Hello,

in Kali we are providing many images for ARM devices and some of the ARM
devices that we support have support for the LSE (Large System Extensions)
atomics. We would like to be able use a version of glibc with LSE support
enabled to see whether we can get better performances.

Ubuntu is already shipping a libc6-lse package on arm64 and it would be
nice if Debian could do the same. Balint Reczey (in CC) implemented the
support in Ubuntu, maybe he can share some hints on what's involved and
whether we should expect some related issues.

The patch used by Ubuntu looks like this one:
https://git.launchpad.net/ubuntu/+source/glibc/commit/?id=d38433a40db82a14c006bb9f411d9fc22b594fa4
(except the hunk on debian/testsuite-xfail-debian.mk which is the other
change in that same upload)

Can you consider applying a similar change?

Thank you in advance for your feedback.

Since glibc 2.31-0experimental2, Debian supports LSE on arm64
transparently using the -moutline-atomics option of GCC. Therefore there
is no plan to add a libc6-lse package in Debian (see bug #956418 for
the corresponding discussion).

I am therefore closing the bug.
