FT32B is a new FT32 family member. It has a code compression scheme, which requires the use of linker relaxations. The change is quite large, so submission is in several parts. Part 1 adds a 15-bit instruction field, and CPU-specific functions for the code compression that are used in binutils and GDB. bfd/ChangeLog: 2017-10-12 James Bowman <james.bowman@ftdichip.com> * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * elf32-ft32.c: Add HOWTO R_FT32_15. * reloc.c: Add BFD_RELOC_FT32_15. gas/ChangeLog: 2017-10-12 James Bowman <james.bowman@ftdichip.com> * config/tc-ft32.c (md_assemble): Replace FT32_FLD_K8 with K15.
