+   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'.  */
