-+/* Recognizing signal handler frames.  */
-+
-+/* GNU/Linux has two flavors of signals.  Normal signal handlers, and
-+   "realtime" (RT) signals.  The RT signals can provide additional
-+   information to the signal handler if the SA_SIGINFO flag is set
-+   when establishing a signal handler using `sigaction'.  It is not
-+   unlikely that future versions of GNU/Linux will support SA_SIGINFO
-+   for normal signals too.  */
-+
-+/* When the SH Linux kernel calls a signal handler and the
-+   SA_RESTORER flag isn't set, the return address points to a bit of
-+   code on the stack.  This function returns whether the PC appears to
-+   be within this bit of code.
-+
-+   The instruction sequence for normal signals is
-+       mov.w  1f,r3
-+       trapa  #16
-+       or     r0, r0
-+       or     r0, r0
-+       or     r0, r0
-+       or     r0, r0
-+       or     r0, r0
-+    1: .word  __NR_sigreturn
-+   or 0x9305 0xc310 0x200b 0x200b 0x200b 0x200b 0x200b 0x0077.
-+
-+   Checking for the code sequence should be somewhat reliable, because
-+   the effect is to call the system call sigreturn.  This is unlikely
-+   to occur anywhere other than a signal trampoline.
-+
-+   It kind of sucks that we have to read memory from the process in
-+   order to identify a signal trampoline, but there doesn't seem to be
-+   any other way.  The PC_IN_SIGTRAMP macro in tm-linux.h arranges to
-+   only call us if no function name could be identified, which should
-+   be the case since the code is on the stack.
-+
-+   Detection of signal trampolines for handlers that set the
-+   SA_RESTORER flag is in general not possible.  Unfortunately this is
-+   what the GNU C Library has been doing for quite some time now.
-+   However, as of version 2.1.2, the GNU C Library uses signal
-+   trampolines (named __restore and __restore_rt) that are identical
-+   to the ones used by the kernel.  Therefore, these trampolines are
-+   supported too.  */

+Subject: [PATCH] [AArch64] Make gdbserver register set selection dynamic
+
+The current register set selection mechanism for AArch64 is static, based
+on a pre-populated array of register sets.
+
+This means that we might potentially probe register sets that are not
+available. This is OK if the kernel errors out during ptrace, but probing the
+tag_ctl register, for example, does not result in a ptrace error if the kernel
+supports the tagged address ABI but not MTE (PR 28355).
+
+Making the register set selection dynamic, based on feature checks, solves
+this and simplifies the code a bit. It allows us to list all of the register
+sets only once, and pick and choose based on HWCAP/HWCAP2 or other properties.
+

-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.
-
-Upstream-Status: Backport [https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=b4e3cd0440109d0a5552d3313ccbd35c8103335b]

-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.
