This include is needed to access the definition of "struct iovec".

* amd64-linux-nat.c: Add <sys/uio.h> #include.

This commit renames nine files that contain code used by both 32- and
64-bit Intel ports such that their names are prefixed with "x86"
rather than "i386". All types, functions and variables within these
files are likewise renamed such that their names are prefixed with
"x86" rather than "i386". This makes GDB follow the convention used
by gdbserver such that 32-bit Intel code lives in files called
"i386-*", 64-bit Intel code lives in files called "amd64-*", and code
for both 32- and 64-bit Intel lives in files called "x86-*".
This commit only renames OS-independent files. The Linux ports of
both GDB and gdbserver now follow the i386/amd64/x86 convention fully.
Some ports still use the old convention where "i386" in file/function/
type/variable names can mean "32-bit only" or "32- and 64-bit" but I
don't want to touch ports I can't fully test except where absolutely
necessary.

This commit tidies up the #include lists in {i386,amd64}-linux-nat.c,
removing headers that are no longer required and reordering some lines
so that both files roughly match. Additionally, an unused definition
was removed from the middle of the #include list in i386-linux-nat.c.

amd64-linux-nat.c and i386-linux-nat.c contain a number of functions
which are identical but for prefix on their names. This commit
renames all such functions to have the prefix x86_ instead of the
prefixes amd64_ or i386_ and updates all uses of those functions.
The now-identical x86_ functions will be pulled out to a separate
shared file in a later commit.

This patch fixes this on x86 Linux:
(gdb) watch *buf@2
Hardware watchpoint 8: *buf@2
(gdb) si
0x00000000004005a7 34 for (i = 0; i < 100000; i++); /* stepi line */
(gdb) del
Delete all breakpoints? (y or n) y
(gdb) watch *(buf+1)@1
Hardware watchpoint 9: *(buf+1)@1
(gdb) si
0x00000000004005a7 in main () at ../../../src/gdb/testsuite/gdb.base/watchpoint-reuse-slot.c:34
34 for (i = 0; i < 100000; i++); /* stepi line */
Couldn't write debug register: Invalid argument.
(gdb)
In the example above the debug registers are being switched from this
state:
CONTROL (DR7): 0000000000050101 STATUS (DR6): 0000000000000000
DR0: addr=0x0000000000601040, ref.count=1 DR1: addr=0x0000000000000000, ref.count=0
DR2: addr=0x0000000000000000, ref.count=0 DR3: addr=0x0000000000000000, ref.count=0
to this:
CONTROL (DR7): 0000000000010101 STATUS (DR6): 0000000000000000
DR0: addr=0x0000000000601041, ref.count=1 DR1: addr=0x0000000000000000, ref.count=0
DR2: addr=0x0000000000000000, ref.count=0 DR3: addr=0x0000000000000000, ref.count=0
That is, before, DR7 was setup for watching a 2 byte region starting
at what's in DR0 (0x601040).
And after, DR7 is setup for watching a 1 byte region starting at
what's in DR0 (0x601041).
We always write DR0..DR3 before DR7, because if we enable a slot's
bits in DR7, you need to have already written the corresponding
DR0..DR3 registers -- the kernel rejects the DR7 write with EINVAL
otherwise.
The error shown above is the opposite scenario. When we try to write
0x601041 to DR0, DR7's bits still indicate intent of watching a 2-byte
region. That DR0/DR7 combination is invalid, because 0x601041 is
unaligned. To watch two bytes, we'd have to use two slots. So the
kernel errors out with EINVAL.
Fix this by always first clearing DR7, then writing DR0..DR3, and then
setting DR7's bits.
A little optimization -- if we're disabling the last watchpoint, then
we can clear DR7 just once. The changes to nat/i386-dregs.c make that
easier to detect, and as bonus, they make it a little easier to make
sense of DR7 in the debug logs, as we no longer need to remember we're
seeing stale bits.
Tested on x86_64 Fedora 20, native and GDBserver.
This adds an exhaustive test that switches between many different
combinations of watchpoint types and addresses and widths.

gdb/nat/
Native target backend files. Code that interfaces with the
host debug API. E.g., ptrace code, Windows debug API code,
procfs code should go here.
gdb/target/
Host-independent, target vector specific code (target_ops).

This patch adds support for the Intel(R) Advanced Vector
Extensions 512 (Intel(R) AVX-512) registers. Native and remote
debugging are covered by this patch.
Intel(R) AVX-512 is an extension to AVX to support 512-bit wide
SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31).
The number of available registers in 32-bit mode is still 8
(XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers
are aliased to the respective 256-bit YMM registers. The lower
128-bits are aliased to the respective 128-bit XMM registers.
There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit
mode and 64-bit mode.

Read branch trace data incrementally and extend the current trace rather than
discarding it and reading the entire trace buffer each time.
If the branch trace buffer overflowed, we can't extend the current trace so we
discard it and start anew by reading the entire branch trace buffer.

A natural fix would be to make xxx_get_debug_reg_state take an
inferior argument, but that doesn't work because of the case where we
detach breakpoints/watchpoints from the child fork, at a time there's
no inferior for the child fork at all. We do a nasty hack in
i386_inferior_data_get, but that relies on all callers pointing the
current inferior to the correct inferior, which isn't actually being
done by all callers, and I don't think we want to enforce that -- deep
in the bowls of linux-nat.c, there are many cases we resume lwps
behind the scenes, and it's be better to not have that code rely on
global state (as it doesn't today).
The fix is to decouple the watchpoints code from inferiors, making it
track target processes instead. This way, we can freely keep track of
the watchpoint mirrors for these processes behind the core's back.
Checkpoints also play dirty tricks with swapping the process behind
the inferior, so they get special treatment too in the patch (which
just amounts to calling a new hook). Instead of the old hack in
i386_inferior_data_get, where we returned a copy of the current
inferior's debug registers mirror, as soon as we detect a fork in the
target, we copy the debug register mirror from the parent to the child
process.
I don't have an old kernel handy to test, but I stepped through gdb doing
the watchpoint removal in the fork child in the watchpoint-fork test
seeing that the debug registers end up cleared in the child.
I didn't find the need for linux_nat_iterate_watchpoint_lwps. If
we use plain iterate_over_lwps instead, what happens is that
when removing watchpoints, that iterate_over_lwps doesn't actually
iterate over anything, since the fork child is not added to the
lwp list until later, at detach time, in linux_child_follow_fork.
And if we don't iterate over that lwp, we don't mark its debug
registers as needing update. But linux_child_follow_fork takes
care of doing that explicitly:
child_lp = add_lwp (inferior_ptid);
child_lp->stopped = 1;
child_lp->last_resume_kind = resume_stop;
make_cleanup (delete_lwp_cleanup, child_lp);
/* CHILD_LP has new PID, therefore linux_nat_new_thread is not called for it.
See i386_inferior_data_get for the Linux kernel specifics.
Ensure linux_nat_prepare_to_resume will reset the hardware debug
registers. It is done by the linux_nat_new_thread call, which is
being skipped in add_lwp above for the first lwp of a pid. */
gdb_assert (num_lwps (GET_PID (child_lp->ptid)) == 1);
if (linux_nat_new_thread != NULL)
linux_nat_new_thread (child_lp);
if (linux_nat_prepare_to_resume != NULL)
linux_nat_prepare_to_resume (child_lp);
ptrace (PTRACE_DETACH, child_pid, 0, 0);
so unless I'm missing something (quite possible) it ends up all
the same. But, the !detach-on-fork, and the "follow-fork child" paths
should also call linux_nat_new_thread, and they don't presently. It
seems to me in those cases we're not clearing debug regs correctly
when that's needed. Instead of copying that bit that works around
add_lwp bypassing the linux_nat_new_thread call, I thought it'd
be better to add an add_initial_lwp call to be used in the case we
really need to bypass linux_nat_new_thread, and make
add_lwp always call linux_nat_new_thread.
i386_cleanup_dregs is rewritten to forget about the current process
debug mirrors, which takes cares of other i386 ports. Only a couple
of extra tweaks here and there were needed, as some targets wheren't
actually calling i386_cleanup_dregs.
Tested on Fedora 17 x86_64 -m64/-m32.
GDBserver already fetches the i386_debug_reg_state from the right
process, and, it doesn't handle forks at all, so no fix is needed over
there.
