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'. */ - -#ifdef REG_OK_STRICT -#define REG_OK_STRICT_P 1 -#else -#define REG_OK_STRICT_P 0 -#endif - -#define GO_IF_LEGITIMATE_ADDRESS(MODE, X, LABEL) \ - do \ - { \ - if (frv_legitimate_address_p (MODE, X, REG_OK_STRICT_P, \ - FALSE, FALSE)) \ - goto LABEL; \ - } \ - while (0) - /* A C expression that is nonzero if X (assumed to be a `reg' RTX) is valid for use as a base register.
