New commands `enable probe' and `disable probe'.
This patch adds the above-mentioned commands to the generic probe
abstraction implemented in probe.[ch]. The effects associated to
enabling or disabling a probe depend on the type of probe being
handled, and is triggered by invoking two back-end hooks in
`probe_ops'.
In case some particular probe type does not support the notion of
enabling and/or disabling, the corresponding fields on `probe_ops' can
be initialized to NULL. This is the case of SystemTap probes.

Move `compute_probe_arg' and `compile_probe_arg' to probe.c
This patch moves the `compute_probe_arg' and `compile_probe_arg' functions
from stap-probe.c to probe.c. The rationale is that it is reasonable to
assume that all backends will provide the `$_probe_argN' convenience
variables, and that the user must be placed on the PC of the probe when
requesting that information. The value and type of the argument can still be
determined by the probe backend via the `pops->evaluate_probe_argument' and
`pops->compile_to_ax' handlers.
Note that a test in gdb.base/stap-probe.exp had to be adjusted because the "No
SystemTap probe at PC" messages are now "No probe at PC".

Adapt `info probes' to support printing probes of different types.
A "probe type" (backend for the probe abstraction implemented in
probe.[ch]) can extend the information printed by `info probes' by
defining additional columns. This means that when `info probes' is
used to print all the probes regardless of their types, some of the
columns will be "not applicable" to some of the probes (like, say, the
Semaphore column only makes sense for SystemTap probes). This patch
makes `info probes' fill these slots with "n/a" marks (currently it
breaks the table) and not include headers for which no actual probe
has been found in the list of defined probes.
This patch also adds support for a new generic column "Type", that
displays the type of each probe. SystemTap probes identify themselves
as "stap" probes.

Properly place the NULL STT_FILE symbol revistited
I was having a little closer look at what is going on here and noticed
that HJ unconditionally emits a NULL STT_FILE symbol before emitting
forced local symbols. That means we really don't need a second pass
over forced local symbols. The only reason for two passes is when
some forced local symbol can be emitted before the NULL STT_FILE. So
I set about removing the second pass, updating the testsuite all over
again. It's also unnecessary to emit the NULL STT_FILE when no
previous file symbol has been emitted.

TUI: resize windows to new terminal size before displaying them
If the user:
#1 - disables the TUI
#2 - resizes the terminal
#3 - and then re-enables the TUI
the next wgetch() returns KEY_RESIZE. This indicates to the ncurses
client that ncurses detected that the terminal has been resized. We
don't handle KEY_RESIZE anywhere, so it gets passed on to readline
which interprets it as a multibyte character, and then the end result
is that the first key press after enabling the TUI is misinterpreted.
We shouldn't really need to handle KEY_RESIZE (and not all ncurses
implementations have that). We have our own SIGWINCH handler, and,
when we re-enable the TUI, we explicitly detect terminal resizes and
resize all windows. The reason ncurses currently does detects a
resize is that something within tui_enable forces a refresh/display of
some window before we get to do the actual resizing. Setting a break
on ncurses' 'resizeterm' function helps find the culprit(s):

Fix --dynamic-list so that symbols not in the list are still exported.
In PR 13577, the complaint was that -Bsymbolic was overriding the binding
behavior for symbols listed in the --dynamic-list by setting the DT_SYMBOLIC
tag in the dynamic table. In reading the Gnu ld manual, I decided that
--dynamic-list should be mutually exclusive of -Bsymbolic, and modified
gold so that --dynamic-list would treat symbols listed as preemptible,
and all other symbols as internally bound. I was wrong.
PR 16992 shows that with --dynamic-list (and not -Bsymbolic), a symbol
not listed in the dynamic list is being internally bound within the
shared library, but because it's still in the dynamic symbol table, we
expose it to a COPY relocation, and things go really bad from there.
(I can reproduce the same failure, simply by turning on -Bsymbolic-functions
with the Gnu linker. Even though the symbol is bound internally, it's
still exported to the dynamic symbol table, and is exposed to a COPY
relocation.)
I've backed out part of the fix for PR 13577, and -Bsymbolic (or
-Bsymbolic-functions) can now be used with --dynamic-list, but if the
two are used together, we do not set DT_SYMBOLIC or DF_SYMBOLIC
(this matches Gnu ld behavior). We now treat symbols listed in the
dynamic list as premptible, but we do not automatically treat symbols
not listed there as non-premptible.

PR ld/17973 LTO file syms
LTO output objects have an STT_FILE symbol using the name of the file,
a temporary file. This results in executables that can't be exactly
reproduced, so the file name needs to be dropped. We don't want to
lose all file symbols when linking a mix of lto and non-lto objects as
a file symbol can be used to figure which source file generated a
given local symbol. So lto output objects need to be marked.
I chose to mark lto output objects with a new bfd flag. This flag is
also used to fix a bug in the link-once handling; An object being
loaded after "loading_lto_outputs" is set might be one extracted from
an archive to satisfy new references from lto objects, not an lto
object itself.
The new flag is copied from archive to elements, and the same done
for no_export. This fixes a bug in that --exclude-libs doesn't work
with thin archives. I'm not completely happy with this part of the

Fix redefinition errors in C++ mode
In C, we can forward declare static structure instances. That doesn't
work in C++ though. C++ treats these as definitions. So then the
compiler complains about symbol redefinition, like:
src/gdb/elfread.c:1569:29: error: redefinition of ‘const sym_fns elf_sym_fns_lazy_psyms’
src/gdb/elfread.c:53:29: error: ‘const sym_fns elf_sym_fns_lazy_psyms’ previously declared here
The intent of static here is naturally to avoid making these objects
visible outside the compilation unit. The equivalent in C++ would be
to instead define the objects in the anonymous namespace. But given
that it's desirable to leave the codebase compiling as both C and C++
for a while, this just makes the objects extern.
(base_breakpoint_ops is already declared in breakpoint.h, so we can
just remove the forward declare from breakpoint.c)

background single-step stops somewhere where PC-$decr_pc has a
breakpoint, and the thread that finishes the step is not the current
thread, like:
ADDR1 nop <-- breakpoint here
ADDR2 jmp PC
IOW, say thread A is stepping ADDR2's line in the background (an
infinite loop), and the user switches focus to thread B. GDB's
adjust_pc_after_break logic confuses the single-step stop of thread A
for a hit of the breakpoint at ADDR1, and thus adjusts thread A's PC
to point at ADDR1 when it should not, and reports a breakpoint hit,
when thread A did not execute the instruction at ADDR1 at all.
The test added by this patch exercises exactly that.
I can't find any reason we'd need the "thread to be examined is still
the current thread" condition in adjust_pc_after_break, at least
nowadays; it might have made sense in the past. Best just remove it,
and rely on currently_stepping().
Here's the test's log of a run with an unpatched GDB:

Fix a pair of screen-resizing issues in TUI
This patch fixes a pair of TUI issues related to screen resizing:
1. In tui_handle_resize_during_io(), when the TUI screen gets resized,
we fail to update GDB's idea about the height of the output window.
You can see this bug by doing:
a. Enter TUI mode.
b. "show height"
c. Resize the terminal.
d. "show height"
And observe that despite resizing the terminal, the reported height
remains unchanged. Note that a similar issue exists in the CLI.
The fix for this is simple: call tui_update_gdb_sizes() after performing
a resize, so that the "height" variable remains consistent with the
height of TUI's output window.
2. In tui_enable(), the call to tui_update_gdb_sizes() may clobber
readline's idea of the actual screen dimensions, and a subsequent
pending resize will use bogus terminal dimensions.
You can see this bug by doing:
a. Enter TUI mode.
b. Exit TUI mode.
c. Resize the terminal.
d. Enter TUI mode.
e. Press a key to resize the screen.
And observe that the terminal gets incorrectly resized to the wrong
dimensions. To fix this issue, we should oppurtunistically resize the
screen in tui_enable(). That way we eliminate the possibility of a
pending resize triggering right after we call tui_update_gdb_sizes().
gdb/ChangeLog:
* tui/tui-io.c (tui_handle_resize_during_io): Call
tui_update_gdb_sizes() after resizing the screen.
* tui/tui.c (tui_enable): Resize the terminal before
calling tui_update_gdb_sizes().

Fix truncation of TUI command history
If we submit a command while the prompt cursor is somewhere other than
at the end of the command line, the command line gets truncated as the
command window gets shifted one line up. This happens because we fail
to properly move the cursor to the end of the command line before
transmitting the newline to ncurses. We need to move the cursor because
when ncurses outputs a newline it truncates any text that appears
past the end of the cursor.
The fix is generic enough to work properly even in multi-line secondary
prompts like the quit prompt.

* tui/tui-io.c (tui_getc): Move cursor to the end of the command
line before printing a newline.

displaced_step_fixup may access memory from the wrong inferior/thread

btrace: identify cpu
Add a struct for identifying a processor and use it in linux-btrace.c when
identifying the processor we're running on.
We will need this feature for the new btrace format.
