Hi,
We don't have RNG instructions, and calling _sparcv9_random() causes
SIGILL and debug tools (i.e. gdb and mdb) stops when libcrypto.so is
loaded (at _init()).
% mdb `which openssl`
> ::run
mdb: stop on SIGILL
mdb: target stopped at:
libcrypto.so.1.0.0`_sparcv9_random+4: random %d8
Without those debugging tools, it's very hard to do any debugging, and
we would like the call to be removed.
The following suggested fix seems to fix the problem we are having with
the debugging tools.
