This patch fixes a problem that problem triggers if you start an
inferior, e.g., with the "start" command, in a UI created with the
new-ui command, and then run a foreground execution command in the
main UI. Once the program stops for the latter command, typing in the
main UI no longer echoes back to the user.
The problem revolves around this:
- gdb_has_a_terminal computes its result lazily, on first call.
that is what saves gdb's initial main UI terminal state (the UI
associated with stdin):
our_terminal_info.ttystate = serial_get_tty_state (stdin_serial);
This is the state that target_terminal_ours() restores.
- In this scenario, the gdb_has_a_terminal function happens to be
first ever called from within the target_terminal_init call in
startup_inferior:
(top-gdb) bt
#0 gdb_has_a_terminal () at src/gdb/inflow.c:157
#1 0x000000000079db22 in child_terminal_init_with_pgrp () at src/gdb/inflow.c:217
[...]
#4 0x000000000065bacb in target_terminal_init () at src/gdb/target.c:456
#5 0x00000000004676d2 in startup_inferior () at src/gdb/fork-child.c:531
[...]
#7 0x000000000046b168 in linux_nat_create_inferior () at src/gdb/linux-nat.c:1112
[...]
#9 0x00000000005f20c9 in start_command (args=0x0, from_tty=1) at src/gdb/infcmd.c:657
If the command to start the inferior is issued on the main UI, then
readline will have deprepped the terminal when we reach the above, and
the problem doesn't appear.
If however the command is issued on a non-main UI, then when we reach
that gdb_has_a_terminal call, the main UI's terminal state is still
set to whatever readline has sets it to in rl_prep_terminal, which
happens to have echo disabled. Later, when the following synchronous
execution command finishes, we'll call target_terminal_ours to restore
gdb's the main UI's terminal settings, and that restores the terminal
state with echo disabled...
Conceptually, the fix is to move the gdb_has_a_terminal call earlier,
to someplace during GDB initialization, before readline/ncurses have
had a chance to change terminal settings. Turns out that
"set_initial_gdb_ttystate" is exactly such a place.
I say conceptually, because the fix actually inlines the
gdb_has_a_terminal part that saves the terminal state in
set_initial_gdb_ttystate and then simplifies gdb_has_a_terminal, since
there's no point in making gdb_has_a_terminal do lazy computation.

Hi,
I happen to see gdbserver is spawned like this in gdb.log,
spawn /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../../gdb/gdbserver/gdbserver --once :2346 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.s

erver/connect-stopped-target/connect-stopped-target /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.server/connect-stopped-target/connect-stopped-t
arget
as we can see, there are two instances of connect-stopped-target or
connect-stopped-target in the command line spawning gdbserver, but
none of these gets parameters from command line. In these two
tests, gdbserver is spawned via "gdbserver_spawn ${binfile}". However,
the argument of gdbserver_spawn is the argument passed the child
inferior, not the program itself.
# Start a gdbserver process running SERVER_EXEC, and connect GDB
# to it. CHILD_ARGS are passed to the inferior.
#
# Returns the target protocol and socket to connect to.
proc gdbserver_spawn { child_args } {
set target_exec [gdbserver_download_current_prog]
GDBserver gets the program via last_loaded_file, which is set by
gdb_file_cmd. In each test, we don't need to pass ${binfile}.

For consistency with the previous two patches, this one
adds a macro for the two ARMv8.2 table entries. Both table
entries need a non-null aarch64_op field.
I haven't added macros for the RAS and STAT_PROFILE entries
since there's only one of each. The series isn't getting
rid of braced entries altogether, so I've only looked at
replacing things that occur more than once.
opcodes/
* aarch64-tbl.h (V8_2_INSN): New macro.
(aarch64_opcode_table): Use it.
After the previous patch, this one makes all CORE, FP
and SIMD table entries with null "verify" fields use
the associated macros.
opcodes/
* aarch64-tbl.h (aarch64_opcode_table): Make more use of
CORE_INSN, __FP_INSN and SIMD_INSN.
Nick recently wrapped most of aarch64-tbl.h entries in macros
like CORE_INSN. These new macros assumed that the aarch64_op
"op" field of aarch64_opcode is 0 and that the new "verifier"
field is NULL.
However, there are a lot of CORE, SIMD and FP insns whose table
entries need a nonzero aarch64_op field, so these entries
continued to use a braced list instead of a macro. This makes
the table entries less consistent and means that there are still
quite a few braced entries that need to be updated when making
further changes to the aarch64_opcode structure.
I think the number of entries that need a nonzero aarch64_op
field is high enough to justify having an explicit aarch64_op
entry for all CORE, SIMD and FP entries. This patch adds
one and updates all existing uses of the macros. A following
patch makes more use of the macros.
I've followed existing practice by using 0 instead of OP_NIL
for empty aarch64_op fields. Empty fields are still the norm
and you need to know what the fields are when reading the table
anyway, so it was hard to justify an additional patch to replace
all 0 op fields with OP_NIL.
opcodes/
* aarch64-tbl.h (CORE_INSN, __FP_INSN, SIMD_INSN): Add OP parameter.
(aarch64_opcode_table): Update uses accordingly.
Loading a core dump that was either generated on a system running
pristine glibc master, or on a Fedora/RHEL system with LD_DEBUG=unused
set in the environment, solib-svr4.c:svr4_current_sos fails to filter
out the vDSO, resulting in:
(gdb) core-file corefile.core^M

...
The problem is that gdbarch_vsyscall_range does not support core
inferiors at all.
When live debugging, we're finding the vDSO's start address with
auxv/AT_SYSINFO_EHDR, and then we find the vDSO's size by look for the
corresponding mapping, by parsing /proc/PID/maps. When debugging a
core dump, we can also determine the starting address from
auxv/AT_SYSINFO_EHDR. However, we obviously can't read the core
mappings out of the host's /proc. But we can instead look for a
corresponding load segment in the core's bfd.

Nowadays, we only match pre-indexed STP in prologue. Due to the change
in gcc, https://gcc.gnu.org/ml/gcc-patches/2016-07/msg01933.html, it
may generate "STP with base register" in prologue, which GDB doesn't
handle. That is to say, previously GCC generates prologue like this,
sub sp, sp, #490
stp x29, x30, [sp, #-96]!
mov x29, sp
with the gcc patch above, GCC generates prologue like like this,
sub sp, sp, #4f0
stp x29, x30, [sp]
mov x29, sp

This test only collects the PC, and thus expects to only see one

the 64-bit ABI gdb only exposes 64-bit $pc/$rip (register 16 above),
on x32, GDB exposes 32-bit $eip as well, as a pseudo-register
(register 204 above). Thus, collecting $pc/$rip automatically always
collects $eip as well.

The test sets a fast tracepoint on a shared library. On x32, shared
libraries end up loaded somewhere in the upper 2GB of the 4GB address
space x32 has access to. When gdbserver needs to copy an instruction
to execute it in the jump pad, it asks gdb to relocate/adjust it, with
the qRelocInsn packet. gdb converts "call" instructions into a "push
$<2GB-4GB addr> + jmp" sequence, however, the "pushq" instruction sign
extends its operand, so later when the called function returns, it
returns to an incorrectly sign-extended address. E.g.,
0xfffffffffabc0000 instead of 0xfabc0000, resulting in the
segmentation fault.
Fix this by converting calls at such addresses to "sub + mov + jmp"
sequences instead.

Warning: Can not remove current symbol inferior 1.
gdb/ChangeLog:
* inferior.c (remove_inferior_command): Fix error message.
gdb/testsuite/ChangeLog:
* gdb.multi/remove-inferiors.exp (test_remove_inferiors): Fix
expected error message.
I noticed that the remove-inferiors command was not tested, and as I am
doing some changes related to the user selection, I want to make sure I
don't break it. For example, I want to make sure it's not possible to
remove the current inferior.
gdb/testsuite/ChangeLog:
* gdb.multi/remove-inferiors.exp: New file.
* gdb.multi/remove-inferiors.c: New file.
Build the test objects with the in-tree assembler. Also fix some cascading
error messages caused by not resetting the skip_call_tls_get_addr_ flag
after printing the error.

* i386.cc (Target_i386): Reset skip_call_tls_get_addr_ after printing
error message.
* testsuite/Makefile.am (pr20216a): Add missing dependencies.
(pr20308a): Add -Bgcctestdir/ to compile rules.
* testsuite/Makefile.in: Regenerate.
The common sim tracing code already handles loading and tracking of
symbols from the target program so that it can show symbol info in
trace/disassembly calls. Once we touch up the trace code and add a
few API callbacks, ports don't need to do loading and searching of
symbol tables themselves anymore.
