Ip lan to push this shortly because I think it's non-controversial and
it's more network-related than thread-related.
__errno_location should receive the same treatment, but there could be
references from assembler code, so I think it's best to delay that until
all code is gone from libpthread.
Tested on i686-linux-gnu and x86_64-linux-gnu. Built with
build-many-glibcs.py.
Thanks,
Florian

The existing definition in libc will be used instead.
The symbol was moved (that is, removed) using
scripts/move-symbol-to-libc.py.

From: Florian Weimer via Libc-alpha @ 2021-04-23 12:58 UTC (permalink / raw)
To: libc-alpha
The existing definition in libc will be used instead.
The symbol was moved (that is, removed) using
scripts/move-symbol-to-libc.py.
