Subject: [PATCH]         * config/tc-tic80.c (build_insn): Handle instructions
 that have         long (32 bit) PC relative offsets.  Fix places that
 previously         misused R_MPPCR for 15 bit offsets to use the new
 R_MPPCR15W type.         (md_apply_fix): Add case to handle long PC relative
 offsets. PR 12927
