values adds 8a07b0c43c Fix signed integer overflow in random_r (bug 17343). adds d0c5d731af Remove powerpc, sparc fdim inlines (bug 22987). new 0266547ef8 RFC: Introduce pt-compat-stubs and use it to replace pt-vfork.

This update added new revisions after undoing existing revisions. That is to say, some revisions that were in the old version of the branch are not in the new version. This situation occurs when a user --force pushes a change and generates a repository containing something like this:

* -- * -- B -- O -- O -- O (db7252fe67) \ N -- N -- N refs/heads/zack/wip-sibcall-macros (0266547ef8)

You should already have received notification emails for all of the O revisions, and so the following emails describe only the N revisions from the common base, B.

Any revisions marked "omits" are not gone; other references still refer to them. Any revisions marked "discards" are gone forever.

The 1 revisions listed above as "new" are entirely new to this repository and will be described in separate emails. The revisions listed as "adds" were already present in the repository and have only been added to this reference.
