/* Define the register numbers to be used in Dwarf debugging information.
   The SVR4 reference port C compiler uses the following register numbers
   in its Dwarf output code:
	0 for %eax (gcc regno = 0)
	1 for %ecx (gcc regno = 2)
	2 for %edx (gcc regno = 1)
	3 for %ebx (gcc regno = 3)
	4 for %esp (gcc regno = 7)
	5 for %ebp (gcc regno = 6)
	6 for %esi (gcc regno = 4)
	7 for %edi (gcc regno = 5)
   The following three DWARF register numbers are never generated by
   the SVR4 C compiler or by the GNU compilers, but SDB on x86/svr4
   believes these numbers have these meanings.
	8  for %eip    (no gcc equivalent)
	9  for %eflags (gcc regno = 17)
	10 for %trapno (no gcc equivalent)
   It is not at all clear how we should number the FP stack registers
   for the x86 architecture.  If the version of SDB on x86/svr4 were
   a bit less brain dead with respect to floating-point then we would
   have a precedent to follow with respect to DWARF register numbers
   for x86 FP registers, but the SDB on x86/svr4 is so completely
   broken with respect to FP registers that it is hardly worth thinking
   of it as something to strive for compatibility with.
   The version of x86/svr4 SDB I have at the moment does (partially)
   seem to believe that DWARF register number 11 is associated with
   the x86 register %st(0), but that's about all.  Higher DWARF
   register numbers don't seem to be associated with anything in
   particular, and even for DWARF regno 11, SDB only seems to under-
   stand that it should say that a variable lives in %st(0) (when
   asked via an `=' command) if we said it was in DWARF regno 11,
   but SDB still prints garbage when asked for the value of the
   variable in question (via a `/' command).
   (Also note that the labels SDB prints for various FP stack regs
   when doing an `x' command are all wrong.)
   Note that these problems generally don't affect the native SVR4
   C compiler because it doesn't allow the use of -O with -g and
   because when it is *not* optimizing, it allocates a memory
   location for each floating-point variable, and the memory
   location is what gets described in the DWARF AT_location
   attribute for the variable in question.
   Regardless of the severe mental illness of the x86/svr4 SDB, we
   do something sensible here and we use the following DWARF
   register numbers.  Note that these are all stack-top-relative
   numbers.
	11 for %st(0) (gcc regno = 8)
	12 for %st(1) (gcc regno = 9)
	13 for %st(2) (gcc regno = 10)
	14 for %st(3) (gcc regno = 11)
	15 for %st(4) (gcc regno = 12)
	16 for %st(5) (gcc regno = 13)
	17 for %st(6) (gcc regno = 14)
	18 for %st(7) (gcc regno = 15)

   OLDX is the address as it was before break_out_memory_refs was called.
   In some cases it is useful to look at this to decide what needs to be done.

   It is always safe for this macro to do nothing.  It exists to recognize
   opportunities to optimize the output.

   For the 80386, we handle X+REG by loading X into a register R and
   using R+REG.  R will go in a general reg and indexing will be used.
   However, if REG is a broken-out memory address or multiplication,
   nothing needs to be done because REG can certainly go in a general reg.

/* Expand string move (memcpy) ot store (memset) operation.  Use i386 string

   Aligned move sequence:

     1) Prologue guard: Conditional that jumps up to epilogues for small
	blocks that can be handled by epilogue alone.  This is faster
	but also needed for correctness, since prologue assume the block
	is larger than the desired alignment.

	Optional dynamic check for size and libcall for large
	blocks is emitted here too, with -minline-stringops-dynamically.

     2) Prologue: copy first few bytes in order to get destination
	aligned to DESIRED_ALIGN.  It is emitted only when ALIGN is less
	than DESIRED_ALIGN and up to DESIRED_ALIGN - ALIGN bytes can be
	copied.  We emit either a jump tree on power of two sized
	blocks, or a byte loop.

     3) Main body: the copying loop itself, copying in SIZE_NEEDED chunks
	with specified algorithm.

     4) Epilogue: code copying tail of the block that is too small to be
	handled by main body (or up to size guarded by prologue guard).

  Misaligned move sequence

     1) missaligned move prologue/epilogue containing:
        a) Prologue handling small memory blocks and jumping to done_label
	   (skipped if blocks are known to be large enough)
	b) Signle move copying first DESIRED_ALIGN-ALIGN bytes if alignment is
           needed by single possibly misaligned move
	   (skipped if alignment is not needed)
        c) Copy of last SIZE_NEEDED bytes by possibly misaligned moves

     2) Zero size guard dispatching to done_label, if needed

     3) dispatch to library call, if needed,

     3) Main body: the copying loop itself, copying in SIZE_NEEDED chunks
	with specified algorithm.  */
