            Bug ID: 30506
           Summary: [gdb/tdep, aarch64] FAIL:
                    gdb.dwarf2/dw2-prologue-end-2.exp: $break_addr ==
                    $foo_label_addr
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tdep
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

On openSUSE Leap 15.4 aarch64 I run into:
...
(gdb) break foo^M
Breakpoint 1 at 0x4005f8: file
/home/tdevries/gdb/src/gdb/testsuite/gdb.dwarf2/dw2-prologue-end-2.c, line
26.^M
(gdb) PASS: gdb.dwarf2/dw2-prologue-end-2.exp: break foo
print /x &foo_label^M
$1 = 0x4005f0^M
(gdb) PASS: gdb.dwarf2/dw2-prologue-end-2.exp: print /x &foo_label
print &foo_end == &bar_label^M
$2 = 1^M
(gdb) PASS: gdb.dwarf2/dw2-prologue-end-2.exp: print &foo_end == &bar_label
FAIL: gdb.dwarf2/dw2-prologue-end-2.exp: $break_addr == $foo_label_addr
...

This was noted here (
https://sourceware.org/pipermail/gdb-patches/2023-April/199053.html ).

This WIP ( https://sourceware.org/pipermail/gdb-patches/2023-April/199056.html
) fixes the FAIL on aarch64.

Also on arm, as mentioned here (
https://sourceware.org/pipermail/gdb-patches/2023-May/199614.html ).

commit 22f2cf64f178fa3c85508d08fe10dd4e98af4751
Author: Tom de Vries <tdevries@suse.de>
Date:   Tue May 16 17:00:51 2023 +0100

    Fix PR30369 regression on aarch64/arm (PR30506)

    The gdb.dwarf2/dw2-prologue-end-2.exp test was failing for both AArch64 and
    Arm.

    As Tom pointed out here
(https://inbox.sourceware.org/gdb-patches/6663707c-4297-c2f2-a0bd-f3e84fc62aad@suse.de/),
    there are issues with both the prologue skipper for AArch64 and Arm and an
    incorrect assumption by the testcase.

    This patch fixes both of AArch64's and Arm's prologue skippers to not skip
past
    the end of a function.  It also incorporates a fix to the testcase so it
    doesn't assume the prologue skipper will stop at the first instruction of
the
    functions/labels.

    Regression-tested on aarch64-linux/arm-linux Ubuntu 20.04/22.04 and
    x86_64-linux Ubuntu 20.04.
