From: Andreas Arnez Date: Tue, 2 Sep 2014 14:00:44 +0000 (+0000) Subject: NIOS2: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections' X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c5b8d704bc8cf2fa2c6f23cbdb57c935550e6a6a;p=binutils-gdb.git 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.
