-+If defined, a function that outputs the assembler code for entry to a
-+function.  The prologue is responsible for setting up the stack frame,
-+initializing the frame pointer register, saving registers that must be
-+saved, and allocating size additional bytes of storage for the
-+local variables.  size is an integer.  file is a stdio
-+stream to which the assembler code should be output.
-+
-+The label for the beginning of the function need not be output by this
-+macro.  That has already been done when the macro is run.
-+
-+To determine which registers to save, the macro can refer to the array
-+regs_ever_live: element r is nonzero if hard register
-+r is used anywhere within the function.  This implies the function
-+prologue should save register r, provided it is not one of the
-+call-used registers.  (TARGET_ASM_FUNCTION_EPILOGUE must likewise use
-+regs_ever_live.)
-+
-+On machines that have ``register windows'', the function entry code does
-+not save on the stack the registers that are in the windows, even if
-+they are supposed to be preserved by function calls; instead it takes
-+appropriate steps to ``push'' the register stack, if any non-call-used
-+registers are used in the function.
-+
-+On machines where functions may or may not have frame-pointers, the
-+function entry code must vary accordingly; it must set up the frame
-+pointer if one is wanted, and not otherwise.  To determine whether a
-+frame pointer is in wanted, the macro can refer to the variable
-+frame_pointer_needed.  The variable's value will be 1 at run
-+time in a function that needs a frame pointer.  (see Elimination).
-+
-+The function entry code is responsible for allocating any stack space
-+required for the function.  This stack space consists of the regions
-+listed below.  In most cases, these regions are allocated in the
-+order listed, with the last listed region closest to the top of the
-+stack (the lowest address if STACK_GROWS_DOWNWARD is defined, and
-+the highest address if it is not defined).  You can use a different order
-+for a machine if doing so is more convenient or required for
-+compatibility reasons.  Except in cases where required by standard
-+or by a debugger, there is no reason why the stack layout used by GCC
-+need agree with that used by other compilers for a machine.

-+/* Routines for manipulation of the constant pool.  */

-+/* AVR32 instructions cannot load a large constant directly into a
-+   register; they have to come from a pc relative load.  The constant
-+   must therefore be placed in the addressable range of the pc
-+   relative load.  Depending on the precise pc relative load
-+   instruction the range is somewhere between 256 bytes and 4k.  This
-+   means that we often have to dump a constant inside a function, and
-+   generate code to branch around it.
-+
-+   It is important to minimize this, since the branches will slow
-+   things down and make the code larger.
-+
-+   Normally we can hide the table after an existing unconditional
-+   branch so that there is no interruption of the flow, but in the
-+   worst case the code looks like this:
-+
-+	lddpc	rn, L1
-+	...
-+	rjmp	L2
-+	align
-+	L1:	.long value
-+	L2:
-+	...
-+
-+	lddpc	rn, L3
-+	...
-+	rjmp	L4
-+	align
-+	L3:	.long value
-+	L4:
-+	...
-+
-+   We fix this by performing a scan after scheduling, which notices
-+   which instructions need to have their operands fetched from the
-+   constant table and builds the table.
-+
-+   The algorithm starts by building a table of all the constants that
-+   need fixing up and all the natural barriers in the function (places
-+   where a constant table can be dropped without breaking the flow).
-+   For each fixup we note how far the pc-relative replacement will be
-+   able to reach and the offset of the instruction into the function.
-+
-+   Having built the table we then group the fixes together to form
-+   tables that are as large as possible (subject to addressing
-+   constraints) and emit each table of constants after the last
-+   barrier that is within range of all the instructions in the group.
-+   If a group does not contain a barrier, then we forcibly create one
-+   by inserting a jump instruction into the flow.  Once the table has
-+   been inserted, the insns are then modified to reference the
-+   relevant entry in the pool.
-+
-+   Possible enhancements to the algorithm (not implemented) are:
-+
-+   1) For some processors and object formats, there may be benefit in
-+   aligning the pools to the start of cache lines; this alignment
-+   would need to be taken into account when calculating addressability
-+   of a pool.  */

-+#define STRICT_ALIGNMENT 1
-+
-+/*
-+Define this if you wish to imitate the way many other C compilers handle
-+alignment of bit-fields and the structures that contain them.
-+
-+The behavior is that the type written for a bit-field (int,
-+short, or other integer type) imposes an alignment for the
-+entire structure, as if the structure really did contain an ordinary
-+field of that type.  In addition, the bit-field is placed within the
-+structure so that it would fit within such a field, not crossing a
-+boundary for it.
-+
-+Thus, on most machines, a bit-field whose type is written as int
-+would not cross a four-byte boundary, and would force four-byte
-+alignment for the whole structure.  (The alignment used may not be four
-+bytes; it is controlled by the other alignment parameters.)
-+
-+If the macro is defined, its definition should be a C expression;
-+a nonzero value for the expression enables this behavior.
-+
-+Note that if this macro is not defined, or its value is zero, some
-+bit-fields may cross more than one alignment boundary.  The compiler can
-+support such references if there are insv, extv, and
-+extzv insns that can directly reference memory.
-+
-+The other known way of making bit-fields work is to define
-+STRUCTURE_SIZE_BOUNDARY as large as BIGGEST_ALIGNMENT.
-+Then every structure can be accessed with fullwords.
-+
-+Unless the machine has bit-field instructions or you define
-+STRUCTURE_SIZE_BOUNDARY that way, you must define
-+PCC_BITFIELD_TYPE_MATTERS to have a nonzero value.
-+
-+If your aim is to make GCC use the same conventions for laying out
-+bit-fields as are used by another compiler, here is how to investigate
-+what the other compiler does.  Compile and run this program:
-+
-+struct foo1
-+{
-+  char x;
-+  char :0;
-+  char y;
-+};
-+
-+struct foo2
-+{
-+  char x;
-+  int :0;
-+  char y;
-+};
-+
-+main ()
-+{
-+  printf ("Size of foo1 is %d\n",
-+          sizeof (struct foo1));
-+  printf ("Size of foo2 is %d\n",
-+          sizeof (struct foo2));
-+  exit (0);
-+}
-+
-+If this prints 2 and 5, then the compiler's behavior is what you would
-+get from PCC_BITFIELD_TYPE_MATTERS.

-+
-+#define HARD_REGNO_NREGS(REGNO, MODE)            \

-+  ((unsigned int)((GET_MODE_SIZE(MODE) + UNITS_PER_WORD -1 ) / UNITS_PER_WORD))
-+
-+/*
-+A C expression that is nonzero if it is permissible to store a value
-+of mode MODE in hard register number REGNO (or in several
-+registers starting with that one).  For a machine where all registers
-+are equivalent, a suitable definition is
-+
-+  #define HARD_REGNO_MODE_OK(REGNO, MODE) 1
-+
-+You need not include code to check for the numbers of fixed registers,
-+because the allocation mechanism considers them to be always occupied.
-+
-+On some machines, double-precision values must be kept in even/odd
-+register pairs.  You can implement that by defining this macro to reject
-+odd register numbers for such modes.
-+
-+The minimum requirement for a mode to be OK in a register is that the
-+mov[mode] instruction pattern support moves between the
-+register and other hard register in the same class and that moving a
-+value into the register and back out not alter it.
-+
-+Since the same instruction used to move word_mode will work for
-+all narrower integer modes, it is not necessary on any machine for
-+HARD_REGNO_MODE_OK to distinguish between these modes, provided
-+you define patterns movhi, etc., to take advantage of this.  This
-+is useful because of the interaction between HARD_REGNO_MODE_OK
-+and MODES_TIEABLE_P; it is very desirable for all integer modes
-+to be tieable.
-+
-+Many machines have special registers for floating point arithmetic.
-+Often people assume that floating point machine modes are allowed only
-+in floating point registers.  This is not true.  Any registers that
-+can hold integers can safely hold a floating point machine
-+mode, whether or not floating arithmetic can be done on it in those
-+registers.  Integer move instructions can be used to move the values.
-+
-+On some machines, though, the converse is true: fixed-point machine
-+modes may not go in floating registers.  This is true if the floating
-+registers normalize any value stored in them, because storing a
-+non-floating value there would garble it.  In this case,
-+HARD_REGNO_MODE_OK should reject fixed-point machine modes in
-+floating registers.  But if the floating registers do not automatically
-+normalize, if you can store any bit pattern in one and retrieve it
-+unchanged without a trap, then any machine mode may go in a floating
-+register, so you can define this macro to say so.
-+
-+The primary significance of special floating registers is rather that
-+they are the registers acceptable in floating point arithmetic
-+instructions.  However, this is of no concern to
-+HARD_REGNO_MODE_OK.  You handle it by writing the proper
-+constraints for those instructions.
-+
-+On some machines, the floating registers are especially slow to access,
-+so that it is better to store a value in a stack frame than in such a
-+register if floating point arithmetic is not being done.  As long as the
-+floating registers are not in class GENERAL_REGS, they will not
-+be used unless some pattern's constraint asks for one.

-+expr_list the first operand must be a reg RTX for the hard
-+register in which to pass this part of the argument, and the mode of the
-+register RTX indicates how large this part of the argument is.  The
-+second operand of the expr_list is a const_int which gives

-+
-+It usually pays to define several simpler macros to serve as
-+subroutines for this one.  Otherwise it may be too complicated to
-+understand.
-+
-+This macro must exist in two variants: a strict variant and a
-+non-strict one.  The strict variant is used in the reload pass.  It
-+must be defined so that any pseudo-register that has not been
-+allocated a hard register is considered a memory reference.  In
-+contexts where some kind of register is required, a pseudo-register
-+with no hard register must be rejected.
-+
-+The non-strict variant is used in other passes.  It must be defined to
-+accept all pseudo-registers in every context where some kind of
-+register is required.
-+
-+Compiler source files that want to use the strict variant of this
-+macro define the macro REG_OK_STRICT.  You should use an
-+#ifdef REG_OK_STRICT conditional to define the strict variant
-+in that case and the non-strict variant otherwise.
-+
-+Subroutines to check for acceptable registers for various purposes (one
-+for base registers, one for index registers, and so on) are typically
-+among the subroutines used to define GO_IF_LEGITIMATE_ADDRESS.
-+Then only these subroutine macros need have two variants; the higher
-+levels of macros may be the same whether strict or not.
-+
-+Normally, constant addresses which are the sum of a symbol_ref
-+and an integer are stored inside a const RTX to mark them as
-+constant.  Therefore, there is no need to recognize such sums
-+specifically as legitimate addresses.  Normally you would simply
-+recognize any const as legitimate.
-+
-+Usually PRINT_OPERAND_ADDRESS is not prepared to handle constant
-+sums that are not marked with  const.  It assumes that a naked
-+plus indicates indexing.  If so, then you must reject such
-+naked constant sums as illegitimate addresses, so that none of them will
-+be given to PRINT_OPERAND_ADDRESS.
-+
-+On some machines, whether a symbolic address is legitimate depends on
-+the section that the address refers to.  On these machines, define the
-+macro ENCODE_SECTION_INFO to store the information into the
-+symbol_ref, and then check for it here.  When you see a
-+const, you will have to look inside it to find the
-+symbol_ref in order to determine the section.
-+
-+The best way to modify the name string is by adding text to the
-+beginning, with suitable punctuation to prevent any ambiguity.  Allocate
-+the new name in saveable_obstack.  You will have to modify
-+ASM_OUTPUT_LABELREF to remove and decode the added text and
-+output the name accordingly, and define STRIP_NAME_ENCODING to
-+access the original name string.
-+
-+You can check the information stored here into the symbol_ref in
-+the definitions of the macros GO_IF_LEGITIMATE_ADDRESS and
-+PRINT_OPERAND_ADDRESS.
