	* m68k.md (adddi_dilshr32): Allow all operands to be registers too.
	(adddi_dishl32): Similarly.

	* cse.c (invalidate_skipped_block): Call invalidate_from_clobbers
	for each insn in the skipped block.

	* reload1.c (reload_as_needed): Verify that the insn satisfies its
	constraints after replacing a register address with an autoincrement
	address for reload inheritance purposes.

	* i386.md (doubleword shifts): Avoid namespace pollution.

Wed Dec 30 23:00:28 1998  David O'Brien  <obrien@NUXI.com>

1998-12-30  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* loop.c (check_dbra_loop): While reversing the loop, if the
	comparison value has a VOID mode use the mode of the other operand
	to compute the mask.
