commit fa96cb382c12b099675c5cc238aaa7352a3fd3d7
Author: Pedro Alves <palves@redhat.com>

    Teach GDBserver's Linux backend about no unwaited-for children (TARGET_WAITKIND_NO_RESUMED).
    
    GDBserver currently hangs forever in waitpid if the leader thread
    exits before other threads, or if all resumed threads exit - e.g.,
    next over a thread exit with sched-locking on.  This is exposed by
    leader-exit.exp.  leader-exit.exp is part of a series of tests for a
    set of related problems.  See
    <http://www.sourceware.org/ml/gdb-patches/2011-10/msg00704.html>:
    
     "
     To recap, on the Linux kernel, ptrace/waitpid don't allow reaping the
     leader thread until all other threads in the group are reaped.  When
     the leader exits, it goes zombie, but waitpid will not return an exit
     status until the other threads are gone.  This is presently exercised
     by the gdb.threads/leader-exit.exp test.  The fix for that test, in
     linux-nat.c:wait_lwp, handles the case where we see the leader gone
     when we're stopping all threads to report an event to some other
     thread to the core.
    
     (...)
    
     The latter bit about not blocking if there no resumed threads in the
     process also applies to some other thread exiting, not just the main
     thread.  E.g., this test starts a thread, and runs to a breakpoint in
     that thread:
    
     ...
     (gdb) c

    This patch fixes the issues by implementing TARGET_WAITKIND_NO_RESUMED
    on GDBserver, similarly to what the patch above did for native
    Linux GDB.
    
    gdb.threads/leader-exit.exp now passes.
    
    gdb.threads/no-unwaited-for-left.exp now at least errors out instead
    of hanging:

     warning: Remote failure reply: E.No unwaited-for children left.

     (gdb) FAIL: gdb.threads/no-unwaited-for-left.exp: continue stops when the main thread exits
    
    The gdb.threads/non-ldr-exc-*.exp tests are skipped because GDBserver
    unfortunately doesn't support fork/exec yet, but I'm confident this
    fixes the related issues.
    
    I'm leaving modeling TARGET_WAITKIND_NO_RESUMED in the RSP for a
    separate pass.
    
    (BTW, in case of error in response to a vCont, it would be better for
    GDB to query the target for the current thread, or re-select one,
    instead of assuming current inferior_ptid is still the selected
    thread.)
    
    This implementation is a little different from GDB's, because I'm
    avoiding bringing in more of this broken use of waitpid(PID) into
    GDBserver.  Specifically, this avoids waitpid(PID) when stopping all
    threads.  There's really no need for wait_for_sigstop to wait for each
    LWP in turn.  Instead, with some refactoring, we make it reuse
    linux_wait_for_event.

    This patch adds a default manifest in to the final links performed by the Cygwin and MinGW targets.
    The manifest is necessary in order for the linked binaries to be executed in a Windows 8 environment.
    
    The manifest is added using a linker script so that this feature will be compiler-neutral.  The resource
    merging code in the linker means that if an application provides its own manifest then the default
    manifest will be ignored.
    
    	* configure.in (all_emul_extra_binaries): New variable.  Populated
    	by invoking configure.tgt.

    	by the configure script.
    	(ALL_EMUL_EXTRA_BINARIES): New variable.

    gdbserver/Windows: Rely purely on event info when handling DLL load event
    
    This is the GDBserver counterpart of a change we recently made in
    GDB to only rely on get_image_name to determine its name.
    
    This simplification, in turn, allows us to remove a fair amount of
    functions and globals which now become unused.
    
    gdb/gdbserver/ChangeLog:
    
    	* win32-low.c (psapi_get_dll_name,
    	* win32_CreateToolhelp32Snapshot): Delete.
    	(win32_CreateToolhelp32Snapshot, win32_Module32First)
    	(win32_Module32Next, load_toolhelp, toolhelp_get_dll_name):
    	Delete.
    	(handle_load_dll): Add function description.
    	Remove code using psapi_get_dll_name and toolhelp_get_dll_name.

    windows: Factorize handling of DLL load address offset
    
    This patch is a small cleanup that moves the magic 0x1000 offset
    to apply to a DLL's base address inside the win32_add_one_solib
    function, rather than delegate that reponsibility to its callers.
    
    gdb/gdbserver/ChangeLog:
    
    	* win32-low.c (win32_add_one_solib): Add 0x1000 to load_addr.
    	Add comment.
    	(win32_add_all_dlls): Remove 0x1000 offset applied to DLL
    	base address when calling win32_add_one_solib.
    	(handle_load_dll): Delete local variable load_addr.
    	Remove 0x1000 offset applied to DLL base address when calling
    	win32_add_one_solib.
    	(handle_unload_dll): Add comment.

    gdbserver/windows: Ignore DLL load/unload events during child initialization.
    
    This GDBserver patch mirrors a change made in GDB wich aims at
    simplifying DLL handling during the inferior initialization
    (process creation during the "run", or during an "attach").
    Instead of processing each DLL load event, which is sometimes
    incomplete, we ignore these events until the inferior has completed
    its startup phase, and then just iterate over all DLLs via
    EnumProcessModules.
    
    As a side-effect, it fixes a small bug where win32_ensure_ntdll_loaded
    was missing a 0x1000 offset in the DLL base address. This problem
    should only be visible on the 64bit version of Windows 8.1, since
    this is the only platform where win32_ensure_ntdll_loaded is actually
    needed.

    DWARF: Read constant-class addresses correctly
    
    Starting with DWARF version 4, the description of the DW_AT_high_pc
    attribute was amended to say:
    
       if it is of class constant, the value is an unsigned integer offset
       which when added to the low PC gives the address of the first
       location past the last instruction associated with the entity.
    
    A change was made in Apr 27th, 2012 to reflect that change:
    
      | commit 91da14142c0171e58a91ad58a32fd010b700e761
      | Author: Mark Wielaard <mjw@redhat.com>
      | Date:   Fri Apr 27 18:55:19 2012 +0000
      |
      |     * dwarf2read.c (dwarf2_get_pc_bounds): Check DW_AT_high_pc form to
      |     see whether it is an address or a constant offset from DW_AT_low_pc.
      |     (dwarf2_record_block_ranges): Likewise.
      |     (read_partial_die): Likewise.
    
    Unfortunately, this new interpretation is now used regardless of
    the CU's DWARF version. It turns out that one of WindRiver's compilers
    (FTR: Diabdata 4.4) is generating DWARF version 2 info with
    DW_AT_high_pc attributes improperly using the data4 form. Because of
    that, we miscompute all high PCs incorrectly. This leads to a lot of
    symtabs having overlapping ranges, which in turn causes havoc in
    pc-to-symtab-and-line translations.
    
    One visible effect is when inserting a breakpoint on a given function:
    
        (gdb) b world
        Breakpoint 1 at 0x4005c4
    
    The source location of the breakpoint is missing. The output should be:
    
        (gdb) b world
        Breakpoint 1 at 0x4005c8: file dw2-rel-hi-pc-world.c, line 24.
    
    What happens in this case is that the pc-to-SAL translation first
    starts be trying to find the symtab associated to our PC using
    each symtab's ranges. Because of the high_pc miscomputation,
    many symtabs end up matching, and the heuristic trying to select
    the most probable one unfortunately returns one that is unrelated
    (it really had no change in this case to do any better). Once we
    have the wrong symtab, the start searching the associated linetable,
    where the addresses are correct, thus finding no match, and therefore
    no SAL.
    
    This patch is an attempt at handling the situation as gracefully
    as we can, without guarantees.  It introduces a new function
    "attr_value_as_address" which uses the correct accessor for getting
    the value of a given attribute.  It then adjust the code throughout
    this unit to use this function instead of assuming that addresses always
    have the DW_FORM_addr format.
    
    It also fixes the original issue of miscomputing the high_pc
    by limiting the new interpretation of constant form DW_AT_high_pc
    attributes to units using DWARF version 4 or later.

    make "file" use the BFD cache better
    
    Right now the "file" command will discard the exec_bfd and then
    possibly open a new one.
    
    If this ends up reopening the same file, it can cause needless work by
    gdb -- destroying all the per-BFD data just to re-read it again.
    
    This patch changes the code to hold a reference to the old exec_bfd
    while opening the new one.
    
    The possible downside of this is a higher peak memory use.

    add short-circuit logic to elfread.c
    
    If minimal symbols have already been read into a per-BFD object, then
    a symbol reader can skip re-reading them.  This changes the ELF reader
    to do so.
    
    We only skip the work if the file is ELF+DWARF.  If it has stabs or
    mdebug sections, then I think extra information is computed during the
    minsym creation pass; and so we must still repeat it.  Eventually even
    this will go away, once all symbol types have switched to being
    progspace-independent.  In the meantime this has no negative effect --
    it is just a missing optimization for a small set of users.
    
    This change also required a somewhat non-obvious change to the OBJSTAT
    accounting code.  If a symbol reader skips re-reading minimal symbols,
    then the corresponding OBJSTAT will not be updated.  This leads to a
    test failure in gdb.base/maint.exp.
    
    To fix this, I've moved the needed stat field out of objfile and into
    the per-BFD object.

    move minimal symbols to per-bfd
    
    Now that minimal symbols are independent of the program space, we can
    move them to the per-BFD object.  This lets us save memory in the
    multi-inferior case; and, once the symbol readers are updated, time.
    
    The other prerequisite for this move is that all the objects referred
    to by the minimal symbols have a lifetime at least as long as the
    per-BFD object.  I think this is satisfied partially by this patch
    (moving the copied names there) and partially by earlier patches
    moving the demangled name hash.
    
    This patch contains a bit of logic to avoid creating new minimal
    symbols if they have already been read for a given BFD.  This allows
    us to avoid trying to update all the symbol readers for this
    condition.  At first glance this may seem like a hack, but some symbol
    readers mix psym and minsym reading, and would require logic just like
    this regardless -- and it is simpler and less error-prone to just do
    the work in a central spot.

    change minsyms not to be relocated at read-time
    
    This removes the runtime offsets from minsyms.  Instead, these offsets
    will now be applied whenever the minsym's address is computed.
    
    This patch redefines MSYMBOL_VALUE_ADDRESS to actually use the offsets
    from the given objfile.  Then, it updates all the symbol readers,
    changing them so that they do not add in the section offset when
    creating the symbol.
    
    This change also lets us remove relocation of minsyms from
    objfile_relocate1 and also msymbols_sort.

    start change to progspace independence
    
    This patch starts changing minimal symbols to be independent of the
    program space.
    
    Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS
    and changes all the code to use it.  This is needed so we can change
    gdb to apply the section offset when a minsym's address is computed,
    as opposed to baking the offsets into the symbol itself.
    
    A few spots still need the unrelocated address.  For these, we
    introduce MSYMBOL_VALUE_RAW_ADDRESS.
    
    As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS,
    which computes the address of a bound minimal symbol.  This just does
    the obvious thing with the fields.
    
    Note that this change does not actually enable program space
    independence.  That requires more changes to gdb.  However, to ensure
    that these changes compile properly, this patch does add the needed
    section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has
    no effect at runtime by multiplying the offset by 0.

    use bound_minsym as result for lookup_minimal_symbol et al
    
    This patch changes a few minimal symbol lookup functions to return a
    bound_minimal_symbol rather than a pointer to the minsym.  This change
    helps prepare gdb for computing a minimal symbol's address at the
    point of use.
    
    Note that this changes even those functions that ostensibly search a
    single objfile.  That was necessary because, in fact, those functions
    can search an objfile and its separate debug objfiles; and it is
    important for the caller to know in which objfile the minimal symbol
    was actually found.
    
    The bulk of this patch is mechanical.

    we change this macro to compute its value; this patch introduces a

    change minsym representation
    
    In a later patch we're going to change the minimal symbol address
    calculation to apply section offsets at the point of use.  To make it
    simpler to catch potential problem spots, this patch changes the
    representation of minimal symbols and introduces new
    minimal-symbol-specific variants of the various accessors.  This is
    necessary because it would be excessively ambitious to try to convert
    all the symbol types at once.
    
    The core of this change is just renaming a field in minimal_symbol;
    the rest is just a fairly mechanical rewording.

    introduce minimal_symbol_upper_bound
    
    This introduces minimal_symbol_upper_bound and changes various bits of
    code to use it.  Since this function is intimately tied to the
    implementation of minimal symbol tables, I believe it belongs in
    minsyms.c.
    
    The new function is extracted from find_pc_partial_function_gnu_ifunc.
    This isn't a "clean" move because the old function interleaved the
    caching and the computation; but this doesn't make sense for the new
    code.

    [Python] Make regexp collection printers work with typedefs as well.
    
    Consider the following type for which we would like to provide
    a pretty-printer and manage it via RegexpCollectionPrettyPrinter:
    
            typedef long time_t;
    
    Currently, this does not work because this framework only considers
    the type's tag name:
    
            typename = gdb.types.get_basic_type(val.type).tag
            if not typename:
                return None
    
    This patch extends it to use the type's name if the basic type
    does not have a tag name, thus allowing the framework to also
    work with typedefs like the above.
    
    gdb/ChangeLog:
    
            * python/lib/gdb/printing.py (RegexpCollectionPrettyPrinter):
            Use the type's name if its basic type does not have a tag.

    DWARF: Set enum type "flag_enum" and "unsigned" flags at type creation.
    
    Consider the following Ada code:
    
       --  An array whose index is an enumeration type with 128 enumerators.
       type Enum_T is (Enum_000, Enum_001, [...], Enum_128);
       type Table is array (Enum_T) of Boolean;
    
    When the compiler is configured to generate pure DWARF debugging info,
    trying to print type Table's description yields:
    
        ptype pck.table
        type = array (enum_000 .. -128) of boolean
    
    The expected output was:
    
        ptype pck.table
        type = array (enum_000 .. enum_128) of boolean
    
    The DWARF debugging info for our array looks like this:
    
        <1><44>: Abbrev Number: 5 (DW_TAG_array_type)
           <45>   DW_AT_name        : pck__table
           <50>   DW_AT_type        : <0x28>
        <2><54>: Abbrev Number: 6 (DW_TAG_subrange_type)
           <55>   DW_AT_type        : <0x5c>
           <59>   DW_AT_lower_bound : 0
           <5a>   DW_AT_upper_bound : 128
    
    The array index type is, by construction with the DWARF standard,
    a subrange of our enumeration type, defined as follow:
    
        <2><5b>: Abbrev Number: 0
        <1><5c>: Abbrev Number: 7 (DW_TAG_enumeration_type)
           <5d>   DW_AT_name        : pck__enum_t
           <69>   DW_AT_byte_size   : 1
        <2><6b>: Abbrev Number: 8 (DW_TAG_enumerator)
           <6c>   DW_AT_name        : pck__enum_000
           <7a>   DW_AT_const_value : 0
        [etc]
    
    Therefore, while processing these DIEs, the array index type ends
    up being a TYPE_CODE_RANGE whose target type is our enumeration type.
    But the problem is that we read the upper bound as a negative value
    (-128), which is then used as is by the type printer to print the
    array upper bound. This negative value explains the "-128" in the
    output.
    
    To understand why the range type's upper bound is read as a negative
    value, one needs to look at how it is determined, in read_subrange_type:
    
      orig_base_type = die_type (die, cu);
      base_type = check_typedef (orig_base_type);
      [... high is first correctly read as 128, but then ...]
      if (!TYPE_UNSIGNED (base_type) && (high & negative_mask))
        high |= negative_mask;
    
    The negative_mask is applied, here, because BASE_TYPE->FLAG_UNSIGNED
    is not set. And the reason for that is because the base_type was only
    partially constructed during the call to die_type. While the enum
    is constructed on the fly by read_enumeration_type, its flag_unsigned
    flag is only set later on, while creating the symbols corresponding to
    the enum type's enumerators (see process_enumeration_scope), after
    we've already finished creating our range type - and therefore too
    late.
    
    My first naive attempt at fixing this problem consisted in extracting
    the part in process_enumeration_scope which processes all enumerators,
    to generate the associated symbols, but more importantly set the type's
    various flags when necessary. However, this does not always work well,
    because we're still in the subrange_type's scope, and it might be
    different from the scope where the enumeration type is defined.
    
    So, instead, what this patch does to fix the issue is to extract
    from process_enumeration_scope the part that determines whether
    the enumeration type should have the flag_unsigned and/or the
    flag_flag_enum flags set. It turns out that, aside from the code
    implementing the loop, this part is fairly independent of the symbol
    creation. With that part extracted, we can then use it at the end
    of our enumeration type creation, to produce a type which should now
    no longer need any adjustment.
    
    Once the enumeration type produced is correctly marked as unsigned,
    the subrange type's upper bound is then correctly read as an unsigned
    value, therefore giving us an upper bound of 128 instead of -128.

    Whatever the comment about deprecated_xfer_memory referred to,

    eliminate target_ops->deprecated_xfer_memory
    
    As no target uses it anymore, it can finally go away.
    
    After removing the deprecated_xfer_memory handling from
    default_xfer_partial, we can delete the latter, because the only thing
    it does is delegate to the target beneath unconditionally, which is
    what the delegator installed by target-delegates.c will do for us if
    no to_xfer_partial method is installed.
    
    This was the last user of de_fault, so that goes away too.

    go32-nat.c: Don't install a deprecated_xfer_memory method
    
    This removes yet another instance of a deprecated_xfer_memory user.
    
    Unfortunately djgpp's write_child function takes a non-const buffer
    pointer, while GDB's xfer_partial api passes a const pointer.  To be
    const-correct, we need to copy that buffer to a non-const buffer, and
    pass the copy to write_child.  This is actually what
    target.c:default_xfer_partial itself does, when calling into the
    ops->deprecated_xfer_memory hook.

    DWARF: Add array DW_AT_bit_stride and DW_AT_byte_stride support
    
    Consider the following declarations in Ada...
    
       type Item is range -32 .. 31;
       for Item'Size use 6;
    
       type Table is array (Natural range 0 .. 4) of Item;
       pragma Pack (Table);
    
    ... which declare a packed array whose elements are 6 bits long.
    The debugger currently does not notice that the array is packed,
    and thus prints values of this type incorrectly. This can be seen
    in the "ptype" output:
    
        (gdb) ptype table
        type = array (0 .. 4) of foo.item
    
    Normally, the debugger should print:
    
        (gdb) ptype table
        type = array (0 .. 4) of foo.item <packed: 6-bit elements>
    
    The debugging information for this array looks like this:
    
            .uleb128 0xf    # (DIE (0x15c) DW_TAG_array_type)
            .long   .LASF9  # DW_AT_name: "pck__table"
            .byte   0x6     # DW_AT_bit_stride
            .long   0x1a9   # DW_AT_type
            .uleb128 0x10   # (DIE (0x16a) DW_TAG_subrange_type)
            .long   0x3b    # DW_AT_type
            .byte   0       # DW_AT_lower_bound
            .byte   0x4     # DW_AT_upper_bound
            .byte   0       # end of children of DIE 0x15c
    
    The interesting part is the DW_AT_bit_stride attribute, which tells
    the size of the array elements is 6 bits, rather than the normal
    element type's size.
    
    This patch adds support for this attribute by first creating
    gdbtypes.c::create_array_type_with_stride, which is an enhanced
    version of create_array_type taking an extra parameter as the stride.
    The old create_array_type can then be re-implemented very simply
    by calling the new create_array_type_with_stride.
    
    We can then use this new function from dwarf2read, to create
    arrays with or without stride.
    
    gdb/ChangeLog:
    
            * gdbtypes.h (create_array_type_with_stride): Add declaration.
            * gdbtypes.c (create_array_type_with_stride): New function,
            renaming create_array_type, but with an added parameter
            called "bit_stride".
            (create_array_type): Re-implement using
            create_array_type_with_stride.
            * dwarf2read.c (read_array_type): Add support for DW_AT_byte_stride
            and DW_AT_bit_stride attributes.
    
    gdb/testsuite/ChangeLog:
    
            * gdb.dwarf2/arr-stride.c: New file.
            * gdb.dwarf2/arr-stride.exp: New file.
    
    The test, relying purely on generating an assembly file, only
    verifies the type description of our array. But I was also
    able to verify manually that the debugger print values of these
    types correctly as well (which was not the case prior to this
    patch).

    The breakpoint that caused a stop is breakpoint 3, but GDB end up
    reporting (and running breakpoint commands of) "Breakpoint 2" instead.
    
    The issue is that the bpstat_check_breakpoint_conditions logic of
    "wrong thread" is missing the "wrong task" check.  This is usually
    harmless, because the thread hop code in infrun.c code that handles
    wrong-task-hitting-breakpoint does check for task-specific breakpoints
    (within breakpoint_thread_match):
    
          /* Check if a regular breakpoint has been hit before checking
             for a potential single step breakpoint.  Otherwise, GDB will
             not see this breakpoint hit when stepping onto breakpoints.  */
          if (regular_breakpoint_inserted_here_p (aspace, stop_pc))
    	{
    	  if (!breakpoint_thread_match (aspace, stop_pc, ecs->ptid))
    	    thread_hop_needed = 1;
    	}
    
    IOW, usually, when one only has a task specific breakpoint at a given
    address, things work correctly.  Put another task-specific or
    non-task-specific breakpoint there, and things break.
    
    A patch that eliminates the special thread hop code in infrun.c is
    what exposed this, as after that GDB solely relies on
    bpstat_check_breakpoint_conditions to know whether the right or wrong
    task hit a breakpoint.  IOW, given the latent bug, Ada task-specific
    breakpoints become non-task-specific, and that is caught by the
    testsuite, as:
    
     break break_me task 3

    Re-implement ia64-linux-nat.c::ia64_linux_xfer_partial
    
    [description of this patch and ChangeLog entry by Joel Brobecker]
    The recent implementation was questionable, and if it worked, it was
    only by chance because the requested length is large enough that only
    one read was sufficient.  Note that the implementation before that
    also made that assumption, in the form of only handling
    TARGET_OBJECT_UNWIND_TABLE xfer requests when offset was zero.

    Use 16-bit integer type for rl78 register pairs.
    
    This patch changes rl78-tdep.c so that a 16-bit type is used for
    register pairs instead of a pointer type as was previously the case.
    This will cause these register pairs to be displayed as integers
    instead of as a data address with a 0xf0000 ORed in.
    
    E.g. registers ax, bc, de, and hl might now be displayed like this:
    
        (gdb) info registers ax bc de hl
        ax             0x6      6
        bc             0x0      0
        de             0x10c3   4291
        hl             0x108d   423
    
    Whereas, before, they were displayed as follows:
    
        (gdb) info registers ax bc de hl
        ax             0xf0006  0xf0006
        bc             0xf0000  0xf0000
        de             0xf10c3  0xf10c3
        hl             0xf108d  0xf108d
    
    These pairs are 16 bit quantities and should be displayed as such.
    This change also affects the way that the banked register pairs are
    displayed.  Within GDB, the banked register pairs are named bank0_rp0,
    bank0_rp1, .., bank3_rp2, bank3_rp3.
    
    However, these register pairs need to be used as addresses in DWARF
    expressions.  I have added 16 pseudo registers corresponding to banked
    register pairs.  These new pseudo registers are all hidden from the
    user and have a pointer type.  Values from these registers are
    intended to be used in DWARF expressions.  Therefore,
    rl78_dwarf_reg_to_regnum() has been adjusted to return these new
    pseudo register numbers.
    
    I had a much simpler patch which only changed the types, but it showed
    a number of regressions due to integer values from the banked register
    pairs being used as part of an address expression.  This current patch
    shows no regressions and now displays values of register pairs
    correctly.
    
    	* rl78-tdep.c ( RL78_BANK0_RP0_PTR_REGNUM, RL78_BANK0_RP1_PTR_REGNUM)
    	(RL78_BANK0_RP2_PTR_REGNUM, RL78_BANK0_RP3_PTR_REGNUM)
    	(RL78_BANK1_RP0_PTR_REGNUM, RL78_BANK1_RP1_PTR_REGNUM)
    	(RL78_BANK1_RP2_PTR_REGNUM, RL78_BANK1_RP3_PTR_REGNUM)
    	(RL78_BANK2_RP0_PTR_REGNUM, RL78_BANK2_RP1_PTR_REGNUM)
    	(RL78_BANK2_RP2_PTR_REGNUM, RL78_BANK2_RP3_PTR_REGNUM)
    	(RL78_BANK3_RP0_PTR_REGNUM, RL78_BANK3_RP1_PTR_REGNUM)
    	(RL78_BANK3_RP2_PTR_REGNUM, RL78_BANK3_RP3_PTR_REGNUM):
    	New constants.
    	(rl78_register_type): Use a data pointer type for SP and
    	new pseudo registers mentioned above.  Use a 16 bit integer
    	type for all other register pairs.
    	(rl78_register_name, rl78_g10_register_name): Update for
    	new pseudo registers.
    	(rl78_pseudo_register_read): Likewise.
    	(rl78_pseudo_register_write): Likewise.
    	(rl78_dwarf_reg_to_regnum): Return register numbers representing
    	to the newly added pseudo registers.
