339 +If defined, a function that outputs the assembler code for entry to a
340 +function. The prologue is responsible for setting up the stack frame,
341 +initializing the frame pointer register, saving registers that must be
342 +saved, and allocating size additional bytes of storage for the
343 +local variables. size is an integer. file is a stdio
344 +stream to which the assembler code should be output.
345 +
346 +The label for the beginning of the function need not be output by this
347 +macro. That has already been done when the macro is run.
348 +
349 +To determine which registers to save, the macro can refer to the array
350 +regs_ever_live: element r is nonzero if hard register
351 +r is used anywhere within the function. This implies the function
352 +prologue should save register r, provided it is not one of the
353 +call-used registers. (TARGET_ASM_FUNCTION_EPILOGUE must likewise use
354 +regs_ever_live.)
355 +
356 +On machines that have ``register windows'', the function entry code does
357 +not save on the stack the registers that are in the windows, even if
358 +they are supposed to be preserved by function calls; instead it takes
359 +appropriate steps to ``push'' the register stack, if any non-call-used
360 +registers are used in the function.
361 +
362 +On machines where functions may or may not have frame-pointers, the
363 +function entry code must vary accordingly; it must set up the frame
364 +pointer if one is wanted, and not otherwise. To determine whether a
365 +frame pointer is in wanted, the macro can refer to the variable
366 +frame_pointer_needed. The variable's value will be 1 at run
367 +time in a function that needs a frame pointer. (see Elimination).
368 +
369 +The function entry code is responsible for allocating any stack space
370 +required for the function. This stack space consists of the regions
371 +listed below. In most cases, these regions are allocated in the
372 +order listed, with the last listed region closest to the top of the
373 +stack (the lowest address if STACK_GROWS_DOWNWARD is defined, and
374 +the highest address if it is not defined). You can use a different order
375 +for a machine if doing so is more convenient or required for
376 +compatibility reasons. Except in cases where required by standard
377 +or by a debugger, there is no reason why the stack layout used by GCC
378 +need agree with that used by other compilers for a machine.

5378 + register; they have to come from a pc relative load. The constant
5379 + must therefore be placed in the addressable range of the pc
5380 + relative load. Depending on the precise pc relative load
5381 + instruction the range is somewhere between 256 bytes and 4k. This
5382 + means that we often have to dump a constant inside a function, and
5383 + generate code to branch around it.
5384 +
5385 + It is important to minimize this, since the branches will slow
5386 + things down and make the code larger.
5387 +
5388 + Normally we can hide the table after an existing unconditional
5389 + branch so that there is no interruption of the flow, but in the
5390 + worst case the code looks like this:
5391 +
5392 + lddpc rn, L1
5393 + ...
5394 + rjmp L2
5395 + align
5396 + L1: .long value
5397 + L2:
5398 + ...
5399 +
5400 + lddpc rn, L3
5401 + ...
5402 + rjmp L4
5403 + align
5404 + L3: .long value
5405 + L4:
5406 + ...
5407 +
5408 + We fix this by performing a scan after scheduling, which notices
5409 + which instructions need to have their operands fetched from the
5410 + constant table and builds the table.
5411 +
5412 + The algorithm starts by building a table of all the constants that
5413 + need fixing up and all the natural barriers in the function (places
5414 + where a constant table can be dropped without breaking the flow).
5415 + For each fixup we note how far the pc-relative replacement will be
5416 + able to reach and the offset of the instruction into the function.
5417 +
5418 + Having built the table we then group the fixes together to form
5419 + tables that are as large as possible (subject to addressing
5420 + constraints) and emit each table of constants after the last
5421 + barrier that is within range of all the instructions in the group.
5422 + If a group does not contain a barrier, then we forcibly create one
5423 + by inserting a jump instruction into the flow. Once the table has
5424 + been inserted, the insns are then modified to reference the
5425 + relevant entry in the pool.
5426 +
5427 + Possible enhancements to the algorithm (not implemented) are:
5428 +
5429 + 1) For some processors and object formats, there may be benefit in
5430 + aligning the pools to the start of cache lines; this alignment
5431 + would need to be taken into account when calculating addressability

8674 +/*
8675 +Define this if you wish to imitate the way many other C compilers handle
8676 +alignment of bit-fields and the structures that contain them.
8677 +
8678 +The behavior is that the type written for a bit-field (int,
8679 +short, or other integer type) imposes an alignment for the
8680 +entire structure, as if the structure really did contain an ordinary
8681 +field of that type. In addition, the bit-field is placed within the
8682 +structure so that it would fit within such a field, not crossing a
8683 +boundary for it.
8684 +
8685 +Thus, on most machines, a bit-field whose type is written as int
8686 +would not cross a four-byte boundary, and would force four-byte
8687 +alignment for the whole structure. (The alignment used may not be four
8688 +bytes; it is controlled by the other alignment parameters.)
8689 +
8690 +If the macro is defined, its definition should be a C expression;
8691 +a nonzero value for the expression enables this behavior.
8692 +
8693 +Note that if this macro is not defined, or its value is zero, some
8694 +bit-fields may cross more than one alignment boundary. The compiler can
8695 +support such references if there are insv, extv, and
8696 +extzv insns that can directly reference memory.
8697 +
8698 +The other known way of making bit-fields work is to define
8699 +STRUCTURE_SIZE_BOUNDARY as large as BIGGEST_ALIGNMENT.
8700 +Then every structure can be accessed with fullwords.
8701 +
8702 +Unless the machine has bit-field instructions or you define
8703 +STRUCTURE_SIZE_BOUNDARY that way, you must define
8704 +PCC_BITFIELD_TYPE_MATTERS to have a nonzero value.
8705 +
8706 +If your aim is to make GCC use the same conventions for laying out
8707 +bit-fields as are used by another compiler, here is how to investigate
8708 +what the other compiler does. Compile and run this program:
8709 +
8710 +struct foo1
8711 +{
8712 + char x;
8713 + char :0;
8714 + char y;
8715 +};
8716 +
8717 +struct foo2
8718 +{
8719 + char x;
8720 + int :0;
8721 + char y;
8722 +};
8723 +
8724 +main ()
8725 +{
8726 + printf ("Size of foo1 is %d\n",
8727 + sizeof (struct foo1));
8728 + printf ("Size of foo2 is %d\n",
8729 + sizeof (struct foo2));
8730 + exit (0);
8731 +}
8732 +
8733 +If this prints 2 and 5, then the compiler's behavior is what you would
8734 +get from PCC_BITFIELD_TYPE_MATTERS.

9088 +
9089 + #define HARD_REGNO_MODE_OK(REGNO, MODE) 1
9090 +
9091 +You need not include code to check for the numbers of fixed registers,
9092 +because the allocation mechanism considers them to be always occupied.
9093 +
9094 +On some machines, double-precision values must be kept in even/odd
9095 +register pairs. You can implement that by defining this macro to reject
9096 +odd register numbers for such modes.
9097 +
9098 +The minimum requirement for a mode to be OK in a register is that the
9099 +mov[mode] instruction pattern support moves between the
9100 +register and other hard register in the same class and that moving a
9101 +value into the register and back out not alter it.
9102 +
9103 +Since the same instruction used to move word_mode will work for
9104 +all narrower integer modes, it is not necessary on any machine for
9105 +HARD_REGNO_MODE_OK to distinguish between these modes, provided
9106 +you define patterns movhi, etc., to take advantage of this. This
9107 +is useful because of the interaction between HARD_REGNO_MODE_OK
9108 +and MODES_TIEABLE_P; it is very desirable for all integer modes
9109 +to be tieable.
9110 +
9111 +Many machines have special registers for floating point arithmetic.
9112 +Often people assume that floating point machine modes are allowed only
9113 +in floating point registers. This is not true. Any registers that
9114 +can hold integers can safely hold a floating point machine
9115 +mode, whether or not floating arithmetic can be done on it in those
9116 +registers. Integer move instructions can be used to move the values.
9117 +
9118 +On some machines, though, the converse is true: fixed-point machine
9119 +modes may not go in floating registers. This is true if the floating
9120 +registers normalize any value stored in them, because storing a
9121 +non-floating value there would garble it. In this case,
9122 +HARD_REGNO_MODE_OK should reject fixed-point machine modes in
9123 +floating registers. But if the floating registers do not automatically
9124 +normalize, if you can store any bit pattern in one and retrieve it
9125 +unchanged without a trap, then any machine mode may go in a floating
9126 +register, so you can define this macro to say so.
9127 +
9128 +The primary significance of special floating registers is rather that
9129 +they are the registers acceptable in floating point arithmetic
9130 +instructions. However, this is of no concern to
9131 +HARD_REGNO_MODE_OK. You handle it by writing the proper
9132 +constraints for those instructions.
9133 +
9134 +On some machines, the floating registers are especially slow to access,
9135 +so that it is better to store a value in a stack frame than in such a
9136 +register if floating point arithmetic is not being done. As long as the
9137 +floating registers are not in class GENERAL_REGS, they will not
9138 +be used unless some pattern's constraint asks for one.

9854 +stack. If a variable number of bytes is passed, it is zero, and
9855 +argument popping will always be the responsibility of the calling function.
9856 +
9857 +On the VAX, all functions always pop their arguments, so the definition
9858 +of this macro is STACK_SIZE. On the 68000, using the standard
9859 +calling convention, no functions pop their arguments, so the value of
9860 +the macro is always 0 in this case. But an alternative calling
9861 +convention is available in which functions that take a fixed number of
9862 +arguments pop them but other functions (such as printf) pop
9863 +nothing (the caller pops all). When this convention is in use,
9864 +FUNTYPE is examined to determine whether a function takes a fixed

9891 +/*
9892 +A C expression that controls whether a function argument is passed
9893 +in a register, and which register.
9894 +
9895 +The arguments are CUM, which summarizes all the previous
9896 +arguments; MODE, the machine mode of the argument; TYPE,
9897 +the data type of the argument as a tree node or 0 if that is not known
9898 +(which happens for C support library functions); and NAMED,
9899 +which is 1 for an ordinary argument and 0 for nameless arguments that
9900 +correspond to '...' in the called function's prototype.
9901 +TYPE can be an incomplete type if a syntax error has previously
9902 +occurred.
9903 +
9904 +The value of the expression is usually either a reg RTX for the
9905 +hard register in which to pass the argument, or zero to pass the
9906 +argument on the stack.
9907 +
9908 +For machines like the VAX and 68000, where normally all arguments are
9909 +pushed, zero suffices as a definition.
9910 +
9911 +The value of the expression can also be a parallel RTX. This is
9912 +used when an argument is passed in multiple locations. The mode of the
9913 +of the parallel should be the mode of the entire argument. The
9914 +parallel holds any number of expr_list pairs; each one
9915 +describes where part of the argument is passed. In each
9916 +expr_list the first operand must be a reg RTX for the hard
9917 +register in which to pass this part of the argument, and the mode of the
9918 +register RTX indicates how large this part of the argument is. The
9919 +second operand of the expr_list is a const_int which gives
9920 +the offset in bytes into the entire argument of where this part starts.
9921 +As a special exception the first expr_list in the parallel
9922 +RTX may have a first operand of zero. This indicates that the entire
9923 +argument is also stored on the stack.
9924 +
9925 +The last time this macro is called, it is called with MODE == VOIDmode,
9926 +and its result is passed to the call or call_value
9927 +pattern as operands 2 and 3 respectively.
9928 +
9929 +The usual way to make the ISO library 'stdarg.h' work on a machine
9930 +where some arguments are usually passed in registers, is to cause
9931 +nameless arguments to be passed on the stack instead. This is done
9932 +by making FUNCTION_ARG return 0 whenever NAMED is 0.
9933 +
9934 +You may use the macro MUST_PASS_IN_STACK (MODE, TYPE)
9935 +in the definition of this macro to determine if this argument is of a
9936 +type that must be passed in the stack. If REG_PARM_STACK_SPACE
9937 +is not defined and FUNCTION_ARG returns nonzero for such an
9938 +argument, the compiler will abort. If REG_PARM_STACK_SPACE is
9939 +defined, the argument will be computed in the stack and then loaded into

10292 +It usually pays to define several simpler macros to serve as
10293 +subroutines for this one. Otherwise it may be too complicated to
10294 +understand.
10295 +
10296 +This macro must exist in two variants: a strict variant and a
10297 +non-strict one. The strict variant is used in the reload pass. It
10298 +must be defined so that any pseudo-register that has not been
10299 +allocated a hard register is considered a memory reference. In
10300 +contexts where some kind of register is required, a pseudo-register
10301 +with no hard register must be rejected.
10302 +
10303 +The non-strict variant is used in other passes. It must be defined to
10304 +accept all pseudo-registers in every context where some kind of
10305 +register is required.
10306 +
10307 +Compiler source files that want to use the strict variant of this
10308 +macro define the macro REG_OK_STRICT. You should use an
10309 +#ifdef REG_OK_STRICT conditional to define the strict variant
10310 +in that case and the non-strict variant otherwise.
10311 +
10312 +Subroutines to check for acceptable registers for various purposes (one
10313 +for base registers, one for index registers, and so on) are typically
10314 +among the subroutines used to define GO_IF_LEGITIMATE_ADDRESS.
10315 +Then only these subroutine macros need have two variants; the higher
10316 +levels of macros may be the same whether strict or not.
10317 +
10318 +Normally, constant addresses which are the sum of a symbol_ref
10319 +and an integer are stored inside a const RTX to mark them as
10320 +constant. Therefore, there is no need to recognize such sums
10321 +specifically as legitimate addresses. Normally you would simply
10322 +recognize any const as legitimate.
10323 +
10324 +Usually PRINT_OPERAND_ADDRESS is not prepared to handle constant
10325 +sums that are not marked with const. It assumes that a naked
10326 +plus indicates indexing. If so, then you must reject such
10327 +naked constant sums as illegitimate addresses, so that none of them will
10328 +be given to PRINT_OPERAND_ADDRESS.
10329 +
10330 +On some machines, whether a symbolic address is legitimate depends on
10331 +the section that the address refers to. On these machines, define the
10332 +macro ENCODE_SECTION_INFO to store the information into the
10333 +symbol_ref, and then check for it here. When you see a
10334 +const, you will have to look inside it to find the
10335 +symbol_ref in order to determine the section.
10336 +
10337 +The best way to modify the name string is by adding text to the
10338 +beginning, with suitable punctuation to prevent any ambiguity. Allocate
10339 +the new name in saveable_obstack. You will have to modify
10340 +ASM_OUTPUT_LABELREF to remove and decode the added text and
10341 +output the name accordingly, and define STRIP_NAME_ENCODING to
10342 +access the original name string.
10343 +
10344 +You can check the information stored here into the symbol_ref in
10345 +the definitions of the macros GO_IF_LEGITIMATE_ADDRESS and
10346 +PRINT_OPERAND_ADDRESS.
