--- Comment #2 from pietro <pietro at sociotechnical dot xyz> --- (In reply to Andrew Pinski from comment #1) > I am 99% sure the problem is the definition of MAX_FIXED_MODE_SIZE. Yup, defining MAX_FIXED_MODE_SIZE to GET_MODE_BITSIZE (TImode) fixes the build. I'll send a patch when the testsuite finishes running. Thanks Andrew!
