--- Comment #6 from Dominik Vogt <vogt at linux dot vnet.ibm.com> --- (In reply to Jakub Jelinek from comment #5) > Looking around, I see various spots that need cleanup: > sizeof (HOST_WIDE_INT) * BITS_PER_UNIT should be IMHO HOST_BITS_PER_WIDE_INT > 1ULL in unsigned HOST_WIDE_INT contexts HOST_WIDE_INT_1U, 0ULL > HOST_WIDE_INT_0U. All right, I'll add that to the RISBG patches for gcc-8.0 and leave it in gcc-7.0 as it is now.
