Janne Blomqvist d66d6d15f1 Use getentropy() for seeding PRNG ... The getentropy function, found on Linux, OpenBSD, and recently also FreeBSD, can be used to get random bytes to initialize the PRNG. It is similar to the traditional way of reading from /dev/urandom, but being a system call rather than a special file, it doesn't suffer from problems like running out of file descriptors, or failure when running in a container where /dev/urandom may not be available. Regtested on x86_64-pc-linux-gnu, Ok for trunk? 2018-08-13 Janne Blomqvist <jb@gcc.gnu.org> * configure.ac: Check for getentropy. * intrinsics/random.c (getosrandom): Use getentropy if available. * config.h.in: Regenerated. * configure: Regenerated.
