--- Comment #12 from Eric Botcazou <ebotcazou at gcc dot gnu.org> 2011-07-09 10:27:42 UTC --- Since the PR was opened, a new usage of MAX_FIXED_MODE_SIZE has been introduced: 2006-11-18 John David Anglin <dave.ang...@nrc-cnrc.gc.ca> PR fortran/27885 PR middle-end/28176 * stor-layout.c (set_sizetype): Limit precision of *bitsizetypes types to MAX_FIXED_MODE_SIZE. so bumping MAX_FIXED_MODE_SIZE to 128 will also bump the size of these types. That's very likely OK anyway. FWIW I'm evaluating the change for SPARC64.
