-+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.

-+ * This target hook describes the relative costs of RTL expressions.

-+ * available for examination in x, and the rtx code of the expression
-+ * in which it is contained, found in outer_code. code is the
-+ * expression code--redundant, since it can be obtained with GET_CODE
-+ * (x).
-+ *
-+ * In implementing this hook, you can use the construct COSTS_N_INSNS
-+ * (n) to specify a cost equal to n fast instructions.
-+ *
-+ * On entry to the hook, *total contains a default estimate for the
-+ * cost of the expression. The hook should modify this value as
-+ * necessary. Traditionally, the default costs are COSTS_N_INSNS (5)
-+ * for multiplications, COSTS_N_INSNS (7) for division and modulus
-+ * operations, and COSTS_N_INSNS (1) for all other operations.
-+ *
-+ * When optimizing for code size, i.e. when optimize_size is non-zero,
-+ * this target hook should be used to estimate the relative size cost
-+ * of an expression, again relative to COSTS_N_INSNS.
-+ *
-+ * The hook returns true when all subexpressions of x have been
-+ * processed, and false when rtx_cost should recurse.

-+/* 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 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
-+{

-+ 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.

-+/*
-+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.

-+From this it is possible to obtain the data types of the value and

-+STACK_SIZE is the number of bytes of arguments passed on the

-+convention is available in which functions that take a fixed number of

-+/* Passing Arguments in Registers */
-+
-+/*
-+A C expression that controls whether a function argument is passed
-+in a register, and which register.
-+
-+The arguments are CUM, which summarizes all the previous
-+arguments; MODE, the machine mode of the argument; TYPE,
-+the data type of the argument as a tree node or 0 if that is not known
-+(which happens for C support library functions); and NAMED,
-+which is 1 for an ordinary argument and 0 for nameless arguments that
-+correspond to '...' in the called function's prototype.
-+TYPE can be an incomplete type if a syntax error has previously
-+occurred.
-+
-+The value of the expression is usually either a reg RTX for the
-+hard register in which to pass the argument, or zero to pass the
-+argument on the stack.
-+
-+For machines like the VAX and 68000, where normally all arguments are
-+pushed, zero suffices as a definition.
-+
-+The value of the expression can also be a parallel RTX. This is
-+used when an argument is passed in multiple locations. The mode of the
-+of the parallel should be the mode of the entire argument. The
-+parallel holds any number of expr_list pairs; each one
-+describes where part of the argument is passed. In each
-+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
-+the offset in bytes into the entire argument of where this part starts.
-+As a special exception the first expr_list in the parallel
-+RTX may have a first operand of zero. This indicates that the entire
-+argument is also stored on the stack.
-+
-+The last time this macro is called, it is called with MODE == VOIDmode,
-+and its result is passed to the call or call_value
-+pattern as operands 2 and 3 respectively.
-+
-+The usual way to make the ISO library 'stdarg.h' work on a machine
-+where some arguments are usually passed in registers, is to cause
-+nameless arguments to be passed on the stack instead. This is done
-+by making FUNCTION_ARG return 0 whenever NAMED is 0.
-+
-+You may use the macro MUST_PASS_IN_STACK (MODE, TYPE)
-+in the definition of this macro to determine if this argument is of a
-+type that must be passed in the stack. If REG_PARM_STACK_SPACE
-+is not defined and FUNCTION_ARG returns nonzero for such an
-+argument, the compiler will abort. If REG_PARM_STACK_SPACE is

-+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
