++ Source files for reload pass need to be strict.
++ After reload, it makes no difference, since pseudo regs have

++ 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'. */

++ 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'. */
