From 30ce8e47fad9b057b6d7af9e1d43061126d34d20 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Sun, 19 Apr 2020 19:04:41 -0700 Subject: xtensa: fix PR ld/25861 Introduce new relaxations XTENSA_PDIFF{8,16,32} for positive differences (subtracted symbol precedes diminished symbol) and XTENSA_NDIFF{8,16,32} for negative differences (subtracted symbol follows diminished symbol). Don't generate XTENSA_DIFF relocations in the assembler, generate XTENSA_PDIFF or XTENSA_NDIFF based on relative symbol position. Handle XTENSA_DIFF in BFD for compatibility with old object files. Handle XTENSA_PDIFF and XTENSA_NDIFF in BFD, treating difference value as unsigned. 2020-04-22 Max Filippov bfd/ * bfd-in2.h: Regenerated. * elf32-xtensa.c (elf_howto_table): New entries for R_XTENSA_PDIFF{8,16,32} and R_XTENSA_NDIFF{8,16,32}.
