Subject: Add AT_RSEQ_* from Linux 6.3 to elf.h
Date: Wed, 17 May 2023 21:43:36 +0000 [thread overview]
Message-ID: <e0604ec6-dcd-189a-cd19-1b947dbe63a@codesourcery.com> (raw)
Linux 6.3 adds constants AT_RSEQ_FEATURE_SIZE and AT_RSEQ_ALIGN; add
them to glibc's elf.h. (Recall that, although elf.h is a
system-independent header, so far we've put AT_* constants there even
if Linux-specific, as discussed in bug 15794. So rather than making
any attempt to fix that issue, the new constants are just added there
alongside the existing ones.)
Tested for x86_64.
