* arm-linux-tdep.c (arm_linux_copy_svc): Update debug message.
Hi,
I see this fail on arm-linux target,
FAIL: gdb.base/disp-step-syscall.exp: fork: single step over fork final pc
which is caused by the PC isn't expected after displaced stepping the
svc instruction. The code is:
=> 0xb6ead9a4 <__libc_do_syscall+4>: svc 0
0xb6ead9a6 <__libc_do_syscall+6>: pop {r7, pc}
0xb6ead9a8: nop.w^M
0xb6ead9ac: nop.w
after single step svc instruction, pc should be 0xb6ead9a6, but the
actual value of pc is 0xb6ead9a8. The problem is illustrated by
turning on debug message of displaced stepping,
stepi^M
displaced: stepping Thread 12031 now^M

displaced: writing pc b6ead9a8 <----- WRONG ADDRESS
GDB writes the wrong address back to pc because GDB thinks the
instruction size is 4, which isn't true for thumb instruction.
This patch is to replace 4 with dsc->insn_size.

* arm-linux-tdep.c (arm_linux_cleanup_svc): Use

I see many fails in gdb.dwarf2/dynarr-ptr.exp on arm-linux target,
started from this
print foo.three_ptr.all^M
Cannot access memory at address 0x107c8^M
(gdb) FAIL: gdb.dwarf2/dynarr-ptr.exp: print foo.three_ptr.all
print foo.three_ptr.all(1)^M
Cannot access memory at address 0x107c8
It turns out that ":$ptr_size" is used incorrectly.
array_ptr_label: DW_TAG_pointer_type {
{DW_AT_byte_size :$ptr_size }
^^^^^^^^^^
{DW_AT_type :$array_label}
}
Since the FORM isn't given, and it starts with the ":", it is regarded
as a label reference by dwarf assembler. The generated asm file on
x86_64 is
.uleb128 6 /* Abbrev (DW_TAG_pointer_type) */
.4byte 8 - .Lcu1_begin <----- WRONG
.4byte .Llabel2 - .Lcu1_begin
Looks .Lcu1_begin is 0 on x86_64 and that is why this test passes on
x86_64. On arm, .Lcu1_begin is an address somewhere, and the value
of DW_AT_byte_size is a very large number, so memory read request
of such large length failed.
This patch is to remove ":" and set the form explicitly. The generated
asm file on x86_64 becomes
.uleb128 6 /* Abbrev (DW_TAG_pointer_type) */
.byte 8
.4byte .Llabel2 - .Lcu1_begin

I see the following two timeout fails on pandaboard (arm-linux target),
FAIL: gdb.base/watch-bitfields.exp: -location watch against bitfields: continue until exit (timeout)
FAIL: gdb.base/watch-bitfields.exp: regular watch against bitfields: continue until exit (timeout)
In this test, more than one watchpoint is used, so the following
watchpoint requests fall back to software watchpoint, so that GDB
will single step all the way and it is very slow.
This patch is to copy the fix from
[PATCH] GDB/testsuite: Correct gdb.base/watchpoint-solib.exp timeout tweak
https://sourceware.org/ml/gdb-patches/2014-07/msg00716.html
I find the left-over of this patch review is to factor out code into
a procedure, so I do that in this patch.
Re-run tests watch-bitfields.exp, watchpoint-solib.exp, sigall-reverse.exp,
and until-precsave.exp on pandaboard, no regression.

Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the
cpu state is multicore, and the STATE_CPU defines match, we can move
it all to the common code.
This sets up the sim_state structure and the cpu member to match what we
do in most other sims, and what the common code suggests. This is a step
to unifying on the sim-cpu.o object.
This patch adds --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi]

Address of protected data defined in the shared library may be external,
i.e., due to copy relocation. By default, linker backend checks if
relocations against protected data symbols are valid for building shared
library and issues an error if relocation isn't allowed. The new option
override linker backend default. When -z noextern-protected-data is used,
updates on protected data symbols by another module won't be visibile
to the resulting shared library. This option is specific to ELF/i386

Recognize NT_X86_XSTATE notes in FreeBSD process cores. Recent
FreeBSD versions include a note containing the XSAVE state for each
thread in the process when XSAVE is in use. The note stores a copy of
the current XSAVE mask in a reserved section of the machine-defined
XSAVE state at the same offset as Linux's NT_X86_XSTATE note.
For native processes, use the PT_GETXSTATE_INFO ptrace request to
determine if XSAVE is enabled, and if so the active XSAVE state mask
(that is, the value of %xcr0 for the target process) as well as the
size of XSAVE state area. Use the PT_GETXSTATE and PT_SETXSTATE requests
to fetch and store the XSAVE state, respectively, in the BSD x86
native targets.
In addition, the FreeBSD amd64 and i386 native targets now include
"read_description" target methods to determine the correct x86 target
description for the current XSAVE mask. On FreeBSD amd64 this also
properly returns an i386 target description for 32-bit binaries which
allows the 64-bit GDB to run 32-bit binaries.
Note that the ptrace changes are in the BSD native targets, not the
FreeBSD-specific native targets since that is where the other ptrace
register accesses occur. Of the other BSDs, NetBSD and DragonFly use
XSAVE in the kernel but do not currently export the extended state via
ptrace(2). OpenBSD does not currently support XSAVE.

The following patch prevents a number of failures by detecting this and bailing out in case the target has such a restriction. Writing to .text from within the program isn't any better. It just leads to a SIGSEGV.

* gdb.base/bp-permanent.exp (test): Handle the case of being unable

This testcase seems to assume the target is running Linux, so bare metal,
simulators and other debugging stubs running different OS' will have a
hard time executing some of the commands the testcase issues.
Even restricting the testcase to Linux systems (which the patch below does),
there are still problems with, say, QEMU not providing PID information when
"info inferior" is issued. As a consequence, the subsequent tests will either
fail or will not make much sense.
The attached patch checks if PID information is available. If not, it just
bails out and avoids running into a number of failures.

In gdb-sigterm.exp, SIGTERM is sent to GDB and it exits. However,
Dejagnu or tcl doesn't know this.

Pedro Alves:
The commands that enables aren't even documented in the manual.
Judging from that, I assume that only wdb users would ever really
be using the --xdb switch.
I think it's time to drop "support" for the --xdb switch too. I
looked through the commands that that exposes, the only that looked
potentially interesting was "go", but then it's just an alias
for "tbreak+jump", which can easily be done with "define go...end".
I'd rather free up the "go" name for something potentially
more interesting (either run control, or maybe even unrelated,
e.g., for golang).
