Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.
2023-10-20bfd: microblaze: Add 32_NONE reloc typeNeal Frager1-0/+1
This patch adds the R_MICROBLAZE_32_NONE relocation type. This is a 32-bit reloc that stores the 32-bit pc relative value in two words (with an imm instruction). Add test case to gas test suite. Signed-off-by: Neal Frager <neal.frager@amd.com> Signed-off-by: Michael J. Eager <eager@eagercon.com>

2023-10-06opcodes: microblaze: Add new bit-field instructionsNeal Frager1-0/+1
This patches adds new bsefi and bsifi instructions. BSEFI- The instruction shall extract a bit field from a register and place it right-adjusted in the destination register. The other bits in the destination register shall be set to zero. BSIFI- The instruction shall insert a right-adjusted bit field from a register at another position in the destination register. The rest of the bits in the destination register shall be unchanged. Further documentation of these instructions can be found here: https://docs.xilinx.com/v/u/en-US/ug984-vivado-microblaze-ref This patch has been tested for years of AMD Xilinx Yocto releases as part of the following patch set: https://github.com/Xilinx/meta-xilinx/tree/master/meta-microblaze/recipes-devtools/binutils/binutils Signed-off-by: nagaraju <nagaraju.mekala@amd.com> Signed-off-by: Ibai Erkiaga <ibai.erkiaga-elorza@amd.com> Signed-off-by: Neal Frager <neal.frager@amd.com> Signed-off-by: Michael J.

The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.

2018-04-17[MicroBlaze] PIC data text relativeMichael Eager1-1/+3
Andrew Sadek <andrew.sadek.se@gmail.com> A new implemented feature in GCC Microblaze that allows Position Independent Code to run using Data Text Relative addressing instead of using Global Offset Table. Its aim was to make 'PIC' more efficient and flexible as elf size excess performance overhead were noticed when using GOT due to the indirect addressing. include/ChangeLog: * bfdlink.h (Add flag): Add new flag @ 'bfd_link_info' struct. * elf/microblaze.h (Add 3 new relocations): R_MICROBLAZE_TEXTPCREL_64, R_MICROBLAZE_TEXTREL_64 and R_MICROBLAZE_TEXTREL_32_LO for relax function. bfd/ChangeLog: * bfd/reloc.c (2 new BFD relocations): BFD_RELOC_MICROBLAZE_64_TEXTPCREL & BFD_RELOC_MICROBLAZE_64_TEXTPCREL * bfd/bfd-in2.h: Regenerate * bfd/libbfd.h: Regenerate * bfd/elf32-microblaze.c (Handle new relocs): define 'HOWTO' of 3 new relocs and handle them in both relocate and relax functions. (microblaze_elf_reloc_type_lookup): add mapping between for new bfd relocs. (microblaze_elf_relocate_section): Handle new relocs in case of elf relocation. (microblaze_elf_relax_section): Handle new relocs for elf relaxation. gas/ChangeLog: * gas/config/tc-microblaze.c (Handle new relocs directives in assembler): Handle new relocs from compiler output. (imm_types): add new imm types for data text relative addressing TEXT_OFFSET, TEXT_PC_OFFSET (md_convert_frag): conversion for BFD_RELOC_MICROBLAZE_64_TEXTPCREL, BFD_RELOC_MICROBLAZE_64_TEXTPCREL (md_apply_fix): apply fix for BFD_RELOC_MICROBLAZE_64_TEXTPCREL, BFD_RELOC_MICROBLAZE_64_TEXTPCREL (md_estimate_size_before_relax): estimate size for BFD_RELOC_MICROBLAZE_64_TEXTPCREL, BFD_RELOC_MICROBLAZE_64_TEXTPCREL (tc_gen_reloc): generate relocations for BFD_RELOC_MICROBLAZE_64_TEXTPCREL, BFD_RELOC_MICROBLAZE_64_TEXTPCREL ld/ChangeLog: * ld/lexsup.c (Add 2 ld options): (ld_options): add disable-multiple-abs-defs @ 'ld_options' array (parse_args): parse new option and pass flag to 'link_info' struct. * ld/ldlex.h (Add enum): add new enum @ 'option_values' enum. * ld/ld.texinfo (Add new option): Add description for 'disable-multiple-abs-defs' * ld/main.c: Initialize flags with false @ 'main'. Handle disable-multiple-abs-defs @ 'mutiple_definition'.
