-/* Try machine-dependent ways of modifying an illegitimate address
-   to be legitimate.  If we find one, return the new, valid address.
-   This macro is used in only one place: `memory_address' in explow.c.
-
-   OLDX is the address as it was before break_out_memory_refs was called.
-   In some cases it is useful to look at this to decide what needs to be done.
-
-   MODE and WIN are passed so that this macro can use
-   GO_IF_LEGITIMATE_ADDRESS.
-
-   It is always safe for this macro to do nothing.  It exists to recognize
-   opportunities to optimize the output.
-
-   For the 80386, we handle X+REG by loading X into a register R and
-   using R+REG.  R will go in a general reg and indexing will be used.
-   However, if REG is a broken-out memory address or multiplication,
-   nothing needs to be done because REG can certainly go in a general reg.
-
-   When -fpic is used, special handling is needed for symbolic references.
-   See comments by legitimize_pic_address in i386.c for details.  */
