[PATCH v3 0/5] OpenRISC binutils updates and new relocs


Hello,

Changes since v2:
  - Fixed issue with reloc overflow detection (ld-scripts/pr22267)

Changes since v1:
  - Added documentation for GAS
  - Fixed format issues with enum '{' and 'function_(' space
  - Added messages before 'abort()'

This series contains a lot of updates for OpenRISC binutils.  Including:
  - Definitions for missing instructions.
  - New relocations used in the new GCC OpenRISC port
  - A new instruction l.adrp

The patches were for the most part written by Richard Henderson, I have fixed a
few bugs, added additional tests and wrote the ChangeLogs.

These patches have been tested and used in the new OpenRISC GCC clean-room
rewrite done by Richard and Me.
