            Bug ID: 27780
           Summary: not report warning when set a breakpoint at invalid
                    address for arm64
           Product: gdb
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: wenyan.xin at windriver dot com
  Target Milestone: ---

we are developing a Gdb Server on VxWorks for arm64.

on gdb client side, I used the following command and got output.

(gdb) b *0
Breakpoint 2 at 0x0
(gdb) c
Continuing.
[Inferior 1 (process 1) exited normally]
(gdb)


Since the 0 address breakpoint is invalid, so the output should be as
following:

(gdb) b *0
Breakpoint 2 at 0x0
(gdb) c
Continuing.
Warning:
Cannot insert breakpoint 2.
Cannot access memory at address 0x0

Command aborted.

--=20
