xlock is setgid (auth), but does not use the bsd.prog.mk build infrastructure,
so it needs manual definition of "mode_t _permit_setugid = S_ISGID". The other
setgid program in X11R6 is xterm (group utmp), but it is built using bsd.prog.mk
and automatically picks up the _permit_setugid variable.
- Add the aarch64 NEON code
- Remove use of ASM_HAVE_FUNC_DIRECTIVE. It is not relevant
for sparc64. Clang on ARM does not support .func
- Enable the GCC vector extensions and TLS on the other Clang
archs
diff from brad, ok miod@, kettenis@ for the arm64 part.
Fixup previous
As explained by matthieu@ the intent of this file is to track the latest
version available *upstream*, not the version we have. Here matthieu@
plans to merge the full update to xserver-21.1.25 etc soon.
