Use frag symbols with a non-zero offset directly in `fix_new_exp' calls made in PIC branch relaxation. There is no need here to make a helper symbol to hold the result of a `symbol+offset' calculation requested as only branches to local symbols are relaxed and in this case the LO16 part of the PIC address load sequence will have the offset accounted for in calculation against the local GOT entry retrieved as the GOT16 high part. Consequently actual code produed is identical whether a helper symbol is used or the original `symbol+offset' expression used directly. Verify that this is indeed the case with GAS and LD tests. gas/ * config/tc-mips.c (md_convert_frag): Don't make a helper expression symbol for `fix_new_exp' called with a non-zero offset. * testsuite/gas/mips/relax-offset.d: New test. * testsuite/gas/mips/mips1@relax-offset.d: New test. * testsuite/gas/mips/r3000@relax-offset.d: New test. * testsuite/gas/mips/r3900@relax-offset.d: New test. * testsuite/gas/mips/micromips@relax-offset.d: New test. * testsuite/gas/mips/relax-offset.l: New stderr output. * testsuite/gas/mips/relax-offset.s: New test source. * testsuite/gas/mips/mips.exp: Run the new tests. ld/ * testsuite/ld-mips-elf/relax-offset.dd: New test. * testsuite/ld-mips-elf/relax-offset.gd: New test. * testsuite/ld-mips-elf/relax-offset-umips.dd: New test. * testsuite/ld-mips-elf/relax-offset-umips.gd: New test. * testsuite/ld-mips-elf/relax-offset.ld: New test linker script. * testsuite/ld-mips-elf/mips-elf.exp: Run the new tests.
