From: Cupertino Miranda Date: Tue, 7 Jun 2016 08:24:37 +0000 (+0200) Subject: Fixes to legacy ARC relocations. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a87aa054a67e23faeead400bdf902a1eddb242a4;p=binutils-gdb.git Fixes to legacy ARC relocations. Added support for ARC_SDA_12 reloc. Fixed ARC_N32_ME. Added ME (middle-endian) to ARC_SDA_12 reloc. bfd/ChangeLog: Cupertino Miranda * reloc.c: Fixed type in ARC_SECTOFF relocations. Added ARC_SDA_12 relocation. * bfd-in2.h: Regenerated from the previous changes. * libbfd.h: Regenerated from the previous changes. include/ChangeLog: Cupertino Miranda * elf/arc-reloc.def: Fixed relocation formula for N*, SDA, SDA_12, SDA_16_LD*, S13_PCREL, N32_ME, SECTOFF_* relocations. * opcode/arc-func.h (replace_disp12s): Added. Used for SDA_12 relocation. --- diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 5cb2fc17fa6..b7206aecac5 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,10 @@ +2016-08-26 Cupertino Miranda + + * reloc.c: Fixed type in ARC_SECTOFF relocations.
