GDB in default prints the symbol associated on an address, and tests
assume that there is no symbol on address zero. However, on bare
metal target, address may be mapped to zero and there may be a
symbol. Then, some tests fail as below:
print const_cast<void *> (0)^M
$8 = (void *) 0x0 <_ftext>^M
(gdb) FAIL: gdb.cp/casts.exp: const_cast of 0
p acp->c1^M
$9 = (A *) 0x0 <_ftext>^M
(gdb) FAIL: gdb.cp/class2.exp: p acp->c1

Hi,
Parameter 'pst' of function dwarf_decode_lines_1 isn't used except
to compute decode_for_pst_p, which has been got in the caller
dwarf_decode_lines. I wonder it would be good if we just pass
'decode_for_pst_p'.

* dwarf2read.c (dwarf_decode_lines_1): Remove parameter 'pst'.
Add parameter 'decode_for_pst_p'. Callers update.
These multiple if statements can be condensed down into a single if
statement and an array of strings.

This also makes --enable-plugins default to on for hosts that can
support plugins, so we have consistent lto toolchain support. The
ACX_LARGEFILE moves aren't strictly necessary, but are harmless and
will be necessary if plugin support is extended to more hosts via
libtool's dlopen support. I started down that path then decided it
was more work than I was interested in doing. (ACX_LARGEFILE invokes
AC_PLUGINS.)

The variables used to track insn state should be pushed down into the
private_data structure to avoid pollution across calls.
This also happens to fix the output when hitting comments/invalid insns
which needs to tweak a gas test.

If the user gives us an unaligned PC, then dump an error as such.
Otherwise if you try to disassemble at an odd address, the output
will look weird (it'll read one byte earlier).
This can be seen in one of the gas tests where data is in the middle
of .text, so move the data to .data like it should be in the first place.

The current code ignores memory read errors which isn't a great idea.
So add a helper function which takes care of error checking and update

This patch is to fix the build error when GDB is configured as:
CFLAGS=-Wall ./configure --with-babeltrace; make
This patch adds one line of code in configure test to use local
variable 'pos'.
Note that we append -Werror to CFLAGS to catch the warning related to
assignment to scope. See more in this thread

The main aim of this change was to have non_ir_ref set correctly on
new indirect symbols. I could have added a "copy" param to the "notice"
function, so that indirect symbols could be created in plugin_notice,
but it seemed cleaner to create indirect syms earlier and pass them
rather than "string" to "notice".

The code becomes dead as GDB evolves. In 2003, Andrew Cagney post patch
https://sourceware.org/ml/gdb-patches/2003-10/msg00511.html to add target
read/write partial methods. They support query buffer size when both
OFFSET and LEN is zero, and it was used in avr-tdep.c and kod.c. Then,
Daniel added target_read_object_alloc and avr-tdep.c switches to use that
in patch https://sourceware.org/ml/gdb-patches/2006-07/msg00009.html
From then on, GDB on longer queries the buffer size, so the code
returning packet size in remote_xfer_partial became dead.
PR 17060 is duplicated of PR 9053, so I mention the latter in the
ChangeLog entry. Rebuild GDB with this patch. OK to apply?
I'll mark PR 17060 as duplicated once the patch is applied.

I find some gdb.python tests fail on arm-none-eabi target, because the
tests assume that memory on address 0x is inaccessible. Some tests
(in gdb.base) are aware of this, so do a "x 0" check first. However,
the code is copy-n-paste.
This patch is to move the "x 0" check to a procedure in lib/gdb.exp,
and get needed tests call it. The original code matches pattern
"0x0:\[ \t\]*Error accessing memory address 0x0\r\n$gdb_prompt $", but
I remove it from the new proc is_address_zero_readable, because GDB
doesn't emit such message any more.
