Yao Qi c4d9ceb647 Honour SIGILL and SIGSEGV in cancel breakpoint and event lwp selection
I see the following fail on arm-none-linux-gnueabi testing,

(gdb) continue^M
Continuing.^M
^M
Program received signal SIGILL, Illegal instruction.^M
[Switching to Thread 1003]^M
handler (signo=10) at
/scratch/yqi/arm-none-linux-gnueabi/src/gdb-trunk/gdb/testsuite/gdb.threads/sigstep-threads.c:33^M
33        tgkill (getpid (), gettid (), SIGUSR1);       /* step-2 */^M
(gdb) FAIL: gdb.threads/sigstep-threads.exp: continue

the cause is that GDBserver doesn't cancel the breakpoint if the stop
signal is SIGILL.  The kernel used here is a little old, 2.6.x, and
doesn't translate SIGILL to SIGTRAP when program hits breakpoint
instruction (which is an illegal instruction actually).  GDB and
GDBserver can translate SIGILL to SIGTRAP under certain circumstance,
so it is not a problem here.  See gdbserver/linux-low.c:linux_wait_1

  /* If this event was not handled before, and is not a SIGTRAP, we
     report it.  SIGILL and SIGSEGV are also treated as traps in case
     a breakpoint is inserted at the current PC.  If this target does
     not support internal breakpoints at all, we also report the
     SIGTRAP without further processing; it's of no concern to us.  */
  maybe_internal_trap
    = (supports_breakpoints ()
       && (WSTOPSIG (w) == SIGTRAP
	   || ((WSTOPSIG (w) == SIGILL
		|| WSTOPSIG (w) == SIGSEGV)
	       && (*the_low_target.breakpoint_at) (event_child->stop_pc))));

However, SIGILL and SIGSEGV is not considered when cancelling
breakpoint, which causes the fail above.  That is, when GDB is doing
software single step on address ADDR, both thread A and thread B hits the
software single step breakpoint, and get SIGILL.  GDB selects the event
from thread A, removes the software single step breakpoint, and resume
the program.  The event (SIGILL) from thread B is reported to GDB, but
GDB doesn't regard this SIGILL as SIGTRAP, because the breakpoint on
address ADDR was removed, so GDB reports "Program received signal
SIGILL".

The patch is to allow calling cancel_breakpoint if the signal is
SIGILL and SIGSEGV.  This patch fixes the fail above.  Likewise, event
lwp selection should honour SIGILL and SIGSEGV too.

Don Breazeal 89a5711c56 Refactor ptrace extended event status.
This commit implements functions for identifying and extracting extended
ptrace event information from a Linux wait status.  These are just
convenience functions intended to hide the ">> 16" used to extract the
event from the wait status word, replacing the hard-coded shift with a more
descriptive function call.  This is preparatory work for implementation of
follow-fork and detach-on-fork for extended-remote linux targets.

	linux_ptrace_get_extended_event.

Joel Brobecker bffc0964c7 Fix CPPFLAGS handling in gdbserver's build.
In gdb/gdbserver/Makefile.in, IPAGENT_CFLAGS is defined using
an expression which references $(CPPFLAGS). But CPPFLAGS isn't
actually defined.

This patch first adds a CPPFLAGS definition, so as to inherit
the value passed at configure time (if any). And it then makes it
part of INTERNAL_CFLAGS_BASE, instead. There is no reason that
CPPFLAGS be useful for a certain class of source files, and not
the rest. This is also consistent with what's done in GDB.

gdb/gdbserver/ChangeLog:

        * Makefile.in (CPPFLAGS): Define.
        (INTERNAL_CFLAGS_BASE): Add ${CPPFLAGS}.
        (IPAGENT_CFLAGS): Remove ${CPPFLAGS}.

Tested by rebuilding GDBserver with a dummy CPPFLAGS, and verifying
that the compilation command was altered as expected.

Gary Benson 0bfdf32fa1 Rename current_inferior as current_thread in gdbserver
GDB has a function named "current_inferior" and gdbserver has a global
variable named "current_inferior", but the two are not equivalent;
indeed, gdbserver does not have any real equivalent of what GDB calls
an inferior.  What gdbserver's "current_inferior" is actually pointing
to is a structure describing the current thread.  This commit renames
current_inferior as current_thread in gdbserver to clarify this.  It
also renames the function "set_desired_inferior" to "set_desired_thread"
and renames various local variables from foo_inferior to foo_thread.

Gary Benson c5e92cca56 Introduce show_debug_regs
This commit adds a new global flag show_debug_regs to common-debug.h
to replace the flag debug_hw_points used by gdbserver and by the
Linux x86 and AArch64 ports, and to replace the flag maint_show_dr
used by the Linux MIPS port.

Note that some debug printing in the AArch64 port was enabled only if
debug_hw_points > 1 but no way to set debug_hw_points to values other
than 0 and 1 was provided; that code was effectively dead.  This
commit enables all debug printing if show_debug_regs is nonzero, so
the AArch64 output will be more verbose than previously.

gdb/ChangeLog:

	* common/common-debug.h (show_debug_regs): Declare.
	* common/common-debug.c (show_debug_regs): Define.
	* aarch64-linux-nat.c (debug_hw_points): Don't define.  Replace

This patch fixes the routines to collect and supply ptrace registers on ppc64le

James Hogan ac740bc7a9 Reset errno before PTRACE_PEEKUSER for MIPS DSP_CONTROL
PTRACE_PEEKUSER can return -1, which is usually used to determine whether
a system call has reported an error, so errno must be used alone to
determine whether an error occurred. However errno isn't modified by a
successful system call so it must be reset to a known value (0) before the
syscall call.

Add the missing errno reset when reading the DSP_CONTROL register in the
native MIPS Linux backend and the MIPS gdbserver backend.

gdb/:
	* mips-linux-nat.c (mips_linux_read_description): Reset errno to 0
	prior to reading DSP_CONTROL with PTRACE_PEEKUSER ptrace call.

gdb/gdbserver/:
	* linux-mips-low.c (mips_read_description): Reset errno to 0 prior
	to reading DSP_CONTROL with PTRACE_PEEKUSER ptrace call.

Gary Benson 97ea6506c4 x86 debug address register clarifications
The loop macro ALL_DEBUG_REGISTERS does not iterate over the status or
control registers, so its name is misleading.  This commit renames it
as ALL_DEBUG_ADDRESS_REGISTERS and updates all uses.  This commit also
updates its loop conditions to an equivalent but better form, and
makes two functions use it that had previously hardwired the loop.
A comment on a related field in the x86_debug_reg_state structure is
also updated to reflect that the field refers specifically to address
registers only.

gdb/ChangeLog:

	* nat/x86-dregs.h (ALL_DEBUG_REGISTERS): Renamed as...
	(ALL_DEBUG_ADDRESS_REGISTERS): New macro.  All uses updated.
	Loop conditions	changed to equivalent form.
	(struct x86_debug_reg_state): Updated dr_ref_count comment.

Gary Benson df7e526582 Rename 32- and 64-bit Intel files from "i386" to "x86"
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.

gdb/ChangeLog:

	* i386-nat.h: Renamed as...

Gary Benson 860789c7d5 Use exceptions and cleanups in gdbserver
This commit replaces the hacky "exception" system in gdbserver with
the exceptions and cleanups subsystem from GDB.

Only the catch/cleanup code in what was "main" has been updated to
use the new system.  Other parts of gdbserver can now be converted
to use TRY_CATCH and cleanups on an as-needed basis.

A side-effect of this commit is that some error messages will change
slightly, and in cases with multiple errors the error messages will
be printed in a different order.

Gary Benson 14ce319239 Convert fatal to perror_with_name in IPA code
This commit converts four calls to fatal into calls to
perror_with_name.  perror_with_name calls error, which
in IPA terminates with exit (1) rather than longjmp, so
there is no functional change here.

Gary Benson 50278d599d Convert fatal to error in remote_prepare
This commit converts a call to fatal in remote_prepare with a call to
error.  remote_prepare is called precisely once, from main, at a point
where jumping to toplevel will call exit (1), so error and fatal are
functionally equivalent at this point.  Note that remote_prepare calls
perror_with_name (which calls error) so callers of remote_prepare must
already handle the fact that it may exit via longjmp.

gdb/gdbserver/ChangeLog:

	* remote-utils.c (remote_prepare): Replace fatal with error.

Gary Benson aa96c426c6 Downgrade fatal to warning in linux_async
This commit downgrades a fatal error to a warning in linux_async.
linux_async is called from two different places in gdbserver:

 Via target_async from handle_accept_event.  The argument
   is always zero, so the warning will never be printed here.

 Via start_non_stop from handle_general_set.  This prints
   its own error message to stderr on failure, which will
   be preceded by the warning if it is emitted.

gdb/gdbserver/ChangeLog:

	* linux-low.c (linux_async): Replace fatal with warning.
	Tidy up and return.
	(linux_start_non_stop): Return -1 if linux_async failed.

Gary Benson f7160e9741 Convert fatal to gdb_assert in both i386_dr_low_set_addr
This commit converts if..fatal checks in both i386_dr_low_set_addr
implementations to gdb_asserts.  It's not obvious from the context,
but the conditional in both cases is changed to match the equivalent
conditional in the i386_dr_low_get_addr implementations.  Nothing
fundamental has changed because DR_FIRSTADDR is zero.  This commit
also removes a vague comment in Linux i386_dr_low_get_addr.  I could
have reworded the comment (and replicated it three times for the other
identical assertions) but I think the existence of specific functions
for the status and control registers makes it fairly obvious what is
going on.

gdb/gdbserver/ChangeLog:

	* linux-x86-low.c (i386_dr_low_set_addr): Replace check with

	(i386_dr_low_get_addr): Remove vague comment.

Gary Benson 34abf635b3 Introduce common-debug.h
This introduces common-debug.h.  This holds the functions debug_printf
and debug_vprintf, two functions that the common code can use to print
debugging messages.  Clients of the common code are expected to
implement debug_vprintf; a debug_vprintf function is written from
scratch for GDB, and gdbserver's existing debug_printf is repurposed
as debug_vprintf.

common/agent.c is changed to use debug_vprintf rather than
defining the macro DEBUG_AGENT depending on GDBSERVER.

nat/i386-dregs.c is changed to use the externally-implemented
debug_printf, rather than defining it itself.

Gary Benson 9239eeabe3 Introduce common-types.h
This introduces common-types.h.  This file defines various standard
types used by gdb and gdbserver.

Currently these types are conditionally defined based on GDBSERVER.
The long term goal is to remove all such tests; however, this is
difficult as currently gdb uses definitions from BFD.  In the meantime
this is still a step in the right direction.

Gary Benson bb974a2493 Move errno.h to common-defs.h
This commit moves the inclusion of errno.h to common-defs.h and
removes all other inclusions.  Note that prior to this commit
server.h included errno.h protected by "#ifdef HAVE_ERRNO_H".
This protection was added with the Windows CE port, which is
currently broken.  Since no other platform needs this, I have
removed the protection and the configury to support it.

Gary Benson 976411d6b6 Introduce common/common-defs.h
This commit creates a new header, common/common-defs.h, to hold
definitions common to all code under gdb/.  Both gdb/defs.h and
gdb/gdbserver/server.h are modified to include common-defs.h as
their first non-comment line; all code under gdb/ includes either
defs.h or server.h as appropriate, so common-defs.h will be the
first actual code the compiler sees.

For this initial commit common-defs.h includes only the two
config.h files.  Future commits will move more code currently
duplicated across defs.h and server.h such that shared code in
gdb/{common,target,nat} can be modified to include common-defs.h
rather than defs.h or server.h.

Gary Benson d41f6d8ea2 Make all source files include defs.h or server.h first
This commit makes all source files under gdb/ that include headers
from gdb/ include either defs.h or server.h before any other code.
This ensures that definitions and macros from the two config.h files
are always in place for our code.  An exception has been made for
gdb/gdbserver/gdbreplay.c which seems to be a special case.

gdb/
2014-07-30  Gary Benson  <gbenson@redhat.com>

	* btrace.c: Include defs.h.
	* common/ptid.c: Include defs.h or server.h as appropriate.
	* nat/mips-linux-watch.c: Likewise.

gdb/gdbserver/
2014-07-30  Gary Benson  <gbenson@redhat.com>

	* hostio-errno.c: Move server.h to top of includes list.
	* inferiors.c: Likewise.
	* linux-x86-low.c: Likewise.
	* notif.c: Include server.h.

Tom Tromey 314c6a3559 Make gdbserver CORE_ADDR unsigned
gdbserver defines CORE_ADDR to be signed.  This seems erroneous to
me; and furthermore likely to cause problems in common/, as it is
different from gdb's definition.

	* server.h (CORE_ADDR): Now unsigned.
