bfd/ 2016-03-08 Cupertino Miranda <Cupertino.Miranda@synopsys.com> Andrew Burgess <andrew.burgess@embecosm.com> * elf32-arc.c (arc_bfd_get_32): Becomes an alias for bfd_get_32. (arc_bfd_put_32): Becomes an alias for bfd_put_32. (arc_elf_howto_init): Added assert to validate relocations. (get_middle_endian_relocation): Delete. (middle_endian_convert): New function. (ME): Redefine, now does nothing. (IS_ME): New define. (arc_do_relocation): Extend the attached 'ARC_RELOC_HOWTO' definition to call middle_endian_convert. Add a new local variable and make use of this throughout. Added call to arc_bfd_get_8 and arc_bfd_put_8 for 8 bit relocations. gas/ 2016-03-08 Andrew Burgess <andrew.burgess@embecosm.com> * testsuite/gas/arc/inline-data-1.d: New file. * testsuite/gas/arc/inline-data-1.s: New file. include/ 2016-03-08 Cupertino Miranda <Cupertino.Miranda@synopsys.com> Andrew Burgess <andrew.burgess@embecosm.com> * elf/arc-reloc.def: Add a call to ME within the formula for each relocation that requires middle-endian correction.
