From 490496c342237f3fa2dd92adfe9e34516991f451 Mon Sep 17 00:00:00 2001 From: Andreas Arnez Date: Sat, 29 Mar 2014 10:04:26 +0000 Subject: [PATCH] X86: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections' For all I386 and AMD64 targets, replace all occurrences of regset_from_core_section by the iterator method. gdb/ChangeLog: * amd64obsd-tdep.c (amd64obsd_regset_from_core_section): Remove. (amd64obsd_iterate_over_regset_sections): New. (amd64obsd_core_init_abi): Adjust gdbarch initialization. * i386-cygwin-tdep.c (i386_windows_regset_from_core_section): Remove. (i386_cygwin_init_abi): Clear tdep->sizeof_fpregset. Drop regset_from_core_section initialization. * i386-tdep.c (i386_regset_from_core_section): Remove. (i386_iterate_over_regset_sections): New. (i386_gdbarch_init): Adjust gdbarch initialization. * i386-tdep.h (i386_regset_from_core_section): Remove prototype.
