Fields marked with XTENSA_NDIFF relocations are not negated, they only have sign bits removed. Don't negate their values when relaxation is performed. Don't add sign bits when the value is zero. Report overflow when the result has negative sign but all significant bits are zero. 2020-04-29 Max Filippov <jcmvbkbc@gmail.com> bfd/ * elf32-xtensa.c (relax_section): Don't negate diff_value for XTENSA_NDIFF relocations.
