cc463201c4
With the implemenations in this patch, ARC gdb can handle coredump related matters. The binutils counter part of this patch has already been pushed [1]. v2 [2]: - arc_linux_collect_gregset: Use "reg <= ARC_LAST_REGNUM" instead of "reg < ARC_LAST_REGNUM" for the condition check of the for-loop. - arc-linux-tdep.c: Use "ARC_LAST_REGNUM < ARRAY_SIZE (...)" instead of "ARC_LAST_REGNUM <= ARRAY_SIZE (...)" for the "asserts". - Use "buf + arc_linux_core_reg_offsets[ARC_ERET_REGNUM]" instead of "buf + REG_OFF (6)". - Fix a few typos/indentation. v3 [3]: - Use gdb_assert_not_reached(text) instead of gdb_assert (!text). - Remove unnecessary braces in the for loop. [1] arc: Add support for ARC HS extra registers in core files https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=2745674244d6aecddcf636475034bdb9c0a6b4a0 [2] First remarks https://sourceware.org/pipermail/gdb-patches/2020-September/171912.html [3] Second remarks https://sourceware.org/pipermail/gdb-patches/2020-October/172302.html gdb/ChangeLog: * arc-linux-tdep.h: New file. * arc-linux-tdep.c (arc_linux_core_reg_offsets, arc_linux_supply_gregset, arc_linux_supply_v2_regset, arc_linux_collect_gregset, arc_linux_collect_v2_regset, arc_linux_gregset, arc_linux_v2_regset, arc_linux_iterate_over_regset_sections, arc_linux_core_read_description): Implement. (arc_linux_init_osabi): Set iterate_over_regset_sections. * arc-tdep.h (ARC_OFFSET_NO_REGISTER): Declare. (arc_gdbarch_features_create): Add. * arc-tdep.c (arc_gdbarch_features_create): Not static anymore.
