From b33e8514836a6724b54d50f1cc42fea9ffc923b0 Mon Sep 17 00:00:00 2001 From: Andreas Schwab Date: Wed, 5 Jan 2005 22:51:47 +0000 Subject: * ia64-tdep.c: Include "osabi.h". (native_find_global_pointer): Delete. (ia64_find_global_pointer): Renamed from generic_elf_find_global_pointer. (FIND_GLOBAL_POINTER): Delete. Change all users to call ia64_find_global_pointer instead. (ia64_gdbarch_init): Call gdbarch_init_osabi. Remove references to ia64_linux_sigcontext_register_address and ia64_linux_write_pc. Don't set tdep->find_global_pointer. (_initialize_ia64_tdep): Call gdbarch_register instead of deprecated register_gdbarch_init. (struct gdbarch_tdep): Remove find_global_pointer field and move to ... * ia64-tdep.h (struct gdbarch_tdep): ... here. (ia64_linux_sigcontext_register_address): Remove declaration. (ia64_linux_getunwind_table): Likewise. (ia64_linux_write_pc): Likewise. * ia64-linux-tdep.c: Include "osabi.h". (ia64_linux_sigcontext_register_address): Make static. (ia64_linux_write_pc): Likewise. (ia64_linux_init_abi): New.
