+ 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'. */
