8c56e11254 AIX: Change XML to use library-list-aix instead of library-list.
This is more consistent with what we do with other similar XML lists,
and avoids a potential confusion with the library-list XML list.

gdb/ChangeLog:

        * features/library-list-aix.dtd: Replace library-list by
        library-list-aix.
        * rs6000-nat.c: Replace library-list by library-list-aix
        throughout.
        * solib-aix.c: Likewise.

726ce67c26 darwin: warning resuming inferior after attach
This patch avoids a warning when resuming the execution of a program
that we attached to. For instance:

    (gdb) attach 29989
    (gdb) continue
    Continuing.
    warning: Mach error at "/[...]/darwin-nat.c:738" in function
             "darwin_resume_thread": (os/kern) failure (0x5)

The warning is relatively harmless, but worrisome for the average
user.  The warning comes from the fact that darwin_wait recorded
that the fake stop event corresponding to the suspend action was
caused by the main thread being suspended on a SIGTRAP. As a result
of this, when resuming the program's execution, we try to resume
the thread's execution as well.  This is where the issue occurs,
as the thread was not in fact suspended, thus triggering the warning.

gdb/ChangeLog:

        * darwin-nat.c (darwin_setup_fake_stop_event): New function.
        (darwin_attach): Adjust using darwin_setup_fake_stop_event.

fda184b639 darwin-nat.c: Do not use gdb_assert on system call outcomes.
There were many cases were we make a system call which could fail
due to reasons outside of the debugger control. We should handle
these situations a little more gracefully than triggering an
internal error.

gdb/ChangeLog:

        * darwin-nat.c (darwin_mourn_inferior): Replace call to
        gdb_assert by call to MACH_CHECK_ERROR.
        (darwin_attach_pid): Raise an error rather than a failed
        assertion when various system calls failed.  Report a warning
        instead of raising a failed assertion when PREV_NOT is not NULL
        after call to mach_port_request_notification.
        (darwin_ptrace_me): Raise an error rather than a failed
        assertion when read returns nonzero.

	(E_VR0_REGNUM, E_VR31_REGNUM, E_NUM_OF_V850E3V5_REGS): Define.
	(v850_abi, V850_ABI_GCC, V850_ABI_RH850): New enum and constants.
	(gdbarch_tdep): New struct.
	(v850e2_register_name): Use E_NUM_OF_V850E2_REGS instead of
	E_NUM_REGS.
	(v850e3v5_register_name): New function.
	(v850_register_type): v850e3v5 vector registers are 64-bits wide.
	(v850_use_struct_convention): Add `gdbarch' parameter.  Add new
	code handling the struct return conventions for the RH850 ABI.
	Update all callers.
	(v850_eight_byte_align_p): New function.

	(v850_gdbarch_init): Add ABI detection code.  Register
	v850e3v5_register_name for the v850e3v5 architecture.  Set the
	number of registers for v850e3v5.  Register
	v850_dbtrap_breakpoint_from_pc as appropriate.
	(_initialize_gdbarch_init): Registration bfd_arch_v850_rh850.

`save' and `restore' register groups.  Don't include SPL
	or SPH in these groups.
	(rl78_dwarf_reg_to_regnum):  Adjust mapping for
	RL78_PC_REGNUM.  Add mappings for RL78_PSW_REGNUM,
