Commit Message

Adhemerval Zanella Netto March 16, 2021, 8:04 p.m. UTC 
The libc version is identical and built with same flags.  Both aarch64
and nios2 also requires to export __send.  It was done previously with
the HAVE_INTERNAL_SEND_SYMBOL (which forced the symbol creation),
however it is simpler to add them on the architecture specific Version
script snippet.

Checked on x86_64-linux-gnu and i686-linux-gnu.

In other cases, we have said that doing this would require adding a
__send@GLIBC_2.34 symbol (which is what my patched
move-symbol-to-libc.py script does).

However, I think we can turn this into a compat symbol in this case.
All __send callers are internal to libc, so we don't need
__send@GLIBC_PRIVATE, just a hidden proto.

Thanks,
Florian

One more comment: Please also remove:

sysdeps/unix/sysv/linux/aarch64/sysdep.h:# undef HAVE_INTERNAL_SEND_SYMBOL
sysdeps/unix/sysv/linux/nios2/sysdep.h:# undef HAVE_INTERNAL_SEND_SYMBOL

Thanks,
