From 50d10658eef31d1c68763d556f02954b9c7c4f00 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Thu, 12 Jan 2012 14:03:12 +0000 Subject: [PATCH] add indirect_symbol to mach-o port. bfd: * mach-o.c (bfd_mach_o_count_indirect_symbols): New. (bfd_mach_o_build_dysymtab_command): Populate indirect symbol table. * mach-o.h (bfd_mach_o_asymbol): Move declaration to start of the file. (bfd_mach_o_section): Add indirect_syms field. gas: * config/obj-macho.c (obj_mach_o_set_symbol_qualifier): Switch off lazy when the symbol is private_extern. (obj_mach_o_indirect_sym): New type. (obj_mach_o_indirect_symbol): New. (mach_o_pseudo_table): Use obj_mach_o_indirect_symbol. (obj_macho_frob_label): Adjust to avoid adding bsyms for locals. (obj_macho_frob_label): Likewise. Adjust external and comm symbol tests. (obj_mach_o_set_indirect_symbols): New. (obj_mach_o_frob_file_after_relocs): New. *config/obj-macho.h (obj_frob_file_after_relocs): Define.
