From c5b8d704bc8cf2fa2c6f23cbdb57c935550e6a6a Mon Sep 17 00:00:00 2001 From: Andreas Arnez Date: Tue, 2 Sep 2014 14:00:44 +0000 Subject: [PATCH] NIOS2: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections' For Nios II GNU/Linux targets, no longer define the gdbarch method 'regset_from_core_section', but the iterator method instead. gdb/ChangeLog: * nios2-linux-tdep.c (NIOS2_GREGS_SIZE): New macro. (nios2_regset_from_core_section): Remove. (nios2_iterate_over_regset_sections): New. (nios2_linux_init_abi): Adjust gdbarch initialization. --- gdb/ChangeLog | 7 +++++++ gdb/nios2-linux-tdep.c | 24 ++++++++++++++---------- 2 files changed, 21 insertions(+), 10 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 8bd3276..1610613 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,12 @@ 2014-09-30 Andreas Arnez + * nios2-linux-tdep.c (NIOS2_GREGS_SIZE): New macro. + (nios2_regset_from_core_section): Remove. + (nios2_iterate_over_regset_sections): New. + (nios2_linux_init_abi): Adjust gdbarch initialization. + +2014-09-30 Andreas Arnez + * mn10300-linux-tdep.c (am33_regset_from_core_section): Remove.
