libm-test-ulps regeneration is considered obvious.  (The libm-test.inc 
code now ensures that ulps don't get added for functions that should have 
exactly determined results, and that, if added, such ulps are ignored when 
libm-test-ulps is read.  So, given that code

#if TEST_COND_ldbl_128ibm
  /* The documented accuracy of IBM long double division is 3ulp (see
     libgcc/config/rs6000/ibm-ldouble-format), so do not require
     better accuracy for libm functions that are exactly defined for
     other formats.  */
  max_valid_error = exact ? 3 : 14;
#else
  max_valid_error = exact ? 0 : 9;
#endif

there's no real possibility of a bad libm-test-ulps update as long as you 
use "make regen-ulps" rather than trying to update it manually.)
