        * added support for -mpcrel (PC relative addressing for m68k)
        based on code done by Michael Tiemann  <tiemann@axon.cygnus.com>.
        * invoke.texi (m68000 options): Add documentation for -mpcrel flag.
        * m68k.c (print_operand_address): Handle 32-bit PIC case.
        (comments for general_src_operand): Add some explanation
        about EXTRA_CONSTRAINTS.
        (OVERRIDE_OPTIONS): Enable -fPIC in combination with -mpcrel.

        (LEGITIMATE_PIC_OPERAND_P): Re-derive from m68k.h case.
        * m68k.h (LEGITIMATE_PIC_OPERAND_P): Fix delete-o.
        (INDIRECTABLE_1_ADDRESS): Delete spurious '/' at end of macro.
        (OVERRIDE_OPTIONS): Change behavior so that -mpcrel implies -fpic
        if not already set.
        (OVERRIDE_OPTIONS): Merge in changes from m68k.h.
        * m68k.h (TARGET_PCREL): New target flag.
        (TARGET_SWITCHES): Add "pcrel" as a recognized switch.
        (OVERRIDE_OPTIONS): Add checks for -mpcrel.
        (LEGITIMATE_PIC_OPERAND_P): Don't normally accept anything that
        contains a SYMBOL_REF.  Relax this constraint during reload, since
        we want to use the predicates, not reload's built-in concept of a
        valid memory address, to control what insns need reloading.
        (EXTRA_CONSTRAINT): Define constraints to accept pc-relative
        operands (essentially 'g', 'm', and 's' under normal circumstances).

        (memory_src_operand): Similar, for memory_operands.
        (pcrel_address): New predicate to accept the special case of a
        pc-relative address.
        * m68k.md (many patterns): Rewrite common SImode, HImode, and
        QImode insns to accept *_src_operand instead of *_operand where
        pc-relative operands can fit.  For example, a pc-relative operand
        can be used as a memory source operand for addsi3, but not as a
        memory destination.
        * hp320.h linux.h m68kv4.h (LEGITIMATE_PIC_OPERAND_P) as in m68k.h.
