And then I can recode the

(match_operand:QI 1 "general_operand" ""))]
to cope with the movqi requirements defined in the gcc manual.
Hmmm... wondering who all these xxx_operand functions are defined, and
where they are documented...
Is this the right way to go?

Changing "m" to "Q", narrowing the address modes
Changing "r" to "+r", (register is globbered)
and of course making the swpb call..
Gcc compiles, but does a segfault while compiling ARM programs.

Hmmm... I have thought about that. But how do the compiler know if the
byte address is even or odd? Every time testing the LSB of the address
and making co
found arm.md and the moveqi insns, but because of the different
addressing modes of strb and swpb, its not easy to make the change.
And there must be a compiler option for this, too.
Could somebody please tell me how to implement this change?
