-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
-`(* targetm.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'.  */
