Thanks for the tip.  And, since I don't want to deal with those peculiar 
back-ends anymore :-), I simply added a new state numbered 2 to 
the 'nopeepholes' parameter (after checking that every call to 
final_scan_insn currently uses 0 or 1).

Is this ok with you, Zack (after the usual testing of course)?  Or do you 
want me to add "#if DELAY_SLOTS/#endif" pairs?

        * final.c (output_in_slot): New global variable.
        (final_scan_insn): Add new state '2' to the 'nopeepholes' parameter.
        Pass 2 as 'nopeepholes' to self for insns in a SEQUENCE.  Set
	'output_in_slot' before invoking output_asm_insn.
        (output_asm_insn): Add a space after the tab if 'output_in_slot'
        is set.
	* config/sparc/sparc.c (output_return): Pass 2 as 'nopeepholes' to
	final_scan_insn.
	(output_sibcall): Likewise.
