4798 + that any pseudo-register that has not been allocated a hard register is
4799 + considered a memory reference. In contexts where some kind of register is
4800 + required, a pseudo-register with no hard register must be rejected.
4802 + The non-strict variant is used in other passes. It must be defined to
4803 + accept all pseudo-registers in every context where some kind of register is
4806 + Compiler source files that want to use the strict variant of this macro
4807 + define the macro `REG_OK_STRICT'. You should use an `#ifdef REG_OK_STRICT'
4808 + conditional to define the strict variant in that case and the non-strict
4809 + variant otherwise.
4811 + Subroutines to check for acceptable registers for various purposes (one for
4812 + base registers, one for index registers, and so on) are typically among the
4813 + subroutines used to define `GO_IF_LEGITIMATE_ADDRESS'. Then only these
4814 + subroutine macros need have two variants; the higher levels of macros may be
4815 + the same whether strict or not.
4817 + Normally, constant addresses which are the sum of a `symbol_ref' and an
4818 + integer are stored inside a `const' RTX to mark them as constant.
4819 + Therefore, there is no need to recognize such sums specifically as
4820 + legitimate addresses. Normally you would simply recognize any `const' as
4823 + Usually `PRINT_OPERAND_ADDRESS' is not prepared to handle constant sums that
4824 + are not marked with `const'. It assumes that a naked `plus' indicates
4825 + indexing. If so, then you *must* reject such naked constant sums as
4826 + illegitimate addresses, so that none of them will be given to
4827 + `PRINT_OPERAND_ADDRESS'.
4829 + On some machines, whether a symbolic address is legitimate depends on the
4830 + section that the address refers to. On these machines, define the macro
4831 + `ENCODE_SECTION_INFO' to store the information into the `symbol_ref', and
4832 + then check for it here. When you see a `const', you will have to look
4833 + inside it to find the `symbol_ref' in order to determine the section.
4835 + The best way to modify the name string is by adding text to the beginning,
4836 + with suitable punctuation to prevent any ambiguity. Allocate the new name
4837 + in `saveable_obstack'. You will have to modify `ASM_OUTPUT_LABELREF' to
4838 + remove and decode the added text and output the name accordingly, and define
4839 + `STRIP_NAME_ENCODING' to access the original name string.
4841 + You can check the information stored here into the `symbol_ref' in the
4842 + definitions of the macros `GO_IF_LEGITIMATE_ADDRESS' and
4843 + `PRINT_OPERAND_ADDRESS'. */
