++
++ It is not necessary for this macro 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. The way to implement that is to define 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 `movMODE' instruction pattern support moves between the
++ register and any other hard register for which the mode is OK; and
++ that moving a value into the register and back out not alter it.
++
++ Since the same instruction used to move `SImode' 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. */

++ (e.g., those with symbolic address on the RT, and those with

++ some cases, both an intermediate and a scratch register are
++ required.
++
++ You should define these macros to indicate to the reload phase
++ that it may need to allocate at least one register for a reload in

++ directly copied to or from a register of CLASS in MODE without
++ requiring a scratch register. Do not define this macro if it
++ would always return `NO_REGS'.
++
++ If a scratch register is required (either with or without an
++ intermediate register), you should define patterns for
++ `reload_inM' or `reload_outM', as required (*note Standard
++ Names::.. These patterns, which will normally be implemented with
++ a `define_expand', should be similar to the `movM' patterns,

++ 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. *Note Assembler Format::.
++
++ 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
