609c3040c2 [nto] Fixes for nto procfs.
Fix errnoeus construction of procfs path. The issue is, after the first
info pidlist or first run, the path for local node (the most common node)
will be reset to empty which makes subsequent queries and runs impossible.

gdb/ChangeLog:

	* nto-procfs.c (nto_procfs_path): Rename to...
	(nodestr): ... this, and change type.
	(nto_node): Use new variable and logic accordingly.
	(procfs_open_1): Use new variable name. Use local buffer to construct
	procfrs path.
	(procfs_pidlist): Use NODESTR to construct procfs path.
	(procfs_files_info): Use NODESTR to output meaningful text.
	(do_attach): Construct procfs using NODESTR.
	(procfs_create_inferior): Compare pointer to NULL.

edeefb6792 Add --enable-compressed-debug-sections={all,gas,gold,ld}
This patch removes the gas configure option:

--enable-compressed-debug-sections

and adds a toplevel configure option:

--enable-compressed-debug-sections={all,gas,gold,ld}

to enable compressed debug sections for gas, gold or ld by default.  At
the moment, this configure option is ignored by gold and ld.  For x86
Linux targets, default to compressing debug sections in gas.

	PR gas/19109
	* configure.ac: Add
	--enable-compressed-debug-sections={all,gas,gold,ld}.
	* configure: Regenerated.

bfd09d203f gdb: Improve syscall entry/return tracking on Linux
The existing logic was simply to flip syscall entry/return state when a
syscall trap was seen, and even then only with active 'catch syscall'.
That can get out of sync if 'catch syscall' is toggled at odd times.

This patch updates the entry/return state for all syscall traps,
regardless of catching state, and also updates known syscall state for
other kinds of traps.  Almost all PTRACE_EVENT stops are delivered from
the middle of a syscall, so this can act like an entry.  Every other
kind of ptrace stop is only delivered outside of syscall event pairs, so
marking them ignored ensures the next syscall trap looks like an entry.

Three new test scenarios are added to catch-syscall.exp:

- Disable 'catch syscall' from an entry to deliberately miss the return
  event, then re-enable to make sure a new entry is recognized.

- Enable 'catch syscall' for the first time from a vfork event, which is
  a PTRACE_EVENT_VFORK in the middle of the syscall.  Make sure the next
  syscall event is recognized as the return.

- Make sure entry and return are recognized for an ENOSYS syscall.  This
  is to defeat a common x86 hack that uses the pre-filled ENOSYS return
  value as a sign of being on the entry side.

2015-10-19  Josh Stone  <jistone@redhat.com>

	* linux-nat.c (linux_handle_syscall_trap): Always update entry/
	return state, even when not actively catching syscalls at all.

This behavior shows up whenever GDB is in all-stop mode and is handling
target-initiated File-I/O requests, in the middle of, say, a continue
request.

When GDB is done handling the File-I/O request, it doesn't set
rs->waiting_for_stop_reply back to 1, meaning GDB should wait for
further target events.

This seems to be a latent bug, because in the past this didn't really
cause any issues. But it seems to have been uncovered by commit
567420d108, which explicitly checks
for rs->waiting_for_stop_reply == 0, triggering the failures above.

The following patch fixes this by reorganizing the setting of
rs->waiting_for_stop_reply.

8d689ee570 aarch64 multi-arch part 6: HW breakpoint on unaligned address
Nowadays, both aarch64 GDB and linux kernel assumes that address for
setting breakpoint should be 4-byte aligned.  However that is not true
after we support multi-arch, because thumb instruction can be at 2-byte
aligned address.  Patch http://lists.infradead.org/pipermail/linux-arm-kernel/2015-October/375141.html
to linux kernel is to teach kernel to handle 2-byte aligned address for
HW breakpoint, while this patch is to teach aarch64 GDB handle 2-byte
aligned address.

First of all, we call gdbarch_breakpoint_from_pc to get the instruction
length rather than using hard-coded 4.  Secondly, in GDBserver, we set
length back to 2 if it is 3, because GDB encode 3 in it to indicate it
is a 32-bit thumb breakpoint.  Then we relax the address alignment
check from 4-byte aligned to 2-byte aligned.

This patch enables some tests (such as gdb.base/break-idempotent.exp,
gdb.base/cond-eval-mode.exp, gdb.base/watchpoint-reuse-slot.exp,) and
fixes many fails (such as gdb.base/hbreak2.exp) when the program is
compiled in thumb mode on aarch64.

Regression tested on aarch64-linux, both native and gdbserver.  This
is the last patch of multi-arch work.

6448a3e4da Define enum out of struct
This patch moves the definition of enum out of the scope of struct
aarch64_memory_operand, otherwise it breaks GDB build in c++ mode.

	* arch/aarch64-insn.h (struct aarch64_memory_operand): Move enum
	out of it.
	(enum aarch64_memory_operand_type): New.
