POSIX cares not one jot about Intel's CPU implementation, the assumption that memset is not async-signal safe because of something specific to x86 is ludicrous.

POSIX cares not one jot about Intel's CPU implementation, the assumption that memset is not async-signal safe because of something specific to x86 is ludicrous. As of IEEE Std 1003.1-2008, 2016 Edition memset() and lots of others beside are now Async-Signal safe, see http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2.... That's in contrast to IEEE Std 1003.1, 2004 Edition which has a much shorter list which excludes memset(), see http://pubs.opengroup.org/onlinepubs/007904975/functions/xsh_chap02_04.html http://pubs.opengroup.org/onlinepubs/007904975/functions/xsh...
