++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.
++
++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.

++/*
++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.

++/* Passing Arguments in Registers */

++A C expression that controls whether a function argument is passed

++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.

++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.

+Hi,
+
+The attached patch makes sure that we create smaller object code for
+simple switch statements. We just make sure to flatten the switch
+statement into an if-else chain, basically.
+
+This fixes a size-regression as compared to gcc-3.4, as can be seen
+below.
+
+2007-04-15 Bernhard Fischer <..>
+
+ * stmt.c (expand_case): Do not create a complex binary tree when
+ optimizing for size but rather use the simple ordered list.
+ (emit_case_nodes): do not emit jumps to the default_label when
+ optimizing for size.
+
+Not regtested so far.
+Comments?
+
+Attached is the test switch.c mentioned below.

+
+ This patch brings over a few features from MirBSD:
+ * -fhonour-copts
+ If this option is not given, it's warned (depending
+ on environment variables). This is to catch errors
+ of misbuilt packages which override CFLAGS themselves.
+ * -Werror-maybe-reset
+ Has the effect of -Wno-error if GCC_NO_WERROR is
+ set and not '0', a no-operation otherwise. This is
+ to be able to use -Werror in "make" but prevent
+ GNU autoconf generated configure scripts from
+ freaking out.
+ * Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
+ the default for -O2/-Os, because they trigger gcc bugs
+ and can delete code with security implications.
+
+ This patch was authored by Thorsten Glaser <tg@mirbsd.de>
+ with copyright assignment to the FSF in effect.
