--- Comment #8 from mrs at gcc dot gnu.org <mrs at gcc dot gnu.org> --- Author: mrs Date: Fri Nov 6 20:16:06 2015 New Revision: 229885 URL: https://gcc.gnu.org/viewcvs?rev=229885&root=gcc&view=rev Log: PR debug/66728 * dwarf2out.c (get_full_len): Return a value based upon the actual precision needed for the value. (add_const_value_attribute): Use a maximal wide-int for CONST_WIDE_INTs, not VOIDmode. (output_die): Don't ever output NULL with printf. * rtl.h (get_precision of rtx_mode_t): Ensure we never process BLKmode nor VOIDmode values. Modified: trunk/gcc/ChangeLog trunk/gcc/dwarf2out.c trunk/gcc/rtl.h
