2024-01-04Update year range in copyright notice of binutils filesAlan Modra1-1/+1
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.

Add new ARCv3 CPUs and required bits to decode/encode ARCv3 ISA opcodes. Fix 32 bit relocations which were set as signed but should be bitfield: ARC_32_ME, ARC_GLOB_DAT, ARC_JMP_SLOT, ARC_RELATIVE.

2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-1/+1
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.
2022-06-08HOWTO size encodingAlan Modra1-69/+69
This changes the HOWTO macro to encode the howto.size field from a value given in bytes.

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.

2016-04-20arc: Fix relocation formula for ARC_NPS_CMEM16 relocationAndrew Burgess1-1/+1
The ME modifier was missing from the relocation formula for the ARC_NPS_CMEM16 relocation, and as such the relocation would not patch correctly on little endian targets. include/ChangeLog: * elf/arc-reloc.def (ARC_NPS_CMEM16): Add ME modifier to formula.

Add support for arc/nps400 cmem instructions, these load and store instructions are hard-wired to access "0x57f00000 + 16-bit-offset".
