-Subject: [PATCH 1/4] arc: Add support for signal handlers
-
-This patch adds the necessary infrastructure to handle signal frames for
-ARC architecture.  It is fairly similar to what any other architecture
-would have.  Linux specific parts will be in a separate patch.
-
-v2 [1]:
-- Make the logic of "arc_sigtramp_frame_sniffer ()" simpler.
-
-[1] Tom's remark for the first version
-https://sourceware.org/pipermail/gdb-patches/2020-November/173221.html
-
-gdb/ChangeLog:
-
-        * arc-tdep.c (arc_make_sigtramp_frame_cache): New function.
-        (arc_sigtramp_frame_this_id): Likewise.
-        (arc_sigtramp_frame_prev_register): Likewise.
-        (arc_sigtramp_frame_sniffer): Likewise.
-        (arc_siftramp_frame_unwind): New global variable.
-        (arc_gdbarch_init): Use sigtramp capabilities.
-        (arc_dump_tdep): Print sigtramp fields.
-        * arc-tdep.h (gdbarch_tdep): Add sigtramp fields.
-

-Subject: [PATCH 3/4] arc: Take into account the REGNUM in supply/collect gdb
- hooks
-
-All the arc_linux_supply_*() target operations and the
-arc_linux_collect_v2_regset() in arc-linux-tdep.c were
-supplying/collecting all the registers in regcache as if the
-REGNUM was set to -1.
-
-The more efficient behavior is to examine the REGNUM and act
-accordingly.  That is what this patch does.
-
-gdb/ChangeLog:
-
-        * arc-linux-tdep.c (supply_register): New.
-        (arc_linux_supply_gregset, arc_linux_supply_v2_regset,
-        arc_linux_collect_v2_regset): Consider REGNUM.

-Subject: [PATCH 4/4] gdb: Add native support for ARC in GNU/Linux
-
-With this patch in place it is possible to build a GDB that
-can run on ARC (GNU/Linux) hosts for debugging ARC targets.
-
-The "arc-linux-nat.c" is a rather small one that mostly deals
-with registers and a few thread related hooks.
-
-v2 [1]:
-- Remove "void" from the input of "_initialize_arc_linux_nat ()"
-
-[1] Tom's remark after the first patch
-https://sourceware.org/pipermail/gdb-patches/2020-November/173223.html
-
-gdb/ChangeLog:
-
-        * Makefile.in (ALLDEPFILES): Add arc-linux-nat.c.
-        * configure.host (host to gdb names): Add arc*-*-linux*.
-        * configure.nat (gdb_host_cpu): Add arc.
-        * arc-linux-nat.c: New.
