Hi Ian, This is the patch for bug 13362. ARM EABI says that 32-bit static data relocations have alignment of 1. Previously, we incorrectly assume word alignment in a relocatable link. This patch adds a new strategy for unaligned 32-bit data relocations, which may be useful for other targets. I would have added unaligned 16-bit & 64-bit data relocations but ARM does not use these and I could not have tested them. The patch was tested for both ARM & x86_64. -Doug 2011-11-09 Doug Kwan <dougkwan@google.com> PR gold/13362 * arm.cc (Arm_scan_relocatable_relocs::Default_scan_relocatable_relocs): Use unaligned 4-byte relocs for static 32-bit data as required by EABI. * reloc.h (Relocatable_relocs::Reloc_strategy): New enum RELOC_ADJUST_FOR_SECTION_4_UNALIGNED.
