++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

++#define HARD_REGNO_NREGS(REGNO, MODE)            \
++   ((GET_MODE_SIZE (MODE) + UNITS_PER_WORD - 1)  \

++*/
++#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.

++
++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.

+-@opindex mid-shared-library
+-Generate code that supports shared libraries via the library ID method.
+-This allows for execute in place and shared libraries in an environment
+-without virtual memory management.  This option implies @option{-fPIC}.
++@item -mhard-float
++@opindex mhard-float

+ 
+-@item -mshared-library-id=n
+-@opindex mshared-library-id
+-Specified the identification number of the ID based shared library being
+-compiled.  Specifying a value of 0 will generate more compact code, specifying
+-other values will force the allocation of that number to the current
+-library but is no more space or time efficient than omitting this option.
++@item -mrelax
++@opindex mrelax
++Enable relaxing in linker. This means that when the address of symbols
++are known at link time, the linker can optimize @samp{icall} and @samp{mcall}
++instructions into a @samp{rcall} instruction if possible. Loading the address
++of a symbol can also be optimized.

++When using gcc as a frontend for linking this switch forces the use of
++@samp{fake} system calls in the newlib c-library. These fake system
++calls are handled by some AVR32 simulators which redirects these calls
++to the OS in which the simulator is running. This is practical for
++being able to perform file I/O when running programs in a simulator.

++@item -mforce-double-align
++@opindex mforce-double-align
++Force double-word alignment for double-word memory accesses.

+-@opindex mlong-calls
+-@opindex mno-long-calls
+-Tells the compiler to perform function calls by first loading the
+-address of the function into a register and then performing a subroutine
+-call on this register.  This switch is needed if the target function
+-will lie outside of the 24 bit addressing range of the offset based
+-version of subroutine call instruction.

++allows all avr32 instructions.
