[Bug optimization/14541] New: [tree-ssa] gcc.dg/torture/builtin-explog-1.c fails

[kazu at cs dot umass dot edu]

Here is a reduced testcase.
Basically, link_error won't go away.
This testcase works on mainline, so this is a regression.

extern double log (double);
extern double exp (double);
extern void link_failure (void);

void
test (double d1)
{
  if (log (exp (d1)) != d1)
    link_failure ();
}

int
main (void)
{
  return 0;
}
