Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- So, IMHO either get_mode_bounds needs to special case BImode like trunc_int_for_mode does and make the bounds of BImode include values of 0 and STORE_FLAG_VALUE, or the BImode hunk in trunc_int_for_mode needs to be dropped and everything analyzed for assumption that BImode true is CONST_INT equal to STORE_FLAG_VALUE, or ia64 needs to use STORE_FLAG_VALUE -1 (there is a comment about it in ia64.h that it should be investigated).
