+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.

+/* 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.

+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.
