Subject: [PATCH] 	* config/mips/mips.md (*extenddi_truncate<mode>, 
 *extendsi_truncate<mode>): Change type attribute to move_type 	with
 shift_shift.  Split out code handling exts from here ... 
 (*extend<GPR:mode>_truncate<SHORT:mode>_exts): ... to this new 
 pattern. 	(*extendhi_truncateqi): Change type attribute to move_type
 with 	shift_shift.  Split out code handling exts from here ... 
 (*extendhi_truncateqi_exts): ... to this new pattern.
