* copy-relocs.h: New file. * reloc.cc: Remove Copy_relocs code. * reloc.h: Likewise. * reloc-types.h (struct Reloc_types) [both versions]: Add get_reloc_addend_noerror. * output.h (class Output_data_reloc<elfcpp::SHT_REL>): Add variants of add_global which take an addend which must be zero. * i386.cc: Include "copy-relocs.h". (class Target_i386): Change type of copy_relocs_ to variable, update initializer. (Target_i386::copy_reloc): Rewrite to pass to Copy_relocs class. Change all callers. (Target_i386::do_finalize_sections): Change handling of copy_relocs_. * sparc.cc: Include "copy-relocs.h". (class Target_sparc): Change type of copy_relocs_ to variable, update initializer. (Target_sparc::copy_reloc): Rewrite to pass to Copy_relocs class. Change all callers. (Target_sparc::do_finalize_sections): Change handling of copy_relocs_. * x86_64.cc: Include "copy-relocs.h". (class Target_x86_64): Change type of copy_relocs_ to variable, update initializer. (Target_x86_64::copy_reloc): Rewrite to pass to Copy_relocs class. Change all callers. (Target_x86_64::do_finalize_sections): Change handling of copy_relocs_. * Makefile.am (CCFILES): Add copy-relocs.cc. (HFILES): Add copy-relocs.h.
