New Revision: 321484
URL: https://svnweb.freebsd.org/changeset/base/321484

Log:
  Only test ld_pi_odd with LDBL_MANT_DIG == 64 to fix the build
  
  The empty (unimplemented) test inputs for sparc64 trigger a -Wtype-limits build
  failure because nitems of an empty array is always false, i.e., deadcode.
