Because there is a shortcut. VIS2-capable CPUs are excused from
libdevinfo voodoo and USIII is VIS2-capable CPU. Because all so-far
observed VIS2-capable CPUs has identical qualities from OpenSSL
viewpoint. VIS2 capability is determined with sysinfo(SI_ISALIST).

Can't you write following yourself:
#include <libdevinfo.h>
static int walk_nodename(di_node_t node, void *p)
{ return DI_WALK_CONTINUE; }
int main()
{
di_node_t root_node;
if ((root_node = di_init("/",DINFOSUBTREE))!=DI_NODE_NIL)
{
di_walk_node(root_node,DI_WALK_SIBFIRST,
NULL,walk_nodename);
di_fini(root_node);
}
}
Link with -ldevinfo - works, with -ldevinfo -lmalloc - crashes.

Pleeeeeeeaaaaase.
It's also possible to switch to the detection procedure used on Linux
(in which case it might have to be refined). This procedure relies on
SIGILL to determine CPU capabilities. A.
